Hi all,

Please use this thread as a place to consolidate feature requests for the QCAR SDK. If there is something missing that is holding back your development efforts, we'd like to know about it! If you're having trouble with an existing feature and would like more sample code to help you get started, we'd like to know about that too.

Looking forward to your input, thanks!

Target Management System API

Some sort of API to generate new image targets on the fly.
This could be either built in or via the Target Management web service.

Maybe you could outline reason why it may not be add it to the SDK?

I know it may slow down the app etc. but it'd be good to have the choice and who knows what kind of use cases people would com up with.

I like the idea of a user being able to take a picture of something and then use that picture for tracking.

The image could be thrown up to the Target Management web service using an API of some sort and the .xml and .dat files would then be available to download for that particular image. Current API's could then be used to swap in those files and start tracking using the custom images.

hi,
i have a few features at the moment that i would really like to see in a future version.

1. a unified version of the unity plugin for both, android and ios, or at least a clear step-by-step guide on how to implement both plugins in one single project. multi platform publishing form one single project is one of the best features of unity and you should definitely take advantage of that!

2. it would be great to have a feature that autoadjusts the positions of the parts of a multi target in runtime. as it is sometimes hard to match the real position of the single targets exactly with the multi target definition a solution similar to what elecman did here could be a great improvement and used for fine tuning the position. i don't know if you actually have something like that already implemented in your code but if not maybe you want to consider it.

3. non rectangular trackables. i'm mainly interested in triangular trackables that can be used to build up more complex multi targets out of them based on a triangulated mesh.

4. is there any possibility to allow us to manually set/delete feature points in the TMS? i'm working with pictures and in many cases it would be really helpful to be able to do something like this directly in the TMS not just via image editing.

i hope i made myself clear, if not please get in contact with me.
best,
stefan

[U" />Larger tracking distance for Frame/pattern-markers[/U" />
I'd just like to add that for various applications, we at twnkls would also REALLY like (frame) markers to be detectable/trackable at larger distances (as with ARToolkit, for example).

This is one of the things we just had to ask for when we met the Qualcomm AR team at ISMAR this year: we are developing several novel fusion algorithms that combine the vision tracking with the device's sensors, and the ability to track markers at a greater distance would really add great value. In fact so much so that with the current max distance, we would have to use an alternative tracker, which is certainly not what we want.

For these scenarios, we have no problem whatsoever with losing the picture in the marker, so an alternative marker type would be a good solution.

[U" />More ID's for pattern markers[/U" />
Tracking at larger distances would also benefit our SocializAR application, for which we would also appreciate a larger number of ID's (2000 or more, so that we can also handle larger conventions with our application).

Re: Wish List

December 25, 2011 - 12:46pm #655

hi,
here is another one.
- the ability to convert manually in unity arranged image targets to one multi target and generate the according .xml code.
i guess this could be done with a editor script but it would be a nice thing to have it already implemented in the QCAR package.

EDIT1:
- a "debug" modus where the feature points, that are actually found, can be visualized.
- a feedback on how good the actual performance of the tracking is (on the running app). could be a ranking system like in the TMS.

2 more wishes on the wishlist itself:
- a system where users can rank wishes to give it higher priority similar to this.
- feedback from Qualcomm on what wishes are probably going to be considered. i know you won't say anything for sure but some feedback would be nice.

and a completely different one:
- what do you think about a webinar or something similar once in a while. this would be a much more direct way to communicate and learn some new features.

Implementing a way to load several model formats, such as obj or 3ds. This is the best AR-SDK I have used so far, but since you are basically required to use a 3D-Engine to display models, there is a lot of overhead. Just looking at the GLES forum here, I see a whole lot of threads about using models, that aren't in a native GL format (which doesn't surprise, since as far as I know, modellers such as Blender or Maya don't support exporting in this format).

It would also be cool to capsule the required initialization logic into something much simpler as it is now. Yes, the sample projects provide the necessary code, but if you had it to develop by yourself it would probably take very much time to do it as efficiently as it is there. Its like 400 lines of code in the main activity, plus the custom GLSurfaceView, plus the required native methods. I could never figure that out by myself.

Re: Wish List

From a question I had, we'd like this to be possible:

Quote:

Next question is would there be any way for us to control the frequency that the framebuffer is analyzed for tracking? So that we could, for example, slow down the tracking frequency if the rest of our app is slowing down -- try to do a bit of load balancing. Is that what Camera Device Mode deals with? Would we be able to build off of that to create our own dynamic system?

Re: Wish List

January 31, 2012 - 5:27am #645

I've already integrated Unity3D in Eclipse ;). I don't see as the best solution.

For Example:

- when integrating with eclipse, the generated StagingArea for the Libary has a size of 33,7 MB, making the final APK also big (21,90MB).
When you do not integrate with eclipse (build only with unity) the app are smaller (9MB). WHY?

- I have a main activity using a button then i launch the unity activity, but i need to finish it and go back to the previous activity, but instead the whole app is closed.

- How can my Activity communicate with the AR player Activity?

Re: Wish List

April 6, 2012 - 11:22pm #636

Im using QCAR a little beyond its intended purposes (for small

1) tracker preview texture.

I assume the tracker converts the camera image to grayscale, then possibly thresholds, sharpens or runs other image processing on it. This would be really useful to see during development and testing of markers. I have a few markers I think dont work at certain distances because fine details or contrast are lost in certain lighting conditions, but I cant know for sure. It also would reveal useful feedback about how reflections, exposure, focus, rotation and numerous other environmental conditions are impacting the computer-vision side of things. Eventually it would even be good to control things such as adaptive thresholding scale, but for now just instantly visually identifying good/bad markers and environments would be a boon.

2) resolution-independent trackable creator.

As I mentioned I use small markers. To be realistic about the detail that can be resolved, and hence recognised, I should only be giving the trackable creator low rez images, or images without much fine detail (de-focussed slightly). I find these two cases create substantially different trackables:

For low rez images, much of the outer edges of the images are not used. This issue manifests most in multimarker strips (needed to simulate a curve) where sometimes only a narrow margin in the center of the strip has trackable features. I imagine this is related to the "box" size in pixels required around any feature, but scaling up the image leads to the issues in the second half of this suggestion.

With higher rez images it feels (and this is a total guess) like the trackable creator is still trying to identify small local features, even when I blur them out to encourage finding larger scale structures. In most cases low resolution images work far better than the same image upscaled. It would be good if the creator could assess the resolution of an image vs its features, and choose a range of structure scales based on a lower 'floor' limit at which high quality features begin, independent of starting resolution.

These small-size marker issues might also impact people working at a distance (both having the markers represent a smaller than average proportion of the camera image). A manual way of identifying these cases might be to be able to set the average marker distance as a proportion of the camera image. In my case this would be the marker taking up 1/7 to 1/4 the height of the camera image, which I suspect is a lot smaller than most uses.

Hi, copy paste from another thread:

Quote:

Hi everybody,
I'm looking for a feature very useful for our users, to let them know the current quality of the current tracking. It could help them to keep capturing trackers without losing it.
I've already seen a thread talking about this feature, but I'm sure somewhere it's possible to retrieve this information.

Of course this information will be available only when the status is on TRACKING mode, not on detection.

A float from 0 to 1, or at least some different levels (poor, good, perfect) will be good enough.

Thanks !

Re: Wish List

I know this seems like a repeat of a couple requests already in the thread, but I consider it more of an aggregate request.

Wish List

July 3, 2012 - 11:46am #629

-Function to export a Config.xml file (for Multi Targets) for the setup which has been created at runtime using the API.
-Ability to create a trackable offline by taking a picture with the phone camera and then applying perspective and lens correction to it without using the online service. This will greatly enhance user experience as the user is able to take a picture from any 2d surface and use that as a marker without the need to be a developer and know how to compile a new project. Much faster too.
-Open source.
-Faster marker detection (comparable to String) and support for multithreading. Faster tracking is always better and mobile devices have multiple processors these days. Perhaps Vuforia could take advantage of this?
-If a marker is lost with fast physical camera movements, the marker is still tagged as being tracked for a fraction of a second. This causes the 3d augmentation to be displayed while it should not. I find this very distracting and it breaks the AR illusion. If this is a "feature", please give the user an option to enable or disable this. If this is not a feature, please increase the speed of the marker de-recognition. The speed of de-recognition (marker being lost) is just as important as marker recognition (marker being found). See thread here: http://ar.qualcomm.at/node/2000994
-Camera preview in Unity3d Editor.
-Ability to create a marker lost and marker found event in the Unity3d Editor.
-If the virtual button is occluded by moving the camera so it is partially out of view, the button will still be triggered. This shouldn't be happening. It is known where the camera is in relation to the marker and it's virtual buttons. So the software can test whether or not the button is fully inside the camera view frustum, partially occluded by it, or totally out of it.
-Support for FOCUS_MODE_CONTINUOUS_VIDEO and FOCUS_MODE_CONTINUOUS_PICTURE
-Light sampling. Get the average color of the camera image at the marker location (color value on per-marker basis) to change the color of the augmentation for better in-scene blending.

Edit:
-Support PC and Mac as well, instead of only IOS and Android.

Edit2:
-It would be nice if in Unity3d a marker object did not rely on a script. Let me explain. If a marker gets lost, all the children of the marker object need to be disabled. Currently this is done by getting all the renderers of the children and disabling those. You can not use SetActiveRecursively() because this will disable the parent marker object itself, which will disable it's scripts. Because it's scripts are disabled, it cannot detect when the marker is back into view and it is lost forever. There are several reasons why I want to use SetActiveRecursively() and one of them is because String uses that and my project is compatible with both String and Vuforia. Using separate code paths to handle marker visibility for String and Vuforia caused me a lot of headaches and a uniform solution would be nice. Another reason is because it is easier to see if a marker is tracked or not by simply looking if the marker object is active or not. With this logic it is not necessary to have separate code to track which markers are currently visible. The renderer cannot be used with this because the marker object itself doesn't have a renderer.
-Mark a Frame Marker as LOST or not tracked when one of it's edges is nearly touching or beyond the physical camera view frustum. I noticed that the marker pose often contains large errors while being moved out of view before it is marked as LOST. These errors can be filtered out if the marker obstruction is caused by the marker moving out of the field of view.

Edit3:
-Don't download the camera profile file at first startup but use an off-line database which comes with the SDK for that.
-If the online camera profile is used, display a message that the default profile is used instead if the customized one if an internet connection is not available.

Edit4:
-Do not display a warning in the Unity3d editor log that multiple data sets are available. Only display a warning or error if they are tried to be used at the same time.
-Add callback function (which can be added to any custom user script) which is called once when Vuforia is initialized. This is to make sure that the marker creation code is ready to be used.
-Support for use of image target dataset loading/activation in the Unity3d editor. This is helpful for debugging.
-Support for generating frame markers at runtime in the Unity3d editor. This is helpful for debugging.
-Add an integer variable to each image target which is guaranteed to stay the same for each program run, for each individual marker. This instead of using a string name for the marker. Comparing strings to figure out whether or not a marker is tracked is slow. Besides, frame markers use integers to indicate it's "name", so image targets could use the same logic.

Edit6:
-A video texture which does not contain a black border.
-Add some documentation about how to properly UV map the video texture.
-Remove the need for obscure UV coordinates to get the video texture right. The range should be between 0 and 1 as it is a normal plane.
-Add callback for IsVideoBackgroundInfoAvailable() so I don't have to keep calling it in the Update() function.
-Add more performance efficient example for the video texture code such as the use of a Mobile/Unlit shader which doesn't need a light source and not setting up the entire mesh every frame in the Update() function.

Edit7:
-Ability to change the marker size using the online creation tool if the trackable is already created.
-Ability to set exposure time to a fixed value to force a high video frame rate in low light conditions.
-Get SetSize() to work in Unity3d

Edit8:
-SLAM implementation, but recognizing and tracking markers in the same scene as well.
-Fix bug when using GetSize() on a marker with x size 1.0
-Add documentation specifically for Unity3d since many functions and methods are different in there.
-Replace all QCAR references in the code with Vuforia.
-Improve handling of partially occluded Frame Markers. Currently partially occluded frame markers will have severe pose errors when the marker is occluded by straight surface parallel to the marker.

Edit 9:
-If CameraDevice.Instance.Stop() / Start() is used multiple times, it introduces a significant latency between real camera movement and updating of the camera texture.
-Please fix the new forum numerous bugs.

-Please fix the new forum numerous bugs.

Edit 10:
-I would like to do some additional image recognition on the camera feed. Fetching the camera texture in Unity3d and doing math on the texture in C# is going to be far too slow. Why not release part of the native plugin which converts the camera feed to the correct grayscale format. Then you can have one function call which does the ultra-secret proprietary corporate protected pose recognition, and another one where you can do your own image recognition. This way I can combine SLAM and marker based detection which would enable for some really cool special effects.

I know this has been mentioned before, but could i repeat the request for being able to put frame markers in multitargets. This is especially important in cases where multiple small multitargets are being used, or in cases where a multitarget must be found when it is in front of an image target.

I am having to write my own multitarget system to do this but as it is not really properly integrated, it don't work as well as it could or should. Especially on dropout with the frame freeze that occurs on dropout. And yes I know about UCS, but it doesn't cover my case.

I have a request. I use unity3d and loading the ARCamera takes a while (as i have alot of image targets), like 30seconds to 14 minute.

Normally this would not be a problem if loaded at the begnning. But I try to use the ARCamera in a later scene so a hang (which is waht that looks like) is not a good idea.

And trying to load it at the beginning of the application and just turn off QCAR behaviour then turn it back on in the proper scene (Using DontDestoryOnLoad()) does not work as the Dictionary get lost in the process (aka all my loaded imagetargets)

So my request is make it possible to load the ARCamera in the scene and have it persist all throughout the different scenes without loosing its whole database of trackables. THen be able to just turn on or off qcarbehaviour whenever it is needed.

I have a wish about My Trackables section. I have many trackables there and I want to transfer some of them from one to another. Let say 20 trackables. It is hard to remove and upload them again. I think, there should be a "Move" button that works for transferring trackables among projects.

The video playback sample app is good. It can play local video on layers. I have a wish on sample code of remote video playing on layer. And hope to change the video dynamically by the image scanned. (Maybe only keep one player and change the content url when other image is scanned).

Due to the fact that I cannot edit my previous feature request post without completely messing up the format (the infamous rich text format debacle), I have to make a new post every time I want to add something new. So once again, please fix the numerous forum bugs.

Edit11:
-Fix the grid on video image visual artifact bug with the image target demo.
-Access to all the recognized features in the entire camera image (corner detection).
-A combination between SLAM and marker detection can be made this way: If a marker is in view, the camera pose is known. If the camera is then translated, all other features in the camera image can be triangulated easily because an exact camera transform change between frames is available. The newly detected features with their solved 3d position can be used to track the camera when the marker is temporally lost. Any thoughts on this?

Edit12:
-Bug: If application is frozen using CameraDevice.Instance.Stop(), then multitasked to home, then back into program: Freeze is automatically unfrozen for video, but tracking is still frozen.

#1 wish: can create marker/image tracker offline.

if offline is too much.. at least publish the API. Smile

Hello everyone,

Incase you did not get the e-mail blast. You may be interested in the Vuforia play mode to be released later in the fall.

Just wondering if it is possible to use single image as pattern and then we can detect simlar images using Vufroia SDK?

To elaborate more, lets say I have Trackable Data of Apple Image, now if i point the camera to any apple then it should detect that?

I guess we can add this in coming releases.

1. I second all wishes made by elecman, especially re SLAM implementation.

2. Would like to see image matching & tracking, which could be used for images with small number of features but still very distinct visual representations, e.g. traffic signs, logos.

I'd like that once the image is tracked, use the gyroscope/ accelerometer in order to continue to track the scene even if the trackable is out of view.

Vuforia is amazing. I'd like to be able to access the TMS through my code uploading images to it and downloading the resultant .dat. I mean to keep the service online as it's now, but to be accessible through code because the UI of manulally uploading the images impose restrictions on the apps. It doesnot make sense for an AR app to force the components of the reality, i wish the apps based on vuforia could be fexible in "which imagetragets that could be detected".

Thnx alot
