Combining Ground Plane and Image Targets

By SoluisDev on Wed, 12/20/2017 - 10:59

Hi there,

 

Is it possible to combine Image Targets and Ground Plane, so that we can place content in a specific location (using the Image Target) but then continue to maintain the Augmentation by utilising the Ground Plane technology? Say for example I want to augment an entire room, so we have a tracker at the door to set up the relativity of the space, without requiring user input, but then want to allow them to walk through the space without the need of further trackers (but using the ground instead). 

+1 for this.

This is not my understanding of "ARKit Integration into vuforia". I need a real world anchor, from where the device tracking always starts the same.

There is a problem for ARkit, it doesn't know its absolute position. So the first idea to fix it, is of course using marker(s) as absolute position reference. I tried to do something like that with Vuforia. i add a ground plane. i add a image target.

I achieved something with this TrackableEventHandler and a setup as in the screenshot.

First of all you have to initialize the ground by tapping on the screen, then you can recognize the image target.

@strasza, that's the two big ones I need.  Not sure how you'lI implement but I think we'll need midair anchor versions of both methods for things like posters and signs, ie it shouldn't work just on horizontal image targets.

Also interested in this functionality. I would like to be able to detect my image or book and if it is sitting on a table be able to make my models explore the surrounding areas.

I am also interested in both functionalities.

Could we get clarification if this is a bug or a feature request?

Based on how Fusion was advertised I understood that the functionality should be available right now?

What i have noticed is that when you put a big object like a house and draw a tall cube in the center, where spawns, when you move to the center, which is the image target and the cube you should reach always the cube where is the target image but that is not what happens, the distances are not a

Hi guys!
I hope here you will find the answer to your questions.
And sorry for my English!

The task is such, to connect the ImageTarget and GroundPlaneStage or MidAirStage.

Instruction:

1. Set on scene ImageTarget

@rsultangareev Hi, thanks for the post I tired it but it doesn't; work very well I have a image target which has the mid air stage as a child and that has the augmented gameobject as its chid but it doesn't work well I also changed it so there is a image target with the midair stage as its child

ImageTargetTrackable works well, however orientation is not as expected. How to handle orientation if I use the same source code for detection of object targets?

@rsultangareev I tried a similar approach and the positioning is way off.

Please see the image attached.

My aim is to allow several people within a room to experience an AR scene thats positioned and rotated in the exact same place for everyone.

Hi Vuforia,

Do we have an update on this?

The final solution ended up doing a ScreenRay cast of the ImageTracker's screen position with the Ground Stage plane.  I did not make the ImageTracker a child of the ground stage.

Hi scott_a_ashton, I'm very thanks for your sharing. I tried to get Image Target screen point by WorldToScreenPoint, but the value was pretty strange when I put Image Target and Ground Plane Stage on the same layer..

Hey scott_a_ashton,
Would you mind explaining a little bit more of how you got this working?
We are helping a professor try to do pretty much the same thing you are.
If you could even provide a small example or snippet I would be super grateful!
