Model Target on iOS not working well

Unity Editor
November 22, 2022 - 12:10am #1

I'm trying to make my application work on iOS devices, but I noticed a problem.

Vuforia seems to detect the object, but can't place on it my augmentation. All of the 3D models are shown correctly and all the functionalities work, but there is "no 3D", I see the assets locked in 2D (anyway, camera can be moved, I mean, the augmentation is not anchored to the camera).

Do I miss something in the build phase? Which is the problem?

NB: I tested before on Android and everything goes well.

Model target not workin

Topic solved

Hello Vuforia team,

I loaded the Vuforia example.

If I use the standard example of the Mars Rover as the model target, it works and it shows the outline of the model.

When I load my own model I don't see any outlines. I just switches the generated model, with the model generator!

Why is that, see screenshots in the attachment.

Limitation in dimensions of real object

Unity Editor
September 25, 2022 - 2:00am #1

Respected People,

I would like to have some information regarding the limitations of Vuforia model tracking capabilities in HoloLens 2.

Questions:

1. What should be the minimum dimensions of the real object in all the directions (x,y,z) and the optimal range from which it should be tracked?

2. Can Vuforia track objects that are very small in dimensions, probably like a very small screw or a nut, if yes from what range is it possible?

Model Taget and AROcclusionManager

Unity Editor
September 8, 2022 - 6:34pm #1

There seems to be a case where the combination of Model Target and Human Occlusion (AROcclusionManager on ARFoundation) does not work well.

As shown in this attached video, the hand itself seems to be recognized, but it seems to fail to determine the depth map.

This seems to occur frequently, especially on the iPad.

Does anyone know how to solve this problem?

Note that when combined with Object Target (Vuforia 9.8), it works as expected.

Unity Editor

I updated MTG from 10.8 to 10.9.3.  I made new training database in it.  It trained successfully.  But once i click export button, only a zip file will be exported and without *.unitypackage.   And i can't unzip it. So How can i import it into Unity?
