AR camera from texture

Unity Editor
June 30, 2022 - 10:07am #1

Hi all,

I'm working on an android development board, trying get a vuforia-unity project working.

I had a problem with the camera and the only way to get a feed is though a texture.

Is there a way to connect a texture to feed the AR camera?

 

Thank you

Topic solved

Now I use unity to create an arcamera and a cube. When I run on a mobile phone that supports arcore, the cube is in the world coordinates, but when I run on a mobile phone that does not support arcore, the cube is displayed in the middle of the screen. How can I put the cube in the world coordinates on a non arcore mobile phone

The picture on the left is displayed on non arcore phones, and the picture on the right is the effect on arcore enabled phones

Vuforia Marker Based Tracking Issue

Unity Editor
June 28, 2022 - 11:03am #1

Overview: I am developing a Unity project for HoloLens 2 that uses Vuforia marker based tracking to track various objects. I have encountered an issue with both standard tracking and extended tracking. When I look at my image target, all tracked child objects appear and are in the correct relative positions. However, when I shift my own perspective while wearing the HoloLens, the tracked objects shift positionally to some extent when I need them to stay in the same position regardless of the perspective. For example, I turn my head to the right and the objects move to the right.

Cylinder Target vanishes unless Mask out behaviour is disabled

So I am using a CylinderTarget and it works great - I can see the rocket fine... when Mask Out Behaviour is disabled.  If I leave it enabled it will replace all materials on the rocket with DepthMask and it will be invisible.

Any ideas why this happens? thanks

Integrating Vuforia With Open CV for unity On the Magic Leap One Device

Unity Editor
June 27, 2022 - 6:39am #1

Hello,

I am trying to develop an application that does real time object detection on Magic Leap One Device. I have tested the Vuforia's Model Targets on the device and was able to detect some objects with the help of the guide views. However, I am interested in integrating custom models trained using OpenCV with Vuforia in Unity. Is there any way to implement this?

Your quick response is highly appreciated.

Object position not set when OnTargetFound event is fired

Unity Editor
June 23, 2022 - 12:29am #1

Hello!

I am currently working on a project where we need to use the position of a tracked object only once when it is tracked. To achieve this we tried using the OnTargetFound event. But it seems like on the frame where OnTargetFound is called, the position of the tracked object is not yet updated. If we add a .25 second delay to updating the position it looks like its working most of the time.
