How to find main (left) camera transform from world anchor? (Enterprise API) From CameraFrameProvider() I can get a frame sample which has an "extrinsics" parameter. How is it defined? Relative to what point/anchor?

Answered by Vision Pro Engineer in 812836022

The camera extrinsic transform is relative to the DeviceAnchor.

Does it make sense that the extrinsic translation is just 2 centimetres from the device anchor?

translation = 0.024845406, -0.02110077, -0.057464134

From measuring the camera location on VisionPro, it's definitely more than 2 cm from the "center" of VisionPro

The DeviceAnchor origin is not at the "center" of Vision Pro.
