Using the front Truedepth camera of a fixed-positioned iphone13, I capture the depth map of a static scene through AR Kit and then rectify (undistorted) them using the inverseLensDistortionLookupTable. Without changing the position of camera and the scene, every time that I launch the session, the rendered depth maps are randomly different. Given that I roughly know the ground truth, depending on the launched session, the depth maps are sometimes reasonably accurate and sometimes severely distorted non-linearly (up to 10cm bias), i.e. one side of the depth frame is still accurate other side is off. Is there any solution? or if there is any metadata to correct or rectify the depth maps later on?
