I'am currently struggling to get extrinsic matrices while recording depth video using TrueDepth camera in AVFoundation.
Here's how i get my extrinsics inside depthDataOutput function:
if let calibrationData = depthData.cameraCalibrationData{
let extrinsicMatrix = calibrationData.extrinsicMatrix
}
When i print the extrinsicMatrix i only get identity matrix. Is there a way to get actual extrinsics without ARKit or this method (.extrinsicMatrix) just does not work at all?
