Has the headset been confirmed to work in the dark? It would requires apple to have flood lights on the headset to light up the environment no that the cameras can see.
It has in front both lidar and truedepth camera - truedepth camera has IR flood flights and IR cameras but provide resolution of depthmap 640x480 at 30fps. Unfortunately raw IR camera video stream is not available for 3rd parties so you could only render this VGA depthmap heatmap style.
