I am not sure if the
Air 2 sensors work the same way as the M2 or not but note that DJI uses at least 2 types of sensors.
The side sensors on the
Mavic 2, for example, are not stereoscopic, so they do not work in 'real time' like the others do, and they only work in tripod mode, point of interest, circle, helix, boomerang, timelapse and active track. They work by creating a depth map by comparing consecutive images, so they only work with slower consistent/predictable movement.
Just taking a quick look, it seems all the
Air 2 sensors are stereoscopic which is nice to see. No DJI drones allow you to use the sensors at maximum speed (sport mode) and one reason for this is because the attitude (pitch) change of the aircraft is too steep to allow the sensors to adequately see what is in front or behind you (they end up pointing too far up or down to do their job).
