The Mavic 2 Pro and Mavic 2 Zoom are equipped with Forward, Backward, Downward and Lateral Vision Systems including Upward and Downward Infrared Sensing Systems. These all provide omnidirectional obstacle detection, providing lighting conditions are adequate.

The main components of the Forward, Backward and Downward Vision Systems are six camera sensors located on the nose, rear end and underside of the Mavic 2 quadcopter.

The lateral Vision System are 2 cameras with one camera on each side of the Mavic 2 quadcopter.

The main components of the Upward and Downward Infrared Sensing Systems are 2 x 3D infrared modules located on the top and underside of the Mavic 2 quadcopter.

The Downward Vision System and Infrared Sensing System helps the Mavic 2 maintain its current position and hover in place very precisely. The Vision and Infrared Sensing system allow the Mavic 2 to fly indoors or in other areas where a GPS signal is unavailable.

Excellent info

Thank you for the information. Do any DJI quadcopter use LiDAR for obstacle avoidance?

I do not think so as of now DJI only uses vision detection technology as it is far lighter and does not require higher processing units which maybe heavier on these drones and requiring more redesigning. Lidar is far more accurate than vision detection but for faster obstacle recognition the vision technology is faster as it does not need to wait for light rays to reflect back on the sensor
