Ultrasonic tracking system

An ultrasonic tracking system is a 3D tracking system that uses ultrasonic sound. It may do multilateration. It may use the Kabsch algorithm to do point-set registration.

It may be used, for example, in an AR glasses system to track the position and orientation of the glasses.

It needs a line of sight (auditory sight), which is a line of unimpeded travel between source and sensor.

Ivan Sutherland's report on the ultrasonic positioning system used with his 3D display did not mention any use of the Kabsch algorithm.^[1]
