Design of joint range of motion measurement based on Kinect

Range of motion is a common test item in clinical rehabilitation medicine, which can be used as an important evaluation index in the field of postoperative recovery and disability identification. At present, the goniometer is widely used to measure the range of motion of human joints in clinic. Although this method is simple, it is inefficient, wastes a lot of human resources, and the measurement results are subjective. In order to solve the disadvantages of traditional manual measurement, this paper proposes a new measurement method, which uses Microsoft’s latest generation Azure Kinect depth camera to measure human joint range of motion. According to 32 human bone joint points obtained by Azure Kinect bone tracking technology, an algorithm for calculating joint range of motion is designed.
