Abstract

The invention relates to the technical field of medical instruments, and discloses a medical rehabilitation underwater gait analysis system and method based on skeleton calculation. The system comprises a plurality of underwater cameras used for shooting moving images of human bodies in water; the light source equipment is mounted underwater and is used for irradiating the reflective marker ball on the human body; the reflective marker ball is used for being mounted on a preset mark point of a human body so as to reflect light; the image processing module is used for acquiring an underwater human body motion image shot by the underwater camera and carrying out image distortion correction and mark point position detection; and the skeleton resolving module is used for carrying out skeleton model construction and skeleton resolving based on the position change of the mark points so as to carry out gait analysis. The method has the advantage of being capable of achieving efficient and accurate motion capture and gait analysis in a complex underwater environment.
