A Survey on IMU-and-Vision-based Human Pose Estimation for Rehabilitation

With the rapid development of human pose estimation, the human-pose-estimation method applied in rehabilitation therapy has attracted more and more attention in today's aging society. Among them, inertial measurement units (IMU) and computer vision are two significant methods for human pose estimation. We mainly pay attention to the application of these two methods in the rehabilitation therapy field. In this paper, we first summarize the research status of IMU and computer vision in the field of rehabilitation therapy. Subsequently, we find that combining the two methods can produce better results. Finally, the main problems of the current research and possible development directions are identified.
