The idea that the camera is fixed to the human body

Recently, a foreigner asked me questions. Later, he recommended me to read the questions.ArticleIt was used to track the movements of the camera. I suddenly thought that if I fixed the camera to the human body, I would use EKF to track the motion direction and speed of the feature points, this set of things can be used to track human movements. Although it requires so many 11 cameras, the calculation is huge, but it is an interesting idea.
