Multi-camera personnel positioning, tracking and displaying method based on human skeleton detection

The invention discloses a multi-camera personnel positioning tracking display method based on human skeleton detection. The method comprises the steps: calibrating a plurality of cameras in a target region, obtaining an internal parameter and an external parameter of each camera, and storing the internal parameters and the external parameters; calculating the foreground of two frames of images acquired by each camera before and after to obtain a foreground change value, and when the foreground change value of each camera is greater than a preset foreground threshold, determining that the cameras are synchronous; identifying a target person image acquired by the camera through the mathematical model and extracting human skeleton points after determining that the camera is synchronized, mapping the human skeleton points through internal parameters and external parameters of the camera to obtain space rays, and matching the space rays through a matching algorithm; after matching is completed, according to the po
