Abstract: A process of video capture, segmentation, tracking, and mapping to obtain position and time data for motion analysis. The moving object is captured in video in a series of frames at a known frame rate. The moving object is isolated from all other data in a frame and the position of the moving object is determined relative to stationary reference elements in the frame. However, the video captures a physical, three-dimensional space, in a two-dimensional image, causing distortions. This method associates all points in the quadrilateral with a rectangle defined by sides in real, physical space using a vanishing point algorithm. The preferred vanishing point algorithm maps a physical space to a quadrilateral defined by two sides that intersect at a first vanishing point, and two other sides that intersect at a second vanishing point. Single-point or three-point perspective may also be employed.
