This invention discloses a time-series-based method for detecting the landing performance of a standing long jump. The method decomposes the long jump motion and generates scatter plots for each decomposed motion based on the time series.

It can handle more landing situations, has greater versatility, is simple to calculate, has a fast processing speed, and high accuracy. Furthermore, the long jump image is processed before calculation, segmenting the human body and background, minimizing interference from the background during the calculation of the segmented image.
