The present invention belongs to the technical field of particle motion recognition, and in particular to a method for simultaneously tracking the position and orientation angle of moving particles based on image recognition. This method is applicable to the tracking of active rotors. The image information of moving particles is collected by an image acquisition device. The motion trajectory is determined by tracking the position change of significant color markers on the moving particles. Then, two selected symmetric clusters are used on the color markers, and the angle between the vector determined by the geometric centers of the two clusters and a fixed direction is used as the orientation angle of the moving particle. The orientation angles at multiple time points are taken within a time period, and after removing mutations, linear fitting, and monotonic processing, the relationship between the orientation angle and time is obtained, thereby simultaneously determining the position and orientation angle of the moving particle. The present invention has developed a new method based on image recognition technology, providing a practical algorithm for studying the collective behavior of active rotors and a new method for analyzing images and videos of particle models that can perform translational, rotational, and combined motions.
