The invention discloses a target prediction method based on a laser cleaning foreign matter device. The method comprises the following steps that aiming at a high-voltage cable, kinematic modeling iscarried out through dynamic analysis, and a motion track with unfixed parameters is obtained; and the motion track is projected into a camera plane coordinate system to obtain a corresponding track inthe camera plane coordinate system. Model parameters are worked out through foreign matter position data acquired by data acquisition, the track of foreign matter winding points at the current momentin the camera plane is fitted, the tracked objects are subjected to prediction and tracking in the time of image recognition, and the time delay of image recognition is compensated. The method can improve the real-time performance of tracking in a working process of the laser cleaning foreign matter device, so that tracking is more accurate and timely, a cutting point of a laser is more accurate,and the cutting efficiency of device is effectively improved.
