The invention relates to a high-motion table tennis trajectory tracking method, which comprises the following steps of: performing
motion blur correction on an original table tennis competition video, reducing
motion blur, and enabling the edge and the texture of a table tennis to be clearer; then super-resolution reconstruction
processing is carried out, the pixels of the table tennis balls in the frame images are increased, and the omission ratio is reduced when the improved YOLOv7
network model is adopted to carry out multi-scale
small target detection on the frame images after super-resolution reconstruction subsequently; next, an improved DeepSORT
algorithm is adopted to track the bounding box video
frame sequence detected in the second step to generate continuous two-dimensional coordinates, tracking position errors are reduced, then a three-dimensional track is obtained through
monocular depth
estimation and table plane constraint reconstruction, the whole process is subjected to
assembly line design, error accumulation of traditional staged
processing is avoided, and the tracking accuracy is improved. Four difficulties of small targets,
motion blur, shielding and complex backgrounds are jointly solved, and the average success rate gt of the whole process is obtained; 90%.
