Zusammenfassung:The invention relates to a dual-mode abnormal skeleton data correction method based on spatio-temporal information and optical flow extraction, and the method comprises the following steps: S1, obtaining and preprocessing a human body motion video data set, obtaining a training data set, and training a human body posture estimator based on computer vision based on the training data set; s2, generating an initial posture of each video frame for an input video sequence according to the trained human body posture estimator, and performing anomaly detection on the initial postures; s3, respectively searching a latest trusted preorder frame and a latest trusted postorder frame from the front and the back of the abnormal frame, and extracting optical flow information of a continuous sequence between the latest trusted preorder frame and the latest trusted postorder frame; and S4, according to the obtained optical flow information, forward optical flow correction and reverse forward optical flow correction are respe
