The invention provides a rail transit-related direct-current magnetic bias electrified detection data synchronization method, which comprises the following steps: A, acquiring rail transit direct-current magnetic bias detection-related data, which comprise video information and magnetic bias current data stored in a background; B, preprocessing the bias current data stored in the background and obtained in the step A to obtain a divided bias current set; C, according to the video information obtained in the step A, extracting two groups of video feature quantities with forward bias current and reverse bias current from the video information; and D, matching the video feature quantity extracted in the step C with the divided bias current set obtained by preprocessing in the step B, and calculating the time difference between the video feature quantity and the bias current set to realize synchronization of detection data. The rail transit direct-current magnetic bias detection data synchronization method provid
