Abstract

The invention discloses a terminal strip wiring image checking method based on dynamic vision, a storage medium and equipment, and the method comprises the steps: obtaining a field video stream of a terminal strip, extracting a key frame from the field video stream through employing a video frame dynamic analysis technology, carrying out the preprocessing of the extracted key frame, and generating a standard frame; setting prompt words of the visual large model, inputting all the standard frames into the visual large model, and obtaining a checking result of terminal strip wiring; searching whether an inconsistent checking result exists in the checking results of the same terminal strip wiring, and if not, taking the checking result of the terminal strip wiring as a final checking result; and otherwise, performing secondary checking on the inconsistent terminal strip wiring by using the visual large model, and updating the checking result of the terminal strip wiring by using the secondary checking result to obtain the final checking result. According to the invention, through a video frame dynamic analysis and verification mechanism, the accuracy of terminal strip wiring image verification can be improved.
