Working vehicle measurement method and system based on video

The invention discloses a video-based operation vehicle measurement method and system, and the method comprises the steps: calling a virtual scene graph mapped by a to-be-measured operation region in response to a received to-be-measured operation region monitoring request sent by a user side; when the to-be-measured operation area enters the measurement state, acquiring a real-time video stream of the to-be-measured operation area; and after the working vehicle in the real-time video stream is automatically calibrated, the working vehicle is automatically mapped to the virtual scene graph so as to measure the real-time working data of the working vehicle. The virtual scene graph is established for the operation area, and the position of the operation vehicle in the virtual scene graph is updated in real time based on the video stream, so that the measurement of the operation vehicle in the virtual scene graph is realized, the accuracy of the measurement data of the operation vehicle in the operation process
