| titleOfInvention | Speed measuring method and device for mobile vehicle |
| abstract | The invention discloses a speed measuring method for a mobile vehicle, which comprises the following steps: acquiring a three-dimensional coordinate (0,0, H) of the camera C; acquiring video frame images of a moving vehicle J at a time t0 when the moving vehicle J enters the shooting range of the camera and a time t1 when the moving vehicle J leaves the shooting range of the camera, and carrying out continuous focusing shooting on the moving vehicle J in a time period from t0 to t 1; acquiring hardware parameters of the camera C, optical parameters of the camera C at the time t0, optical parameters of the camera C at the time t1 and video frame image parameters; calculating the coordinate position and the running distance G of the mobile vehicle J at the time t0 and the time t 1; according to the travel distance G of the moving vehicle J in the time period from t0 to t1, the average vehicle speed V of the moving vehicle J in the time period is obtained. The intelligent traffic monitoring system does not need to additionally install other speed measuring equipment, can be directly deployed in the existing security monitoring network, enlarges the range of intelligent traffic management, and has the advantage of wide application. |
