Example Embodiment
[0075] The method for detecting the dynamic load distribution of vehicles on the deck of a cable-bearing bridge of the present invention, such as Figure 1 to Figure 15 As shown, a dynamic weighing device is installed at the entrance of each lane of a cable-bearing bridge to obtain vehicle weight information, and a camera is installed on the pylon to obtain images of traffic flow on the bridge deck. The camera's shooting range can cover the entire bridge deck; Perform perspective correction processing on the surface image to obtain an image of normal vehicle size; after obtaining the perspective corrected image, use the histogram matching method (histogram equalization method) to enhance the image; use the method based on edge information to detect whether there is a moving target Pass; use dynamic template matching method to track the trajectory of the vehicle based on the passing of the vehicle; through the capture and recognition of specific landmarks on the bridge deck, the ...
