The invention provides a bridge support health state detection method and terminal equipment, and the method comprises the steps: controlling a target camera to work in a long-focus shooting mode, obtaining a target image corresponding to a bridge support from the target camera, extracting line data in all directions in the target image, carrying out the matching calculation of the line data in all directions, and determining an actual displacement sequence of the bridge support in each direction; and if the actual displacement sequence of the bridge support in each direction does not meet thepreset condition, controlling the target camera to work in a short-focus shooting mode, obtaining a panoramic image corresponding to the bridge support from the target camera, inputting the panoramicimage into a preset convolutional neural network, and determining the apparent disease type of the bridge support. The bridge support health state detection method and the terminal equipment providedby the invention are lower in detection cost and higher in detection efficiency.
Description
technical field [0001] The invention belongs to the technical field of bridge structure health detection, and more specifically relates to a bridge support health state detection method and terminal equipment. Background technique [0002] As a large-scale structure on the traffic line, how to ensure that the bridge maintains a good health during the operation period is of great significance to ensure the safe and smooth transportation of the line. Considering that the bridge bearing is an important component of the bridge, once the structure is damaged, it will inevitably affect the stress state of the bridge structure and even traffic safety. Therefore, the condition detection of the bridge bearing is an indispensable link in the bridge construction and maintenance work. [0003] In the process of bridge construction and operation, the change of bridge bearing displacement is one of the important indicators reflecting the health status of bridge bearings. How to detect the...
