- The deformation of the location of structural systems is an important step to predict the performance of the system under different conditions. In bridges, the plastic deformations generally occur over a long-span beam after years of service. To improve the detection accuracy and stability of bridge deformation, in this paper, we proposed a new deformation inspecting framework. The total procedure of our algorithm may be concluded as the following three aspects. Firstly, because of the beams of bridges are very long, to improve the resolution of images, we divided the acquiring of the bridge beam image into a sequential images. Secondly, the sequential images are proposed with character point extraction, image stitching, image segmentation, and the calculation of the bridge deformation. Finally, the calculated deformation was compared with the experimental results. According to the experiments on the real bridges and the simulating model, the results indicated that our algorithm may improve the detection accurate to a large extent. At the same time, the proposed algorithm is more flexible than the former proposed algorithms.
