The invention provides a bridge crack detection and visualization method, apparatus and device, and a readable storage medium. The bridge crack detection and visualization method comprises the steps of obtaining a plurality of bridge local images shot by an unmanned aerial vehicle; based on the plurality of bridge local images, establishing a three-dimensional live-action model of the bridge and determining position coordinates of a region of interest corresponding to a bridge crack; based on the position coordinates, obtaining a region-of-interest image shot by the unmanned aerial vehicle; based on the image of the region of interest, quantized data of the bridge crack are obtained, and the quantized data comprise length and width information of the bridge crack; fitting the three-dimensional real scene model with a bridge model of a BIM platform according to an actual position to obtain a BIM model with real scene fitting; and displaying the quantized data on the bridge crack corresponding to the quantized data on the BIM model. According to the invention, the bridge crack detection efficiency and precision can be effectively improved, and the visual display of the crack data is realized.
Description
technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge crack detection and visualization method, device, equipment and readable storage medium. Background technique [0002] In the process of using, the bridge will be aged and damaged due to the long-term external pressure and tension. For example, the prefabricated slabs, prefabricated piers, and poured roundabouts of steel plate composite girder bridges generally have typical defects such as transverse cracks, vertical cracks, and radial cracks. Usually, engineering personnel are required to conduct a comprehensive monitoring of the bridge to avoid sudden accidents caused by bridge damage. [0003] At present, the main means of crack detection of bridges is still based on manual visual inspection. This kind of method has the following problems: first, the reliability is low. Since the results of manual visual inspection depend on the subjective experience of eng...
