The invention discloses a three-dimensional information perception system for highway road surface diseases, including: a sensor system integrating a laser, a 3D camera, a Beidou positioning system, a right-of-way camera, and a distance measuring instrument; High-speed data acquisition and state detection system of model and control panel software; road surface three-dimensional data storage system integrating point cloud data storage structure, Beidou data storage mechanism, right-of-way camera data storage structure, and preset data storage structure. The beneficial effect of the present invention is that it can effectively reduce the labor intensity caused by manual detection, as well as the problems of high subjectivity and low missed detection rate, and at the same time, it can solve the problem that two-dimensional road surface disease detection is sensitive to factors such as tire marks, shadows and uneven illumination. And the problem of low detection rate of road surface disease caused by the inability to obtain the depth information of road surface disease, provides a good basic guarantee for road inspection and maintenance.
Description
technical field [0001] The patent of the present invention relates to the field of highway pavement disease detection system, in particular to a three-dimensional information perception system for highway pavement disease. Background technique [0002] At present, manual detection and road detection vehicle detection based on two-dimensional images are mostly used in the detection of highway pavement defects. The result of high detection rate and low recognition rate; road detection vehicle detection based on two-dimensional images scans the road surface into two-dimensional image data, and the scanned road surface images are usually manually inspected, marked and classified by professional technicians , the existing detection vehicles can only obtain two-dimensional information of road surface diseases, that is, shape and size, but cannot obtain the depth information of road surface diseases. This makes the road disease information unable to be fully perceived, thus unable...
