Three-dimensional image-based defect recognition method, device and electronic equipment

Abstract

Embodiments of the present disclosure provide a method, device, and electronic device for defect recognition based on three-dimensional images, which belong to the technical field of data processing. The method includes: acquiring a set of three-dimensional point cloud data captured by an unmanned aerial vehicle; The size of the three-dimensional target object of the target object described by the data set, the projection contour length sequence of the n target objects in the horizontal direction is determined to form a first eigenvector; based on the eigenvalues ​​of the n axial contour feature matrices, a second feature matrix is ​​formed. eigenvector; multiplying the first eigenvector and the second eigenvector as a horizontal vector and a vertical vector, respectively, to obtain a feature matrix of the target object in the three-dimensional point cloud data set; based on the result of the matching calculation, determine Types of target objects and corresponding defects in the 3D point cloud data set. Through the processing solution of the present disclosure, the invading foreign objects can be effectively detected and monitored.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a defect recognition method, device and electronic equipment based on a three-dimensional image. Background technique [0002] With the rapid development of China's economy and the acceleration of urbanization, railway transportation has become an important means of transportation, which is closely related to the daily travel of urban residents, commuters, tourists and business people. [0003] Rail foreign object detection refers to the measures to check the rail area for foreign objects in order to ensure the safety of trains. According to the relevant regulations on the safe running of trains in our country, in the railway line safety protection zone and its adjacent areas, there must be no foreign objects that endanger the normal running of the train within the railway limits stipulated by the state, so as not to cause the driver to see the foreign object...

AI Technical Summary

Problems solved by technology

According to the relevant regulations on the safe running of trains in our country, in the railway line safety protection zone and its adjacent areas, there must be no foreign objects that endanger the normal running of the train within the railway limits stipulated by the state, so as not to cause the driver to see the foreign objects at a relatively short distance. Braking treatment, but the braking is not timely, the braking distance is too long and the collision with foreign objects causes property damage and safety accidents
