Abstract

The invention belongs to the technical field of highway slope patrol, and in particular relates to a UAV-based highway slope patrol path optimization method. The UAV-based highway slope patrol path optimization method comprises the steps of: (1), controlling the UAV shooting quality, so that the best shooting angle is obtained; (2), classifying shot objects, and determining a shooting mode according to the classification condition; (3), shooting an object needing to be shot through an UAV, troubleshooting according to a shot picture, and extracting problem suspicion points of a slope in the picture; (4), calculating the distance between the problem suspicion points, and constructing an adjacent matrix of the problem suspicion points; and (5), taking the adjacent matrix constructed in the step (4) as input of a simulated annealing algorithm, and obtaining the shortest path of the UAV traversal problem suspicion point by calculation. According to the UAV-based highway slope patrol path optimization method in the invention, the highway slope is patrolled through the UAV; furthermore, the reasonable patrol path can be planned; and the problem that the artificial patrol workload is highin the prior art can be solved.

Description

technical field

[0001] The invention belongs to the technical field of highway slope inspection, and in particular relates to a path optimization method for highway slope inspection based on an unmanned aerial vehicle. Background technique

[0002] With the rapid development of computers and communications, UAV aerial photography systems have also entered the stage of practical application in various industries from the initial research stage in the military field, and are widely used in forest fire prevention, resource detection, search and rescue, agricultural inspection, aerial photography, etc. aspect. The inspection application of UAVs at home and abroad has covered many fields such as electric power, petroleum, agriculture, and communications. Inspection is both the focus and difficulty of road maintenance inspection. At present, the manual inspection is mainly used to inspect the slope, but the workload of manual inspection is heavy, and the inspection of the slope ...
