Problems solved by technology

As for the beam floor, the conventional detection methods and methods have limitations, the operation is very difficult, and there are inspection blind spots
Among them, local blind areas can be inspected manually, but the efficiency is low, the difficulty is high, and the risk factor is high. The use of drones for auxiliary detection will solve these problems to a large extent.

Abstract

The invention discloses a bridge detection unmanned aerial vehicle path planning method, which belongs to the technical field of unmanned aerial vehicle path planning. The method comprises the steps that using the method of flying along the edge is used to acquire the contour information of a bridge; grid-based environment model construction is carried out; target area decomposition is carried out; adjacent sub-area convergence is carried out; sub-area optimal path traversal is carried out; and all standing traversal of the bridge bottom is carried out. According to the invention, the algorithm has the advantages of low repetition rate, high coverage rate, no detection blind zone theoretically; the algorithm is simple and easy to implement; and the algorithm can better complete the task of all standing traversal path planning of an unmanned aerial vehicle on the bottom of the bridge.

Description

technical field [0001] The invention belongs to the technical field of UAV path planning, and in particular relates to a method for UAV path planning for bridge detection. Background technique [0002] With the rapid development of today's social economy, more and more high-risk workers will be replaced by artificial intelligence. In recent years, with the continuous development of aerial photography technology, drone applications have penetrated more into all walks of life. Unmanned aerial vehicles can be divided into many categories. Among them, unmanned multi-rotor aircraft can be used in highway bridge inspections, line inspections and other fields due to their simple structure and relatively low price. [0003] The management and maintenance department usually inspects the bridge on a regular basis, mostly using traditional inspection methods, relying on the naked eye or auxiliary tools (such as bridge inspection vehicles, binoculars, etc.) and other diseases. As for...
