The invention discloses an unmanned aerial vehicle bridge crack inspection system and method based on multi-sensor fusion. A positioning module is used for acquiring the position information of an unmanned aerial vehicle, an inertial navigation module is used for acquiring the state information of the unmanned aerial vehicle, and a radar module is used for acquiring the obstacle information. An information fusion module is connected with the positioning module, the inertial navigation module and the radar module and is used for fusing the received information, and a central control module receives the fused information and generates an obstacle avoidance and path planning strategy; a crack information acquisition module is used for acquiring the crack information and sending the crack information to an edge calculation module, and the edge calculation module processes, calculates and analyzes the crack information and sends an analysis result to a terminal through a data transmission module. Through the edge calculation module and the crack information acquisition module, the intelligent collection and detection of cracks are realized, and the real-time identification of the cracks and the quantitative analysis and monitoring of the crack width and length information are realized.
Description
technical field [0001] The invention relates to the technical field of bridge crack inspection, and more specifically relates to a multi-sensor fusion-based UAV bridge crack inspection system and method. Background technique [0002] At present, in the traditional manual inspection of bridge cracks, generally with the help of auxiliary equipment such as bridge inspection brackets and special inspection vehicles, together with tools such as small crack width gauges, steel rulers, and cameras, the distribution characteristics of cracks, including length and width, are manually observed and measured at close range. and other information. However, manual detection is greatly affected by the environment and harsh conditions, and also has disadvantages such as high cost, high risk, low accuracy, and low efficiency, which can no longer meet the growing needs. For a better and more effective bridge inspection, a UAV bridge crack inspection system based on multi-sensor fusion is pro...
