Unmanned aerial vehicle bridge bottom detection system

Abstract

The invention discloses an unmanned aerial vehicle bridge bottom detection system, and the system comprises an unmanned aerial vehicle collection module which is used for collecting bridge bottom images at multiple angles; a positioning module which is used for acquiring position information of the unmanned aerial vehicle in real time; a transmission module which is used for transmitting the acquired image and the position information of the unmanned aerial vehicle to a processor; and the processor which is used for processing the acquired image to obtain bridge bottom detection information. Compared with traditional detection, equipment and instruments developed by the project are simple and convenient, easy to install and operate, economical, reasonable and low in requirement for the measurement environment. Only simple calibration work needs to be carried out regularly, and the precision of a measurement result is high. Besides, in the system, various wireless sensor network technologies are adopted, so that data acquisition and transmission are more reliable, matched geographic information can be acquired by utilizing GPS equipment, and the GPS equipment can be combined with an electronic map to perform real-time data acquisition and display on bridge health.

Description

technical field [0001] The invention relates to the field of rapid inspection of bridges, in particular to an unmanned aerial vehicle bridge bottom detection system. Background technique [0002] At present, the conventional bridge safety inspection equipment is relatively simple, and the main inspection equipment includes artificial telescopes, remote photography, bridge inspection vehicles, and preset track video inspections. Almost all of these traditional detection methods have problems such as low efficiency, high cost, and certain safety hazards for testing personnel. For this reason, the development of UAVs for bridge safety inspections not only greatly improves the efficiency, but also ensures personal safety. [0003] UAV obstacle avoidance technology refers to when the UAV aircraft encounters obstacles during automatic flight, it can achieve the effect of flight safety through automatic early identification and effective avoidance of obstacles, which is one of the...
