The Research of Platform for Bridge Visual Inspection Based on Quadrotor Aircraft

摘要

Table view examination is one of the important means and basic steps of the bridge structure. It founds up less than 0.2 mm small cracks in up to hundreds of meters or tens of kilometers long buildings. It must be close to the observed. However, the modern bridge structure is diverse, the surrounding environment is complex, and the appearance of detection is difficult to achieve. In this paper, the problem of bridge appearance detection is discussed, and the application prospect of the four rotors unmanned aerial vehicle is discussed. At the same time, this paper also discuss about how to improve the four rotor unmanned aerial vehicle to be applied to the preliminary exploration of the appearance of the bridge structure, and preliminary indoor environmental testing, testing its feasibility. As it can be seen from the test results, the four rotors unmanned aerial vehicle can be applied in the appearance of the bridge detection. Finally, the paper analyzes and summarizes the challenges of the four rotors unmanned aerial vehicle in the bridge appearance detection.
