Visual patrol inspection system and method for monitoring airfield runway pavement

Abstract

The invention discloses a visual patrol inspection system for monitoring an airfield runway pavement. The visual patrol inspection system is installed on an airfield runway pavementpatrol inspection vehicle. The visual patrol inspection system comprises a display, a processor, a linear array camera, an encoder and a satellite positioning system. The visual patrol inspection method comprises the steps that: an encoder converts angular displacement of a coded disc into a periodic electric signal, then converts the periodic electric signal into a counting pulse signal and sends the counting pulse signal to a processor, the processor receives the counting pulse signal and controls a line-scan digital camera to shoot an image once, generate image information and send the image information to the processor, and the processor receives the image information and displays the image information through the display; and an operator carries out re-judgment according to the displayed image and annotation. According to the visual patrol inspection system and the visual patrol inspection method, the defects in the prior art can be overcome, the judgment accuracy and efficiency of the pavement damage and the foreign matter are effectively improved, and the problems of low precision and misjudgment of detection depending on a camera or radar equipment at present and the problem of low time efficiency of pure manual inspection are solved.

Description

technical field [0001] The invention relates to the field of airport runway detection, in particular to a visual inspection system and method for monitoring airport runway surfaces. Background technique [0002] At this stage, the detection of airport pavement is mainly aimed at pavement damage and foreign objects. The existence of pavement damage and foreign objects will cause damage to the engine and tires of the aircraft, which is likely to cause safety accidents. Manual inspection by traditional means is inefficient and prone to omissions; in recent years, millimeter-wave radar, lidar and cameras have been used for inspection at home and abroad, but there are some defects, and cameras are easily affected by light and background conditions , The radar is greatly affected by the material and color, and the accuracy is difficult to guarantee under different road surfaces and environments, and the price is relatively high.
