Airfield runway foreign matter and crack recognizing system and detecting and recognizing method thereof

Abstract

The invention discloses an airfield runway foreign matter and crack recognizing system and a detecting and recognizing method thereof. The system comprises a camera, an FPGA processor and a DSP which are sequentially connected. The FPGA processor and the DSP are connected with a display module. The method includes the steps that S1, the camera collects a runway color image of an airfield runway pavement; S2, the FPGA processor reads the runway color image and converts the runway color image into a runway gray image for Sobel edge detection; S3, after edge detection, one path is stored in an SDRAM, and Hough conversion is conducted on the other path for removing graticule; S4, morphological filtering is conducted; S5, whether foreign matter and cracks exist in the runway image or not is detected, and if yes, a runway edge detection image is sent to the DSP to be processed; S6, the edge detection image is filled to form characteristics; S7, the characteristics are extracted and foreign matter or cracks are recognized.

Description

technical field [0001] The invention relates to the technical field of airport runway crack and foreign object detection and target intelligent identification system, in particular to an airport runway foreign object and crack identification system and a detection and identification method thereof. Background technique [0002] Airport runway maintenance is an important task. For airports, the integrity rate of the airport runway surface and whether there are foreign objects on the airport runway are very important indicators in flight safety. First of all, on the airport runway, it is the crack of the airport runway that poses a certain threat to the take-off and landing of the aircraft. The runway of the airport is affected by the take-off and landing of the aircraft, natural factors such as wind and sun, and the runway is damaged. When the crack is just formed, it is not a big threat to the safety of the aircraft, but if it cannot be found and maintained in time, the runw...

AI Technical Summary

Problems solved by technology

[0003] At present, for the detection of foreign objects and cracks on the pavement of the airport runway, it usually requires regular manual inspection by the staff, which is time-consuming, laborious and inefficient

A large number of foreign object and crack detection methods based on computer vision have been studied at home and abroad, but they are expensive in terms of cost and are not suitable for popularization

In terms of technology, many countries at home and abroad use scanning detection technology based on fixed high-frequency radar, while the development of high-frequency radar technology in my country is slow, and the technology cannot meet high application requirements, resulting in slow progress in domestic related research
