Airfield runway foreign object recognition image processing device and method

Abstract

The invention provides an airfield runway foreign object recognition image processing device and method. The device comprises a high-definition webcam, an FPGA connected with the high-definition webcam and a console connected with the FPGA. The position information of a foreign object in an airfield runway is acquired through a radar, and according to the position information of the foreign object, the optical axis of the high-definition webcam arranged outside the airfield runway turns to the area of the foreign object; the high-definition webcam carries out video acquisition on the area of the foreign object, a processing module calculates the gray mean value of the received current frame of image, and according to the gray mean value, whether a laser lighting unit needs to be turned onis judged; besides, according to the position information of the foreign object, the area of the foreign object on the image is marked; and the image is restored through an atmospheric turbulence image restoration algorithm. Thus, clear restoration of degraded images under moderate and weak atmospheric turbulences can be realized, and the environmental adaptability of the airport runway foreign object detection system can be improved.

Description

technical field [0001] The invention relates to an image processing device and method for identifying foreign objects on an airport runway, which adopts GPU+FPGA technology and uses a foreign object target recognition algorithm adapted to the use environment of the runway to complete the high-precision detection of foreign objects under different weather conditions Detection, and clear restoration of degraded images under moderate and weak atmospheric turbulence, improving the environmental adaptability of the airport runway foreign object detection system. Background technique [0002] Typical FOD targets are metal parts (screws, nuts, washers, nails, and fuses, etc.), machine tools, flying objects (personal items, pens, pencils, buttons, etc.), concrete asphalt chips, rubber chips, plastics, and moving objects. plants etc. At present, domestic airport runway inspections mainly rely on pavement inspectors to complete, and the runways will be closed during pavement inspecti...

AI Technical Summary

Problems solved by technology

At present, the runway inspection of domestic airports mainly depends on the pavement inspectors to complete, and the runway will be closed during the pavement inspection, which greatly reduces the flight capacity
