Image/laser ranging integrated system for monitoring airfield runway foreign matters

Abstract

The invention provides an image / laser ranging integrated system for monitoring airfield runway foreign matters. According to the characteristic that a connect camera can give out image pixel distances, the system gives out a judgment condition for judging whether the weather is normal or windy, or rainy or snowy, according to weather classification, a detection method for the airfield runway foreign matters when the weather is normal, a solution method for foreign matter detection mistakes caused by light flotage appearing nearby the upside of an airfield runway on windy days, an image affinity projection filtering method for snowy and rainy days and an infrared intensifying method for the haze weather are given out, and the airfield runway foreign matters can be effectively, reliably and automatically monitored on line.

Description

technical field [0001] The invention relates to the problem of on-line monitoring of foreign objects on the runways of civil aviation, military aviation and general aviation airports. It particularly relates to an image / laser ranging airport runway foreign body monitoring integrated system, which belongs to the field of information technology. Background technique [0002] Foreign objects on the pavement of an airport can easily be sucked into the engine, causing the engine to fail. Debris will also accumulate in the mechanical device, affecting the normal operation of the landing gear, flaps and other equipment. Due to the aircraft's huge engine suction and extremely fast take-off and landing speed, even small foreign objects on the runway will cause serious hidden dangers. According to conservative estimates, Every year, the global loss caused by foreign object (FOD) on the airport runway is at least 3 billion to 4 billion US dollars, and the indirect loss is at least ...

Problems solved by technology

[0005] In order to overcome the technical defect that the existing system cannot effectively and reliably automatically monitor foreign objects on the airport runway, the present invention proposes an integrated image / laser ranging airport runway foreign object monitoring system, which can provide the pixel distance of the image according to the connect camera Features, the judgment conditions for determining whether the weather is normal or strong wind, rain or snow are given, and according to the weather classification, the detection method of foreign objects on the airport runway when the weather is normal, and the quality that will appear near the airport runway when there is strong wind are given. The solution to foreign object detection errors caused by light floating objects, the image affine projection filtering method in snowy and rainy weather, and the infrared enhancement method in foggy weather have realized effective and reliable automatic online monitoring of foreign objects on airport runways
