Video-based airplane entry-departure parking lot automatic detection method

Abstract

The invention relates to a video-based airplane entry-departure parking lot automatic detection method. A video image of a monitoring area covering an airplane shutdown parking lot area is obtained, a motion object is identified and tracked, characteristic points of an image in a detection area are extracted and tracked in a matching manner, when the number of characteristic points meeting airplane entry or departure direction requirements in a certain number of continuous frames of the video image accords with a required quantity, a judgment about official entry or departure is further made, and when displacement of a characteristic point set is smaller than certain pixels and the motion object does not enter but continuously departs from an airplane shutdown parking lot area, it is determined that an airplane officially parks in place; and when the displacement of the characteristic point set is smaller than or equal to certain pixels and the motion object does not depart from but continuously enters the airplane shutdown parking lot area, it is determined that the airplane officially departs, wherein the detection area is a set are opposite to the airplane shutdown parking lot area on the video image. The method provided by the invention can realize round-the-clock intelligent detection of accurate arrival time of airplane flight and is quite high in detection accuracy.

Description

technical field [0001] The invention relates to an automatic detection method for aircraft entering and leaving a berth based on video processing and analysis, and belongs to the fields of digital image processing and intelligent video monitoring. Background technique [0002] my country's aircraft flights take off on time with the new standard of removing chocks. Off block is a common technical term in the global civil aviation industry. Like the car on the ground, in order to avoid the car from slipping, when the car is parked in the parking space, a baffle is placed in front of the car. After the aircraft removes the chocks, it can start the engine and taxi. Compared with the original statistical standard that the flight is on time when the cabin door is closed, the new standard means that not only the airlines have made preparations for all the passengers to board, but also the airport has made the luggage loading on the plane, and the aviation fuel has been refueled. ...
