Long, medium and short series focal length lens combined visual sensing array and method thereof

Abstract

The invention relates to a long, medium and short series focal length lens combined visual sensing array, which drives a large-range visual sensing array arranged on a rotary holder to carry out full-coverage scanning inspection in a flight airspace by controlling the holder to rotate, and collects bird condition image information, the collected image information is transmitted to the image processing module to be processed, bird flocks are positioned and tracked, the types of birds are analyzed, and a bird repelling strategy is formulated. The invention further relates to a control method forcombining the visual sensing array based on the long, medium and short series focal length lenses by utilizing the visual sensing array. By adopting the long, medium and short series focal length lens combined visual sensing array and the method thereof, the long, medium and short focal length lenses are combined into the visual sensing array, amplified clear and complete images can be obtained for bird flocks with different distances, automatic aiming tracking and recognition can be realized for moving birds, and analysis data and strategies are provided for automatic bird repelling.

Description

technical field [0001] The invention relates to the field of airport airspace prevention, in particular to the field of airport airspace bird strike prevention, and specifically refers to a long, medium and short series focal length lens combination visual sensor array and a bird repelling method for airport bird repelling. Background technique [0002] Bird strikes are a significant hazard to aviation. With the rapid development of science and technology in recent years, the volume, carrying capacity, and flight speed of aircraft have increased rapidly, making birds unable to alert and avoid moving aircraft, being sucked into or crashed into aircraft, and the low-altitude area near the airport is the aircraft In the cross range between the flight altitude and the flight altitude of birds, the aircraft is more prone to bird collision accidents during take-off and landing. Therefore, it is necessary to conduct full-coverage scanning and inspection of the airspace of the airp...

Problems solved by technology

In the usual bird strike prevention strategy in the airspace of the airport, the motorized pan / tilt is used to drive the single focal length camera to rotate to collect the image information of the bird flock. The resulting image is large and narrow, and the coverage area is small. Birds are easy to fly out of the field of view, and fast-flying birds cannot be effectively tracked.

In the actual scene, birds may exist at close range and long distance at the same time. Using a single focal length camera is inefficient for collection, and it is easy to miss the best time to repel birds. Therefore, different focal lengths are required for image collection at different distances. Camera array for airport airspace bird situation image collection
