Airport bird information obtaining method based on panoramic and precise image tracking system

Abstract

The invention provides an airport bird information obtaining method based on a panoramic image monitoring and precise image tracking system. A semispherical polyhedron of the panoramic image monitoring system is densely provided with visible light and infrared CCD camera arrays for covering low-altitude panorama. The panoramic image monitoring system automatically monitors whether there is a bird in a big scene range or not: transmits a signal to start the precise image tracking system to track the bird if there is the bird in the big scene range. The precise image tracking system employs a big-width and high-frame-rate CCD and multiple high-transformation-ratio variable and controllable automatic lenses, achieves the precise tracking monitoring in a range of a plurality of square kilometers, enables the resolution to reach the precision which allows a feature spot of the bird to be recognized, and obtains the morphological characteristics of the bird: body length, body shape, wing shape, tail shape and feather color, and also obtains the bird behavior and posture comprising the flying path, flying posture, wing flapping frequency and amplitude and landing posture, and the detail information of foraging habits.

Description

technical field [0001] The invention relates to ornithology, acoustics, and image tracking systems, in particular to an airport bird information acquisition method for panoramic image monitoring and precise image tracking systems, and belongs to the fields of ornithology and information technology. Background technique [0002] The route of joint monitoring and recording of bird flight and foraging habits and other characteristics can not only provide advanced monitoring technology means and equipment for the research of rare birds and important species, and obtain basic data for the protection of fragile ecosystems of birds, but also can predict , Reduce or even avoid the occurrence of bird collision incidents. [0003] With the rapid development of the aviation industry, the incidents of bird strikes at airports have gradually increased, which not only brought huge economic losses to the aviation industry, but also endangered the lives of pilots and passengers, and also ca...

Problems solved by technology

[0007] In order to solve the technical problems of image recording the flight path, flight posture, wing flapping frequency and amplitude, landing posture, foraging habits and detailed differences of birds, the present invention provides a system based on panoramic image monitoring and precise image tracking The method of acquiring bird information at the airport. The panoramic image monitoring system is densely arranged on the hemispherical polyhedron with visible and infrared CCD camera arrays covering the low-altitude panorama. The panoramic image monitoring system automatically monitors whether there are bird activities in a large scene range. For activities, the signal is used to start the precise image tracking system to track the birds. The precise image tracking and monitoring system uses large-format, high-frame-rate CCD and multi-variable controllable automatic lenses with high zoom ratio to achieve precise tracking and monitoring within a range of several square kilometers. , so that the resolution reaches the accuracy of distinguishing the characteristic spots of birds, and the morphological characteristics of bird body length, body shape, wing shape, tail shape, and feather color are obtained, including flight route, flight attitude, frequency and amplitude of wing flapping, and landing attitude. The detailed information of bird behavior posture and foraging habits in the system solves the difficulty of automatically obtaining the bird's flight route, flight posture, frequency and amplitude of wing flapping, landing posture, foraging habits and bird detailed difference information technical issues
