Panoramic and accurate image/spherical crown variable excitation amplitude modulation frequency modulation bird sound detecting system

Abstract

The invention proposes a panoramic and accurate image / spherical crown variable excitation amplitude modulation frequency modulation bird sound one-body detecting system. The panoramic image monitoring system comprises visible light and infrared light CCD photographing arrays that are densely lined on a spherical crown polyhedron and covers the low altitude panorama. The panoramic image monitoring system can automatically monitor the birds' activities in a large field scope, and if there are birds' activities, a signal is given to start the image precisely tracking system to track the birds so as to obtain the morphological characteristics of the birds such as their lengths, the swing types, the tail types and the feathers, and the detailed information about the behavior attitudes and the hunting habits of the birds including their flying routes, their flying attitudes, their swing vibration frequencies and amplitudes. Through the arrangement of a plurality of double-excitation sound transmitters at different positions on the spherical crown surface and through the co-excitation manner featuring coil winding on the soft electromagnetic core first before imposing electricity as well as based on the signal intensity of the birds' sounds, the buzzing positions of different birds can be obtained.

Description

Technical field [0001] The invention relates to an ornithology, acoustics, and image tracking system, in particular to an integrated detection system for bird recognition with panoramic image / precision image / spherical crown variable excitation amplitude modulation and frequency modulation bird sound, belonging to the field of ornithology and information technology. Background technique [0002] Routes that jointly monitor and record the characteristics of bird flight and foraging habits can not only provide advanced monitoring techniques and equipment for the study of rare birds and important species, and obtain basic data for protecting the fragile ecosystem of birds, but also predictable , Reduce or even avoid the occurrence of bird strikes with aircraft. [0003] With the rapid development of the aviation industry, the number of incidents of bird collisions with airplanes at airports has gradually increased, which not only brings huge economic losses to the aviation industry, bu...

Problems solved by technology

[0007] In order to solve the technical problems of acquiring birds’ chirping sounds, image recording of birds’ flight routes, flight posture, frequency and amplitude of wing flapping, landing posture, foraging habits and differences in bird details, the present invention provides panoramic and precise images / Spherical crown variable excitation AMFM FM bird song integrated detection system, panoramic image monitoring system is densely arranged visible and infrared light CCD camera arrays on the spherical crown polyhedron to cover low-altitude panorama, panoramic image monitoring system automatically monitors in a large scene range Whether there is bird activity, if there is bird activity, it will send a signal to start the image precise tracking system to track the birds. The precise image tracking monitoring system adopts large format, high frame rate CCD and multi-variable controllable automatic lens with high zoom ratio , to achieve accurate tracking and monitoring within a range of several square kilometers, so that the resolution can reach the accuracy of distinguishing the characteristic spots of birds, and obtain the morphological characteristics of birds' body length, body shape, wing shape, tail shape, and feather color, including flight routes, flight attitudes, Detailed information on bird behavior including wing flapping frequency and amplitude, landing posture, and foraging habits;

[0009] The invention solves the technical problem that it is difficult to automatically acquire birds' singing, birds' flight routes, flight postures, frequency and amplitude of wing flapping, landing postures, foraging habits, and bird detailed difference information
