FIELD: sound.SUBSTANCE: invention relates to acoustics, particularly to birds detection facilities. Device contains distributed system of cameras and microphones mounted on peripheral stations, and connected to them central processor for determining coordinates of object images from them. At that, acoustic narrow-directed microphones have same direction and located together with video surveillance cameras on rotary devices with remote control. Cameras and microphones are oriented in two planes and receive sound and image in real time, transmitting birds voice and their image by wire or radio channel to central station, where after sound and image processing, recognition object and calculating its coordinates from central station tracking command is sent to rotary device. Device also has system for scaring of birds, activated upon detection thereof. Identification of birds is performed by software, which is developed with possibility to calculate direction by means of optical bearing. Calculation of elevation and its position is performed by triangulation.EFFECT: technical result is provision of automatic recognition of coordinates of birds.1 cl, 5 dwg |
