Abstract

The disclosure provides a whistle sound detection device, a whistle sound identification and positioning method and system, including: at least three support plates, multiple sound detectors, control chips and more than two cameras, wherein each of the A plurality of sound detectors are arranged in the support plate, and each sound detector is electrically connected with the control chip; the included angle between two adjacent support plates is the same. The camera captures pictures in different directions. Using 4 cameras, it is possible to capture pictures in 4 directions of the intersection. It is used to solve the problems of narrow coverage and low sound positioning accuracy in the existing horn-honking capture technology.

Description

technical field [0001] The present disclosure relates to the field of information technology, and in particular, to a whistle sound detection device, a whistle sound recognition and positioning method, and a system. Background technique [0002] With the increase of the number of motor vehicles in cities, the whistle of motor vehicles has become the main source of environmental noise in urban areas. The traffic control department has set up no-sounding areas in specific areas, but it is difficult to obtain evidence and punish illegal whistle vehicles due to difficulties in obtaining evidence. As a result, the no-singing zone is useless. [0003] In the prior art, the images of vehicles are generally taken by cameras installed at intersections, the license plate information in the pictures is extracted, and finally the sound source location terminal and the license plate information are combined to determine the vehicle honking, and the sampling evidence is saved. However, w...
