Abstract

The present application relates to a sound source localization method, device and storage medium, and belongs to the field of computer technology. coordinate value; obtain the coordinate conversion relationship and correction matrix; use the coordinate conversion relationship and correction matrix to convert the first coordinate value to the second coordinate system to obtain the second coordinate value, so as to trigger the image acquisition component to collect the sound source corresponding to the second coordinate value It can solve the problem that the monitoring result of the converted whistle position is not accurate enough due to the inaccuracy of the coordinate transformation matrix when the coordinate position of the whistle is converted through the coordinate transformation matrix; because the calibration matrix can correct the coordinate transformation relationship for coordinate transformation Therefore, the accuracy of determining the position of the sound source can be improved.

Description

technical field [0001] The present application relates to a sound source localization method, device and storage medium, belonging to the technical field of computers. Background technique [0002] The honking of vehicles in urban areas will seriously disturb the residents, so most areas stipulate that vehicles are prohibited from honking in urban areas. In order to ensure the monitoring of illegal whistle, it is necessary to locate the whistle position, and transmit the whistle position to the license plate capture device. The license plate capture device captures and stores the license plate number of the vehicle whistle in violation of regulations. [0003] In a typical sound source localization method, when the whistle monitoring device and the license plate capture device are installed, the distance and deflection angle of the whistle monitoring device relative to the license plate capture device are obtained; the distance and deflection angle are used to construct a co...
