Abstract

The invention is suitable for the technical field of noise source positioning, and provides a noise source positioning method, device and system based on sound and images, and the method comprises the steps: obtaining sound signals collected at different positions; judging whether a loud noise position exists or not according to the sound intensity of the sound signal; if the loud noise position exists, controlling a camera to carry out image acquisition towards the loud noise position; and performing artificial intelligence algorithm identification on the image, judging whether personnel aggregation exists in the image, and if yes, determining that the position of personnel aggregation is the position of the noise source. According to the method, the device and the system, a sound and image combination mode is adopted, after the loud noise position is recognized according to the sound signal collected by the noise sensor, image collection and recognition are performed on the loud noise position through the camera, whether the noise source exists or not is further determined, and therefore the accuracy of noise source determination and positioning is further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of noise source location, and in particular relates to a noise source location method, device and system based on sound and images. Background technique [0002] At present, many people's concept of pollution is limited to nature and the environment, but noise has a tendency to disturb the natural rhythm of life, so it is also a kind of pollution. Noise pollution not only brings inconvenience to life and work, but also brings irreversible damage to physical and mental health in the long-term. Short-term noise makes people feel tired and irritable. People who have been affected by noise for a long time will experience symptoms such as dizziness, headache, neurasthenia, indigestion, high blood pressure and cardiovascular disease. [0003] In order to effectively control the noise, the noise source location analysis must be carried out first. However, in the existing methods, the noise sensor is mainly used ...
