Abstract

The invention belongs to the technical field of noise maps and provides a noise map drawing method and device. The method include acquiring environmental noises, including noise values, time information and location information, uploaded by terminals; when the terminals upload images corresponding to the environmental noises, detecting whether the images are valid or not; when the image is valid and is shot indoors, recognizing the noise as indoor environmental noise; when no image is provided, the image is invalid or the image is valid and is shot outdoors, recognizing the noise as outdoor environmental noise; drawing a noise map according to the indoor environmental noises and outdoor environmental noises. By the aid of the method, the noise map drawing accuracy is improved, and the reliability of the noise map is improved.

Description

technical field

[0001] The invention belongs to the technical field of noise maps, in particular to a noise map drawing method and device. Background technique

[0002] With the increase of population and the increase of various equipment, there are more and more sources of noise pollution. Users need a noise map that can show the current noise in various places to guide their travel and other daily arrangements, just like the real-time road conditions Figure 1 Sample. At the same time, the improvement of hardware storage capacity and computing power, the development of cloud technology and big data technology, and the development of various new data mining machine learning and even deep mining technologies provide the basis for the realization of location-related noise mapping.

[0003] However, existing noise map drawing methods cannot distinguish between indoor ambient noise and outdoor ambient noise, which is not conducive to improving the accuracy of noise map drawing...
