Embodiment 1

[0027] figure 1 It is an implementation flowchart of the noise map drawing method provided by the embodiment of the present invention, which is described in detail as follows:

[0028] In step S101, the environmental noise uploaded by the terminal is obtained, and the environmental noise includes noise value, time information and location information;

[0029] Wherein, the time information represents the time information of the environmental noise record, which may be specific to minutes, that is, year, month, day, hour, minute, or specific to seconds, that is, year, month, day, hour, minute, and second.

[0030] It should be noted that this embodiment does not limit the time unit of the time information.

[0031] Location information includes, but is not limited to, latitude and longitude and geographic location.

[0032] It should be noted that the server may be any existing server, including but not limited to a physical server and a virtual server. Wherein, the virtual...

Embodiment 2

[0045] figure 2 It is the implementation flowchart of the noise map drawing method S102 provided by the embodiment of the present invention, and is described in detail as follows:

[0046] In step S201, it is detected whether the picture carries the generation mark of the rear camera;

[0047] In step S202, when the picture carries the generation mark of the rear camera, it is judged that the photo is a valid photo, and when the picture does not carry the generation mark of the rear camera, it is judged that the photo is an invalid photo .

[0048] When the picture carries the generation mark of the rear camera, it means that the picture is generated by calling the rear camera of the terminal, and it is judged that the photo is a valid photo;

[0049] When the picture does not carry the generation mark of the rear camera, it means that the picture is generated by calling the rear camera of the terminal, and it is determined that the picture is invalid.

[0050] In the embo...

Embodiment 3

[0052] An environmental noise mining model is configured, and the environmental noise mining model includes at least one of an environmental noise clustering model, a noise decibel mean value model, and a noise weighted value model;

[0053] Wherein, the environmental noise clustering model is:

[0054] Δ = Σ i , m ( Σ j γ i | θ ij - θ mj | ∂ ) ∂

[0055] Among them, Δ is the similarity, Indicates the number of openings, θ ij Indicat...

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...
