Referring to fig. 5, fig. 5 is a schematic flow chart of another exemplary noise dynamic visual monitoring method according to the present invention, which is executed by a noise monitoring device, and includes the following steps:
s201: and acquiring the position information of the user in the real environment and the noise data collected by the user at the position in real time.

S205, converting the first coordinate into a second coordinate according to a preset corresponding relation, wherein the second coordinate indicates the position information of the user avatar in the virtual geographic environment.
And S206, synchronizing the second coordinate corresponding to the user avatar with the first coordinate corresponding to the user, and synchronizing the noise data corresponding to the user at the second coordinate with the noise data collected by the user at the first coordinate.

The difference between the present embodiment and the dynamic visual noise monitoring method provided in the exemplary embodiment is that steps S202 to S206, and steps S201 and S207 to S208 refer to the relevant description of steps S101 and S103 to S104, which is not described herein again, and steps S202 to S206 are specifically as follows:
s202: and carrying out position registration on the position information of the user in the real environment.
In the embodiment of the application, the location information of the user in the real environment is acquired through the location system, but due to the influence of the network environment and the road condition, the location drift phenomenon often occurs in the location system, so that the location information needs to be subjected to location registration to ensure the accuracy of the location information.
S203: and removing abnormal data and redundant data and carrying out interpolation estimation on missing data on the position information of the user in the real environment and the noise data acquired by the user at the position.
In the embodiment of the application, after the position information of the user in the real environment and the noise data collected by the user at the position are obtained, the noise monitoring device performs quality control operation on the position information and the noise data, specifically, the quality control operation may be elimination of abnormal data and redundant data, interpolation estimation of missing data, or the like, or may also be reconstruction, data cleaning, or the like of the data, and the quality control operation may be combined at will to further ensure accuracy of the position information and the noise data.
S204: first coordinates are obtained, the first coordinates indicating position information of a user in a real environment.
The noise monitoring device obtains first coordinates indicating location information of a user in a real environment. In the embodiment of the application, the first coordinate comprises a longitude and latitude coordinate and an elevation value, and the position of the user can be accurately positioned through the first coordinate.
S205, converting the first coordinate into a second coordinate according to a preset corresponding relation, wherein the second coordinate indicates the position information of the user avatar in the virtual geographic environment.
The longitude and latitude coordinate system of the real environment is different according to different used positioning systems, and when a GPS positioning system is adopted to obtain the longitude and latitude coordinates, the corresponding coordinate system is WGS 84; when the longitude and latitude coordinates acquired by the GPS are actually applied to a certain area or city, the WGS84 needs to be converted into a local coordinate system, such as HK1980 in hong kong.
Moreover, because a set of coordinate systems exists in the virtual geographic environment, when the position synchronization is performed, the noise monitoring device needs to convert the first coordinate into a second coordinate according to a preset corresponding relationship, and the second coordinate indicates the position information of the customized avatar in the virtual geographic environment. Specifically, the noise monitoring device converts the longitude and latitude coordinates in the first coordinate to obtain the longitude and latitude coordinates in the second coordinate according to a preset corresponding relation, and the elevation value in the first coordinate is not changed and is directly set as the elevation value in the second coordinate.
The preset correspondence relationship may be a conversion relationship between a coordinate system of the virtual geographic environment and a WGS84 coordinate system, or may be a conversion relationship between a coordinate system of the virtual geographic environment and a local coordinate system. When the local coordinate system conversion is involved, the local coordinate system and the WGS84 coordinate system may be converted first, and then the WGS84 coordinate system and the coordinate system of the virtual geographic environment may be converted.
And S206, synchronizing the second coordinate corresponding to the user avatar with the first coordinate corresponding to the user, and synchronizing the noise data corresponding to the user at the second coordinate with the noise data collected by the user at the first coordinate.
The noise monitoring device synchronizes the second coordinates corresponding to the user avatar with the first coordinates corresponding to the user, and synchronizes noise data corresponding to the user at the second coordinates with noise data collected by the user at the first coordinates.
