Embodiment 1

[0033] This embodiment provides a method for identifying urban functional areas combined with POI data, which is applied to electronic equipment, such as figure 1 shown, including the following steps:

[0034] S101. Acquire target area information, and acquire a remote sensing image of the target area according to the target area information.

[0035] The target area information may be input manually, or complete information may be obtained from the Internet based on part of the information input manually. The target area information includes the name of the target area and the coordinates of the target area, etc., the name of the target area is the name of the administrative region, such as Beijing, Hebei Province, and the coordinates of the target area are the position of the target area in the geographic coordinate system, and the geographic coordinates The coordinate system can be one of WGS-84 coordinate system, Beijing 54, and Xi'an 80, and different coordinate systems ...

Embodiment 2

[0052] This embodiment provides a method for identifying urban functional areas combined with POI data, which is applied to electronic equipment, such as figure 2 shown, including the following steps:

[0053] S201. Obtain target area information, acquire road network information of the target area according to the target area information, and obtain block information of the target area according to the road network information.

[0054] The target area information may be input manually, or complete information may be obtained from the Internet based on part of the information input manually. The target area information includes the area name and its coordinates, etc. The area name is the name of the administrative region, such as Beijing, Hebei Province, etc. The target area coordinates are the position of the target area in geographic coordinates, and the geographic coordinate system can be The WGS-84 coordinate system, Beijing 54, Xi'an 80, etc., can be converted between ...

Abstract

The invention provides a method for identifying urban functional areas combined with POI data, storage media and electronic equipment, wherein the method for identifying urban functional areas includes: acquiring high-resolution remote sensing images of target areas according to acquired target area information; acquiring high-resolution remote sensing images based on target area information According to the urban road network information of the target area, the block information of the target area is obtained according to the urban road network information; the high-resolution remote sensing image is divided according to the block information to obtain the block remote sensing image; the block remote sensing image is divided by the selective search algorithm to obtain a small scene image ; use the scene recognition model to identify small scene images, and obtain the scene recognition results of the small scene images; integrate the scene recognition results and POI data of each block, and use the hidden Dirichlet allocation model to carry out topic modeling to mine the latent semantic features of blocks, Get the urban function recognition results of each block. The above method can improve the recognition accuracy of urban functional areas.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a method for recognizing urban functional areas combined with POI data, a storage medium and electronic equipment. Background technique [0002] Urban functional area is a geographical space that can realize the spatial aggregation of relevant social resources and effectively exert a certain urban function. It reflects the characteristics of the city in a concentrated manner and is a form of modern urban development. In existing studies, scholars mainly divide urban functional space into residential areas, commercial areas, science and education areas, industrial areas, public service areas, leisure areas, and transportation areas. Accurate identification of urban functional areas can not only promote the development of urban planning theory, but also provide optimization suggestions for the urban spatial distribution pattern and form a more scientific and reasonable urban spatia...
