Research on urban renewal based on semantic segmentation and spatial syntax: taking Wuyishan City as an example

Since the last century, China's urbanization has developed rapidly, but due to the rapid development, many problems such as unreasonable urban internal space planning have come along with it. Wuyishan City, which belongs to the Nanping area, just needs to make necessary and planned reconstruction of the city interior that is no longer suitable for its social life. Based on this, based on the semantic segmentation and space syntax theory of street view map, this paper quantitatively analyzes the internal space and existing problems of the city, and describes the spatial characteristics based on the measured values, and puts forward auxiliary planning suggestions, and these suggestions have been recognized by the project team of Tongji Planning Institute, providing them with some help, which proves that the study of semantic segmentation and space syntax is of great help to urban renewal.
