[0077] In this embodiment, the region to be divided is explained as an example of a city. In practical applications, the region to be divided can be any national, provincial, municipal, or village-level map. Now, the present invention will be further explained in combination with specific application scenarios.

[0078] Regional POI (Point of Interest, point of interest) is a very important division index. Regional POI refers to points of interest in the region, such as restaurants, shopping malls, gymnasiums, schools, companies, and so on. Each POI contains at least four aspects of information: name, category, longitude, and latitude. POI information reflects the location semantics of the region, which is the meta-feature of the region, and the flow of people is attracted by POIs. Therefore, it is very important to understand the distribution of POIs in the region to calculate the flow of people in the region. Thiessen polygon (Voronoi polygon) is a method proposed by Dutch ...

Abstract

The embodiment of the invention provides a method and device for region division. The method comprises: a regional boundary of a to-be-divided region is obtained and a rectangular boundary of the to-be-divided region is calculated; location information of a transportation junction point in the to-be-divided region is obtained and a shortest-path polygon is drawn by using the transportation junction point as a discrete point; regional combination processing is carried out on the shortest-path polygon and the rectangular boundary of the to-be-divided region to obtain a preliminary regional division result; feature vector calculation parameters of interest points in the to-be-divided region are obtained and feature vectors of all interest points in all regions in the preliminary regional division result are calculated based on the feature vector calculation parameters; on the basis of the feature vectors of all interest points in all regions, regional similarity degrees between all regions and spatial adjacent regions are calculated; and according to the regional similarity degrees, regions in the preliminary regional division result are combined to generate a final regional divisionresult. According to the invention, with full consideration of characteristics of a road network and regional interest points, regional division becomes reasonable.

Description

technical field [0001] The present invention relates to the field of urban planning, in particular to an area division method and device. Background technique [0002] In recent years, with the rapid development of LBS (Location Based Service, location-based service) and GIS (Geographic Information System, geographic information system), urban area research has become more and more important in many fields, such as route planning, traffic Flow analysis, regional passenger flow analysis, regional population assessment, regional attributes, crowd movement, inter-regional relations, etc. Before performing these analyses, it is first necessary to divide the city into regions. [0003] In order to simplify the region division, the most commonly used method is the grid-based map segmentation method. This method divides the map into squares of fixed size, and analyzes the squares as regions directly. Although it is simple and convenient to implement, it is also difficult. There ar...
