Problems solved by technology
There are many kinds of activities between people in a single place, and the space of people's activities is not single and uncertain, so it becomes more cumbersome and repetitive to analyze the number of people gathered in a single activity in a single place, and even for some special activities in a single place There are very few people gathered, which has a great impact on the follow-up analysis

Embodiment Construction
[0033] Below according to the attached Figure 1 to Figure 4 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions and characteristics of the present invention can be better understood.
[0034] see Figure 1 to Figure 4 , a method for clustering and dividing regions based on the physical location density of a place in an embodiment of the present invention, comprising the steps of:
[0035] S1: Collect location information of multiple target places in a target area;
[0036] Draw and obtain a scatter distribution map of each target site according to the location information;
[0037] S2: Set the value of a minimum number of places in the target area as k;
[0038] S3: Draw a distance map to obtain the target site according to the minimum number of sites and location information, and determine the minimum radius of an area;
[0039] Wherein, the S3 step further includes the steps:
[0040] S31: Calculate the Euclide...

The invention provides a method for dividing regions based on place physical position density clustering. The method comprises the following steps: S1, collecting position information of a plurality of target places in a target region; s2, setting a numerical value of a minimum place number of the target area as k; s3, drawing a distance map of the target place according to the minimum place number and the position information, and determining the minimum radius of an area; and S4, clustering the position information according to the minimum radius of the region and the minimum place number toobtain a clustering result. According to the method for clustering and dividing the regions based on the physical location density of the places, a plurality of single places with close distances aregathered together to form a large region, so that subsequent analysis is facilitated; by gathering single places, the gathering place range is expanded, and a larger search range is provided for analyzing some special activities.
Description
technical field [0001] The invention relates to the field of ships, in particular to a method for clustering and dividing regions based on the physical location density of places. Background technique [0002] Places include public places such as entertainment, catering, and accommodation, as well as other private places, and a place where there are dramas is a place. There are many kinds of activities between people in a single place, and the space of people's activities is not single and uncertain, so it becomes more cumbersome and repetitive to analyze the number of people gathered in a single activity in a single place, and even for some special activities in a single place There are very few people gathered, which has a great impact on the follow-up analysis. Therefore, in order to analyze the number of people gathered in some special activities more conveniently and concisely, a method for clustering and dividing regions based on the physical location density of the v...
