[0034] The implementation process of the present invention will be described in further detail below.
[0035] The present invention maintains a method for anonymizing cross-road network locations with constant statistical characteristics, comprising the following steps:
[0036] Step A. Extract the road network to divide the target area to form a road network area: According to the distribution of roads in the target area, extract the road network to realize the division of the target area, and obtain the number of location points contained in the road network area and the centroid of the road network area location features.
[0037] Let the latitude and longitude of the lower left corner and upper right corner of the target area be respectively (X MIN , Y MIN ), (X MAX , Y MAX ), according to the actual application requirements (for example: the scale is 1:1000), intercept the map picture of the target area on the open API in this range, and convert it to the HSV color s...
