Analysis method, device and storage medium of accompanying relationship

Abstract

The invention discloses an analysis method of accompanying relationship. The analysis method of accompanying relationship includes the following steps: obtaining the first time-space similarity between each identity feature, and judging the identity feature according to the first time-space similarity. Whether there is a time-space similarity between the identity features, the identity features include at least one of IC card number, MAC address, IMSI code and face image information; when there is a time-space similarity between the identity features, obtain the spatiotemporal trajectory point pairs of spatiotemporal similarity; when the number of spatiotemporal trajectory point pairs is less than or equal to a preset threshold, it is determined that the individual corresponding to the identity feature is in an accompanying relationship. The invention also discloses an analysis device and a storage medium accompanying the relationship. The invention can use data of multiple identity characteristics when mining accompanying relationships, greatly increases the amount of data, and has more accurate mining results.

Description

technical field [0001] The present invention relates to the field of information technology, and in particular, to a method, a device and a storage medium for analyzing an adjoint relationship. Background technique [0002] Mining the accompanying relationship between travelers can provide important references for traffic route design, crime prevention, etc., and is one of the current research focuses in the field of intelligent transportation. [0003] At present, mining the accompanying relationship between travelers through big data is generally based on bus card data. Each bus card corresponds to a traveler. By collecting the historical time points and corresponding locations of bus cards, the spatiotemporal similarity between bus cards is calculated. Thereby, the accompanying relationship between bus cards can be mined. However, since the historical spatiotemporal data of single identity information is generally less, the accuracy of the mined adjoint relationship is l...

Problems solved by technology

[0005] The main purpose of the present invention is to provide a companion relationship analysis method, device and storage medium, aiming to solve the problem that the mining of travel personnel companion relationship is only based on the spatio-temporal data of the same identity feature, the amount of data is small, and the accuracy of the mining results is low. low technical issues
