Multi-track collision analysis method based on behavior track library

Abstract

The invention discloses a multi-track collision analysis method based on a behavior track library. The multi-track collision analysis method comprises the steps of setting the target, the time and theanalysis parameters; filtering the track data of the target; aggregating the data to obtain a target activity time set; counting the equipment distance information and associating the equipment distance information with the target activity time set; counting all the target collection devices and removing the weight; filtering the track data of the target follower; aggregating the data and outputting the data to the next link; carrying out data association on the data and the track data of the target; judging and outputting the data meeting track crossing conditions; aggregating the data; judging whether the target meets various track collision target conditions or not; and outputting all multi-track collision targets meeting the conditions. According to the method, the multi-track collision targets of the target person can be accurately analyzed, and the analysis result of the multi-track collision targets in the behavior track library can be rapidly obtained.

Description

technical field [0001] The invention relates to the field of security and information technology, in particular to a method for analyzing collisions of various trajectories based on a behavioral trajectory library. Background technique [0002] At present, a variety of monitoring equipment in the security system will collect a large amount of behavior trajectory data, including: face, MAC, IMSI and IMEI; and the collection equipment in the security system can only identify the target information that enters its detection range, and cannot judge From which direction the monitoring target enters the detection range of the device, and the distance between the device and the monitoring target cannot be obtained, so the precise geographical location of the target cannot be obtained. Usually the system uses the geographical location of the acquisition device itself as the location of the detection target, and the acquisition equipment is divided into fixed acquisition equipment an...
