Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0013] The so-called trajectory collision refers to the starting point and end point of the suspect vehicle. Assuming that the possible driving path of the suspect vehicle is known, find out a number of checkpoints that must pass through the path, and query the traffic information database of each checkpoint through association to find out the sequence of events in a reasonable time. The same vehicle that passes through these bayonets within range. That is to find a car according to the trajectory, and match a large number of actual vehicle trajectories through the analyzed virtual trajectory to find out the matching vehicle. At present, the actual monitoring conditions do not have the conditions to obtain the complete trajectory of the vehicle, but only use the monitoring information of multiple bayonets to form a discontinuous trajectory, also known as "multi...

Abstract

The invention relates to a suspected vehicle analysis method based on track collision, comprising the following steps of: a. obtaining a plurality of running paths of a suspected vehicle according to the starting point and the terminal point of the suspected vehicle; b. extracting corresponding bayonet information on each running path; c. calculating the appearing ratio of the vehicle on the corresponding running path; d. comparing the appearing ratio of the vehicle on the corresponding running path in the step c with the set ratio to obtain a first vehicle data set which is greater than the appearing ratio on the corresponding path; e. carrying out comparison detection according to the relevant information of the suspected vehicle and the first vehicle data set obtained in the step d, and obtaining a second vehicle data set; and f. comparing corresponding passing vehicle information pictures in vehicle information and bayonet information in the second vehicle data set with associated motor vehicle registration information boxes to obtain the suspected vehicle. The invention greatly shortens the process of searching the suspected vehicle and improves the identification accuracy.

Description

technical field [0001] The invention relates to a method for analyzing a suspected vehicle, in particular to a method for analyzing a suspected vehicle based on trajectory collision, and belongs to the technical field of intelligent transportation. Background technique [0002] In recent years, highway intelligent monitoring technology has developed rapidly. Local public security departments and transportation departments have installed and deployed a large number of highway intelligent monitoring equipment (referred to as checkpoints), gradually forming a networked motor vehicle monitoring pattern. An application environment is provided for the grid-based suspect vehicle analysis method. [0003] With the popularization of motor vehicles, car-related cases such as car theft, traffic hit-and-run, drug trafficking, and driving around to commit crimes have increased significantly. Some of them only have part of the number on the number plate (for example, in the case of a hit...
