Suspect vehicle inspection and control method and system

Abstract

The invention provides a suspect vehicle inspection and control method and system. The method comprises real-time acquiring a video stream and snap-shooting a vehicle image; subjecting the snap-shot image and a suspect vehicle sample image to color contrast to determine color similarity, and if the color similarity exceeds a set color similarity threshold, going to the next step; subjecting the snap-shot image and the suspect vehicle sample image to auxiliary characteristic contrast, to determine auxiliary characteristic similarity, the auxiliary characteristics including at least one of texture characteristics and shape characteristics; and comprehensively judging, and if the auxiliary characteristic similarity is larger than a set threshold, determining the comprehensive similarity by the auxiliary characteristic similarity or allowing the comprehensive similarity to depend on the auxiliary characteristic similarity. The vehicle image snap-shooting can be carried out by virtual coil triggering. Template match based on color can also be adopted to extract the auxiliary characteristics from a match region of the snap-shot image to be contrasted with the suspect vehicle sample image. The invention can realize rapid, efficient and accurate inspection and control effects, and save manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method and system for checking and controlling a suspected vehicle. Background technique [0002] With the rapid development of national road traffic construction and the popularization of motor vehicles, criminal and public security cases related to roads and motor vehicles are increasing year by year, especially the incidents of hit and run, theft of motor vehicles, and vehicle smuggling through the intercity highway network. It is becoming more and more rampant, which not only poses a great threat to social security, but also destroys the political situation of stability and unity. Therefore, it has attracted the attention of relevant state ministries and commissions to establish a cross-departmental and cross-regional comprehensive application system for motor vehicle monitoring. It is an inevitable trend in the construction and development of public security information...

Problems solved by technology

However, in the process of actual use, suspect vehicles generally avoid inspection and control by blocking or replacing license plates, which leads to little practical effect of the inspection and control system.
