Abstract

The invention discloses a target vehicle tracking snapshotting method and device, and the method comprises the steps: obtaining a current frame image from a video recorded by a photographing device at a preset time interval after a transmitted target vehicle tracking snapshotting instruction is received, and extracting a target vehicle image from the obtained frame image; judging whether the target vehicle image in the frame image meets the preset requirements or not: storing the frame image if the target vehicle image in the frame image meets the preset requirements, or else adjusting the optical parameters of the photographing device, so as to enable the target vehicle image in the recorded video of the photographing device to clearly reflect the information of a target vehicle. According to the invention, the method and device achieve the capturing of the image from the recorded video at the preset time interval, achieve the adjustment of the optical parameters of the photographing device according to the obtained current frame image, so as to enable the target vehicle image in the recorded video of the photographing device to clearly reflect the information of the target vehicle, and to obtain the image which can reflect the information of the target vehicle clearly from the recorded video.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for tracking and capturing a target vehicle. Background technique [0002] With the full popularity of automobiles, social problems such as urban traffic congestion and frequent highway traffic accidents have become increasingly prominent, and most of these problems occur due to drivers' traffic violations. [0003] At present, the traffic management department monitors and captures traffic violations by installing cameras on road sections, but there are blind spots at some small intersections or roads with fewer vehicles; in addition, based on the advancement of modern technology, the navigation system on general vehicles will Prompt the driver on which road sections will have snapshots, which makes many drivers feel lucky, so running a red light, going the wrong way, reversing at will, changing lanes forcibly, turning around on double soli...
