Abstract

The invention discloses a device and a method for detecting and tracking vehicles crossing and pressing the yellow line and for capturing vehicle information. The device comprises a camera mounting frame at the middle section of the to-be-monitored road, a tracking PTZ and an electric motor thereof, and a camera which is used for collecting and capturing images and arranged at the PTZ and is controllable in focusing. The invention is characterized in that the device also comprises an image collecting card, an input / output card and a data processor; wherein, the image collecting card is connected between the camera and a data processor and used for sending the collected image information to the data processor; the input / output card is connected between the tracking PTZ and the data processor and used for controlling the tracking PTZ; and the data processor is used for analyzing and processing videos and controlling the tracking PTZ and the camera. The invention realizes the detectionof the moving vehicles which cross and press the yellow line under a dynamic background, effectively tracks the moving vehicles which cross and press the yellow line and captures the details of the color, model and the licenses of the vehicles in a large monitoring field coverage.

Description

technical field [0001] The invention relates to a vision-based vehicle detection tracking and vehicle information capture device and method for crossing and crossing yellow lines, specifically used for real-time dynamic tracking of moving vehicles crossing and crossing yellow lines; obtaining information about crossing and crossing yellow lines in monitoring videos Clear images of moving vehicles, so as to obtain detailed information such as the color, model and license plate of vehicles that cross or press the yellow line. Background technique [0002] Computer vision technology is a technology that acquires an image of an object by an image sensor, and a computer analyzes the image and controls the image sensor to complete a vision-related task. In recent years, with the rapid development of cities, especially the rapid increase of vehicles, traffic problems have become an urgent problem to be solved in urban management. Traffic problems have seriously hindered the develo...
