A traffic information acquisition system based on linear array CCD video camera imaging

Abstract

The invention discloses a traffic information acquiring system based on linear CCD imaging, which comprises two linear CCD cameras spaced at a certain interval and disposed on a support above two road sections, each is provided with an auxiliary lighting headlight; and a plurality of auxiliary planar array cameras arranged at the position 15 m away from the front of the two linear CCD cameras and respectively located on the middle of a driveway and on the separating line of the driveway, wherein the auxiliary planar array cameras in the middle of the driveway can shoot vehicles passing the road, and the auxiliary planar array cameras in the driveway separating line can perform panning shot. When the vehicles pass the road section, the linear CCD cameras can acquire linear image data of the vehicles passing the road section; the acquired linear image data is processed and analyzed to obtain traffic parameters such as traffic flow, vehicle velocity, traffic stream density and road occupation rate, and the planar array cameras can shoot vehicle image which is analyzed and processed to obtain license plate information.

Description

technical field [0001] The invention belongs to the technical field of video processing, and relates to a traffic information collection system, in particular to a traffic information collection system based on linear array CCD imaging. The line array image acquires various traffic information parameters such as vehicle presence, vehicle speed, vehicle plane profile, vehicle type, traffic occupancy rate and flow, etc., to realize the monitoring and evaluation of road traffic conditions and the real-time detection of traffic incidents. technical background [0002] The real-time collection of road traffic information is one of the key contents of intelligent traffic information collection. It detects various traffic parameters such as traffic flow, vehicle speed, traffic density and road occupancy rate in real time on the road, and provides a basis for traffic planning, traffic management, and road maintenance. The department provides important data and execution basis, and p...
