SYSTEM FOR CONTROLLING VEHICLE TRANSPORT SIGNAL OF INTERSECTION USING DAY AND NIGHT INTEGRATED TRAFFIC IMAGE DETECTOR

摘要

PURPOSE: A system for controlling the vehicle transport signal of intersection using a day and night integrated traffic image detector is provided to minimize the interference of external illumination by improving the performance of an image detector at an intersection. CONSTITUTION: A day and night control device(330) determines a day mode or a night mode. An image obtaining controller(320) generates the day mode or infrared ray mode of a camera and generates a camera operation control signal. The image obtaining controller collects the capture image of vehicle entering and exiting. A digital signal processing unit(340) generates a traffic information message which includes the number of the vehicle waiting at lanes.
