摘要
According to the present invention, a method of linking and tracking an object and detecting a lane changing vehicle between cameras in a tunnel comprises: a step where a lane change detection control unit for detecting a lane change in a tunnel uses an entrance side number recognition camera installed at an entrance of the tunnel to detect and store a color vector of a vehicle entering into the tunnel, vehicle recognition time, a vehicle type, a license plate number, and a lane position of the entering vehicle; a step where the lane change detection control unit uses the color vector, the vehicle recognition time, and the vehicle type of the previously detected vehicle entering the entrance of the tunnel in the video of the tunnel recorded by a monitoring camera to link and track the vehicle entering the tunnel and generate a lane change event when the tracked vehicle changes lanes in the tunnel; a step where the lane change detection control unit uses an exit side number recognition camera installed at an exit of the tunnel to detect and store a color vector of a vehicle exiting from the exit of the tunnel, vehicle recognition time, a vehicle type, a license plate number, and lane position of an entering vehicle; and a step where the lane change detection control unit determines a vehicle as a lane change violation vehicle to store the license plate number for the lane changing vehicle, an event image when changing the lane, and a vehicle image photographed when passing through the entrance and exit of the tunnel when lane positions are different when a vehicle having an identical license plate number enters the tunnel and when the vehicle exits from the tunnel or if a lane change event is generated in the tunnel even if the lane positions are identical when the vehicle having the identical license plate number enters the tunnel and when the vehicle exits the tunnel.
