IMAGE PROCESSING APPARATUS, TRAFFIC MANAGEMENT SYSTEM WITH THE SAME, AND IMAGE PROCESSING METHOD

Japanese Patent JP2017022492

A

PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of accurately reproducing colors of a traffic light included in a captured image around the traffic light, a traffic management system comprising the same and an image processing method.SOLUTION: An image processing apparatus 10 comprises an image acquisition part 13, a signal detection part 16, a color discrimination part 17 and a color setting part 18. The image acquisition part 13 acquires an infrared image from a camera 103 that images the surroundings of a traffic light. The signal detection part 16 detects a light-emitting position of the traffic light included in the acquired infrared image. The color discrimination part 17 acquires information relating to the detected light-emitting position and refers to a design layout of the traffic light to determine a color of the traffic light included in a monochromatic image acquired in the image acquisition part 13. The color setting part 18 performs color scheme processing on a region at the detected light-emitting position of the traffic light included in the infrared image in such a manner that the region becomes the color of the traffic light determined in the color discrimination part 17, and outputs an image in which the region of the traffic light is colored.SELECTED DRAWING: Figure 1
