Method for detecting traffic sign board in intelligent vehicle and system for executing the method

PURPOSE: A method for detecting traffic sign board and a system for executing the method are provided to control a background region and to reinforce the color contrast feature of an image. CONSTITUTION: A traffic sign board detection system inputs a sign board shape and a symbol shape of a traffic sign board installed on a real road into a database(S101). A color-to-feature map and an outline feature map are calculated in an input image(S105). A color tone contrast feature map and contour line feature map are used. An image enhanced map is generated using the color-to-feature map and outline feature map(S106). A traffic sign board within the input image is detected using the image enhanced map(S109).
