Abstract
An obstacle detection system and a method thereof The obstacle detection system comprises an object detection module used to generate a detected distance and a detected direction of a external obstacle; a camera module used to capture a camera image including an obstacle image; a calculation module used to calculate a first region for the obstacle image in the camera image; and an object search module used to execute a first image processing on the camera image within the first region to obtain the obstacle image. If no obstacle is found within the first region, the calculation module is used to calculate a second region. The object search module is used to execute a second image processing within the second region to obtain the obstacle image.
