Abstract
According to an apparatus and method for detecting an obstacle through stereovision, an image capturing module comprises a plurality of cameras and is used for capturing a plurality of images; an image processing module edge-detecting the image to generate a plurality of edge objects and object information corresponding to each edge object; an object detection module matches a focus and a horizontal spacing interval of the camera according to the object information to generate a relative object distance corresponding to each edge object; a group module compares the relative object distance with a threshold distance and groups the edge objects with the relative object distance smaller than the threshold distance to be an obstacle and obtains a relative obstacle distance corresponding to the obstacle.
