<P>PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of accurately determining abnormality of imaging means. <P>SOLUTION: An object detection apparatus is to calculate a corresponding point on the basis of a plurality of images by a plurality of imaging means 2R, 2L and detect an object on the basis of the calculated corresponding point, and comprises feature point extraction means for extracting a feature point of each image; feature point number measurement means for measuring the number of feature points; corresponding point detection means for detecting feature points existent in common in a plurality of images among feature points as the corresponding points; and corresponding point number measurement means for measuring the number of the corresponding points. The corresponding point detection means retrieves the corresponding points only for a predetermined region of an image, and judges that an optical axis of the imaging means is abnormal when the number of the corresponding points to that of the feature points is less than a predetermined reference. <P>COPYRIGHT: (C)2007,JPO&INPIT |
