    • An outer environment of the vehicle is inputted as an image. Image processing is performed to the input image, and many edge segments are extracted. The edge segments which are colinear are clustered in order to perform a matching operation. Matching is performed in a respective set of plural longer edge segments representing plural clusters in correspondence with a set of plural guide signs as standards of guide of the vehicle mapped on the image input surface, and a set of longer edge segments being most matched each other is extracted. From position and headings of the extracted longer edge segments on the image input surface, the position and heading in the outer environment are calculated. The position and heading of the vehicle are detected from these values. The position and heading of the vehicle obtained in the above-mentioned image processing and the position and heading of the vehicle measured by other techniques and are evaluated synthetically. When the guide signs are mapped on the image input surface, the forecast values of position and heading of the vehicle at the image input time are used. In this manner, the detecting accuracy of the position and heading of the vehicle is improved.

    • Detecting with good precision an eye inside corner position and an eye outside corner position as face feature points even when the eye inside corner and/or the eye outside corner portions are obscured by noise. First eyelid profile modeling is performed with a Bezier curve expressed by a fixed control point P3 indicating an eye inside corner first position detected in an image, a fixed control point P4 indicating an eye outside corner first position, a control point P1 corresponding to an upper eyelid position candidate (first parameter), and a control point P2 corresponding to a lower eyelid position candidate (second parameter). Then in a second eyelid profile model with fixed P1 and P2 of the first eyelid profile model having the highest fitting evaluation value λ to the eyelid profile in the image, the values of a control point P3 indicating an eye inside corner position candidate (third parameter) and a control point P4 indicating an eye outside corner candidate (fourth parameter) at a maximum of a fitting evaluation value λ when changing the values of the control point P3 and control point P4 are determined as an eye inside corner second position and an eye outside corner second position, respectively.
