ABSTRACT:
A method and an apparatus for accurately detecting and reconstructing the shape of a curved surface of a subject. The apparatus is provided with an image detecting part for photographing a subject from two different positions and detecting gradational images seen from the respective positions, and a curved surface reconstructing part for computing a luminance ratio of pixels corresponding to each other in the different gradational images, computing an inclination of a surface of the subject on the basis of this luminance ratio, and reconstructing a curved surface of the subject. The method obtains an inclination of the surface of the first observed part by obtaining inclinations of the surfaces of the second and the third observed part which are adjacent to the first observed part and taking an average of these first and second inclinations.
