We proposed a method to reconstruct the shape from multiple images taken with fiber scope. If the position and inclination of the imaging device is known, since the direction of the ray of the pixel of the imaging device is determined, using a point that was three dimensionally discrete as the position of the reflector. The image obtained with the light intensity from each position is determined the light intensity of each point by the least squares method so as to be closest. It was confirmed that it is possible to reconstruct the shape by the proposed method of what remains an error.
