Abstract
In the medical imaging applications, endoscope image is used to observe the human body. As a method to recover 3-D shape from shading images, light fall-off stereo has been proposed using the inverse square law for illuminance with point light source illumination. This paper extends the principle of light fall-off stereo and proposes a new approach under the assumption of both point light source illumination and perspective projection using two images with the different size of target object. To solve the problem that target has the specular reflectance in general, removing the points with specular components and interpolating the surface can handle the target with specular reflectance. The proposed approach is demonstrated through computer simulation and real experiment.
