Spherical Light Source Based Shape from Shading Method
It will be very useful if shape recovery can be performed under indoor lights which maybe spherical shape. As a first step towards this goal a spherical light source model is developed for doing shape recovery. This model is more practical and convenient than other extended light source model. Base on it, the shape from shading method can be used to recover surface shape from one image. Our method is verified by both real and simulated experiments. The results show that this light source model is convenient and method for shape recovering is accurate.
