Abstract :
A range intensity image, which is also called a reflectance image, refers to the intensity image that is acquired simultaneously with the range image captured using an active range sensor. This paper proposes a method that uses this image to correct the color information of a textured 3D model. The color information is usually obtained by texture mapping of color images acquired by a digital camera. The lighting condition for the color images are usually not controlled, thus the color information is not precise. On the other hand, the lighting condition for the range intensity image is controlled since it is obtained from a controlled and known lighting as required for the purpose of range measurement. The paper describes the method for combining the two sources of information; experiments show the effectiveness of the correction method.
