ABSTRACT:
A method and an apparatus for constructing three-dimensional surface shading image display from three-dimensional sequential tomographic images, capable of obtaining the distance image at a high speed by using a hardware configuration with a high general applicability. In the apparatus, an individual distance image for each of the tomographic images with respect to a predetermined reference plane is constructed; a synthesized distance image in which the individual distance images for all of the tomographic images are synthesized together is constructed, by sequentially carrying out an image extrema calculation between each individual distance image for each tomographic image and a previous synthesized distance image; a distance image for surface shading is constructed by applying an affine transformation to the synthesized distance image; and a surface shading image is obtained by applying a shading process to the distance image for surface shading. The image extrema calculation can be either an image minima calculation or an image maxima calculation.
