Abstract:
A 3D model conversion apparatus for measuring the shape of a 3D body based on a plurality of images and converting it into a 3D model, the apparatus comprising:an image input portion for reading in a plurality of the images; an image storing portion for storing the images that have been read in; a base model memory portion for storing base models expressing reference bodies included in the images; a base model selecting portion for selecting a base model defining a geometric quality of a body in the images, which is to be converted; an image calibration portion for performing a plurality of image calibrations based on the selected base model, and superimposing the base model on the images to determine 3D coordinates of vertices of the base model; a face configuration and corresponding points designating portion for designating at least one new vertex on the images projected from at least two different points of view and configuring a surface, which is generated by designating the new vertices, based on the result of the image calibrations and the previously determined 3D coordinates of the vertices of the base model; a 3D information calculation portion for calculating 3D positional information of the new vertices when the new vertices are being designated; a 3D shape display portion for displaying a 3D model of the body, which is to be converted by adding the new vertices; a texture image generating portion for generating a texture image to be pasted on a surface of the 3D model, based on a correspondence relation between the 3D model that is finally obtained by addition of the new vertices and the images; a generated model output portion for outputting data of the completed 3D model.
