Abstract

In computer vision, it is one of the important subjects to estimate 3D shapes of objects from a 2D view. As a means of solving this problem, there is a method of using knowledge about objects for understanding a 2D view. This article presents a method to acquire shape data of objects from industrial sketches using knowledge about objects and to construct 3D models. Knowledge including uncertainty is used in the image processing. The processes are performed using the concept of likelihoods since the discussion using ambiguous knowledge are also ambiguous. Three-dimensional data of objects are acquired from industrial sketches, and then object models are constructed using bicubic Bezier surfaces.
