A HIGH-QUALITY 3D MULTIVIEW MODEL-BUILDING TECHNIQUE BASED ON CAD

In this paper, we propose a method for building a high-quality 3D model efficiently from a CAD model. We automatically build the high-quality 3D model of an object by accurately extracting the 3D multiview features from the CAD model with the object-precision method instead of the existing image-precision method. Precision of the features from the image-precision method is limited to the precision of the image resolution and varies with the view distance and view-up vector. Since we exploit the object-precision method to extract the 3D multiview features, the precision of the features is equal to the precision at which the object is defined in the CAD and is independent of the view distance and view-up vector.
