A CG Modeling System by using VTR Image Sequences

Abstract

Recently, for creating realistic computer graphics (CG), it has been increasingly requested to obtain 3DCG models (3D shapes and textures) from photographs and movies. We have proposed a system construction method which can extract 3DCG models by user's simple operation from a series of image taken with normal cameras and videos.
The method is consisted of two phases-to extract partial models and to combine those models for creating a complete model. On the first phase, the operator input some feature (points, edges, planes) to each image. On the second phase, the operator just select several pairs of feature points of the adjacent partial models. Additionally, this method has the function to correct the shapes of each model by changing only two parameters.
This paper represents the principles, procedure and operational examples of the proposed method. It also shows an experimental result of model extraction accuracy and discusses the characteristics of the proposed method.
