Rapidly constructing a simple 3-D graphic model using a consumer-user digital still camera

Abstract

Constructing 3-D graphic image models in general uses expensive equipment so that it is difficult to develop 3-D images as popular graphics in the world. In this paper, a 3-D graphic model constructed using a consumer-user digital still camera is proposed. A simple scene is set up to conveniently process the images, captured by the consumer-user digital still camera, for 3-D graphics. Besides, the 3-D graphic model expressed by color and model matrices is approximated by six surfaces including front, left, back, right, top and bottom. The six-surface images of an object captured by the consumer-user digital still camera sculpture the 3-D graphic body to form a model matrix, and then all the six view images sequentially fill their color information in proper element of color matrix according to the finished model matrix and their view relationship. Once color and model matrices are prepared well, the complete 3-D graphics model can be obtained by combining them together. The work of constructing a 3-D graphic model is depicted by six Pseudo Codes and summarized by two procedures. The proposed 3-D graphic model wastes 633.6 KB at image resolution 160x120 pixels, and 3.6864 MB at image resolution 320x240 pixels. The 3-D graphic model constructed by quick procedures, and using less memory makes 3-D images used in handheld devices possible. In addition, four objects: mobile phone, stapler, correction tape and small clock, used as illustrative examples for demonstrating the 3-D graphic model are included(1).
