Description

Recently, the number of pixels of amateur digital cameras is amazingly increasing by modern semiconductor and digital technology. Nevertheless the highest pixel of amateur digital camera was 0.8 mega pixels in the 1996, 5.24 mega pixels was achieved in the 2001 and 3 mega pixels amateur digital cameras became the most popular camera on the market in Japan. In these circumstances, it is expected that the high resolution amateur digital cameras will become useful tool in various photogrammetric fields.<BR>With this objective, the authors have been concentrating on developing a low-cost photogrammetric system using a digital amateur camera. This paper reports performance evaluation of 3 mega pixels amateur digital camera, a low-cost photogrammetric system, and the software“3DiVisoin”which was designed to perform convenient 3D measurements using amateur digital camera with key words: 3Dimension, Digital image and Visualization. Furthermore, 3D modeling of historical structure which was designated as important cultural assets using the 3DiVision was introduced.
