In recent years, it is required to develop 3D (three dimensional) imaging systems to capture and reproduce the color, glossiness and shape of the object accurately for digital archives. Our final goal of the research is to construct digital archival systems in museum and Internet or virtual museum via World Wide Web. To archive our goal, we have developed Gonio photometric imaging system to record and estimate reflectance spectra of the 3D object based on principal component analysis and Wiener estimation method. Five-band images of the object are taken under different illumination angles by using developed multi-spectral camera. Dichromatic reflection model and Phong model are introduced to obtain Gonio spectral image. Those obtained images are synthesized with 3D wire frame images taken by 3D camera used laser projection by using Open GL algorithm.
