Abstract: The surface luminance perception is one of the most important aspects of achieving an overall appearance for a paper-based model. The accuracy and rapidity of luminance perception directly affect the visual perception of the overall appearace of the paper-based model. In this paper, the surface luminance prediction based different surface set angles and surface tone values was performed by measuring the surface luminance of 3D paper-based model. First, a rotating bracket was designed to facilitate to set the paper surface angle.Then, we set the angle from 0 to 85° at the interval of 5° using the designed rotating bracket. In addition, the four primary color scales, cyan, magenta, yellow, and black, were printed and set at the designed angle. The angle-ware and tone-ware luminance was measured using spectroradiometer, CS-2000. Finally, we proposed and evaluated a mathematical model to reveal the relationship between luminance and surface set angles and surface tones using the least squares polynomial method. The results indicated that the surface luminance of 3D paper-based model could be predicted and obtained quickly and accurately for any surface set angles and surface tone values by the proposed prediction model.
