摘要： 纸基模型表面亮度感知是整体色貌感知的重要组成，亮度感知的准确性、快捷性直接影响到纸基模型整体外貌的视觉感知。本文通过对3D纸基模型表面亮度测量，实现3D纸基表面在不同角度、不同阶调时的亮度预测。首先，通过设计的纸模测量角度架，可以方便快捷地调整纸基表面角度，然后，确定测量角度取样间隔为5°，纸模表面角度为5°~85°，依次测量，最后，设计四色表面梯尺，青色、品色、黄色、黑色在不同纸基表面和不同阶调下，利用辐射亮度计对其表面亮度值进行测量。利用最小二乘法建立亮度与纸基表面角度、阶调之间的关系模型，并对模型优劣程度进行检验。结果表明，本预测模型可以快速准确地对任意角度3D纸基表面进行亮度预测，获取3D纸基模型表面的亮度。

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.
