摘要
详细介绍了一种基于相移结构光照明的浮雕成像技术, 对该成像技术的原理和成像特性进行了实验研究, 并采用相移结构光照明的方法实现彩色浮雕成像。实验中, 将多幅相移正弦条纹光场斜投射到被拍摄物体上, 数码相机依次拍摄被照明的物体, 再利用拍摄到的多幅相移图像, 通过计算的方法重建出所需要的图像。理论分析和实验结果表明, 相移结构光照明成像技术能有效地消去环境不均匀光照的影响, 获取的反射率分布图像只与结构光照明有关, 突显了斜投射照明所形成的阴影, 图像的明暗变化反映出物体表面的法线变化, 因而在视觉上形成了明显的浮雕效果。
Abstract
This paper introduces a kind of embossed imaging technology based on phase-shifted structured light illumination. The principle and imaging characteristics of imaging technology are studied experimentally, and color embossed imaging is realized by phase-shifted illumination method. In our experiments, multi-steps phase-shifting sinusoidal patterns are projected obliquely onto the object to be photographed, and digital camera sequentially captures illuminated object, and then reconstructs desired image by calculated method using multiple captured images. Theoretical analysis and experimental results show that phase shift structured light illumination imaging technique can effectively eliminate influence of environment uneven illumination. The obtained reflectance distribution image is only related to structural light illumination, which highlights shadows formed by oblique projection illumination. Change of light and shade reflects normal variation of object surface, and thus apparent embossing effect is formed visually.
