摘要 针对目前曲面光顺算法存在的问题,提出了一种由平滑曲面在平行光照射下图像达到光顺的思想而形成的曲面光顺算法。该算法直接平滑曲面在平行光照射下的图像,然后通过光度立体技术反求出光顺后的曲面。由于能直接平滑曲面在平行光照射下的图像,使得光顺后的曲面在基于光照模型的曲面光顺准则下具有很好的光顺性质。应用实例显示,该算法能在保持原曲面形态的基础上达到很好的光顺效果。 This paper presents a new method for fairing of surface based on smoothing the photometric image of surface.It smoothes the photometric image of surface by some existing method in digital image processing,then gets an approach es to original surface by the photometric stereo technology.Practical examples are given to show the results obtained with the presented algorithm.
