摘要

陶瓷、金属等光滑表面的强反射性质，会使图像饱和产生高光现象，导致测量精度大幅下降。针对这一问题，本文利用扩散板对光的扩散作用，设计了基于线性扩散板的高光抑制系统。首先从理论上研究线性扩散板的扩散原理，并利用高光点反射辐射亮度分析线性扩散板对高光的抑制作用。然后搭建系统平台，完成相机标定、投影仪标定等系统搭建工作。最后对陶瓷盘子和大理石罐等具有强反射表面的物体进行三维测量，实验结果表明，线性扩散板能够实现三维测量中强反射表面的高光抑制，其中大理石罐、陶瓷盘子、花盆、杯子的高光点数目相比未加扩散板时分别减少了19.6倍、5.6倍、4.4倍与3.9倍。扩散板能够减弱高光点的反射辐射亮度，对高光具有一定的抑制作用，三维重构结果中高光区域明显缩小。

Abstract

Due to the strong reflection property of materials with smooth surfaces like ceramic and metal

it will cause saturation and the highlight phenomenon in the image when taking pictures of those materials. Focused on that problem and taking advantage of the diffusion effect of the diffuser

we design a highlight suppression system based on the linear diffuser. Primarily

we theoretically analyze the diffusing principle of the linear diffuser. Besides

we also analyze the highlight suppressing effect of the diffuser with reflected radiance of the highlight points. Then

we build up the system platform and complete the camera calibration and projector calibration. Finally

we implement 3D experiments on objects with strong reflecting surfaces like ceramic plate and marble can. Experimental results show that with the help of the linear diffuser

the highlight caused by the strong reflecting surface can be well suppressed. The highlight pixel numbers of marble can

ceramic plate

flower pot and cup are decreased by 19.6 times

respectively

5.6 times

4.4 times and 3.9 times

respectively. Diffuser can reduce the reflected radiation of highlight points and suppress highlight. Three-dimensional reconstruction results show that highlight areas were significantly reduced.
