摘要
结构光作为一种非接触式主动三维测量方法得到了快速发展。基于结构光原理的相位编码方法将码字以相位的形式嵌入到条纹的强度中,由于使用相位而不是强度来确定码字,对表面对比度、环境光和相机噪声不敏感,具有较强的鲁棒性。文中回顾了基于相位编码的三维测量技术研究进展,综述了基于相位编码的三维测量原理,包括初始相位的设计方法、编码条纹的产生方法、相位计算方法、条纹级次的获取与校正以及最终绝对相位的获取,给出了相关的实验结果,并指出了相位编码方法中的优缺点。最后,讨论了该技术面临的挑战,并指出了该领域今后的发展方向。
Abstract
Structured light has developed rapidly as a non-contact active three-dimensional measurement method. The phase coding method based on the principle of structured light embeds the codeword into the intensity of the fringe in the form of phase, which is insensitive to surface contrast, ambient light and camera noise due to the use of phase instead of intensity to determine the code word, so it has stronger robustness. The research progress of three dimensional measurement methods of phase-coding was reviewed, and the three-dimensional measurement principles based on phase encoding was summarized, including the design method of initial phase, the generation method of encoded fringes, phase calculation methods, acquisition and correction of fringe order, and acquisition of absolute phase. Some experimental results were given, and the advantages and disadvantages of the phase coding method were pointed out. Finally, the challenges faced by the technology were discussed, and the future development direction of the field was pointed out.
