基于互补型光栅编码的相位展开

为了解决在运用相移技术和二元光栅编码结构光进行相位展丌时存在的误码问题,提出了一种新的互补型二元光栅编码.通过多投一幅格雷码图案,并利用格雷码相邻码字之间Hamming距离为1的特点,没计出互补的两种编解码方式.利用两种编码出现误码位置的不同,并结合相移技术解决了去包裹过程中的误码问题.论述了互补型二元光栅编码的设计方法及特点,并详细分析了基于互补型二元光栅编码的相位展开过程.计算机模拟和三维重建实验清楚地表明,提出的互补型光栅编码能很好地解决了误码问题且具有很高的可靠性.

Phase-Unwrapping Based on Complementary Structured Light Binary Code

In order to solve the problem of error code in the field of phase unwrapping based on phase-shift technology combined with structured light binary code,a new complementary structured light binary code was presented.Two kinds of complementary encoding and decoding modes were designed by projecting one more Gray code image as well as taking advantage of the property of Gray code that the Hamming distance of the neighbor code is one.By using the new codes which mode error code happen at different positions,and...
