一种新的不可见结构光算法

A Novel Imperceptible Structured-Light Pattern Algorithm

本文提出了一种新颖的自适应不可见结构光的投影技术。该技术可以将任意的二值结构光图像嵌入到普通的原始投影图像中。由于投影仪高速投影,人眼是很难发觉嵌在图像中结构光信息。然后利用与投影仪同步的高速摄像头捕捉到的嵌入结构光编码图像,还原出结构光图像。本文的特色在于提供一种新型的嵌入结构光的编解码算法,该算法可以在保证结构光视觉不可见的前提下,使结构光还原图像的精度提高到像素级。

This paper proposes a novel adaptive imperceptible structured-light projection technology, which could embed arbitrary binary structured-light pattern into ordinary source projective image. Because of high-speed projector, it is hard for people to be conscious of the embedded structured-light information in the image. And then the high-frequency camera synchronizes with the projector, could capture embedded structure-light pattern image. The structured-light pattern could be gotten by those embedded image finally. This paper introduces a new method to code and decode embedded structure-light. This method could increase the precision of embedded structured-light by pixel-level when embedded information is imperceptible.
