摘要
时空立体视觉是一种全新的三维重建技术,它利用主动光源来改变图像灰度,通过比较某时间段内的图像序列来完成立体匹配。针对时空立体视觉的特点,设计了一种由多级对偶的和沿一维单调变化的"锯齿式"灰度条纹组成的光源,提高了鲁棒性。三维重建实验结果说明了该光源的有效性。
Spacetime stereo is a novel technique for t^lree dimensions （3D） reconstruction, which uses active illumination to change the internsities of images and implements stereo matching by comparing the image sequence during a period of time. Aim- ing at the characteristic of spacetime stereo, a light pattern, which consists of multi-level dual “saw-tooth” stripe gray light changing monotonously in one-dimension, is designed to increase the robustness of the technique. The experiment results of 3D reconstruction validate the effective of the light pattern.
