摘要

利用结构光进行距离图像测量已经得到了广泛的应用。提出了一种采用调制模式的新型结构光。通过模式光的投影和时域信号处理,可以更准确地获取物体的三维几何信息。通过使用匹配滤波器提取图像中的结构光,可以从多个位置同时投射多个结构光,以减少遮挡问题。本文通过实验介绍了这种新方法。

Range finding with simultaneous projection of modulated patterns
Range image measurement using structured light has been widely utilized. A new structured light employing modulated patterns is proposed. By projecting the pattern light and signal processing in time domain, it is possible to obtain the 3D geometric information of objects more accurately. By using a matched filter to extract the structured light in an image, it is possible to project multiple structured light from several positions simultaneously for reducing occlusion problem. This paper describes the new method with some experiments.
