摘要
展示了所构建的基于四平面镜的单相机三维(3D)采集系统, 介绍了系统所采用的三维扫描的几何光路, 分析了从图像解析出高度的3D采集算法、空间分辨率与图像分辨率的关系, 也讨论了算法的优化以及3D再现技术。从实验结果可以看出, 与采用激光扫描的3D采集系统相比, 基于镜像视差的3D采集系统, 结构更简单, 而且可以同时采集出物体的空间结构和表面纹理颜色, 是一种有效的3D采集手段。
Abstract
A three-dimensional (3D) scanning system based on a single camera of four planar mirrors is presented. The 3D scanning geometric path of the system is introduced. The 3D height acquisition algorithm, the relationship between spatial resolution and image resolution are analyzed. The techniques of algorithm optimization and 3D reproduction are also discussed. The result shows that, compared with those 3D scanning methods using laser scanning, this proposed system based on mirror parallax is an effective 3D acquisition method because it can capture the spatial structure and color texture of a surface simultaneously, and the structure is simple.
