单目多视点立体图像提取及应用

设计并实现了一种基于广角相机和平面镜的单目多视点立体图像摄像系统,给出了硬件装置的设计指标和优化方法;同时,在研究了硬件系统的标定方法基础上,实现了其在三维测距方面的应用。多枚平面镜构成的对称斗型腔体被放置在广角相机前面,物体光线经过不同平面镜反射后,投影到相机图像平面的不同区域,在相机投影平面上生成物体多个影像,形成单目多视点投影图像。该类图像等价于视点不同的多幅图像,可以使用多视点立体视觉算法实现三维测量。

Monocular Multi-Viewpoints Stereo Imaging and Application

A monocular imaging system is designed to capture the multi-viewpoints stereo images. Several identical isosceles trapezoidal planar mirrors are placed around a wide view-angle camera. The light rays from an object projected onto the camera include direct light and the light reflected by the mirrors, and divide the camera′s image into several regions; thus a multi-viewpoints image is captured. These regions correspond to observations with multiple cameras at different positions and orientations, and can be used for multi-views stereo images to reconstruct three-dimensional (3D) information. The system design guideline and calibration method are described, and an application of 3D shape measurement is proposed. Experimental results indicate that the proposed system can capture monocular multi-viewpoints stereo images, and achieve highly robust 3D measurement.
