摘要
针对传统折反射全景成像系统的图像必须依赖展开技术的问题, 提出一种基于仿视网膜成像器件的折反射全景系统设计。利用国内首款仿视网膜CMOS探测器各环上像元与周向、径向空间瞬时视场的对应关系, 推导了双曲面反射镜的镜面参数, 构建了基于BIT Retina52探测器的全景成像系统。系统实现了无需坐标变换的全景图像直接输出, 较之传统折反射成像系统, 改善了空间角分辨率变尺度分布问题。
Abstract
For the problem that the image of the traditional catadioptric panorama system must rely on the technology of image unwraping, a design of a catadioptric panorama system based on retina-like imaging device is presented. Based on the first retina-like CMOS sensor in China, according to the correspondence between the pixels on each ring and the Instantaneous Field of View in circumferential and radial space, the specular parameters of the hyperboloid mirror are deduced, and a panoramic imaging system based on BIT Retina52 sensor is constructed. The system achieves the goal that the panorama image without coordinate transformation is output directly, compared with the traditional catadioptric panorama imaging system, the variable scale distribution problem of the spatial angle resolution is improved.
