摘要:
针对传统大视场成像设备难以兼顾高分辨率和实时性的问题,通过模仿昆虫曲面多目复眼结构,提出一种基于多相机阵列的球面复眼设备设计方法.该方法利用相机原始矩形视场对预定视场进行分割,根据矩形视场存在水平、垂直 ２ 个视场角的特点,通过对球壳纬度层和经度层 ２ 个方向的分割,在无缝分割的前提下,最大限度地降低相邻相机间的重叠区域,提高相机的利用效率,降低系统复杂度.基于该设计方法,采用水平视场角、垂直视场角及分辨率为 ２００ 万的 ７ 个完全相同的相机制作了一款 ２ 层的仿生复眼,并利用该设备实现了视角为 ７９．５° ,分辨率为 １２００ 万的全景成像,证明了该设计方法的有效性.
Abstract:
Aiming at the problem of traditional large-field imaging equipment that is difficult to balance high resolution and real-time performance , this paper proposes a multi-camera array-based spherical compound eye device design method by simulating the structure of insect curved multi-eye compound eyes．This method uses the camera＇s original rectangular field of view to divide the predetermined field of view．According to the rectangular field of view , there are two horizontal and vertical field angles．By dividing the spherical shell in two directions , the latitude layer and the longitude layer are seamlessly divided．Under the premise of seamless segmentation , the overlapping area between adjacent cameras is minimized , the utilization efficiency of cameras is improved , and the system complexity is reduced．Based on this design method , a ２-layer bionic compound eye was fabricated using seven identical cameras with horizontal and vertical field angles and a resolution of ２ million , and a panoramic imaging with a perspective of ７９．５ and a resolution of １２million was achieved by using this device , which proved the effectiveness of the design method．
