摘要
为了扩大镜像双目视觉传感器的视场范围,采用球面反射镜替换平面反射镜成为一种有效方案。但利用凸球面镜进行反射成像,将会导致图像质量和清晰度的下降,为此研究单相机镜像双目视觉传感器的光学特性。以离轴非中心式球面镜反射为研究对象,建立不同光学特性的成像模型,通过仿真和实验来定量分析球面镜参数对视场范围、分辨率和景深的影响,在给定工业相机和光学镜头参数的情况下给出双球面镜参数的设计方法。搭建基于单相机和双球面镜的视觉传感器,该传感器可以实现镜像双目视觉成像。通过分析基于球面镜反射的视觉传感器的光学特性,为新型镜像双目视觉传感器的设计提供了依据。
In order to expand the field of view of the mirror binocular vision sensor,it is an effective scheme to replace planar mirror with spherical mirror.However,the reflection imaging with convex mirror will lead to the decline of image quality and sharpness,so the optical characteristics of binocular vision sensor for single camera mirror are studied.Taking the off-axis non-central spherical mirror as the research object,the imaging models with different optical characteristics are established.The effects of spherical mirror parameters on field range,resolution,and depth of field are quantitatively analyzed by simulation and experiment.The design method of double spherical mirror parameters is given under the condition of industrial camera and optical lens parameters.A vision sensor based on single camera and double spherical mirror is constructed,which can realize mirror binocular vision imaging.By analyzing the optical characteristics of the vision sensor based on spherical mirror reflection,it provides a basis for the design of a new mirror binocular vision sensor.
