Modeling and Calibrating on Object Space Location

从对单目视觉系统的空间定位技术着眼,本文研究了一种利用标准平面镜反射辅助三维空间测量的模型和方法。首先基于摄像机标定的基本原理,以条纹反射检测系统为初始结构,建立应用标准镜测量显示屏的空间位姿的物理模型,然后在对摄像机标定不确定度进行实验标定的基础上,进行了对条纹反射检测系统的三维空间位姿描述和测量。研究结果验证了本文技术方法模型有效、精度较高,扩大了单目视觉系统的测量范围,获得了更加紧凑的物像空间位姿测量系统结构。

Aiming at the space location based on monocular vision system,a method by using standard plane mirror to make space measurement is introduced.First,the principle of camera calibration is presented,by taking the fringe reflection test system,a physical model for measuring the space position of the LED screen with a standard mirror is studied.Then,based on the uncertainty experiment of camera calibration,the 3 D space position measurement of the fringe reflection system is completed.Experimental results show that the measuring range of the monocular vision system is expanded and the system construct is more compact.
