摘要
传统的视度视差测量装置都采用平行光管视差仪或者视度筒进行测量,人为主观因素对测量结果影响较大。本文设计了一种基于CCD成像的短焦摄像系统,测量器件采用高分辨率CCD,经过图像处理后由计算机给出测量结果,消除了人为主观因素影响,视度测量精度达到0.05屈光度,给出了视度视差计算公式,并对系统进行了误差分析。
The traditional diopter and optical parallax testing systems usually use the collimator parallax instrument or diopter cylinder to measure,human subjective factors impact on the measurement results. This paper designs a short-focus camera system based on the CCD imaging,using the high-resolution CCD as measuring device. The measurement results are given by the computer after image processing,the impact of human factors is eliminated,and the measurement accuracy is up to 0.05 diopters. The formula of calculating the diopter and optical parallax is given,and the system errors are analyzed at the same time.
