查询词典 optic

A novel method of measuring plus lens's focus is given, which is based on LCD, CCD, and digital image processing It is also a discussion on photoelectric method of automatically measuring parameters of an optic system In this method, a LCD is used as a reticle of the collimator, while the image on the accepting side is transformed into digital image and is sent into a computer The focus can finally be calculated out through digital image processing and analysis The method of measurement is introduce...

讨论了一种基于LCD、CCD和数字图像处理的正透镜焦距测量方法，是光电法自动化测量光学系统多个参数的一种有益的探讨。用液晶屏显示分划图形取代平行光管的分划板，用CCD在接收方采集数字图像并送入计算机，通过图像处理和分析得出被测透镜的焦距。运用叠加的方法提高图像的信噪比；结合重心法和平行线拟合方法求取平行线对的间距；应用高精度焦距标准透镜标定数字图像和实际像之间的比例关系。详细介绍了测量和图像处理的方法，进行了公式推导和误差分析，并给出了实验结果
