針對目前細(xì)度計(jì)量的要求,提出了圖像計(jì)量的方法,詳細(xì)論述了圖像計(jì)量的基本原理,傳感器建模方法. 通過標(biāo)準(zhǔn)比對和圖像變換方法實(shí)現(xiàn)了對物體的細(xì)度計(jì)量. 同時(shí)在MATLAB 和Photoshop6. 0 的基礎(chǔ)上使用C 語言編程,建立了一套圖像細(xì)度計(jì)量系統(tǒng). 能夠完成對物體細(xì)度的自動(dòng)計(jì)量、自動(dòng)存儲(chǔ)、自動(dòng)邊緣跟蹤等功能. 同傳統(tǒng)的細(xì)度計(jì)量方法相比,本系統(tǒng)操作簡單,速度快,可重復(fù)性好. 實(shí)踐證明,通過使用圖像計(jì)量技術(shù),細(xì)度計(jì)量精度可以達(dá)到5 %左右.

Abstract :The image met rology is int roduced for fineness measurement by image t ransformation and norma2 tive comparison. A image fineness measurement system is established using C language programme on the basis of MATLAB and Photoshop 6. 0 which can realize automatic Met rology ,automatic memory , automat2 ic edge following ,etc. A precision 5 % or so can be achieved using image met rology technology.
Key words :image met rology ;fineness ;image t ransformation ;image sensor
