The feasibility of above schemes was proved by large numbers of experiments . then , two autofocus systems based on pc and dsp respectively have been designed and construct 然后,本文用兩種自動(dòng)對(duì)焦系統(tǒng)? ?基于pc機(jī)的自動(dòng)對(duì)焦系統(tǒng)和基于dsp的自動(dòng)對(duì)焦系統(tǒng)? ?使數(shù)字成像自動(dòng)對(duì)焦技術(shù)得以實(shí)現(xiàn)。
In order to solve current problems in autofocus field , this dissertation fulfilled some important theoretical studies , such as autofocus theories and methods , focus measures , focus algorithms and focus framing technologies . furthermore , we have designed and construct two autofocus systems based on pc and dsp respectively . funded by the financial aids for cadre college teachers of the education ministry , this dissertation achieved a numbers of outcomes 本文結(jié)合教育部高校骨干教師計(jì)劃“ ccd成像頻譜分析與對(duì)焦算法研究” ,針對(duì)現(xiàn)有對(duì)焦方法存在的問(wèn)題,主要就自動(dòng)對(duì)焦理論與方法、對(duì)焦評(píng)價(jià)函數(shù)及算法、對(duì)焦窗口的智能規(guī)劃等理論問(wèn)題進(jìn)行深入研究,并設(shè)計(jì)制作了基于計(jì)算機(jī)和dsp的自動(dòng)對(duì)焦系統(tǒng)樣機(jī)。
The systems perform the autofocus action with the following steps : analyzing image blurred degree , moving motorized lens , finding best imaging position and finish autofocus . a series of focus experiments have been performed on the above two autofocus systems , their veracity and reliability have probe to be excellent 一系列的對(duì)焦實(shí)驗(yàn)表明,兩種系統(tǒng)對(duì)于透過(guò)玻璃窗的物體以及對(duì)于主要是橫向或縱向柵格狀的物體(百葉窗)均可以準(zhǔn)確對(duì)焦,證實(shí)了我們?cè)O(shè)計(jì)制作的對(duì)焦系統(tǒng)的準(zhǔn)確性和可靠性。
