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,本文用兩種自動對焦系統(tǒng)? ?基于pc機的自動對焦系統(tǒng)和基于dsp的自動對焦系統(tǒng)? ?使數(shù)字成像自動對焦技術得以實現(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 本文結合教育部高校骨干教師計劃“ ccd成像頻譜分析與對焦算法研究” ,針對現(xiàn)有對焦方法存在的問題,主要就自動對焦理論與方法、對焦評價函數(shù)及算法、對焦窗口的智能規(guī)劃等理論問題進行深入研究,并設計制作了基于計算機和dsp的自動對焦系統(tǒng)樣機。
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 一系列的對焦實驗表明,兩種系統(tǒng)對于透過玻璃窗的物體以及對于主要是橫向或縱向柵格狀的物體(百葉窗)均可以準確對焦,證實了我們設計制作的對焦系統(tǒng)的準確性和可靠性。
