攝像頭的工作原理大致為:景物通過鏡頭(LENS)生成的光學(xué)圖像投射到圖像傳感器表面上,然后轉(zhuǎn)為電信號,經(jīng)過A/D(模數(shù)轉(zhuǎn)換)轉(zhuǎn)換后變?yōu)閿?shù)字圖像信號,再送到數(shù)字信號處理芯片(DSP)中加工處理,再通過USB接口傳輸?shù)诫娔X中處理,通過顯示器就可以看到圖像了。

針對視頻監(jiān)控中攝像機鏡頭光圈大小、圖像聚焦、圖像變焦三項參數(shù)的控制問題,介紹了一種基于89C51單片機的鏡頭控制電路的設(shè)計。 該電路以89C51單片機為核心,結(jié)構(gòu)簡單,成本低廉,控制可靠,實現(xiàn)了智能監(jiān)控終端對攝像參數(shù)的完全控制。 Abstract: The design of camera LENS control circuit based on 89C51 is introduced. This circuit can adjust parameters of camera such as aperture, zoom and focusing. The practice of project shows that this circuit has advantages of structure simple, low cost and high reliability.

卡耐基.梅隆大學(xué)的牛發(fā)寫的關(guān)于孤立點和數(shù)據(jù)清洗的文章,全英文,2003年完成,Probabilistic Noise Identification and Data Cleaning,Real world data is never as perfect as we would like it to be and can often suffer from corruptions that may impact interpretations of the data, models created from the data, and decisions made based on the data. One approach to this problem is to identify and remove records that contain corruptions. Unfortunately, if only certain fields in a record have been corrupted then usable, uncorrupted data will be lost. In this paper we present LENS, an approach for identifying corrupted fields and using the remaining noncorrupted fields for subsequent modeling and analysis.

1-1單透鏡這個例子是學(xué)習(xí)如何在ZEMAX里鍵入資料,包括設(shè)置系統(tǒng)孔徑(System Aperture)、透鏡單位(LENS Units)、以及波長范圍(Wavelength Range),并且進行優(yōu)化。你也將使用到光線扇形圖(Ray Fan Plots)、彌散斑(Spot Diagrams)以及其它的分析工具來評估系統(tǒng)性能。這例子是一個焦距100mm、F/4的單透鏡鏡頭,材料為BK7,并且使用軸上(On-Axis)的可見光進行分析。首先在運行系統(tǒng)中開啟ZEMAX,默認的編輯視窗為透鏡資料編輯器(LENS Data Editor,LDE),在LDE可鍵入大多數(shù)的透鏡參數(shù),這些設(shè)置的參數(shù)包括:·表面類型(Surf:Type)如標準球面、非球面、衍射光柵..等·曲率半徑(Radius of Curvature)·表面厚度(Thickness):與下一個表面之間的距離·材料類型(Glass)如玻璃、空氣、塑膠.…等:與下一個表面之間的材料
