Now,mostly research is to find a simple,timeless and exacted arithmetic for practical application.

目前，摄像机标定技术的主要研究任务在于根据实际应用的特点，寻找简便、快捷、准确的标定算法。

Vidicon collect simulate image in period of time and send to computer or DSP chip through video collection card digitlization,use computer to gain eyewinker and process digital image processing:using image area segment and boder measure to calculate area and perimeter;using image smoothness to wipp offthe infection of yawp;using dynamic background and image suited technology to overcome the infection of ray;calculation the parameter of eyewinker(area, perimeter,round measurement, proportion characer and invariant monent),using least norm to design the linearity classify parts,using image matching technologyto classify eyewinker,and to judge whether the eyewinker is harmful to diff background,if the eyewinker satisfy the character require of harmful object ,system will auto-stsrt alarm device. If there ia not have found any eyewinker, Vidicon will collect new simulate image and make processing.

本设计是将摄像机或高频头采集到的模拟图像经过视频采集卡数字化后送入计算机或DSP芯片，利用计算机对采集到的一定时间段内的图像进行异物获取，并对异物图像进行数字图像处理：利用图像区域分割和边缘检测以便进行面积和周长的计算，利用图像平滑去除噪声的影响，利用动态背景运动检测法和图像配准技术克服光线的影响，并通过异物的各类参数（如面积、周长、圆形度、比例特征和不变矩等）的计算，采用最小范数分类法设计了线性分类器，利用图像匹配技术对异物进行分类，从而判断异物是否有害，针对于不同的背景，若异物满足有害物体的特征要求，则认为物体有害，自动启动报警装置，如果没有发现有害异物则新摄入的图像将取代前一时间段的图像再进行图像处理。

For instance, he stumbled upon the "fade-out" when the iris on his camera malfuctioned.

例如，当他的摄像机光圈出现故障时，他偶然发现了"淡出"）。

To improve the imaging quality of CCD camera and make the lens small in size,compact in structure,the wide field of view optical lens with the standard quadric surface and even aspheric surface was designed.

为提高CCD摄像机的成像质量，同时使镜头结构紧凑、小型化，在大视场光学镜头的设计中，引入标准二次曲面和偶次非球面。

The depth of field of a lens is its ability to keep in focus objects of varying heights or objects located at various distances from the camera.

一个镜头之景深使其能够于不同高度目标物或目标物处于由摄像机不同距离时保持在焦。

To select six athletes who enter the male chia-group high-jump finals as my research object in the youth track and field events of Jiangsu province. To use two JVC9800 high-speed cameras took synchronism image in l00fps and analyzed the images in the SIMI-motion video analytical system.

WuJian who won the silver in the third youthful world championship of track and field events is selected as my research object.The synchronism images were taken by two JVC9800 high-speed cameras in 200fps and analyzed by the SIMI-motion video analytical system.

选定江苏省青少年男子铁饼运动员吴健为研究对象(第3届世界少年田径锦标赛掷铁饼银牌获得者)，采用两台JVC9800高速摄像机以200fbs的速度同步拍摄，并采用SIMI-motion录像解析系统进行图象解析。

I hope one day I can carry on the shoulder an own camera, taking my play set, the personnel struggles together in the filmdom!

我希望有一天我能扛着自己的摄像机，带着我的剧组人员一起奋斗在电影界！

Our Sentinel system consists of a computer-controlled camera, fisheye lens and digital video recorder.

库克说：我们的'哨兵'系统由一台电脑控制的摄像机，鱼眼镜头和数字视频记录器构成。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
