数字化

Now let's return to the subject of sending this new digital message to space.

现在让我们回到这个向宇宙发送数字化信息的话题来吧。

Compared with the conventional 2-D coordinate measuring systems, the new system has great improvement at measuring speed, aiming accuracy, measuring function and degree of automation The new system consists of two parts image measuring system of displacement and image autofocusing and aiming system The displacement measuring system in which CCD camera is used for locating the optical scale not only processes the advantages of absolute code measuring system powerful noiseproof feature, good long-time stability, easily compensated ruling error of optical scale, but also has the advantages of morden numerical systems easy numeralization and intelligence The autofocusing and aiming system in which CCD camera is applied for gaining the defocusing information and edge location information of workpiece enjoys the advantages of fast autofocusing, accurate result, high accuracy of edge detection and wide range of measured parameters, etc The feasibility of the new 2-D measuring system is analyzed in this thesis and related parameters are calculated.

详细本文在分析了现有二维中小尺寸测量系统中，光学仪器的光学读数系统和调焦、瞄准系统的优缺点之后，结合现代数字化仪器的优缺点，提出研制一种新的二维图像测量机系统。与传统二维坐标测量系统相比，新型系统在测量速度、瞄准精度、测量功能及自动化程度等方面都有较大的提高。该系统由图像式位移测量系统和图像式自动调焦、瞄准系统组成。图像式位移测量系统采用CCD摄象机拾取光学线纹尺的位置信息，既具有传统光学式绝对码位移测量系统的优点—抗干扰能力强、长期稳定性好、光学标尺误差易于补偿等优点，又具有现代化数字仪器易于微机化、智能化的优点。

The few word processing module from AT89S52, TVIA5715, the SAA7113 constitution, first the video semaphore digitize, then the conversion becomes the RGB semaphore output of the non-interlaced.

Firstly, the paper analyzed the characteristics of movie video's digitization from the angle of movie noumenon.

首先，从电影本体的角度分析数字时代电影影像的数字化特点。

Such is the case of the NYT, Atlantic Monthly, Guardian and many others.

这些年来，我们已经看到了大报纸扫描和数字化的许多历史档案，有时甚至允许充分利用非

Objective: To observe the influence of the trial point on the quality of root canal obturation .

目的 ：利用计算机数字化图像系统能储存大量图像的特点，了解试尖对侧向加压法根管充填质量的影响。

The image collecting parts mainly complete the conversion of the optics photograph to the image that can be treated by the computer. In this step, the pictures of teeth are shot by CCD and store in the compute at the aid of the video collecting cards. The image processing parts realize the geometric transformation, color adjusting, enhancement, measurement and some specially good effects of the collected images. And at the assist of the image processing, the more image information of dental images is exploited, so that the odontologist can diagnose more accurately.

牙科图像数字化主要完成从光学图像到计算机可处理图像的转换，为系统提供可操作的对象，其基本过程可描述为：通过CCD摄像镜头，对实物进行拍摄，由视频采集卡以信息流的形式对信号实时采集、捕捉，以帧的形式缓存，以静态的图像格式存储在计算机中；牙科图像处理部分不仅实现了图像的几何变换、色彩调整、图像增强以及一些特效，而且对牙齿病变部位进行测量，通过这些操作，能够获得更多的图像信息，提高了医生对病情诊断的科学性；牙科病例数据库部分能够浏览病人的基本信息及牙科图片，实现患者病历的添加、删除、修改等操作，建立患者牙科图像档案的图文数据库。

One of the ways to solve the problem above is actualizing the digital corresponding, transforming the image to the digital signals, wiping off the redundancy outlying of the image quality. Furthermore, on the precondition of ensuring the quality, storaging, recording and transmitting the digital signals is oecumenical, credible and all wool and a yard wide using least bits or bits ratio.

解决这个问题的途径之一，是实现图像通信的数字化，把图像信息转换成数字信号，去除与图像质量无关的冗余信息，并且在保证质量的前提下，用最少量的数码或数码率，实现各类图像的数字存储、数字记录或数字传输，达到优质、可靠、经济的要求。

With development of Internet tech n ology, the network has gradually penetrated into the people's lives in all areas. Information management system of digital and network technology has become an inevitable trend.

随着Internet技术的发展，网络已经逐步渗透到人们生活的各个方面，各种信息管理系统的数字化、网络化已成为必然趋势。

To some problems of it, the design train of thought that only A/D, subdivision and counting circuit compose open-loop control system is proposed in this paper. It thoroughly renovates traditional design train of thought; Integrated subdivision circuit on the basis of AD2S90 and QA740210 is proposed and designed; Digital readout system has simple PLC function and realizes communication between it and PC; Advanced LCD technology is adopted; Using software error amendment realize dynamic compensation for error; Intelligence digital readout system by inductosyn having high accuracy and multifunction is designed.

针对目前感应同步器数显表存在的一些问题，本论文研究中提出了仅有A/D转换、细分和计数电路组成的开环控制系统的设计思路，彻底革新了传统的设计思路；提出并设计了基于AD2S90和QA740210的集成化细分电路；使数显表具有了简易PLC的功能，实现了上位机PC和数显表之间的通讯；采用了先进的LCD液晶显示技术；利用软件误差修正方法可以实现对误差的动态补偿；开发设计了精度高、功能多的智能数字化感应同步器数显表。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
