The invention discloses a vehicle speed matching method based on linear array CCD image, including the following steps that: two linear array CCD video cameras are respectively arranged on two sections positioned on a road at intervals; both linear array CCD video cameras face downwards and are provided with infrared ray laser source; the frame rate of each CCD video camera is more than 1,000 frames per second, and the resolution is more than 1,024 lines; correlation matching computation of the image sequences obtained by both linear array CCD video cameras is carried out to obtain the time difference of the same object in two image sequences; finally, by means of the time difference and the distance between both cameras, the driving speed of an object vehicle can be obtained according to the velocity formula V=s/t.

本发明公开了一种基于线阵CCD图像的车辆速度匹配方法，该方法在道路相距一定距离的两个断面上分别安装两个线阵CCD摄像机，两个线阵CCD摄像机指向垂直向下，线阵CCD摄像机上配有红外线激光源，线阵CCD摄像机的帧速率大于1000帧/秒，分辨率大于1024线；对两个线阵CCD摄像机得到的图像序列进行相关匹配计算，从而获得同一个目标在两个图像序列中的时间差，利用该时间差和两个摄像机的距离，根据速度公式V＝s/t即可以得到目标车辆的行进速度。

This paper use H.264/AVC video transmission, which defines a set of three Profiles. Applications of the Baseline Profile include video telephony, video conferencing; applications of the Main Profile include television broadcasting and video storage; and the Extended Profile may be particularly useful for streaming media applications. H.264 proposes the idea of Network Abstraction Layer. The output of the encoding process of VCL data will be packeted into NAL units. The NAL will give the NAL units corresponding header information according the contents of the units.

而本论文在采用的多媒体压缩技术－H.264/AVC，其定义了三种不同的Profile：Baseline Profile著重在视讯电话，视讯会议等偏重即时传输等服务类别，Main Profile重点则是电视的播放以及影像储存的应用，而Extension Profile则是在串流媒体的播放上提供了较多的技术支援。H.264/AVC并且率先提出了网路提取层的概念，影像在视讯编码层完成编码之后，移交到网路提取层中，而网路提取层会依视讯编码层产生的编码内容将其封装近NAL units，并给予应有的标头资讯。

The embedded video encoder can process A/D transform of video signal, video compressing, network protocol processing and camera controlling. Hence the hardware of encoder includes H.263 Video Encoding Unit and Network Protocol Processing Unit based on TM1300, Network Interface Unit based on RTL8139C chip and Peripheral Extending Unit based on W77E58 which deals with camera controlling.

硬件设计由以下四个单元组成：以 TM1300为核心的视频编码单元和协议处理单元；采用 RTL8139C芯片的网络接口单元；以及单片机 W77E58为核心的完成摄像头控制和透明数据传输的外围扩展单元。

Before taking license plate, the film that Wu Yusen is filming " Chibi " square prevue ever put production in 6 rooms to undertake trying, this is before be based on, 6 rooms roll out " Lin Zhiling knocks gently accept interview " video, accumulative total is close many 800 click a foundation to go up, although a few days short inside " Chibi " acquire the astonishing number that browse on 6 rooms, win many audience support and review, but square angle still is withheld somewhat and hesitate from production, because " Chibi " the beginning that video official net initiated movie industry and video to share a website to cooperate in the line on 6 rooms, there is video website before this with " share interactive " means, cross similar collaboration around the motion picture is big circumjacent open, the consideration of consequence and effect is stemmed from before, the tradition is great production just is general net settle entirely in portal website.

在拿到牌照前，吴宇森正在拍摄的影片《赤壁》制片方的预告片曾放在六间房进行尝试，这是基于之前六间房推出的"林志玲戛纳访谈"视频，累计近800多万次的点击基础上的，虽然短短几天内《赤壁》就在六间房上取得惊人的浏览数，并获得大量观众支持和评论，但从制片方的角度还是有所保留和犹豫的，因为《赤壁》视频官网在六间房上线开创了电影行业和视频分享网站合作的先河，此前没有视频网站以"分享互动"的方式，围绕电影大片的周边开启过类似合作，之前出于影响力和效果的考虑，传统大片制片方全部都是将官网落户在门户网站。
