Abstract—Structured light
successfully used for accurate measurement
computer vision. However, their applications are mainly limited be captured for recovering one 3D scene. This paper presents an coded vision system. To achieve 3D measurement for a dynamic scene, the data acquisition must be performed with only a single image. A principle of uniquely color-encoded pattern projection is proposed to design a color matrix for improving the reconstruction efficiency. The matrix is produced by a special code sequence and a number of state transitions. A color projector is controlled by a computer to generate the desired color patterns in the scene. The unique indexing of the light
projection since it is essential that each light grid
identified by incorporating local
reconstruction can be performed
single image.A scheme is presented to describe such a vision processing method for fast 3D data acquisition. Practical experimental performance is provided to analyze the efficiency of the proposed methods.

II.C ONCLUSION
Real-time, low-cost, reliable, and accurate 3D data acquisition is a dream for us in the vision community. While the available technology is still not able to reach all these features together, this paper makes a significant progress to the goal. An idea was
for generating a specially
combines the advantages of both fast 3D vision processing from a single image and reliability and accuracy from the principle of structured light systems. With a given set of color primitives, the patterns generated are guaranteed to be a large matrix and desired shape with the restriction that each word in the pattern matrix must be unique.
the method does not have a limit in the smoothness of object surfaces since it only
and identifies the coordinates by local image processing, which greatly improves
efficiency. Theoretical analysis and
mid-level resolution takes about 100 ms which is adequate for many practical applications. Some software and hardware skills may be applied to further improve the speed to above 30 frames per second (fps). A parallel processing scheme will further increases the efficiency several times.

英语六级写作三个套路 作文的展开—按照三步走： 1)题目涉及的现象进行简单的描述，在描述的过程中将写作引向文章的主题(这样的描述可以自己控制，如果第一段落字数单薄，可以适当使描述具体化)。 2)在第一步的基础上给出观点，观点视文章主旨可以分为：个人观点(包括方法、途径)，和多方观点(观点从正反两方面或者一个方面的多个层次阐述；在交待观点是需要有原因和支持)。 3)个人观点总结点题(同意异表)，简要指出方法途径，如果找不到具体的解决方法，则将话讲得圆滑(如果正文中间观点没有必然冲突，则可以融合)。 例子： A 1995.1 my view on the negative effects of some advertisements 社会上的广告现象越来越多，很多的广告对我们的社会有不良的影响-〉(广告如何

高考英语作文之概要写作五篇及答案全套 一 My wife has watched me write, blog and make speeches for a few years now. I’ve encouraged her to do her own video blog (vlog), too, because she is always watching them, but she hasn’t been interested in the spotlight. Now that enough time has passed, she is ready to go for it! Angelika is a great cook, so she is going to do a cooking show where she doesn’t have to be on camera. I am just thrilled that she has found a passion to pursue in a way that works for her. I’m smart enough to step back and let her go at her own pace (节奏). I know that being there for emotional support or however she needs me is important. Now that my wife will have a studio worthy of her talents and personality, she will only make the kitchen look better. Part of me hopes that I will spend the rest of my life watching and tasting her creations. When you start to express your creative drive, it can be a wonderful ride, a bit of a roller coaster at times, but worth the price of admission. When the love of your life takes the ride with you, and starts to drive, it’s a pretty cool way to travel through life. I am at my best when being creative, whether in front of a keyboard or a live audience. I have always encouraged creative answers to life. There is always more than one right way to do something.
英语写作三原则 原则一：逻辑语义关系标示语的使用 句子间或段落间的命题之间的语义联系可以通过逻辑关系标示词直接连接起来，以显性的语言成分形式出现于篇章表层；这就是所谓的语篇逻辑语义的“显明性” (explic itness)。但在有的情况下，或是因为信息本身的逻辑关系非常清楚，或是因为情景语境已经提供了必要的启示，即使没有连接性词语，句子与句子或段落与段落之间的逻辑关系也可以通过隐性的衔接手段连接起来；语篇逻辑语义的这种特征被称为语篇逻辑语义的“隐含性”(implicitness)。连接是指用连词、副词或词组（短语）等逻辑关系标示语把两个命题联系起来的手段,可用来表示两个小句之间的逻辑语义关系。绝大多数的语言研究者认为英汉语篇逻辑语义的确存在显性或隐性的差异。如朱永生（2001：102）认为，与其他所有衔接手段相比，连接是英汉两种语言之间差别最大的一种衔接手段；再如，连淑能（1992）认为，由于汉语注重意合，在汉语的语篇中，隐性的连接成分是相当常见的，是读者或听话者很容易接受和理解的一种语言现象。而英语注重形合，英语中语篇连接成分在绝大多数的情况下是显性的。因此，这种“显明性”和“隐含性”在一定程度上反映了英汉两种思维方式的差异和这种差异所造成的英汉两种语言在语言表达上的差异。在英语写作学习过程中，中国学生由于受汉语隐性连接传统方式的影响，在两个命题之间常常不使用逻辑语义关系标示语，有时甚至因为理解问题而误用逻辑语义关系标示语，因而造成逻辑关系表达不清的问题。 在英语写作具体行文过程中，连接或表示语篇中不同命题之间逻辑语义关系的成分就是我们所谓的逻辑关系标示语。它们往往是一些常见的小词。比如说，“and”一般被用来表示并列或递进关系；“but, however, yet, nevertheless”等一般被用来表示转折关系；但是值得注意的是，越是常见的词，就往往越为学生所忽视；加上受汉语逻辑语义“隐含性”特征的影响，中国学生在学习英语写作时极易出现逻辑关系标示语的误用甚至于不用。因此，在英语写作过程中，我们应当着重培养自己对这些标示语的敏感性。 原则二：照应标示语的使用 照应（anaphora）又称前指。从广义上来说，它指的是语言表达中一个词或短语在语篇中被用来（回）指同一语篇中另一个词或短语的语言现象。前者一般被称为前指词（anaphor），后者一般被称为先行词（antecedent）。两者之间是一种语义上的共指（co-reference）关系。这种共指关系可以出现在同一句、同一段落或同一篇章中，是篇章连贯的主要手段之一，因而近几十年来一直是语言学、心理学、人工智能、语言教学等学科的研究对象。根据先行词与前指词之间的关系及其词法和句法特点，照应关系可以分为三大类：句际照应、动词性照应和名词性照应，分别如下例所示（划线部分分别为先行词和前指词）： （1）John told me that he could finish the test in half an hour, but I wouldn’t b elieve it. （2） a. He went to the part yesterday. So did his wife. b. Perry bought a blue jacket, and Tom ? a black one. （3）John bought a red car and Paul bought a white one. 在这里，我们所说的照应标示语（又称指称词语）指的是名词性照应，它包括所有名词性的词语，如代词、名词等。照应标示语之所以能够成为保持语篇逻辑语义关系的重要手段之一是因为其指称性。苏东坡诗曰：“横看成岭侧成峰，远近高低各不同。不识庐山真面目，只

初一英语作文三篇 English is one of the most important subjects in middle school。 Almost everyone knows that we should learn English well， but few of us know how to learn it well。 Karl Marx has set a good example for us。 He once said， "When one is learning a foreign language， he must use the foreign language。" In this way， he could use several languages。 A saying goes， "Practice makes perfect。" When we learn English， we should read more， speak more， listen to English from time to time and practise writing every day。Don"t be afraid of making mistakes。 Only in this way can we learn it well。 English is widely used throughout the world。 So many people speak it as a second language。 n line， you"ll find lots of information in English。 If you don"t understand English， how can you know more about the world， how can you get more knowledge。 At international conferences，English is also used as the official language。 Without good English， you cannot express your ideas well at such conferences， neither can you introduce China to the outside world。
