By analyzing the design principle , the paper devised an image source signal alternated with black and white strip and it has a good effect . meanwhile , the system demand of imaging link was analyzed , such as light source , lens and camera etc . in addition , the principles of both the correlation algorithm and generalized correlation time delay estimation based on adaptive technology were studied , and a comparison between them was made as well 本文中分析了图像源信号的设计原则,并设计了一种黑白相间的倾斜条纹图案作为图像源信号,获得了良好的测量效果;分析了测量系统对光源、镜头、相机等成像环节的要求;研究了相关算法和基于自适应技术的广义相关时延估计法两种数据处理算法的原理,并对两种方法的性能进行了比较。
What it was , whether beast or human being , one could not , at first sight , tell : it grovelled , seemingly , on all fours ; it snatched and growled like some strange wild animal : but it was covered with clothing , and a quantity of dark , grizzled hair , wild as a mane , hid its head and face 在房间另一头的暗影里，一个人影在前后跑动，那究竟是什么，是动物还是人，粗粗一看难以辨认。它好象四肢着地趴着，又是抓又是叫，活象某种奇异的野生动物，只不过有衣服蔽体罢了。一头黑白相间乱如鬃毛的头发遮去了她的头和脸。
