扫描码

Well, it could be that you have a huge collection of ISBN numbers, and that there are so many of them that for weird reasons some have the wrong check digit perhaps the numbers were scanned from a printed list and the OCR got the numbers wrong, perhaps the numbers were manually captured...

因为你可能有数量巨大的 ISBN 的编码，而其中又有大量的编码不知道什么原因，校验码是错的（可能是编码是从一个打印出来的列表里头扫描并 OCR 出来的，编码就错了，也可能是编码被手工捕获的。。。

In this paper, Gray code and line shifting structure light were projected to the object. Then the distortion images were got which can reconstruct the 3D model: The images space was divvied into 64 cycles by six sequence image the acquisition, the whole scanning plane has been covered by the mobile fringes, which has been cycled 20 times. With the parameters of two calibration cameras , the image pixels has been matched by the principle of geometry.

本论文的主要研究内容是利用格雷码加线移结构光对物体进行投影，再经摄像机采集到畸变的图像，结合相关算法以实现对物体的三维重构：摄像机采集到的6幅图像序列形成的格雷码将图像空间划分为64个周期，通过20次线条纹的移动完成对整个扫描平面的覆盖，在已获得两摄像机标定参数基础上，结合对极几何原理完成左右图像像素点的匹配。

Furthermore, the pairwise transient key is computed in advance and message integrity code is piggybacked in probing massages, which satisfies desirable security attributes and reduces the re-authentication delay.
