而验证码系统被破解倒也未尝不是一件好事，因为这标志着机器视觉取得突破，或许，自动书刊扫描系统将由此变得远比现在精准。

But if CAPTCHAs are broken it might not be a bad thing, because it would signal a breakthrough in machine vision that would, for example, make automated book-scanners far more accurate.

在系统实现过程中，针对户外环境，采用基于标志点的注册算法实现系统的三维注册，最后通过实验效果验证了算法的正确性。

During the realization of the prototype, for the Outdoor environment, marker of points in 3d registration is adopted, and the correctness of this algorithm is confirmed by realizing it in system.
