注册是透明增强现实（AR）系统中的一项关键任务。其重要性不仅源于注册需要仔细校准这一事实，还源于任何校准程序都应考虑到用户的必要性。Tuceryan等人（2002）提出了一种基于虚实点动态对齐的透视装置标定通用方法。虽然是一个强大的工具，但我们的实验表明，用户发现许多点的对齐是压倒性的。我们引入改进以简化校准过程并提高成功率。我们首先确定了为什么校准参数因用户而异，以及如何通过采用跟踪传感器和显示器的特定配置来防止这种情况。这使我们能够重用现有的校准。此外，我们还引入了一个更简单的校准模型，它需要更少的用户输入，通常是四个，来校准系统。
Registration is a crucial task in a see-through augmented reality (AR) system. The importance stems not only from the fact that registration requires careful calibration but also from the necessity that any calibration procedure should take users into account. Tuceryan et al. (2002) proposed a general method for calibrating a see-through device based on dynamic alignment of virtual and real points. Although a powerful tool, our experiments showed that users find alignment of many points overwhelming. We introduce improvements to simplify the calibration process and increase the success rate. We first identified why calibration parameters differ from user to user and how this can be prevented by adopting particular configurations for the tracker sensor and display. This allowed us to re-use the existing calibrations. Furthermore, we have introduced a simpler model for the calibration that requires fewer user inputs, typically four, to calibrate the system.
