本文介绍了一种基于摄像机的光学透明眼镜（STG）的标定方法。为了克服参数模型的缺点，引入了一种新的校准技术来校准STG的每个单个显示像素。与参数模型相比，非参数模型的优点在于它还可以映射任意失真。使用基于波导的显示器[5]的新一代STG由于其光学特性将具有更高的任意失真。第一次测试显示比以前的作品更好的精度。通过使用放置在STG的显示器后面的相机，不需要容易出错的用户交互。结果表明，一个高精度的跟踪设备是没有必要的良好的校准。刚性安装在STG上的摄像机用于找到系统组件之间的关系。此外，这项工作阐述了第二个后续校准步骤的必要性，该步骤使STG适应特定用户。第一次测试证明了这一后续步骤是必要的理论。
This work describes a camera-based method for the calibration of optical See-Through Glasses (STGs). A new calibration technique is introduced for calibrating every single display pixel of the STGs in order to overcome the disadvantages of a parametric model. A non-parametric model compared to the parametric one has the advantage that it can also map arbitrary distortions. The new generation of STGs using waveguide-based displays [5] will have higher arbitrary distortions due to the characteristics of their optics. First tests show better accuracies than in previous works. By using cameras which are placed behind the displays of the STGs, no error prone user interaction is necessary. It is shown that a high accuracy tracking device is not necessary for a good calibration. A camera mounted rigidly on the STGs is used to find the relations between the system components. Furthermore, this work elaborates on the necessity of a second subsequent calibration step which adapts the STGs to a specific user. First tests prove the theory that this subsequent step is necessary.
