图形增强现实（AR）标记的设计需要在美学外观和跟踪可靠性之间进行权衡。为了研究这一课题，我们创建了一个虚拟现实（VR）流程来评估标记的性能，并针对一组图形AR标记根据实际性能对其进行了验证。我们报告称，使用著名的Vuforia框架和典型的智能手机硬件，设计良好的20×20厘米标记在距离达68厘米时仍可被跟踪。我们注意到，特征点的数量对标记的角度性能尤为重要。
The design of graphical augmented reality (AR) markers requires compromise between the aesthetic appearance and tracking reliability. To investigate the topic, we created a virtual reality (VR) pipeline to evaluate marker performance, and validated it against real-world performance for a set of graphical AR markers. We report that, with the well known Vuforia framework and typical smartphone hardware, well designed 20 × 20 cm markers can be tracked at distances of up to 68 cm. We note that the number of feature points is particularly important to a marker’s angular performance.
