为了在增强现实系统中通过计算机通过相机图像来利用现实世界，必须识别系统的简明坐标信息。基于图像的方法对此很有希望，因为它们提供从相机图像到虚拟对象坐标系的直接映射，因此不需要相机校准。然而，传统的基于图像的标记通常是贴纸，它们传递的信息是有限的并且容易动态变化。在本文中，我们提出了一种位置标记方法，称为VCC（视觉计算机通信），它使用更智能的标记。在我们的方法中，由 16 个 LED（发光二极管）组成的标记不断闪烁，以提供坐标信息和附加信息，例如地址或 URL。
In order to utilize the real world via computers by means of camera images in augmented reality systems, the concise coordinate information of the systems must be identified. Image-based approaches are promising for this purpose since they provide direct mapping from the camera images to the coordinate system for virtual objects, and therefore, no camera calibration is necessary. However, the conventional image-based markers are typically stickers, and the information they deliver is limited and susceptible to change dynamically. In this paper, we propose a location marking method, called VCC (visual computer communication), which uses more intelligent markers. In our method, a marker, consisting of 16 LEDs (light-emitting diodes), keeps blinking to provide both coordinate information and attached information such as an address or a URL.
