在本文中，我们介绍了傅立叶标签，这是一种合成基准标记，用于视觉编码信息并提供可控定位。傅立叶标签是类似于条形码的合成目标，它指定可以在图像中高效且可靠地检测的多位信息。此外，傅里叶标签具有一个有益的特性，即它编码的位串具有作为相机和目标之间的距离的函数的可变长度。这是因为有效分辨率会因视角的影响而降低。本文介绍了傅里叶标签，描述了其设计，并通过实验说明了其特性。
In this paper we introduce the Fourier tag, a synthetic fiducial marker used to visually encode information and provide controllable positioning. The Fourier tag is a synthetic target akin to a bar-code that specifies multi-bit information which can be efficiently and robustly detected in an image. Moreover, the Fourier tag has the beneficial property that the bit string it encodes has variable length as a function of the distance between the camera and the target. This follows from the fact that the effective resolution decreases as an effect of perspective. This paper introduces the Fourier tag, describes its design, and illustrates its properties experimentally.
