论文摘要
现有的方法嵌入3D对象内的不引人注目的标签需要复杂的制造或高成本成像设备。我们提出了红外传说，它们是肉眼不可察觉的2D标记和条形码，可以将3D打印为物体的一部分，并通过低成本近红外摄像头迅速检测到。我们通过从红外传输丝中打印对象来实现这一目标，红外摄像头可以看到，并在内部有空气间隙以用于标签的位，后者在红外图像中以不同的强度出现。 我们构建了一个用户界面，该界面促进了将通用标签（QR码，Aruco标记）与对象几何形状的集成，以使其3D可打印为红外数据。我们还开发了一个低成本的红外成像模块，该模块使用我们的图像处理管道增强现有的移动设备和解码标签。我们的评估表明，可以在很少的近红外照明（0.2lux）和距离为250厘米的情况下检测到标签。我们演示了我们的方法如何启用各种应用程序，例如对象跟踪和嵌入元数据以增强现实和切实的相互作用。
Existing approaches for embedding unobtrusive tags inside 3D objects require either complex fabrication or high-cost imaging equipment. We present InfraredTags, which are 2D markers and barcodes imperceptible to the naked eye that can be 3D printed as part of objects, and detected rapidly by low-cost near-infrared cameras. We achieve this by printing objects from an infrared-transmitting filament, which infrared cameras can see through, and by having air gaps inside for the tag's bits, which appear at a different intensity in the infrared image. We built a user interface that facilitates the integration of common tags (QR codes, ArUco markers) with the object geometry to make them 3D printable as InfraredTags. We also developed a low-cost infrared imaging module that augments existing mobile devices and decodes tags using our image processing pipeline. Our evaluation shows that the tags can be detected with little near-infrared illumination (0.2lux) and from distances as far as 250cm. We demonstrate how our method enables various applications, such as object tracking and embedding metadata for augmented reality and tangible interactions.
