在增强现实 (AR) 和混合现实 (MR) 中，测量现实世界中物体的位置和方向非常重要。然而，从图像中识别物体存在很多困难，特别是考虑到实时处理。为了使这种情况下的识别任务变得更容易，通常使用标记。特别是，后向反射器通常用作标记，因为它们在捕获的图像中变得非常明亮并且易于通过图像处理检测到。然而，大多数传统的后向反射器是由玻璃或塑料制成的。因此，很难将它们应用于食品或消化器官内壁检查等领域。在本文中，我们提出了一种由透明食品制成的可食用后向反射器。我们发现寒天或日本琼脂是一种传统的日本烹饪原料，用于形成透明果冻，适合形成这种光学器件。原型机成功地回射了入射光。还提出了由这种可食用后向反射材料制成的可食用基准标记。基于两个原型演示了食品上的动态投影映射，以展示其潜在应用的示例。 (C) 2018 Elsevier Ltd. 保留所有权利。
In Augmented Reality (AR) and Mixed Reality (MR), it is important to measure the position and orientation of objects in the real world. However, there were many difficulties in recognizing objects from images along, especially considering real-time processing. To make the recognition task easier in such cases, markers are commonly utilized. In particular, retroreflectors are often used as markers since they become very bright in captured images and are easy to be detected by image processing. However, most conventional retroreflectors are made from glass or plastic. Thus, it has been difficult to apply them to some fields such as foods or inspection of the inner wall of digestive organs.In this paper, we propose an edible retroreflector made from transparent foodstuff. We found that kanten, or Japanese agar, which is a traditional Japanese cooking ingredient used to form a transparent jelly, was suitable for forming such optical devices. A prototype successfully retroreflected incident light. An edible fiducial marker made of this edible retroreflector material is also proposed. Dynamic projection mapping on food was demonstrated based on two prototypes to show examples of their potential applications. (C) 2018 Elsevier Ltd. All rights reserved.
