为了详细了解放射性工作环境中的辐射信息，如剂量率和放射性物质的位置，作者提出了构建环境的镜像世界。在所提出的镜像世界中，工作环境被再现在虚拟空间中，并且在真实的空间中测量的辐射信息被投影到虚拟空间上。注意，除了在虚拟空间中显示放射线信息之外，虚拟空间中的放射线信息的可视化结果还用于真实的空间中的决策。本文介绍了一个利用137Cs作为辐射源，在实验室进行辐射测量的基础上建立镜像世界的例子。在实验室中，使用测量仪以及基于三维（3D）光探测和测距的同时定位和绘图设备来测量剂量率。测量的剂量率被映射到虚拟空间中的工作环境。此外，还使用了Compton照相机与运动恢复结构技术相结合的放射源3D可视化技术、显示放射源图像的工作环境的虚拟现实体验技术等作者开发的技术。介绍了利用增强现实技术将辐射源图像投影到真实的空间的技术。可以看出，在真实的空间中的辐射测量和在虚拟空间中的测量结果的可视化总是影响彼此空间中的工作的决策。
To understand radiation information, such as dose rate and the position of radioactive substances in a radioactive working environment in detail, the author proposes the construction of a mirror world of the environment. In the proposed mirror world, the work environment is reproduced in a virtual space, and the radiation information measured in a real space is projected onto the virtual space. Note that in addition to displaying the radiation information in the virtual space, the visualization result of the radiation information in the virtual space is used for decision-making in the real space. In this paper, the author introduces an example of building the mirror world based on radiation measurements performed in a laboratory using 137Cs as a radiation source. In the laboratory, the dose rate was measured using a survey meter together with a device for the simultaneous localization and mapping based on three-dimensional (3D) light detection and ranging. The measured dose rate was mapped onto the work environment in the virtual space. Technologies developed by the author, for example, the 3D visualization of the radiation source based on an integration of the Compton camera and structure-from-motion technology and the virtual-reality experience technology of the work environment that displays the source image were also used. The technology to project the radiation-source image into the real space using augmented-reality was also introduced. It is seen that radiation measurement in the real space and visualization of measurement results in the virtual space always affect the decision-making of work in each other's space.
