point

■ Configure a transparent AR display system with only one holographic film and multiple projectors

■ Realizes a photorial 3D display with high -precision face look measurement data

■ Expectations for use for communication by online through 3D display

　National Research and Development Corporation Information and Communications Research Organization (NICT, President: Hideyuki Tokuda) Digital optical base laboratory applies hologram printing technology (Hoptec), and has 3D display with 3D glasses (naked eye) at the same time.We have developed a transparent AR (Augmented Reality) display system that allows you to experience.This system consists of one holographic film developed by NICT and multiple small projectors.In addition, NICT and Toppan Printing Co., Ltd. (Toppan Printing, President and CEO: Hideharu Maro, Headquarters: Bunkyo -ku, Tokyo), measured in this system using a light stage held by Toppan Print.I succeeded in displaying the 3D video from the 3D.

　In the future, it will be used for online communication and remote work support using a transparent AR display system through photorial 3D display.

background

　In recent years, as the importance of online communication has increased, there are many cases where the amount of information alone is not enough for two -dimensional images, and expectations for photorial 3D display as a communication tool are increasing.

　NICT has been conducting research and development of transparent AR displays that can display images by combining holographic films made using Hoptec and projectors.

　With the Toppan Print, the Toppan Birthal Human Labo, aiming to build a platform that properly processes and provides various information on the human body, including face -to -view data, is the core of the device "Light Stage" that can measure high -precision human body measurements.Opened and developed business.

This result

　NICT has developed a transparent AR display system that allows you to experience 3D display with naked eyes with a simple configuration of holographic film and multiple cheap small projectors.This system projects full -color images using about 30 small projectors, and is viewed in a large number of people without wearing 3D glasses within a diagonal 35 cm, a horizontal viewing angle of 60 degrees, a vertical viewing angle of 10 degrees.It is possible.Regarding light control technology, Kyoto Tachibana University also cooperated.

　In addition, NICT and Toppan Printing are conducting a demonstration experiment to reproduce the face measurement data that contains high -definition and skin texture taken on the Toppan printing light stage in order to explore the potential of new communication by this system.I succeeded in reflecting the natural face expression.

Future prospects

　NICT and Toppan Printing will continue to cooperate with the potential of new communication using 3D content.In addition, utilizing the knowledge and technology that we have cultivated so far, digital twins that connect virtual space and real space, not only entertainment fields such as virtual characters, but also in medical fields such as surgical training and surgery support that display the human body 3D.We will continue to apply to various fields.

　NICT promotes the further high -definition of 3D content, simplification and flexibility of the system, corresponding to various 3D data (for example, CAD data, BIM data, point data, etc.), not to communicate.We aim to develop technologies that can contribute to other fields (for example, construction, education fields, etc.).

　Toppan Printing accumulates various measurement data related to the human body, making use of the management and operation know -how and knowledge under high security, aiming to build a digital content generation platform that can be adapted to various areas.
