The National Stadium in Tokyo was built to host the 1964 Tokyo Olympics.The stadium holds a special place in the hearts of Japanese as a symbol of Japan’s post-World War II recovery. It has hosted sporting events at which the audience witnessed many of the greatest moments in sport history.On 31st May 2014, the curtain was brought down on this half-century old stadium.Our mission was to deepen the bond between the people and the stadium, and to share the fresh start towards the 2020 Tokyo Olympics.

Our system, which creates 3D motion data from old footage, is currently ready for release because we have finished fixing the bugs and refining the interface thanks to a large number of staff. We're now considering presenting papers at academic conferences and releasing an Open Source tool.

This integrated playback system is not designed for versatility. It was customized to the specific requirements of this event, namely for live real-time broadcasting, which means that the number of installable devices and precision are the trade-off. For this reason, this system could not be used for something like a video that requires post-production work; however, linked to broadcasting equipment, the system could be utilized in future television broadcasting.

Many fans took part in the event to bid farewell to the National Stadium, and 3,836 photos were posted to create a commemorative 3D photo.?

We created the last page of the National Stadium’s long history together with the fans who have loved the stadium.

It became an unforgettable event. Besides deepening the bond between the National Stadium and its fans, it also became a kick-start towards the challenge that begins in 2019.
