A permanent projection mapping installation was set up at the Dockyard Garden, in front of the Yokohama Landmark Tower. The show was automated and played every day. Due to the irregular nature of the projected wall, a color compensation process was developed: the projection area was scanned using a light pattern and cameras, generating an updated wall template that could then be used by the projection mapping system. For maintenance, the process could be launched remotely at any time. My work focused on the development of this color compensation system.
