Towards an Affordable Markerless Acquisition of Intangible Contemporary Dance Choreographies at Large-Scaled Stages

While the documentation and preservation of rigid cultural heritage objects has become much easier with technologies such as 3D scanning or photogrammetry technologies, the digitalization of 3D intangible moving content is still a major issue. This concerns also the in situ creation of digital dance representations and the question of how to preserve and disseminate dance performances. In this paper, we present a generic and affordable approach for an automatized and markerless capturing of the movements of dancers, which was developed in the Motion Bank research project, as well as first application examples which analyse and visualize the captured dance data. The captured data is stored in a cloud based service and is thus made available for online and offline processing.
