2 Cultural Heritage Structure Definition Identification of needs ICT Definition The role of CIPA-HD Contribution of ICT Data acquisition Processing software Alternative products Future outlook
3 Cultural Heritage Implies the monuments, but also every kind of document or evidence of civilization Carrier of historic memory and ark of national and global civilization. Tangible and Intangible Cultural Heritage.
4 Cultural Heritage Tangible Intangible ideas - traditions poetry literature - songs monuments dances performances - customs handicraft artifacts
5 Cultural Heritage is in need of Documentation (Geometric, Architectural, Historic etc.) 2D/3D for archiving, studies, planning etc. Accuracy/accurate measurements (for restoration, reconstructions, structural studies, protection etc.) Monitoring of its state Proper Management of its data (for sustainability, risk management etc.) Preservation possibilities (e.g. digital libraries etc.) Public Outreach (visualization, dissemination, awareness of the public )
6 Protection of Cultural Heritage Obligation of all generations for the preservation of historic memory International Conventions (Venice Charter, Granada Convention etc.) International Organizations for the protection of Cultural Heritage UNESCO ICOMOS (National ICOMOS Chapters) CIPA Heritage Documentation (with ISPRS)
7 International Cooperation ICOMOS 1964
8 The role of CIPA HD Encourage and promote development of principles and good practices for recording, documentation and information management of cultural heritage Lead and participate in international training programs for conservation and informatics professionals, students and site personnel; Advise government bodies, regional authorities, non-profit groups and institutions on tools, technology and methods for using technology; Promote an international network of professionals in both the fields of technology and cultural heritage for scientific research but also applied practical experience; Provide a platform with the bi-annual International Symposium for the exchange of ideas, best practices as well as scientific research papers. Become members and participate!!!

18 Motion capture systems Video Mocap data Dance recording using an HD camera. Data saved in MP4 (MPEG-4 C3D - stored part 3D 10 coordinate H.264) or information, analog FLV (flash) format data and associated information Actor as it data is recorded from the motion FBX capture the system. motion of the performer is saved as an actor. Any virtual character Character data (avatar) can be incorporated FBX to perform A virtual the character has been dance incorporated to the actor. Dr A. Aristidou, University of Cyprus
