Vicon to Preview Vicon iQ at SIGGRAPH(August 06, 2001)
Until now, motion capture data has been processed in a series of steps, from detection of markers by the cameras through to application of the 3D data to a character model. An error in any one of these steps is carried on to the subsequent steps unless detected and corrected manually. To assist with this labor intensive process, motion-capture manufacturers and third-party software suppliers have provided tools for manually or semi-automatically editing inaccurate results.
'Vicon iQ is the single biggest step in motion capture data processing for many years,' said Pete Meddings, Vicon Managing Director. 'We have unified the separate stages of the process to create an intelligent, holistic software application that provides far greater accuracy and efficiency from capture to animation.'
Vicon iQ's intelligence is based upon keeping all the captured data intact throughout the process, and automatically referring to it if ambiguities arise. By contrast, the current generation of motion capture software products discard information at each stage once a result has been achieved. When errors are encountered in later stages of the process, the discarded data is no longer available as a resource, and the operator is forced to make manual interpretations and corrections.
Vicon iQ employs continual feedback loops to deliver correct results even in challenging situations. If an ambiguity arises at any point, data from earlier or later in the process is automatically referenced to find the best solution for the complete capture.
As an example, a common problem in conventional capture occurs when two or more performers come into close proximity and the system confuses markers between the performers. In this situation, Vicon iQ carries multiple possible solutions to the trajectories of markers and loops back and forward through the capture data to points where the marker assignment is clear, using this reference to intelligently interpret the correct trajectories.
Vicon iQ applies this type of intelligence from the beginning of the data processing, right through to the point of fitting and even re-targeting data to the character or characters. One piece of software now unifies the entire process and provides the solution to highly-accurate motion capture with an efficient workflow. 'Keeping all the data throughout the process means that manual clean-up is almost completely removed from the motion capture process,' said Vicon's Director of Research Geoff Shaw. 'Ensuring perfect correspondence between the data and the finished animation will be much easier now, and the productivity gains offered by Vicon iQ are enormous.'
Vicon 8i is the most advanced optical motion capture system available and allows actors to move freely, unrestricted by wires, awkward suits or large body markers. The system can capture multiple actors simultaneously, and with Vicon's million-pixel resolution MCam, motion data is recorded at near perfect accuracy. Vicon 8 is the same professional motion capture solution that has been used in the production of leading game and feature film projects including, 'Gladiator', 'Star Wars Episode 1: The Phantom Menace', 'The Mummy', 'The Patriot', 'Titanic', and many others.
