Sports physicians' meeting: 3D motion analysis in skiing
In December 2005, the sports physician' meeting
(Sportärztewoche) took place in Zell am See.
CONTEMPLAS presented the use of video-based motion analysis in
alpine skiing to the participants.

There was no cloud in the sky, when Prof. Dr. Gert-Peter Brüggemann (German
Sports University in Cologne) and Stefan Klippel, CONTEMPLAS CEO, shouldered
their backpacks on Sunday, 4th of December.
They carried the equipment for a 3D motion analysis to the glacier
of the Kitzsteinhorn, up to an altitude of 3000m.

The conditions on the piste were really excellent and they installed two digital
cameras, covering a volume of approx. 2m x 2m x 2m, and connected them to
a notebook via 20 m firewire cables.
The cameras had to be accurately calibrated so that the video capture of
the skiers could be carried out. One camera was installed laterally to the gate
and the other from a frontal perspective. They prepared a giant slalom on the slope
and the analysis was carried out for a right turn in the middle of the race course.
Temperatures of -10° Celsius and heavy gusts of wind made great demands on team
and equipment.
The head of the ski school in Kaprun and some of his skiing instructors had
agreed to be analysed. At the same day, the skiing instructor’s motion sequence
of the giant slalom was analysed and reconstructed in 3D.

It was a great pleasure to organise this event with Prof. Brüggemann and the local
ski school and we want to take the chance and thank them for their cooperation.
