SkySports: hybrid mocap for golf Open Championship

Updated: Feb 10

Combining volumetric capture and motion capture to analyse the swing of professional golfers, the groundbreaking ‘Sky Scope’ at last year's Open recreated some of the star players using holograph replicas. 

While volumetric capture can capture a certain amount of movement, it won’t capture the speed at which the club is travelling. Target3D formed part of the team working in the Dimension Studios new Polymotion Stage, overseen by MRMC, to create a hybrid solution of the volumetric capture with an optical system, using optical markers to track the swing of the club.

This enabled the animators to receive the golf club data, receive the motion data and apply them together in post-production. The final result is of the holograph golfer performing his swing in 3D. The speed at which the club travelled and the projection are both trackable and analysed.

Projects like this need development to get right so from the very first tests at Studio T3D, weeks and weeks of test followed in the lead up to the install and roll out. First, we mimicked the dome in another location. The volumetric team set up their rig then Target3D set up the motion capture rig, both systems were calibrated before a ‘worlds align’; the volumetric virtual space and the mocap virtual space were mapped together to get the correct X, Y and Y coordinates. This makes it easier for the animators later to line up the data from the optical system with the data from the volumetric capture system.

Target3D’s Petros DeDoncker looks back on the project, “This hybrid solution has been done before but not at the quality level of this. Previously, in the States it’s been accomplished a 2k results, our volumetric capture tests went up to 4k."
