optical camera tracking systems

free camera movement, even for hand-held shots

All our optical camera tracking systems accurately calculate the 3D position and orientation of the camera body itself. This enables any kind of camera movement within the tracking area, also suitable for hand-held cameras. The additional integration of pre-calibrated zoom lens data allows random zoom and focus settings regardless of the camera movements.

works on any support system, just retrofit optical sensor hardware

Optical camera tracking systems measure the position and orientation of the camera body itself and work independently of the camera support system which is currently being applied. Now, you can simply choose between using a tripod, pedestal, dolly, jib arm, crane, Steadicam or even a hand-held camera. Should you choose to switch to a new or rented support system to suit your clients’ needs. There is no need to purchase an additional specialized support system, simply upgrade your existing one.

Due to our system’s versatility, you can reduce costs greatly and be well equipped for all your future production requirements.

mechanical camera tracking systems

rock-solid tracking data for any environment

Mechanical camera tracking systems use a built-in sensor (encoder) for every movement axis of the camera rig and lens. The TorqTrack software gathers all this information to determine the location of the camera support system and camera.

This results in dependable data for any environment, regardless of lighting and weather conditions.

what all TrackMen camera tracking systems have in common

complete camera tracking data - including optical properties of the lens

Besides the position and orientation of the camera, the entire product line of TrackMen's camera tracking systems provides all optical lens parameters, including a field of view angle, distortion, and depth of field data. Due to our unique zoom lens calibration software, all our systems achieve the highest matching quality for any zoom lens.

In general, our systems can use the built-in serial interface of digital broadcast lenses or external sensors for the zoom and focus ring of any lens, including prime or affordable SLR lenses.

open real-time interface to any Virtual Set graphics system

All TrackMen products are compatible with any Virtual Set graphics software due to the open tracking data protocol. The complete tracking data of the broadcast camera is transmitted via network to an unlimited number of graphics rendering workstations. Your tracking system will immediately connect to the leading professional real-time graphics packages as well as to open-source game engines like Unreal, Unity or post-production tools.
