Camera tracking systems determine the pose of the employed camera and support system in order to render the virtual image from the same perspective as the real camera. Traditional tracking systems require new equipment with external sensors at each axis of the individual support system and precise calibrations.
In opposite to this, VioTrack uses image feature points within the video picture of the camera to place the virtual graphics exactly at their desired position within the set. VioTrack’s unique markers are placed everywhere the action is needed, identified by image processing and located in 3D. As the stunning result, Virtual graphics are precisely sticking to the set.
VioTrack is designed in three different versions to fit your desired degree of camera freedom and budget best. Choose the most cost effective VioTrack S1 for basic camera movements, the VioTrack S2 which enables a free moving camera or the VioTrack S3 version for free camera movements for all axis.
video based camera tracker works independent of the camera support system
VioTrack does not rely on sensor data from any other devices or support systems, like encoded pan-tilt heads, inertial sensors etc. Therefore the tracked camera can be used for various support systems. Just lift your broadcast camera and mount it to the next support system and it is immediately ready to use.
works with every camera, lens and support system, just retrofit
Viotrack works with every type of camera, any type of lens and any support system. Even better, you can keep your existing equipment and just retrofit with Viotrack. This is the most affordable solution to step into Virtual applications.
get rid of standard 2D video walls or projection systems and use a 3D Virtual Depth Screen
All video walls, screens or projections are just showing a flat 2D image. But with VioTrack a Virtual Depth Screen creates stunning 3D depth effects where 3D sceneries can be seen from different camera angles and the content leaves the picture frame. Even if your backplane is just flat, the Virtual Graphics blasts your standard screen plane and will occur behind and in front the standard screen, inside or even outside this frame.
any size and shape, even large backplanes or Virtual Studios with no extra costs
For VioTrack it does not matter if you are using a small screen or the whole studio walls. The same systems tracks any sized green or blue screen.
Independet of the size of your screen you always achieve an optimum picture quality with a higher contrast than with a projection, a higher resolution than a video wall and you just need one renderer, you can even zoom in, no borders between monitors, no reflections
open real-time data transfer interface to any Virtual Graphics system
Works with every Virtual Graphics software thanks to the open interface. The complete camera tracking data are sent to the network to an unlimited number of graphics machines.
Designed for basic camera moves, based on pure image processing
While the camera can change the pan, tilt, zoom and focus, the fixed camera position allows you to reliably work with 3D graphics.
Here just the TV camera video picture is processed by the unique real-time image processing algorithms. Therefore no additional sensors are required, no special hardware is dedicated to this setup.
Designed for free moving cameras
In addition to VioTrack S 1, Viotrack S2 employes the zoom and focus data of the applied TV lens. Therefore VioTrack S2 is able to determine the 3D position and orientation of the camera precisely. Now the camera can be moved with the help of a pedestal, a crane or even just your shoulder!
Designed for free camera movements for all axis
In addition to VioTrack S2, Viotrack S3 employes a dedicated sensor camera which is rigidly attached to the TV camera and observes the scene. Therefore it is not longer necessary that the TV camera sees the video features, the sensor camera always has the features in view!
This enables the TV camera to even fully zoom in while moving in 3D space.
The individual feature markers can be set anywhere in the studio, the back wall, the studio ceiling or the floor. The individual calibration of the single markers position establishes a reliable set-up for the camera tracking.
