VioTrack S can be used with several different patterns, their design and size are calculated individually, according to your environment. Infrared retro-reflecting markers work exceptionally well in critical lighting conditions, colored markers for green/blue boxes to be removed by a chroma keyer.
Unique Infrared retroreflecting markers to work in critical lighting conditions
The visual information of the sensor camera is required to determine the camera tracking data. Like the human eye, the sensor camera might be blind when using low-light conditions or blinded when using changing show-lights.
To overcome these limitations, the VioTrack S sensor camera can be equipped with an additional infrared LED ring - light. It illuminates the retroreflective markers which reflect the light perfectly to the sensor camera. Now the sensor camera works regardless of the environmental light, without jerkiness or failures.
Automated self-calibration of markers
All you must do, is install all the markers in an arbitrary pattern and position within your environment. With the help of your sensor camera, a fast and easy to use self-calibration process begins to calculate the exact position of all markers in 3D space automatically.
This information is now used by VioTrack S to measure the absolute camera pose in real-time. The mounting position of the sensor camera is calculated just based on image processing; no manual measurements are needed.
