Specifications

The hardware set-up of VioTrack F is very easy. Basically only the sensor camera and the lens are connected to the Tracking PC. The Tracking PC uses a dedicated Linux operating system, especially designed for the real-time needs of our image processing software. The final UDP camera tracking data are sent to the Graphics Engine through a regular network.

There are two versions of VioTrack F available:

F1     For cameras with a very limited moving range we designed VioTrack F 1, where the coded floor is limited to a size of 2x2 meters. E.g. you can use this version as a replacement of a sensorized pan-tilt with height sensor. But as a retrofit kit, VioTrack F1 works without any dedicated hardware, just with any device.

F2     For an unlimited tracking range and any studio size VioTrack F2 provides unlimited camera movements. E.g. you can use this version for any pedestal, dolly, jib, crane or steadicam: it works for any support system, any camera, any studio, any environment.

The design, size, color and shape of your coded floor will be individually designed for your environment and needs. Therefore we can prepare a solution for any demand.

working principle

Video based. A unique code printed on the floor is detected and analyzed by a dedicated sensor attached to the broadcast camera.
 

degrees of freedom

Free movement of all camera axes (6
 

limitations

Sensor camera must be able to recognize the markers. Thus, movement is limited to the area covered by the coded floor and a limited space in its proximity.

Extensive roll and tilt angles may lead to a loss of visibility of the coded floor
 

Overall Delay

3 frames
 

Sensor Camera

size:  50 x 50 x 90 mm
weight: 500 g
power: 12V, 1 A

output: Video Signal or Ethernet Network

 

Tracking PC

Engine with TrackMen Linux distribution and video input card; different models like Workstation, Small Form Factor (SFF) or 19” rack mount available

 

 

Video Input

video card supports 8/10-bit uncompressed SD/HD video streams according to SMPTE-259/292/296
 

Reference Signal

Not needed – system synchronizes on video input signal
 

Lens Data

Receives serial data from TV lens: Canon (RS 485) or Fujinon (RS 232) Virtual protocol types are supported.

If serial lens data interface is not available, external encoders can be mounted to the lens
 

Data Output

Network connection:
10/100/1000 Mbit Ethernet (IEEE 802.3)
UDP/IP-protocol (RFCs 793, 791 und 768)

The Xync camera tracking interface is employed as the interface protocol.
