and encoded values of the zoom and focus (which are measured by
conventional mechanical sensors). The 19 inch rack-mountable unit identifies
the targets in the image, measures their positions to sub-pixel accuracy and
reads their bar codes. Knowing the positions of each target in the studio,
which are stored in non-volatile memory, the position and orientation of the
camera can be computed.
The unit generates an RS422/RS485 serial data stream, which conveys the
position, orientation, zoom, and focus data to the virtual set system.
There is a BNC connection available to monitor the operation of the TSC.
Monitoring of this NTSC signal will be required during calibration.
On initial installation the default control parameters should be loaded into the
free-d™ Processor Unit. This can be achieved by operating the card switches
in the following sequence: Hold RESET (S1), hold STORE (S4), release
RESET, wait until self-tests are complete, release STORE. The default
parameters may then be stored in the unit's non-volatile memory by another
operation of the STORE switch.
