MODULE OF DIGITAL TREATMENT OF VIDEO SIGNAL
The module is intended for treatment of video signal in the system of technical
sight and delivery signals of management of proportional to rejection of chosen by
an operator object relatively center of TV of raster. The module is developed on
the base of the digital alarm processor TMS320VC5409.
The module provides:
- input, transformation in a digital kind and treatment of video signal;
- Determination of position of the chosen object of supervision in relation to the
center of raster of centroid and correlation by methods;
- forming of analog tensions of proportional to rejection of watching window
relatively center of raster;
- «capture» and auto accompaniment of the set object by a watching window;
- Involvement in video signal of duty signals «positioning» and «marks of indication»
- forming and delivery of signals of synchronization;
- reception and transmission on the interface of RS 232 housekeeping information,
involvement of her in video signal.
