High Speed Data Acquisition Of Tracked Targets From Film And Tv Video Sources Using The Semi-Automatic Video Recording System (SAVRS)

The DBA's SAVRS System provides a complete stand-alone measurement system for measuring, processing, and recording video data from 35 mm film and video cassettes. The system will automatically, encode and process frame border data such as, azimuth, elevation, and time, in addition to, automatically tracking high-contrast video targets. On lower-contrast targets or targets requiring redefined measurements, the operator can manually measure, via a trackball and cursor, and record the measurements through a footswitch entry. The SAVRS System operates in one of three distinct modes: 1) manual, 2) semi-automatic, and 3) automatic. The mode is determined by the type data to be processed and the quality of the video input to the system. In addition to the main console in the SAVRS System, an optional previewing station is available for determining which sections of the input media contain valid target information for measuring. During the recording process, while azimuth, elevation, and time data are being captured, a computer-generated target may be superimposed on the actual target. By using the optional attitude control system, the roll, pitch, and yaw of the moving target can be determined at any given time.
