High-precision synchronous sampling system for tracking and measurement of video

A synchronous sampling system for measuring and controlling data in tracking and measurement of video at real-time is designed. According to the synchronous signal of the measuring and control information, using high-precision timer on information measuring and control card, the accurate adjustment of exposure time is realized through correction of exposure signal of the camera by software with video sampling card. Storage and transfer storage of data without distortion is carried out by high-speed bus, and files are organized by AVI technique, making full use of the image space of measuring video.
