| In the course of the theodolite tracking the target,the real-time memory system of ananlogue video image is applied to fulfill real-time capturing and storing task of video image from CCD and afterwards realize functions as follows:image estimating and target trajectory calculating . This paper's main research content is real-time capturing and storing and playback afterwards based on analogue video.Video image data store in the Ultra160 SCSI hardware with the high data transmission rate.Diffrence from the past is the playback afterwards adopted DirectDraw technology. The application program is developed on Windows 2000 operation flatform using Visual C++6.0 program circumstance. In the developing course, I use fully its strong thread manage capability and rich news manage function,as well as friendly interface resource. The developed program in the paper fulfilled real-time capturing and storing of video image and playback afterward without twinkling continuously as well as communication. Memory system of the analogue video image realized real-time capturing and storing of video image from theodolite. |
