| Abstract: | A preprocessing system applied to aerial photograph measurement is designed.The system includes camera data processing and controlling subsystem.The part of camera data processing is to implement data communication with recording system and data transport system on the plane.The data from CCD camera are demanded to combine,compress,store and video encode. Controlling subsystem is to achieve serial port communication with other systems,temperature controlling and voltage conversion.The theory and realization of data communication through PC bus between video encoding chip and single-chip are presented.The system is validated and satisfies the requirement to aerial photograph measurement. |
