Study Of Multi-camera Synchronization Test Technology Based On Field Testing

Time unified system is a large scientific research and an important part of test, it provides a standard for testing all the time and frequency signal, which is in order to achieve unity of the time and frequency in Experimental system as a whole test common purpose of the experiment is completed relying on time unified system information to make different test equipment synchronized.This is in-depth study of the B time code integration testing in a multi-camera synchronization of Applied Technology, and the application of GPS technology. Integration module design takes use of AVR microcontroller, FPGA, and GPS module. System flexibility provides two kinds of synchronization mode:GPS time synchronization and B code time synchronization.We can improve the accuracy of the entire system,taking use of GPS module timing precision. B code synchronization is fit for time synchronization between the closer distance various subsystems.
