Abstract


Shipboard photoelectric platform stabilization and tracking technology has become more and more mature , stable the shipborne TV equipment tracking continuously improve performance . Photoelectric platform framework in the trace of the movement , so that a stable image is superimposed on the rotation of the additional inconvenience to the viewer , the image rotation compensation technique called image (in this racemic technology) to become a necessary research . Developed an ultra-large-scale FPGA and floating - point digital signal processor for real-time image of the core of the racemic system , given the specific hardware and software design , and focus on how to use FPGA to achieve real-time image of the racemic interpolation and fill algorithm , the image angle of the the DSP receiving computer serial port to send information , and participate in the auxiliary calculation , real-time display on a TV through the the DA chip output PAL-D standard TV signal . The system not only can realize the real-time image racemization, can also be used to validate the various real-time image processing algorithms . The article also discussed the ideas and methods of the the pure electronic racemic system design . The experimental results show that the image racemic processing algorithms implemented on FPGA , to good effect , and to meet the system requirements of real-time , and the system has reached the desired objectives . Finally , the summary of the system design and commissioning experience , some of the problems encountered in debugging .
