Abstract:

The flight scene simulation test is an important part of the characteristic target capture system. To meet the requirements of the flight scene simulation on the real-time performance of image displaying and the high transmission rate of data in the characteristic target capture system, a design of the high-speed image injection module which is applied in flight scene simulation is provided. The FPGA is adopted to make control unit, which controls USB 3.0 and LVDS bus to transmit image. Furthermore, the real-time performance has been improved by image converting based on FPGA, and the continuity of image data transmission has been ensured by the use of double buffer ping-pong mode. The experimental results show the module achieves more than 800Mbps image transmission rate, and guarantees the real time of image displays and the accuracy of image transmission in the meantime.
