摘要
为满足CCD成像电路集成化、小型化的发展需求,设计了一种高性能的新型成像电路系统,采用FPGA作为成像系统的控制核心,产生A/D转换器的配置驱动信号实现模数转换,对图像数据进行编码合成转换成数传格式输出成像,通过遥测遥控三线接口实现成像系统与外部的通讯,用以接收星上辅助数据及成像参数调整指令等。实验结果表明,设计的成像电路软件能够满足卫星相机视频处理功能的测试需求,成像效果清晰,简化了硬件电路的同时提高了软件集成度,具有很高的工程应用价值。
In order to meet the needs for the integration and miniaturization of CCD imaging circuit,a new high performance imaging circuit system is designed in this paper.Using FPGA as the core of the imaging circuit,configuring the A/D converter to realize analog to digital conversion,coding and synthesizing the converted image data and arranging the data transmission format,realizing the communication between the imaging circuit and the outside by the telemetry and telecontrol three wire interface,so as to receive the auxiliary data on the satellite and the adjustment instructions of the imaging parameters.The experimental results show that the imaging circuit software designed in this paper can meet the test requirements of video processing function of satellite camera.The imaging effect is clear,the hardware circuit is simplified and the software integration is improved.It has high engineering application value.
