遥感摄影在对地观测中的应用日益增多,为了能使更多的人较直观地认识遥感摄影系统,研究开发遥感摄影模拟系统对于在实验室模拟真实遥感摄影系统有重要意义.该模拟装置用普通可见光线阵 CCD 相‘机推帚采集图像,且图像数据无线传输.在电路设计中遵从系统模块化设计思想,提出了以 TI 公司的DSP(TMS320VC5402)和 A7121无线收发模组为核心器件的发射系统和接收系统的设计方案,通过 USB 芯片PDIUSBD12实现了采集电路与计算机的通信.给出了相应的硬件设计和软件流程图,调试结果表明该系统可以满足对图像进行实时采集并显示的要求. In order to enable more people to understand the remote sensing photography system more intuitively, the research and development of the remote sensing photography simulation system is of great significance to simulate the real remote sensing photography system in the laboratory.This simulation device uses General visible light array CCD phase ’machine broom to collect images, and image data wireless transmission.In the circuit design to comply with the system modular design ideas, put forward to TI’s DSP (TMS320VC5402) and A7121 wireless transceiver module as the core device The transmitting system and the receiving system are designed, and the communication between the collecting circuit and the computer is realized through the USB chip PDIUSBD12.The corresponding hardware design and software flow chart are given, and the debugging results show that the system can meet the requirement of real-time image acquisition and display .
