基于FPGA图像处理的天空云量采集显示系统

摘要

云量对气候研究具有十分重要的意义,常规的观测主要以目测来实现,而复杂高精测量则通过精密的全天空成像仪实现.为了实现方便快捷的云量测量的目的,我们提出设计实现一个基于FPGA图像处理的天空云量采集显示系统.系统通过结合对CMOS面阵传感器的数据进行FPGA片内设计和NiosⅡ软核设计进行实验,得出可以实现天空云量图像的显示和测量功能的结果.经实验测量表明,该系统操作简单,运行稳定,达到设计要求.%Cloud amount is significant to climate researches. Normal observation is mainly achieved by visual inspection while complex and high-precision measurement can only be realized by all-sky camera. In order to make cloud amount observation convenient and efficient , we design and implement an acquisition and display system of cloud amount based on FPGA image processing. The system , through the data of CMOS array image sensor, conducts FPGA chip-on design and Nios Ⅱsoft core design so as to realize the display and measurement of cloud amount image.As is shown by experimental measurement, the system, with high running stability, is easy to operate and meets design requirements.
