摘　　要：针对叶面积测量方法大多依赖计算机做图像处理,研制了一种嵌入式植物叶面积测量装置,以CycloneⅡ系列EP2C70F896C6为核心器件,用硬件描述语言Verilog设计叶片图像采集单元、图像存储单元、图像处理单元,内嵌NiosⅡ软核处理器完成叶面积计算。设计的关键在于解决了叶片图像实时高速采集问题,并且实现脱机运行。实验结果表明:测量装置能够测量离体叶片叶面积,适当改进,可以应用于测量叶片其他参数。Method for measuring leaf area mostly relied on computers to do image processing.An embedded measurement equipment for plant leaf area is researched and fabricated.EP2C70F896C6 of CycloneⅡ is used as the core device.Leaves image acquisition unit,image storage units,image processing unit are designed using hardware description languages Verilog.The embedded NiosⅡ soft-core processor completes the calculation of leaf area.The problem of real-time high-speed acquisition of the leaf image is solved,and it can operate offline.The experimental results show that the measurement equipment can measure leaf area of detached leaves.It can measure other leaf parameters after some improvements.
