摘要
为了快速、准确地测量植物叶面积,本文提出了一种基于可编程片上系统技术和图像处理技术的便携式叶面积测量方法。该系统通过摄像头采集叶面积数据,利用FPGA特有的并行工作方式对原始数据进行图像处理,提高叶面积测量精度和速度,采用具有Nios II嵌入式软核处理器的现场可编程门阵列控制系统,提高整个系统的管理效率。田间实地测量表明该系统能够有效地采集叶面积数据,并具有测量速度快、可扩展性强和携带方便等优点。
In order to measure plant leaf area quickly and accurately, a portable leaf area measurement method based on programmable system- on-chip and image processing technology is proposed in this paper.The system collected the leaf area datas through the camera,utilized the unique parallel working mode of FPGA to process the raw data, and improved the accuracy and speed of the leaf area measurement.The field programmable gate array control system with Nios II embedded soft-core processor was adopted,improved the overall system management efficiency. Field measurements showed that the system could effectively collect leaf area data, and had the advantages of fast measurement speed, scalability and easy to carry.
