摘要
针对现有作物茎秆直径测量方法测量范围窄、操作复杂、成本高及对作物茎秆生长有一定约束等局限性,采用机器视觉技术研发了作物茎秆直径测量仪。实验结果证明,该仪器具有测量结果准确、操作简单、可对作物茎秆微直径微变化进行无损测量等优点。该仪器的研发为深入研究作物茎秆直径微变化与水分胁迫之间的密切关系奠定了数据基础,对农业节水灌溉技术的发展具有重要意义。
The current method of plant stem diameter measurement have disadvantages of narrow range,complex operation,high price and restricted plant growth,etc.An diameter measurement instrument for plant stem has been developed applying machine vision technology.From the result of test,it can be proved that the instrument has the advantages of high precision,simple operation,high efficiency,and scatheless measurement.Development of the instrument establishes the data foundation for lucubrating the relationship between stem diameter micro-variation with water stress,there is significance for the development of agricultural saving irrigation.
