摘要 针对叶面积指数(LAI)测量仪存在速度慢、效率低和成本高的问题,结合虚拟植物-虚拟环境与虚拟仪器,以荔枝树为研究对象,进行了LAI测试系统的计算机模型仿真与构建.LAI测试系统一方面通过LabVIEW实现基于VC++和OpenGL的计算机模型仿真程序的调用和调试,另一方面对环境温度、电机温度、滑块位置等参数进行分析、存储和显示,并计算出LAI和输出控制命令,控制电机移动传感器. Leaf Area Index(LAI) is an improtant structural parameter in evaluating physiology and biology of vegetation canopy and ecosystem. It is necessary to have the LAI measured quickly and precisely. However, it is still not realized. A virtual LAI measurement system with computer model simulation is introduced by integrating virtual plant, virtual reality and virtual instruments accordingly. The system compiles Open GL and VC + + with LabVIEW for computer model simulation. Meanwhile it analyzes, saves and displays data, calculates the LAI and outputs the motor control order to realize the sensor movement. The system is satisfied to our project requirement after comparison and calibration.
