番茄群体冠层形态结构三维模拟——基于实测数据

3-Dimentional Morphology Simulation of Tomato Canopy——Based on Measured Data

为了提供较精确的作物冠层几何模型进行作物冠层光分布计算研究,首先实际测量番茄器官、个体及群体的形态特征参数,进而基于实测数据对番茄器官、个体及群体进行三维重建,使用C++语言和OpenGL函数库,开发了番茄群体可视化软件,可实现番茄群体三维模型的快速生成。基于精确器官模型和实测数据建立的番茄群体三维模型,较好地反映了群体冠层结构的基本特征,为作物冠层生产力计算和评价建立了几何模型基础。

In order to provide a precise crop canopy geometric model for the study of crop canopy light distribution calculation,we firstly extract characteristics parameters from tomato organs,individual and population,and carry on the actual measurement,and then based on the measured data of tomato organs,we reconstruct the individual and population of tomato,and develop the tomato group visualization software,which can generation tomato group 3D model fast,by using C++ language and OpenGL function library.The 3D model of tomato groups which is based on the measured data model and precise organs better reflects the group canopy structure characteristics,and has higher precision for crops.The canopy model also provides a good basis of geometric model for productivity calculation and evaluation.
