Development of Crop Growth Spatial Analysis System

摘要:

为了满足作物长势动态测量的要求，设计了作物长势信息空间分析系统，针对作物冠层信息获取手段及其数据特点设计相应的功能模块。系统主要由光谱文件管理、定点作物光谱分析、动态采集监测、空间数据分析等功能模块组成。系统能够兼容多种光谱文件格式，具有两种空间数据分析方法，配有专家数据库接口，具有较强的二次开发潜力。该系统配合车载作物长势检测平台，对玉米的长势空间分析进行了应用效果验证，结果证明：该系统能够实时读取和分析车载式作物长势检测平台的动态数据，通过不同的空间插值方法能够掌握冠层生物信息空间分布状况。该系统为车载动态测量提供了良好的技术支持，可为制定相应的精准管理决策提供理论依据。

Abstract:

In order to meet needs of information acquisition and processing of the vehicle-borne system, a crop growth spatial analysis software for vehicle-borne system was developed. The software system was composed of four functional modules: spectrum file management, canopy spectrum analysis, dynamic monitoring and spatial data analysis. It could read a variety of file types. It also could apply two kinds of spatial information analysis methods and had an interface for expert database. The proposed system was set on crop growth spatial platform to verify the effect of growth spatial analysis system for corn. Field test results showed that the system could generate crop and wheat growth distribution map and interpreted working prescription map correctly. It indicated that the system provided good technical support for the precision management of field crops.
