| 摘 要： | 在分析保护性耕作地块覆盖秸秆和土壤亮度存在差异的基础上,以MATLAB为工具,采用自动取阈图像分割算法,提取田间实拍图像中的秸秆及土壤信息,统计图像中秸秆覆盖面积,利用秸秆覆盖率算法实现对地表秸秆覆盖率的自动检测。系统经田间模拟试验校正后,田间测试误差可控制在4%以内,平均检测效率可提高约72倍,为开展保护性耕作技术秸秆覆盖研究提供了一种可行有效的方法。

| Abstract: | Based on the brightness differences between residues and soil in conservation tillage,the system in this study case adopted MATLAB to segment the image by automation threshold.Through this,we can Abstract and calculate the information of residue/soil from the original digital images,and in turn measure the residue coverage rate on soil surface.After simulation and parameter-adaptation on field experiments,the system variability was reduced to 4% and the measuring efficiency significantly was improved by a factor of 72.Therefore,the system is regarded as an effective method of investigating residue coverage in conservation tillage. |
