摘要
传统方法未对生成的测绘最优函数进行等效处理导致测绘精度不高,为此,此次开展区域植被生态环境遥感定量测绘方法研究。先通过在测绘区域设置测绘点,采集当前区域的相关数据,对采集的数据进行预处理和补偿计算。然后利用构建线性耦合模型,构建植被生态环境三维模型。最后对生成的测绘最优函数进行等效处理,完成对区域植被生态环境遥感定量测绘方法的设计。实验测试中,和以往的区域植被生态环境遥感定量测绘方法相比,设计的区域植被生态环境遥感定量测绘方法测绘精度平均值为92.1%,测绘精度较高。
The traditional method did not perform equivalent processing on the generated optimal mapping function,resulting in low mapping accuracy.This study conducted a quantitative remote sensing mapping method for regional vegetation and ecological environment.Firstly,relevant data of the current area is collected by setting surveying points in the surveying area,and the collected data is preprocessed and compensated.Then,a linear coupling model is constructed to construct a three-dimensional model of vegetation ecological environment.Finally,the generated optimal mapping function is equivalently processed to complete the design of a quantitative remote sensing mapping method for regional vegetation ecological environment.The designed method is compared with previous quantitative remote sensing surveying methods for regional vegetation ecological environment,indicating a higher average surveying accuracy of 92.1%.
