摘要: 以15塊樣方調(diào)查數(shù)據(jù)驗證背包激光雷達數(shù)據(jù)提取單木參數(shù)的精度,依據(jù)270塊背包激光雷達數(shù)據(jù)單木分割后計算得到的林分結(jié)構(gòu)參數(shù)與無人機機載激光雷達數(shù)據(jù)特征參數(shù)相結(jié)合,通過最優(yōu)估測模型對研究區(qū)的林分結(jié)構(gòu)參數(shù)進行反演與預(yù)測。結(jié)果表明:(1)背包激光雷達數(shù)據(jù)提取單木參數(shù)時,單木分割F-score(F)得分的范圍在95%~100%,胸徑的均方根誤差(E_(RMS))在0.08~1.68 cm...
