| 摘 要： | 用机载激光测高仪对单木树冠进行自动提取和轮廓描绘,是获取森林信息的一种快速有效的方法.机载激光测高仪可通过记录回波波形来描绘单树植被冠盖等细节信息,但由于激光足印较小,很难给出树木种群的细节尺度参数,如树的冠盖大小、树径等.提出把若干小激光足印复合成大激光足印的方法,并通过高斯分解算法导出植被冠层高度、植被冠层反射率和...

| Abstract: | Automatic extraction and delineation of individual tree crown using airborne laser altimeter is an effective method to obtain forest information.The airborne laser altimeter can describe characterization of vegetation canopy structure by recording the time history of the return waveform within a small footprint for each laser pulse,but difficult to give out the large canopy metrics,like the canopy size and stem diameter.A collection of individual waveforms combined within a synthesized large footprint was u... |
