A Deep Learning Time Series Approach for Leaf and Wood Classification from Terrestrial LiDAR Point Clouds

Abstract: The accurate separation between leaf and woody components from terrestrial laser scanning (TLS) data is vital for the estimation of leaf area index (LAI) and wood area index (WAI). Here, we present the application of deep learning time series separation of leaves and wood from TLS point clouds collected from broad-leaved trees. First, we use a multiple radius nearest neighbor approach to obtain a time series of the geometric features. Second, we compare the performance of Fully Convolutional Neural Network (FC… Show more

“…Han and Sanchez-Azofeifa [ 36 ] investigated the leaf and wood terrestrial laser scanning (TLS) time series classification with Fully Convolutional Neural Network (FCN), LSTM-FCN, and Residual Network (ResNet). CNN has been found to be capable of performing time series classification satisfactorily, as its multiple filters can produce multiple discrimination features for classification from the temporal inputs [ 35 ].…”

“…The use of PlanetScope monthly basemap mosaics in the visual spectrum (R, G, and B bands) provided by Planet Labs at 4.77 m resolution could facilitate large-scale applications of imagery. By careful training of RGB imagery as input data, deep learning models have the capability of learning complex patterns and detect forest loss accurately over varied landscapes (Han and Sanchez-Azofeifa, 2022).…”
