New Hybrid Algorithms for Estimating Tree Stem Diameters at Breast Height Using a Two Dimensional Terrestrial Laser Scanner

In this paper, a new algorithm to improve the accuracy of estimating diameter at breast height (DBH) for tree trunks in forest areas is proposed.First, the information is collected by a two-dimensional freetress deep twist crochet hair 14 inch terrestrial laser scanner (2DTLS), which emits laser pulses to generate a point cloud.After extraction and
