Abstract:	林木材積為森林資源調查之重要參數，對於森林資源經營有其重要性。本研究擬利用光達(LIDAR, LIght Detection And Ranging)高密度、高精度測點之特性，以地面光達(terrestrial lidar)掃描立木取得大量三維點位座標，據以重建立木之三維模型，並量測立木之樹高、直徑等重要參數，達到以非破壞性之方法精確估測立木材積，進而推估林分材積之目標。 Stem volume of a forest stand is an important characteristic for forest resource inventory, which is essential for forest resources management. LIDAR (Light Detection and Ranging) is characterized by its capability in collecting data with very high accuracy and high density. This study use terrestrial LIDAR to acquire large amount of 3-D coordinates of points data about trees. The lidar data are used to reconstruct 3-D model of trees, and to derive important parameters of trees such as heights, and diameters at breast height. The main objective is to develop a methodology for estimation of tree volume using nondestructive approach, furthermore, the stand volume can be estimated
