Through comparing research of the statistical results in photogrammetry data of stumpage and measured data of total station,the result indicates that people may gain more reliable data by multi-baseline digital close-range photogrammetry system,accurately monitor forest and meet the need of forest measurement by this system. At the same time,by establishing three-dimension point cloud model based on 3-D model of tree,people may expediently gain forest measurement factors which shall be harder by traditional methods.展开更多
