Abstract:

This paper tries to apply Cyclone and Geomagic Studio software for point cloud data processing and 3D reconstruction to study the model error of the four parameters of bamboo crown,breast diameter,height,branch height and the visual effect of indoor and outdoor point cloud data modeling.The results show that:1) the average absolute error of the four parameters of the bamboo model is 38,0.5,189,6(unit:mm) and the average relative error is 1.450%,0.550%,1.775% and 0.350% respectively,which are of high accuracy;2) In the wild,the leaves of the more dense bamboo crown models are triangular,continuous and there are layering phenomena,while when the bamboo leaves are sparse,there are no stratification phenomenon and the overall visual effect is good;3)When the indoor static bamboo crown and stalk is modeled,the crown shape can be shown visually,in which the model effect of sparse crown is better than that of the dense crown,and the surface of the bamboo stem model is smoother without holes.It also can be found that the difference of modeling effect among bamboo stem of various thicknesses is not significant.
