High-precision reconstruction model of complex blade is of great significance for further researches,as leaf is one of the most important organs of plants.However,it is difficult to reconstruct due to the problems that noises and holes may exist in the real point cloud data.A method based on laser point clouds was proposed,which was composed of de-noise processing of laser point cloud,delaunay triangulation to generate mesh surface,and mending of the holes.Experiments showed that the suggested method was of high speed and precision.
