摘要： In a point cloud reduction method, a point cloud model and a predetermined reduction ratio are received, and a boundary box of the point cloud model is computed and divided into a plurality of grids according to the predetermined reduction ratio. A point set which includes points in the one or more adjacent grids is obtained and a plane which intersects with a center point of the point set and takes a feature vector of the point set as a normal vector is constructed. A curvature of each point in the point set to the constructed plane is computed, and then an average curvature is computed according to the curvature of each point. Points can be deleted from the point set according to differences between the curvatures of the points in the point cloud model with the average curvature, to generate a reduced point cloud model.
