基于点云法矢变化的点云简化方法研究
Data Point Reduction Research Based on Normal Vector Change
摘要
Abstract
To improve the efficiency of entity reverse building, this paper proposed a method to reduce cloud data quickly. This method subdivided point cloud into many cubic grids, searched the nearest neighbors of a measured point based on topologized structure of cubic grids, and adopted a self-adjustable algorithm based on triangle surface to compute the normal vectors of every metrical point Then the distance between the metrical point and local plane was computed, and the data point was reduced according to the set bonnet value of normal angle and distance. The result shows that this method can obviously impove the efficiency of data cloud reducing.关键词
