摘要
Abstract
By using the 3D laser scanner to get point cloud data as data sources,and through the classification of cutting to get point cloud data of different natural features. K-neighborhood tree method is used for irregular natural features of point cloud data to neighborhood search,which by set-ting the value of the scale parameter k to the height or low of different on the extraction of feature points,and then compared the result of the feature points. The result show that scale parameter set-tings have significant impact on the larger density of low vegetation point cloud,but have week obvi-ous effect on the low density of high vegetation. Setting the scale parameter between 3 to 5,the exper-imental effect is remarkable.关键词
