摘要: 本文在道格拉斯-普克法的基础上提出利用逐点前进法对点云数据进行精简,以兔子的模型为对象进行试验研究。结果表明,逐点前进法对点云数据精简在速度和精简率上与道格拉斯-普克法相比有明显提高。

关键词: 地面激光扫描, 点云数据, 道格拉斯-普克法, 逐点前进法

Abstract: The paper proposes a point-by-point forward method to streamline point cloud data. The experimental research is carried out by the rabbit model, and the results show that the point-by-point forward method is significantly higher in speed and reduction rate than the Douglas-Peucker method in streamlining point cloud data.

Key words: terrestrial laser scanning, point cloud data, Douglas-Peucker, point-by-point forward approach
