An isolated point “ s statistic excluding method is proposed in this paper to eliminate crassitude error in clouding data , which include plenty of oddity data . the method based on the distance between two neighbour points can eliminate the data beyond normal distribution . a error limitation of angle and chordal highness method is used to filtrate clouding point 針對大量含奇異點的數據點云,本文提出了剔除粗大誤差的孤立點統計排異法,該方法根據對相鄰點距離的統計,剔除在正態分布以外的點;對大量數據的精減,利用角度和弦高的最大允許偏差法進行點云精減。
