Shanghai Research Institute of Building SciencesQShanghai 200032QChinaQ? Abstract The influence area of coal mining mainly concentrates on farmland and villages.Some villages have dense buildings and poor observation conditionsQso the traditional total-station coordinate method can not be used for oblique survey. Compared with traditional measurement methodsQ?D laser scanning technique has the advantages of high densityQhigh preci? sion and fast acquisition to obtain three-dimensional space coordinates of object surface.Based on the analysis of existing algo? rithmsQa method of building feature line extraction based on the fitting plane of RanSAC algorithm is proposed.RanSAC algo? rithm is used to fit the k-neighborhood point set in planeQand the feature points are judged and extracted according to the ratio of the point set belonging to the best plane model.The study results show that compared with the feature line extraction meth? od based on point cloud curvatureQthe algorithm mentioned above can clearly and completely extract feature lines. Besides re? taining detailed featuresQit is less affected by noise.Compared with the results of total station coordinate methodQit is indicated that the inclination difference is less than 1/10 of the allowable oblique valueQwhich meets the accuracy requirement of oblique survey for the buildings in mining subsidence area.
