Abstract Controlling by rock mass structure，the stability of rock mass in meizoseismal areas is particularly prominent. In this paper，the dangerous rock mass along the Ludian National Highway in Yunnan was taken as a typical example. A method to visually identify structural planes and quickly extract characteristic information by using point cloud directly was proposed. Firstly，based on the point cloud，the random Hough algorithm and the Fuzzy C-means algorithm were used for clustering analysis. Then the Fast-Marching algorithm was applied to reconstruct the dominant structural planes in three dimensions，to realize the characteristic information extraction of geometric information and spatial distribution state of structural planes. Meanwhile，based on the extracted characteristic information of structural planes，combined with HSV technology，the in-situ dangerous rock mass was identified and counted. The Monte Carlo simulation was also used to compute the in-situ rock volume distribution. Finally，the kinematic analysis of the dangerous rock area was carried out to judge the instability failure mode of the dangerous rock mass. The research results have a certain reference value for the investigation and evaluation of road dangerous rock mass in meizoseismal areas and the energy level design of protective structures.
