Paper presented at the 43rd U.S. Rock Mechanics Symposium & 4th U.S. - Canada Rock Mechanics Symposium, June 28–July 1, 2009
Paper Number: ARMA-09-123
... Abstract This paper presents a new method for analyzing point cloud data of rock surfaces obtained using a ground based LiDaR system. The method allows the user to specify a reference plane and a grid of cylinders used to sample the point cloud. Output from the program includes orientation and...

... combination with PM. For example Z/I ImageStation can help develop complex surface models with automated point cloud generation. PM alone does not have the capability to automatically generate the point cloud data. However, to do this, the site must also be shot in stereo and the camera positions and...
