ABSTRACT
I will present a study on the use of triangulation based laser camera systems (LCS) for rockmass characterization. The LCS produces a point cloud which as an unstructured collection of points (voxels) in 3D space. This study looks at the use of 3D image processing techniques to visually enhance features of interest with respect to geological structures. We have studied three different scenes each of which has different geological characteristics. We take a 2.5D triangulated mesh of the point cloud and process it using the following techniques: automatic labeling of each triangular element based on how geologists measure planar orientation, compute the curvature of the mesh for each point, and an alternate planar orientation method which is based solely on the normals of each triangle. We present the results of each of the processing techniques, what features are enhanced through a visual image |
