We propose a method of improving the reconstruction of edges and corners in surface meshes of sparsely populated point clouds by exploiting the presence of planes in the scene, the calculated geometry of the cameras and the images themselves. By robustly identifying co-planar points in the point cloud, isolating suitable plane-pairs for intersection, identifying the regions-of-interest along the lines of intersection and then creating points along these line segments, new points are added to the point cloud. The success of this approach is shown by using a robust Image-Consistent Triangulation method to mesh the point clouds before and after augmentation.
