The introduction of Semi Global Matching (SGM) and Structure from Motion (SfM) has created new vistas in the point cloud creation process. These methods are currently integral to the UAS based data processing. Now that point clouds can be created from a laser scanner or from overlapping images, it is necessary to get an understanding on the characteristics of the point clouds created from different capture methods.
Dr. Srini Dharmapuri, MA Engineering Consultant’s Geospatial Director in our Dulles, VA office has developed a two part paper on the evolution of point cloud. Part One of the paper has been published in the current edition of the LiDAR magazine titled “Evolution of Point Cloud” and Part Two will be published in the subsequent edition.
