Innovative Thinking: Evolution of the Point Cloud – Part One

Dr. Srini DharmapuriDr. Srini Dharmapuri, Geospatial Director in MA Engineering Consultants’ Dulles, VA office, has developed a two part paper titled “Evolution of Point Cloud”. This edition of Innovative Thinking focuses on part one of the paper that was published in LiDAR magazine. Part two will be published in the subsequent edition.

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.
