Abstract
Systems, methods, devices, and non-transitory media of the various embodiments enable for updating a point cloud, such as a two-and-a-half-dimensional (2.5D) point cloud. Various embodiments include receiving two point clouds, such as a base point cloud of a terrain area and a new point cloud of the terrain area, and fusing the received two point clouds to generate an up-to-date point cloud, such as an up-to-date point cloud model of the terrain. Various embodiments may be especially useful in generating models of terrain areas, such as construction sites, earthwork projects, shorelines, etc., surveyed by surveying technologies, such as drone-based aerial photogrammetry systems, Light Detection and Ranging (LiDAR) systems, etc.
