WIPO Patent Application WO/2018/086141
Kind Code:
A1
Abstract:
Systems and methods for building a two-dimensional (2D) elevation map are provided. A method of building a two-dimensional (2D) elevation map comprises: receiving sensor data regarding a 2D coordinate in a 2D coordinate system, wherein the sensor data is acquired by one or more sensors of an aerial vehicle (1310); computing, based on the sensor data, a surface height for the 2D coordinate (1320); assigning, based on the sensor data, a confidence indicator to the computed surface height (1330); and storing the computed surface height and the assigned confidence indicator for the 2D coordinate in a database (1340), thereby building the 2D elevation map.
