Abstract
A method of building a two-dimensional (2D) elevation map includes receiving sensor data regarding a 2D coordinate in a 2D coordinate system, computing a surface height for the 2D coordinate based on the sensor data, assigning a confidence indicator to the computed surface height based on the sensor data, and storing the computed surface height and the assigned confidence indicator for the 2D coordinate in a database, thereby building the 2D elevation map. The sensor data is acquired by one or more sensors of an aerial vehicle;
Claims20
A method of building a two-dimensional (2D) elevation map, comprising:
- 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;
- computing, based on the sensor data, a surface height for the 2D coordinate;
- assigning, based on the sensor data, a confidence indicator to the computed surface height;
- and
- storing the computed surface height and the assigned confidence indicator for the 2D coordinate in a database, thereby building the 2D elevation map.
A system for building a two-dimensional (2D) elevation map, comprising:
- at least one memory;
- and
- at least one processor connected with the at least one memory and configured to perform:
- 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;
- computing, based on the sensor data, a surface height for the 2D coordinate;
- assigning, based on the sensor data, a confidence indicator to the computed surface height;
- and
- storing the computed surface height and the assigned confidence indicator for the 2D coordinate in a database, thereby building the 2D elevation map.
