Ground control point assignment and determination system

摘要

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for ground control point assignment and determination. One of the methods includes receiving information describing a flight plan for the UAV to implement, the flight plan identifying one or more waypoints associated with geographic locations assigned as ground control points. A first waypoint identified in the flight plan is traveled to, and an action to designate a surface at the associated geographic location is designated as a ground control point. Location information associated with the designated surface is stored. The stored location information is provided to an outside system for storage.

主权项

1. A method implemented by an unmanned aerial vehicle (UAV) comprising one or more processors, the method comprising:
receiving information describing a flight plan for implementation, the flight plan specifying geographic locations in a real-world area assigned as ground control points, each geographic location being associated with a waypoint to which the UAV is to navigate and perform an operation to designate a surface of the geographic location as being a ground control point; performing, for a particular waypoint, an operation to designate a surface associated with the particular waypoint as being a ground control point, the operation comprising:
navigating the UAV at a first altitude to the particular waypoint,descending towards the surface, and placing a physical marker carried by the UAV onto the surface thereby creating an identifiable mark on the surface, such that the physical marker is aerially identifiable as a ground control point in one or more images obtained during a subsequent flight plan to perform a job, anddetermining location information of the identifiable mark; andproviding the determined location information to an outside system for storage as being associated with a ground control point.
