FLIGHT CONTROL METHOD, APPARATUS AND DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/195875
Kind Code:
A1
Abstract:
Provided are a flight control method, apparatus and device, and a storage medium. The method comprises: determining a sampling region by means of location information of key waypoints in a flight task, and collecting one or more first sampling points in the sampling region (S201); furthermore, according to obstacle information in the sampling region, using a first sampling point that meets a first preset condition in the one or more first sampling points as a target sampling point (S202); and determining, according to the target sampling point, an intermediate waypoint of a flight path that can be connected to the key waypoints (S203). Compared with a method for randomly collecting a sampling point in a space in the prior art, computing resources can be saved on by means of determining a sampling region and collecting a sampling point in the sampling region. In addition, when there is an obstacle surrounding a key waypoint, a sampling region is determined according to location information of the key waypoint, such that the interference of the obstacle surrounding the key waypoint for the sampling region can be reduced, the interference of the obstacle surrounding the key waypoint for path planning is thus reduced, and the success rate of path planning can thus be improved.
