Embodiment Construction

[0066] The present disclosure provides systems and methods for controlling movable objects such as unmanned aerial vehicles (UAVs). In some embodiments, the UAV may be adapted to carry a plurality of sensors configured to collect environmental data. Some of these sensors may be of different types (eg vision sensors used in combination with distance sensors). Data acquired by the plurality of sensors may be combined to generate an environmental map representing the surrounding environment. In some implementations, an environment map may include information about the location of objects in the environment, such as objects or obstacles. UAVs can use the generated maps to perform various operations, some of which can be semi- or fully automated. For example, in some implementations, a map of the environment may be used to automatically determine a flight path for the UAV to navigate from its current location to a target location. As another example, a map of the environment may...

Abstract

The invention provdes a system and a method used for controlling a movable object in an environment.The method comprises following steps: utilizijng at least one sensor of multiple sensors carried by the movable object to determine the initial position of the movable object; generating a first signal in order to navigate the movable object in the environment; utilizing at least one sensor of the multiple sensors to receive sensing A data of the environment; generating an environment map of at least one part of the environment based on sensing data; receving an instruction for nagtaivation to the initial position; and generating a second signal in order to negative the movable object to the initial poisution based on the environment map.

Description

Background technique [0001] Unmanned vehicles, such as unmanned aerial vehicles (UAVs), can be used to perform surveillance, reconnaissance, and exploration missions in a variety of environments for military and civilian applications. UAVs may be manually controlled by a remote user, or may operate in a semi-autonomous or fully autonomous manner. Such UAVs may include sensors configured to collect data from the surrounding environment. [0002] In some cases, existing methods for obtaining environmental data may not be optimal. For example, the accuracy of environmental data may be limited based on the capabilities of the particular sensor type used to collect the data. Inaccurate environmental data may adversely affect UAV functionality. Contents of the invention [0003] Embodiments disclosed herein provide improved methods for controlling movable objects, such as UAVs, within an environment. In many implementations, UAVs incorporate a variety of different sensor types...
