Abstract
A return method or device for an unmanned aerial vehicle (UAV), a UAV and a storage medium are provided. The method includes: detecting whether a sensor for obstacle avoidance fails; if the sensor fails, determining a return path of the UAV based on a first return strategy; if the sensor operates normally, determining the return path of the UAV based on a second return strategy; the first return strategy includes controlling the UAV to fly to a return altitude; the second return strategy includes determining the return path of the UAV based on detection data from the sensor. The combination of these two return strategies can achieve a balance between the return efficiency and safety of the UAV.
Claims20
A return method for an unmanned aerial vehicle (UAV), comprising:
- detecting an operating state of a sensor for obstacle avoidance;
- and
- controlling the UAV to execute a first return strategy or a second return strategy based on a detection result of the operating state of the sensor, wherein
- the first return strategy comprises controlling the UAV to fly to a return altitude in response to the sensor's failure to satisfy a preset obstacle detection requirement, and
- the second return strategy comprises determining a return path of the UAV based on detection data from the sensor in response to the sensor being in normal operation.
A return method for a UAV having a vision sensor, comprising:
- detecting an ambient light brightness of a current environment;
- and
- controlling the UAV to perform a first return strategy or a second return strategy based on a detection result of the ambient light brightness, wherein
- the first return strategy comprises controlling the UAV to fly to a return altitude in response to the ambient light brightness being lower than a preset threshold, and
- the second return strategy comprises determining a return path of the UAV based on detection data of the vision sensor in response to the ambient light brightness being higher than the preset threshold.
A UAV, comprising:
- a body;
- a power system in the body to provide power for the UAV;
- and
- a return device in the body, comprising:
- at least one storage medium storing at least one set of instructions for returning, and
- at least one processor in communication with the at least one storage medium, wherein during operation, the at least one processor executes the at least one set of instructions to cause the return device to at least:
- detect an operating state of a sensor for obstacle avoidance,
- control the UAV to execute a first return strategy or a second return strategy based on a detection result of the operating state of the sensor, wherein
- the first return strategy comprises controlling the UAV to fly to a return altitude in response to the sensor's failure to satisfy a preset obstacle detection requirement, and
- the second return strategy comprises determining a return path of the UAV based on detection data from the sensor in response to the sensor being in normal operation.
