US 2019/0193852 A1 · WATER SURFACE DETECTION METHOD AND APPARATUS, UNMANNED AERIAL VEHICLE LANDING METHOD AND APPARATUS AND UNMANNED AERIAL VEHICLE

Abstract

Embodiments of the present disclosure disclose a water surface detection method, an unmanned aerial vehicle landing method and an unmanned aerial vehicle. The detection method includes: controlling the unmanned aerial vehicle to generate an airflow, where the airflow is used to generate a water surface ripple; obtaining an image of a landing area of the unmanned aerial vehicle and a flight parameter of the unmanned aerial vehicle; and processing the image, and determining, with reference to the flight parameter, whether the landing area has the water surface ripple. Damage caused by erroneous landing of the unmanned aerial vehicle on a water surface can be alleviated by determining whether the landing area has the water surface.

A landing method, applied to an unmanned aerial vehicle, wherein the landing method comprises:

detecting whether a landing area of the unmanned aerial vehicle has a water surface;
and
if there is a water surface, controlling the unmanned aerial vehicle to suspend landing and/or controlling the unmanned aerial vehicle to fly away from the landing area.

An unmanned aerial vehicle, comprising a body and an image collection apparatus connected to the body, wherein the unmanned aerial vehicle further comprises:

an airflow generating apparatus, configured to generate an airflow, wherein the airflow is used to generate a water surface ripple;
a flight control chip, wherein the flight control chip is configured to obtain an image that is of a landing area of the unmanned aerial vehicle and collected by the image collection apparatus and a flight parameter of the unmanned aerial vehicle;
and
a vision chip, configured to:
perform image processing on the image that is of the landing area and collected by the image collection apparatus, and determine, with reference to the flight parameter obtained by the flight control chip, whether the landing area has the water surface ripple.
