Abstract: A method and device for aerial vehicle-based image projection, and an aerial vehicle are provided. The method comprises adjusting a position of the aerial vehicle to a projection-permitted position if an image projection event for the aerial vehicle is detected, triggering a projection module of the aerial vehicle to project an image. Adjusting the position of the aerial vehicle comprises adjusting the position of the aerial vehicle based on an obstacle image captured in a projecting direction of the projection module.

Abstract: A gas leakage treatment method includes detecting a target gas concentration of a target gas in an environment at a corresponding position of a gas delivery pipeline in a process of moving along the gas delivery pipeline. The method further includes, if the target gas concentration is greater than a preset concentration threshold, determining that gas leakage occurs and performing a gas leakage treatment operation.
