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.

First claim

What is claimed is:

1 . A method of image projection using an aerial vehicle, comprising:
adjusting a position of the aerial vehicle to a projection-permitted position if an image projection event for the aerial vehicle is detected; and triggering a projection module of the aerial vehicle to project an image, wherein 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.

2 . The method of claim 1 , further comprising, after adjusting the position of the aerial vehicle to the projection-permitted position:
recording position information of the projection-permitted position, the position information comprising coordinate information and altitude information; and obtaining coordinate data and altitude data of the aerial vehicle during the image projection, comparing the obtained coordinate data and altitude data with the coordinate information and the altitude information of the projection-permitted position, and adjusting the position of the aerial vehicle based on a comparison result to hold the aerial vehicle at the projection-permitted position.

3 . The method of claim 1 , wherein adjusting the position of the aerial vehicle to the projection-permitted position if the image projection event for the aerial vehicle is detected comprises:
adjusting the position of the aerial vehicle if the image projection event for the aerial vehicle is detected; detecting, at the adjusted position, whether there exists an obstacle satisfying a preset projection background condition; and if no obstacle satisfying the preset projection background condition exists, moving the aerial vehicle to a new position; repeating the detecting and moving until an obstacle satisfying the preset projection background condition is detected; and determining a position of the aerial vehicle as the projection-permitted position if there exists an obstacle satisfying the projection background condition, wherein the detected obstacle is an obstacle in the projecting direction of the projection module of the aerial vehicle.

4 . The method of claim 3 , wherein detecting whether there exists an obstacle satisfying the preset projection background condition comprises:
obtaining, at the adjusted position, edges of an obstacle, a distance from a point of the obstacle to the aerial vehicle, and an image containing the obstacle; determining whether the edges of the obstacle, the distance of the point of the obstacle, and a color and a texture of the obstacle in the image satisfy the preset projection background condition; and if the preset projection background condition is satisfied, determining that there is an obstacle satisfying the preset projection background condition.

5 . The method of claim 1 , further comprising:
using a sound collecting module of the aerial vehicle to collect an original sound signal if a recording operation is detected; filtering the collected original sound signal based on a preset sound frequency of a propeller, to obtain a sound signal; and storing the obtained sound signal or sending the obtained sound signal to a user terminal.

6 . An device for image projection using an aerial vehicle, comprising:
a position adjusting module configured to adjust a position of the aerial vehicle to a projection-permitted position when an image projection event for the aerial vehicle is detected; and a projection controlling module configured to trigger a projection module of the aerial vehicle to project an image, wherein the position adjusting module is further configured to adjust the position of the aerial vehicle based on an obstacle image captured in a projecting direction of the projection module when the image projection event for the aerial vehicle is detected.

7 . The device of claim 6 , further comprising:
a storage module configured to record position information of the projection-permitted position, the position information comprising coordinate information and altitude information, wherein the position adjusting module is further configured to obtain coordinate data and altitude data of the aerial vehicle during the image projection, compare the obtained coordinate data and altitude data with the coordinate information and the altitude information of the projection-permitted position, and adjust the position of the aerial vehicle based on a comparison result to hold the aerial vehicle at the projection-permitted position.

8 . The device of claim 6 , wherein the position adjusting module comprises:
an adjusting unit configured to adjust the position of the aerial vehicle if the image projection event for the aerial vehicle is detected; a detecting unit configured to detect, at the adjusted position, whether there exists an obstacle satisfying a preset projection background condition, and if no obstacle satisfying the preset projection background condition exists, notify the adjusting unit to move the aerial vehicle to a new position; and a determining unit configured to determine a position of the aerial vehicle as the projection-permitted position if there exists an obstacle satisfying the projection background condition, wherein the obstacle detected by the detecting unit is an obstacle in the projecting direction of the projection module of the aerial vehicle.

9 . The device of claim 8 , wherein the detecting unit is further configured to:
obtain, at the adjusted position, edges of an obstacle, a distance from a point of the obstacle to the aerial vehicle, and an image containing the obstacle, determine whether the edges of the obstacle, the distance of the point of the obstacle, and a color and a texture of the obstacle in the image satisfy the preset projection background condition and if the preset projection background condition is satisfied, determine that there exists an obstacle satisfying the preset projection background condition.

10 . The device of claim 6 , further comprising:
a record processing module configured to use a sound collecting module of the aerial vehicle to collect an original sound signal if a recording operation is detected, and filter the collected original sound signal based on a preset sound frequency of a propeller, to obtain a sound signal; and an outputting module configured to store the obtained sound signal or send the obtained sound signal to a user terminal.

11 . An aerial vehicle, comprising:
a carrier configured to carry an external projection device; and a controller configured to:
adjust a position of the aerial vehicle to a projection-permitted position if an image projection event for the aerial vehicle is detected, and
trigger the projection device carried by the carrier to project an image,
wherein 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 device.

12 . The aerial vehicle of claim 11 , wherein the controller is further configured to:
record position information of the projection-permitted position, position information comprising coordinate information and altitude information, obtain coordinate data and altitude data of the aerial vehicle during the image projection, compare the obtained coordinate data and altitude data of the aerial vehicle with the coordinate information and altitude information of the projection-permitted position, and adjust the position of the aerial vehicle based on a comparison result, such that the aerial vehicle is held at the projection-permitted position.
