Document Type and Number:
WIPO Patent Application WO/2018/023854
Kind Code:
A1
Abstract:
An unmanned aerial vehicle-based external wall spray printing system and a spraying method therefor, wherein a spray nozzle is disposed on the unmanned aerial vehicle. The method comprises the following steps: A. controlling an unmanned aerial vehicle to fly along edges of an external wall, and measure an area to be sprayed according to a flight trajectory; B. using the measured to-be-sprayed area to calculate a spray trajectory for a pattern to be sprayed on the to-be-sprayed area, then acquiring various positioning coordinates on the spray trajectory, and establishing corresponding relationships between the respective positioning coordinates and spray feature data; C. controlling the unmanned aerial vehicle to fly to corresponding positions of the to-be-sprayed area in accordance with the respective positioning coordinates of the spray trajectory, and calling the corresponding spray feature data to control the nozzle to spray a coating material, thus completing spraying the pattern. The spray printing system and method can rapidly spray and print an advertisement on a wall by using an unmanned aerial vehicle, thereby reducing the labor intensity and construction difficulty for construction workers.
