UAV-based paint repair method for super-large high-rise buildings

Abstract

The invention relates to an ultra-large high-rise building paint repairing method based on an unmanned aerial vehicle, and relates to the field of environmental protection. The method comprises the steps: determining an unmanned aerial vehicle takeoff point and a reference center; establishing a three-dimensional coordinate system, determining a flight path and flight parameters of the unmanned aerial vehicle; photographing a part, which does not need paint repairing, on the unmanned aerial vehicle in advance and acquiring a standard RGB value range; determining the position needing paint repairing on a high-rise building according to a video when the unmanned aerial vehicle flies; and making the unmanned aerial vehicle decelerate and capturing a real-time picture through the camera, and when an average RGB value of the picture is not within the standard RGB value range, getting ready to start paint repairing, adjusting a distance between the unmanned aerial vehicle and an outer wall of the high-rise building, and adjusting the balance of the unmanned aerial vehicle and carrying out paint repairing. The distance between the unmanned aerial vehicle and the outer wall of the high-rise building is preliminarily determined through the flight path, and then the distance between the unmanned aerial vehicle and the outer wall of the high-rise building is adjusted when the paint repairing is needed so that accuracy during paint spraying is enhanced.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an unmanned aerial vehicle-based paint repair method for super-large high-rise buildings. Background technique [0002] At present, after long-term use of super-large high-rise buildings, the phenomenon of paint falling off on the outer walls of high-rise buildings will occur, which will not only affect the appearance of high-rise buildings, but also affect the service life of high-rise buildings. Touch up paint. The prior art is to set up the staff to the position where the paint needs to be repaired by a ladder, and then paint the high-rise building with a paint brush or a paint spray gun. The above-mentioned prior art solutions are relatively low in security and have potential safety hazards. In the existing technology, spraying or spraying of objects (such as crops, high-voltage wires) by drones has been widely used, but there is no precedent for spraying or repainti...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: in the above-mentioned automatic spraying method of the drone, the flight trajectory of the drone is relatively single, and the green weighting is carried out on the basis of the RGB value of the acquired image to determine the spraying value that needs to be sprayed. Therefore, the above-mentioned UAV automatic spraying method applied to plant protection is not only not suitable for repainting high-rise buildings, but also has a single way between the measurement target and the UAV, which will make the UAV spray when painting. The location is not precise enough, so it needs to be improved
