Abstract

The invention discloses a method and system for detecting house facade hollowing through an unmanned aerial vehicle. The method comprises the following steps of a space coordinate system being established; selecting a detection point; detecting parameters; preliminary comparison; performing accurate shooting; comparing again; empty drum confirmation. According to the method for detecting the hollowing of the outer vertical surface of the house through the unmanned aerial vehicle, 1, the unmanned aerial vehicle is controlled to replace manpower to shoot the exterior of the house, so house detection difficulty is greatly reduced, and meanwhile, detection precision and detection efficiency can also be improved; 2, the shot house three-dimensional image is compared with house external data, so that the error occurrence position can be quickly obtained, the error occurrence position can be conveniently obtained, and the manual troubleshooting range is reduced; and 4, the obtained accurate three-dimensional image is compared with a common object image in a database, so the investigation range can be further expanded, and investigation difficulty and workload are improved.

Description

technical field

[0001] The invention relates to the technical field of hollow drum detection, in particular to a method and system for detecting hollow drums on house facades by means of unmanned aerial vehicles. Background technique

[0002] More and more houses have been built in our country. Since 2007, the country began to promote the external wall insulation system to achieve the effect of building energy saving and heat preservation. At present, the design service life of building structures in my country is generally 50 years, while the design service life of external wall insulation is only 25 years. Due to the short promotion and use of external wall insulation, there are few related studies, and the construction quality is difficult to guarantee. In recent years, quality problems such as cracking, falling off, water seepage, and decline in thermal insulation performance have occurred in external wall insulation systems in various places. demand is increasing.
