Building inspection of buildings and structures by means of multicopters and photogrammetry

The article presents the method of visual inspection and control of buildings and constructions by means of aerial photograph from the unmanned aerial vehicle. Constant improvement of programs for photogrammetric processing seriously expands possibilities of this method and allows apply it in various ways. The purpose of the article is to prove the applicability of the method of photogrammetry in a survey of buildings and structures, as well as in construction control. Aerial photograph and creation of virtual three-dimensional model of buildings and structures finds application in many stages of construction, repair and reconstruction of buildings. Flight of the building and shooting from air allow examining inaccessible sites, and systematization of the finished shooting material gives new opportunities at identification of defects and damages. Besides, periodical continuous shooting of a construction can be useful at long monitoring of his state. The practical results of using this method of construction control given in the article make it possible to say that photogrammetric allows to receive the results suitable as for measurements of the building with high precision, and for check of construction works. The considered technique is modern and relevant in the sphere of construction control and also qualitatively expands an arsenal of specialists in inspection and supervision of construction.
