This article deals with practical examples of the applications of modern tachymeters in the determination of the nonverticality of high industrial chimneys, as an alternative to the classic methods. The possibility of a reflectorless measuring mode to determine the point cloud at the chimney's circumference is described. Using these points, we are able to model the chimney as a mathematically correct body using the least squares adjustment method. Subsequently, the unknown nonverticality of the chimney is determined as the deviation of the primary axis of the modelled body from the vertical.

Abstract

V članku je obravnavan praktičen primer uporabe aplikacij sodobnega tahimetra pri določevanju nevertikalnosti visokih industrijskih dimnikov kot alternativa klasičnemu načinu določitve. Opisana je možnost merjenja točk brez uporabe reflektorja, s čimer na obodu dimnika določimo množico točk. Na njihovi podlagi lahko modeliramo dimnik kot pravilno matematično telo v prostoru z uporabo izravnave po metodi najmanjših kvadratov. Nevertikalnost dimnika nato določimo kot odmik glavne osi modeliranega telesa od navpičnice.
