TPS AND TLS LASER SCANNING FOR MEASURING THE INCLINATION OF TALL CHIMNEYS

Abstract

The verticality of tall chimneys needs to be accurately monitored. Vertical plumbing, the classic geodetic procedure for detecting the inclination has certain drawbacks and can be replaced by modern technology if necessary. It was proposed a more general and rigorous procedure. For the researching it was used laser scanning methods which result in point clouds. Data acquired with two types of laser scanners were fit to a cylinder using the least squares adjustment. The aim of the paper was also to point out the differences between the used technologies, the differences between the results as well as influences on the computed inclination of the chimney and its practical explanations.
