Determination of verticality and straightness of blind shaft using digital photogrammetry

Abstract

The contribution results from the GA CR 105/09/P212 grant solution aiming at making a proposal of the measurement methodology and the data processing procedure for vertical mine workings. Resulting from the tests performed in a laboratory blind shaft n the building of the Rector's Office at the VSB-Technical University of Ostrava, a surveying rig, having been used till now, will be adjusted for measuring vertical mine workings using the digital photogrammetric method. Taking digital images, a lot of means will occur to create applications for processing and automatic evaluation of verticality and straightness of individual objects of interest, or 3D modelling or visualization of shaft. Based on the results a mean error of the proposed measuring method will then be determined.
