This bachelor thesis is discussing The effect of using photogrammetry on the accuracy of a handheld laser scanner. Aim of the work is to determine, how much will the omission of photogrammetry impact the accuracy of data acquired by the handheld laser scanner and what other phenomena can occur by omitting the photogrammetry preparations. The goals were reached by analysing data of multiple measurements of two larger-sized objects. The acquired data were evaluated statistically for better reliability of made conclusions. The outcome was according to expectations, there were made conclusions about the influence of using the photogrammetric method on the accuracy of a handheld laser scanner. A comparison was made for marker data, mesh data and trends influencing the accuracy of measurements. Using photogrammetry, the results were up to 42,7 times more accurate in case of marker data. In case of mesh data, the results were up to 13,0 times more accurate. Thanks to this thesis a reader can have an idea about whether the use of photogrammetry method is or isn’t necessary to reach the desired accuracy, eventually what kind of undesired side-effects can occur without the use of photogrammetry.
