Master’s thesis presents review and assessment of methods for geometric data acquisition of
buildings envelope for program epiqr® and 3D visualization.
First, theoretical part, of the thesis is an overview of existing spatial data, which could be used
in order to extract geometric data of building’s envelope and an overview of existing
technologies and methods for geometric data acquisition and 3D modeling. These
technologies and methods are compared and evaluated according to epiqr® methodology. As
a result of theoretical part, 5 different approaches for geometric data acquisition and 3D
modeling of building’s envelope are proposed.
Second, practical part, of the thesis describes practical tests of proposed approaches. These
were tested on 3 test buildings, which differ in size, shape and surrounding occlusions, which
might prevent data acquisition. Depending on the used approach, tests included existing
spatial data collection, planning and execution of on-site surveying, processing of obtained
data, 3D modeling and determination of geometric data of building’s envelope. Within each
test, the time spent to finish individual phase has been measured. Proposed approaches are
evaluated from the perspective of geometrical accuracy, time, effort and added value.
Geometrical accuracy is determined based on comparison of geometrical data obtained using
proposed approaches and high accuracy reference measurements. Based on the experiment
results, suitability of proposed approaches for epiqr® program and 3D visualization is given.
