Abstract

This diploma thesis deals with various principles of 3D data acquisition. It focuses on optical methods, which are described in more detail in this work. It is a method of laser triangulation, ie measuring distance using a projected laser beam, "Time of Flight" technology, which measures the flight time of light to the target and back and calculates the actual distance from the measured object, photogrammetry technology, which performs 3D reconstruction model from the taken photos. Part of the work is a practical verification of some optical scanning methods. The comparison of the obtained point clouds is performed using an application created in the LabVIEW graphical environment. Furthermore, the calibration and accuracy of scanning on various types of surfaces is verified using photogrammetry technology.
