Photogrammetric capture and data processing for generating a 3D model of a traffic accident scene

摘要

Photogrammetry is a science, used in many different areas. In this thesis, its application in documentation of traffic accidents is presented, where a 3D model of the scene is generated from photos. The working process includes surveying measurements, taking photos of the calibration field and the traffic accident scene, photogrammetric measurements and generation of a 3D model. The first part introduces the theory about this area and presents the experience about this work in Slovenia and around the world. Briefly is presented also the use of terrestrial laser scanning, by means of examples. The thesis is mostly about the presentation and description of field work and phases for creating the final three-dimensional model of a traffic accident scene. There is also a detailed description of work, done in the PhotoModeler program, which I used in my practical example.
