Längenmessung in Stereobildern

Research output: ThesisMaster's Thesis

Abstract

Abstract Computer vision is an interesting and fast growing topic and deals with the 3D-reconstruction of natural pictures. There are a lot of applications, research papers, algorithms and programs for this topic available. In computer vision stereo-camerasystems are used. Depending on the eld of application (close-up range or aerial photograph) di erent considerations have to be taken. In the company arsenal research the road-measuring vehicle RoadSTAR was enhanced with two digital video cameras, which record the front view of the street. In the postprocessing stereo pictures can be extracted from the videos. In these stereo pictures distance measurements of objects (e.g. height of a bridge or width of a road) in a distance up to 30 m should be possible. Within this master thesis the basic theory of measuring in stereopictures is developed. In the practical execution the camera calibration, stereo calibration, a few factors on the accuracy, the measurement software and the rst results of distance measurements are described. In the conclusion the usability of the stereo-camerasystem is assessed and it is discussed which further requirements have to be ful lled to create a system, which can be used for distance measurements in a close-up range.
