Paper Abstract

At The Center for Mapping of The Ohio State University, a mobile mapping system was developed. By integrating the global positioning system (GPS) with a stereo vision system, the global coordinates of any point in the field of view of the cameras can be obtained. The calibration of cameras was done by using the bundle adjustment in a test field of retro reflective targets. The image coordinates are measured automatically by means of the center of gravity, the identification of points is also performed automatically using the space resection. As the stereo cameras are mounted on a stationary platform, relative orientation constraints are applied in the calibration. As a result, the number of required observations is reduced and a stable calibration of the stereo vision system is achieved. The modifications to the standard bundle solution are presented, as well as the positioning accuracy of the calibrated system.
