Mobile Digital Cameras for As-Built Surveys of Roadside Features

In recent years, a mobile video-logging system (MVS), consisting of a van equipped with a high-resolution digital camera, global positioning system (GPS), and an inertial navigation system (INS), has been used for capturing roadside features imagery along highways and freeways. This article describes a method for determining the three-dimensional locations of roadside features appearing on multiple sequential images captured using an MVS without any ground control. The digital camera was calibrated using a special three-dimensional calibration range and Calib software to simultaneously determine the interior and exterior orientation elements on a local system. The relative locations were transformed to the absolute locations using the locations of the camera's exposure stations from the Global Positioning System. The relative accuracy of the locations obtained was 5 cm, and absolute accuracy using the code phase kinematic Global Positioning System was 2 m. The authors also discuss the two-dimensional geographic information system, three-dimensional geographic information system, and virtual reality created for three test sites using the imagery from the MVS.
