Abstract

<p>Accurate measurement of the shape of road surfaces is essential in pavement work. Recently, a mobile laser scanner has been used to facilitate pavement measurement. For localization purposes, an automatic tracking total station (ATTS) and an inertial measurement unit (IMU) are required. To achieve sufficient accuracy, a sophisticated IMU must be used ; increases the cost associated with the measurement process. In this report, a novel mobile camera localization method is proposed that utilizes an ATTS is proposed. This method can facilitate accurate estimation of a camera pose using few ground control points, which enables low-cost photogrammetry-based measurements. A prototype of the proposed system was built, and it was experimentally demonstrated that the localization method is sufficiently accurate for pavement management.</p>
