Mobile Multi-camera System Performance for Photogrammetric Road Surface 3D Measurements – Assessment the Effect of Driving Speed

Abstract. Mobile mapping systems usually include cameras designed for 360° imaging and laser scanning point cloud coloring. However, the multi-camera systems are rarely optimized for producing photogrammetric image-based point clouds in road environments. In this study, we built a mobile 5-camera system and assessed it...
