Abstract. Mobile multicam photogrammetry systems offer a number of advantages over other 3d imaging modalities, including rapid acquisition speed, low cost sensors, and the availability of mature open-source software systems for photogrammetric alignment and reconstruction.. Through a number of case studies we compare the Looq, a home-grown GPS enabled multi-cam mobile mapping system, to colocated models from terrestrial photogrammetry, aerial photogrammetry, two terrestrial LiDAR systems, and two SLAM LiDAR systems. We evaluate these systems across varied urban and natural environments, in GPS enabled and denied environments, tight interior spaces, and open landscapes in Europe and North America. The comparative performance of these systems is described qualitatively and quantitatively.
