Simultaneous localization and mapping (SLAM) systems have made 3D mapping possible indoors in addition to outdoors. Coloured point clouds can be obtained using both survey-grade systems, such as vehicle-mounted mobile laser scanning, and consumer technologies, such as Lidar sensors in mobile devices. Thanks to the continuing advancement of 3D mapping technology, the efficiency of obtaining 3D point clouds has never been higher. ![]() With the development of computer hardware solutions and game engines that are compatible with point clouds, point cloud visualization in VR has become increasingly attainable – and therefore relevant for geomatics as well. The immersive visualization offered by new VR techniques is well suited for geometrically complex datasets, such as indoor point clouds. The point clouds themselves are efficient to produce with 3D mapping methods. Direct utilization of dense, coloured point clouds in a virtual world is motivated by many reasons.
