1. Introduction and Related WorkVisual localization and dense 3D reconstruction are high-demand research areas, forming the core technology of a broad range of indoor and outdoor applications. Compared to using a single sensor, multiple sensor-based Simultaneous Localization and Mapping (SLAM) approaches are more robust, as the sensors can be used in a complementary manner for motion estimation.
