Simultaneous Three-Dimensional Mapping and Geolocation of Road Surface
… that combines local road surface mapping and global camera localization. The local road surface is generated by structure from motion (SFM) with multiple views and optimized by Bundle Adjustment (BA). A system is developed for the global reconstruction of 3D road surface. Using the system, the …

Towards Observable Urban Visual SLAM
… acquisition. However, for applications in urban environments, where the camera-mounted vehicle moves along a straight line direction towards the road scene, a large number of features suffer difficulty in depth estimation due to their small parallax angles, as a result the classical V-SLAM …

3D sensing and mapping using mobile color and depth sensors
… denoise and calibrate time-of-flight based depth cameras. Our formulation is based on two key elements. We first use depth planarization in 3D to denoise the depth at each corner pixel. Thereafter, we use these improved depth measurements along with the corner pixel information to …

Semi-direct visual SLAM for stereo cameras: system design and validation
Simultaneous Localization and Mapping (SLAM) requires an autonomous vehicle in an unknown environment to learn about the environment, generates a map and localize itself at the same time. To solve this problem, various types of sensors are equipped to gather information. Nowadays, with the …
