Abstract | The semantic SLAM (simultaneous localization and mapping) system is an indispensable module for autonomous indoor parking. Monocular and binocular visual cameras constitute the basic configuration to build such a system. Features used in existing SLAM systems are often dynamically movable, blurred and repetitively textured. By contrast, semantic features on the ground are more stable and consistent in the indoor parking environment. Due to their inabilities to perceive salient features on the ground, existing SLAM systems are prone to tracking loss during navigation. Therefore, a surround-view camera system capturing images from a top-down viewpoint is necessarily called for. To this end, this paper proposes a novel tightly-coupled semantic SLAM system by integrating Visual, Inertial, and Surround-view sensors, VIS SLAM for short, for autonomous indoor parking. In VIS SLAM, apart from low-level visual features and IMU (inertial measurement unit) motion data, parking-slots in surround-view images are also detected and geometrically associated, forming semantic constraints. Specifically, each parking-slot can impose a surround-view constraint that can be split into an adjacency term and a registration term. The former pre-defines the position of each individual parking-slot subject to whether it has an adjacent neighbor. The latter further constrains by registering between each observed parking-slot and its position in the world coordinate system. To validate the effectiveness and efficiency of VIS SLAM, a large-scale dataset composed of synchronous multi-sensor data collected from typical indoor parking sites is established, which is the first of its kind. The collected dataset has been made publicly available at https://cslinzhang.github.io/VISSLAM/. |
