Abstract
A system for mapping and localization includes first and second robotic devices and fiducial tags placed at predetermined positions of an environment. The quality of the first robotic device is better than the second robotic device. The first robotic device prepares a high resolution multilayer map, and the second robotic device uses the multilayer map for fast and accurate localization. The first robotic device has a visual sensor and a light detection and ranging (LIDAR) device, and is configured to prepare the multilayer map by: constructing a feature point cloud layer of the environment using images captured by the visual sensor; building a tag layer comprising identifications and locations of the tags; constructing an occupancy map using LIDAR scans; and forming the multilayer map having the feature point cloud layer, the tag layer, and the occupancy map layer, which share the same coordinate system.
