Robust All-season LiDAR Positioning System (LPS)
Most LiDAR-based positioning systems are designed for indoor use and fail when the environment changes extensively, which is rare indoors. In outdoor use, however, it is important that the local location can be determined precisely even when the environment changes. Just by changing the vegetation, by pruning trees and mowing grass, prominent points of the map may be obscured and new ones will be created. A LiDAR-based outoor positioning system must be able to detect and handle all of this over seasons. Our owlLPS is designed for this special "year-round capability".
Features:
- requires only a low-cost LiDAR (e.g. Livox MID-360 or LSLIDAR-C16)
- high-precision 3D LiDAR odometry (typical +/- 2cm)
- outdoor and indoor across several floors (small and large 3D areas with thousands of square meters, across floors)
- robust localization system (localization works between seasons, e.g. localization at winter time against a summer map and vice versa with typical localization accuracy +/-10cm in changing outdoor environments and +/-2 cm in static environments)
- optionally, GPS-RTK can be added to improve localization performance in very open areas (>100m) with no objects in the environment (alternatively, objects like traffic cones can be added to very open areas for LiDAR-only localization)
- based on open source code (robotic operating system ROS)
