Abstract
Techniques for determining errors or drifts between maps used for updating maps and/or controlling a system which uses the map. In some examples, a first, global, map may be received or determined. Sensor data may then be used to localize a system with respect to the first map and to generate a first trajectory relative to the first map. The sensor data may be used to create a second map and a second trajectory for navigating the system relative to the second map. Differences between the first and second trajectories (or portions thereof), when compared in a common reference frame, may be used as an indication of drift between various processes or errors in the maps and, subsequently, be used for updating the first map and/or controlling the system.
