AUTONOMOUS MACHINE NAVIGATION IN VARIOUS LIGHTING ENVIRONMENTS

Training an autonomous machine in a work region for navigation in various lighting conditions includes determining a feature detection range based on an environmental lighting parameter, determining a feature detection score for each of one or more positions in the containment zone based on the feature detection range, determining one or more localizable positions in the containment zone based on the corresponding feature detection scores, and updating the navigation map to include a localization region within the containment zone based on the one or more localizable positions. Navigation may use one or more of an uncertainty area, the localization region, and one or more buffer zones to navigate based on lighting conditions.
