Autonomous machine navigation in lowlight conditions

An autonomous machine comprising:

• a housing coupled to a maintenance implement;
• a propulsion system including at least one motor;
• at least one camera adapted to record images in one or more light conditions;
• and
• a controller operably coupled to the at least one camera and the propulsion system, the controller adapted to perform:
• while the autonomous machine is moving at a first speed, determining that a localization update is requested by a navigation system of the autonomous machine;
• while the autonomous machine is moving at the first speed, detecting a lowlight condition;
• stopping the autonomous machine or slowing the autonomous machine to a second speed less than the first speed in response to detecting the lowlight condition and determining that a localization update is requested;
• while the autonomous machine is stopped or moving at the second speed, using an updated camera capture parameter for capturing a subsequent localization image using the camera;
• and
• using the subsequent localization image to perform the requested localization update.
