Autonomous work vehicle using image-based localization

An autonomous work vehicle, comprising:

• two or more sensors operable to generate two or more respective independent localization data, a first localization data of the two or more independent localization data comprising a first image of a scene surrounding the autonomous work vehicle from a first camera;
• and
• a controller coupled to the two or more sensors and having access to a stored three-dimensional point cloud (3DPC) that represents a work region of the autonomous work vehicle, the controller operable to:
• receive a signal to start an autonomous operation mode of the autonomous work vehicle within the work region;
• in response to the signal, perform a localization process comprising:
• generating the two or more independent localization data;
• determining a first pose estimate of a current pose of the autonomous work vehicle via the 3DPC using the first localization data;
• determining a second pose estimate of the current pose of the autonomous work vehicle using a second localization data of the two or more independent localization data;
• and
• determining a validated pose when the first pose estimate of the current pose and the second pose estimate of the current pose are separated by less than a threshold amount, wherein operations of the autonomous vehicle are not allowed if the first and second pose estimates of the current pose are separated by more than the threshold amount.
