VISUAL LOCALIZATION AND FEATURE DETECTION FOR A WORK VEHICLE IMPLEMENT TRACKING SYSTEM

A method for tracking a movable implement of a work vehicle. The method comprises the steps of 1.) accessing images during movement of the work vehicle providing a view onto an environment and at least part of the implement, 2.) providing by a feature tracking algorithm a 3D environment model and referencing of the sensor pose to the 3D environment model, 3.) tracking implement features at different poses of the implement and, determining implement tracking data providing positional and arrangement information for the implement features, 4.) accessing benchmark information providing a real distance between two benchmark points, 5.) using the benchmark information to provide the implement tracking data with absolute scale information, and 6.) using the implement tracking data for the tracking of the implement.
