Title: Innovations of Robert Alexander Hewitt
Introduction
Robert Alexander Hewitt is an accomplished inventor based in Tujunga, California. He has made significant contributions to the field of navigation technology, particularly in the context of unmanned aerial systems and vision-based navigation. With a total of 2 patents, his work showcases innovative methods that enhance the capabilities of autonomous vehicles.
Latest Patents
Hewitt's latest patents include a "Minimal state augmentation algorithm for stereo-vision-based navigation." This method allows for vision-based navigation on a moving vehicle by utilizing reference images with associated depth information. The process involves detecting 2D features in base frames and tracking them in subsequent search frames. A depth processor reconstructs the depth and 3D position of each feature, while a track manager maintains a database of 2D and 3D coordinates. Additionally, a state manager constructs a filter state vector to correct inertial error drift.
Another notable patent is the "Method and system for on-board localization." This innovation provides a framework for localization in unmanned aerial systems (UAS). It generates a map image of the area being overflown and processes it to create an abstract map. The UAS is then localized by acquiring camera images during flight, detecting features, and refining its 3D pose for autonomous navigation.
