Abstract: In various examples, techniques for generating vocabulary dictionary for localization in autonomous and/or semi-autonomous systems and applications are described herein. Systems and methods may use multiple clustering techniques—such as K-Means Clustering and/or Balanced Iterative Reducing and Clustering using Hierarchies (BIRCH)—to initially generate and/or update a vocabulary dictionary corresponding to an environment. For instance, using the clustering techniques, extracted features from initial images of a localization map may be used to generate a vocabulary tree corresponding to the vocabulary dictionary. Additionally, and again using the clustering techniques, extracted features from new images of the localization map may be used to update the vocabulary tree.

Abstract: In various examples, stereo image localization for autonomous and/or semi-autonomous systems and applications is described herein. Systems and methods may perform localization using two images from a stereo camera along with a map image from a localization map. For instance, a respective relative pose between each of the images and the map image may be determined along with a relative pose between the images. The relative poses may then be used to determine a predicted pose—such as an estimated rotation and/or an estimated translation—between one of the images and the map image. Additionally, the predicted pose may be refined using one or more optimization techniques, such as by minimizing distances between feature points of the images and epipolar lines associated with the points. The refined pose between the images may then be used to determine a localized pose of the machine within the environment.

Abstract: The technology is directed to a system that allocates a frequency band to a satellite within a non-terrestrial network (NTN) and determines the available channel bandwidth for data transmissions within that frequency band. If the satellite detects an absence of a Radio Resource Control (RRC) connection between the satellite and at least one terminal device within the geographical location, which indicates a lack of active communication with the terminal devices, the satellite responds by transmitting signals at a reduced transmit power and within a portion of the available channel bandwidth towards the geographical location. The RRC connection can be managed by an RRC protocol.
