Abstract: Example computer-implemented methods and systems for detecting and removing map artifacts are disclosed. One example computer-implemented method includes obtaining a magnetic map of a region. One or more areas in the magnetic map are determined based on a first machine learning model, where each of the one or more areas includes one or more artifacts in the magnetic map. The one or more areas are determined by generating, based on the first machine learning model and the magnetic map, a second map by the first machine learning model, and comparing the second map with the magnetic map. The one or more artifacts in each of the one or more areas are removed from the magnetic map.

Abstract: Systems and techniques for determining predicted object trajectories are disclosed. A vehicle computing system determines an initial predicted trajectory for an object detected in the environment and determine a predicted location for the object at the endpoint of the trajectory. Using a feature map of the environment, the vehicle computing system refines endpoint location based on a context for the endpoint. The system then determines a middle point of the trajectory based on the refined endpoint location and refines the middle location further based on the context for that location. The system iteratively uses one or more subsequent intermediate points and contexts along the trajectory for further location refinement(s) to generate a refined predicted object trajectory for the object and to determine trajectories for controlling a vehicle.

Abstract: Techniques for reducing latency associated with temporal sensor data processing. The techniques may include determining a region of interest within a field of view of a temporal sensor (e.g., rotating lidar sensor, rolling shutter camera, etc.). Based at least in part on determining the region of interest, an azimuth angle associated with a partial scan of the temporal sensor may be determined such that the region of interest is disposed within the azimuth angle. The techniques may also include receiving sensor data from the temporal sensor and determining whether the sensor data corresponds with the azimuth angle/region of interest. Based at least in part on a determination that the sensor data corresponding with the azimuth angle/region of interest has been received, the sensor data may be processed prior to at least one of receiving additional sensor data or a completion of a full scan by the temporal sensor.

Abstract: The present invention provides a method for imparting unique identifiers that do not overlap each other to individual position spaces in the case of latitude and longitude information or even in the case of height information also included in addition thereto. A longitude line passing through the coordinate origin is divided by the length of one side of a unit grid, and a latitude value inside unit grids is calculated. An accumulated error is calculated in a case where latitude values inside the unit grids are accumulated for one round in a longitude line direction of a celestial body, and an error per unit grid is calculated based on the calculated accumulated error. The number of unit grids included in one block in the longitude line direction is specified so that a reference error per block is equal to or smaller than one thousandth of the accumulated error, and thus a reference latitude is set.

Abstract: Whenever an avionics computer system receives a flight plan, the avionics computer system performs rules-based conformity checks with respect to a predefine set of rules/thresholds. The rules may be general aviation best practices (no rate of elevation change beyond some threshold, no single change in direction beyond some threshold, etc.) or specific to the aircraft (no violation of an operational ceiling, no violation of some defined fuel reserve, etc.). Violations of the rules and criteria are communicated to crew members via visual indicia of such violations, including the relative severity.
