Abstract: The present disclosure is directed to combining the strengths of different methods of analyzing collected sensor data to reduce the risk of an autonomous vehicle (AV) impacting an object. This may include combining data from sets of data that track movement of objects over time with instantaneously received sensor data based on a series of steps that include accessing data that tracks the motion of objects in the field of view of a sensing apparatus, receiving current sensor data that includes a component of current or instantaneous object motion, and generating a forecast of future motion of that object. This forecast may be based on an analysis that compares the data that tracks the motion of objects with the current sensor data as part of a process that generates a risk probability. When the risk probability meets or exceeds a threshold level, a corrective action may be initiated.

Abstract: The present disclosure is directed to combining the strengths of different methods of analyzing collected sensor data to updating a driving pattern of an automated vehicle (AV). This may include combining data from sets of data that track movement of objects over time with instantaneously received sensor data based on a series of steps that include accessing data that tracks the motion of objects in the field of view of a sensing apparatus, receiving current sensor data that includes a component of current or instantaneous object motion, and identifying whether controls of AV should be maintained or changed. When controls of the AV are maintained, an AV may be controlled to stay in driving in a same lane of a roadway at a same velocity. When controls of an AV are changed, changes may include applying, increasing a velocity, or altering the course of the AV.

Abstract: The present disclosure is directed to processing data associated with a non-radar type sensing device to identify data points associated with a radar type sensing device that are likely secondary radar reflections such that a processor of a sensing apparatus can direct processing resources to processing radar data that are associated with primary radar reflections. The receipt of secondary radar reflections may cause a processor of a sensing apparatus to identify that an object is located at a location when there is no object in that location. Because of this, methods and apparatus of the present disclosure identify and avoid processing radar data that are likely to be associated with a object that does not exist. Eliminating false radar data, therefore, can prevent a processor of a sensing apparats from performing unnecessary processing tasks and can help prevent that processor from making false determinations.

Abstract: The present disclosure is directed to focusing processing resources of a radar apparatus to radar data associated with specific locations around an autonomous vehicle (AV). Data associated with a type of sensing apparatus that is not a radar (e.g. a camera and/or a LiDAR apparatus) that tracks motion of specific objects around the AV may be used by a processor to identify specific sets of radar data to process. Locations associated with a specific set of tracked objects may be used to identify sets of received radar signals that will be processed by the radar apparatus. Radar signals received by the radar apparatus that are associated with locations that do not correspond to a location of a tracked object may be ignored by the radar apparatus to reduce a number of computational tasks that a processor of the radar apparatus must process.

Abstract: Depth data processing systems and methods are disclosed. A mapping system receives, from one or more depth sensors, depth sensor data that includes a plurality of points corresponding to an environment. The mapping system uses one or more trained machine learning models to perform semantic segmentation of the plurality of points, to classify a first subset of the points into a first category and to classify a second subset of the points into a second category. The mapping system clusters the plurality of points into a plurality of clusters based on the semantic segmentation. At least some of the first subset of the points are clustered into a first cluster and at least some of the second subset of the points are clustered into a second cluster. The mapping system generates a map of at least a portion of the environment based on the plurality of clusters.

Abstract: Ranging and detection data is processed to identify or correct for multipath reflection. A sensor point that represents a location of an object, the location based on an incidence of an electromagnetic wave received at a sensor is obtained. The first sensor point is determined to be a product of multipath reflection. A first point of reflection on a surface of a surface model is determined. The location of the first sensor point is corrected based on the first point of reflection on the surface of the surface model.
