Abstract: aspects and implementations of the present disclosure address shortcomings of the existing technology by enabling doppler-assisted segmentation of points in a point cloud for efficient object identification and tracking in autonomous vehicle (av) applications, by: obtaining, by a sensing system of the av, a plurality of return points comprising one or more velocity values and one or more coordinates of a reflecting region that reflects a signal emitted by the sensing system, the one or more velocity values and the one or more coordinates obtained for the same instance of time, identifying that the set of the return points is associated with an object in an environment, and causing a driving path of the av to be determined in view of the object.

CPC Code(s):
Abstract: described examples relate to an apparatus comprising a memory for storing a sequence of image frames and at least one processor. the at least one processor may be configured to receive a first image frame of a sequence of image frames from an image capture device and select a first portion of a first image frame. the at least one processor may also be configured to obtain alignment information and determine a first portion and a second portion of a second image frame based on the alignment information. further, the at least one processor may be configured to determine a bounding region within the second image frame and fetch image data corresponding to the bounding region of the second image frame from memory. in some examples, the first image frame may comprise a base image and the second image frame may comprise an alternative image frame. further, the first image frame may comprise any one of the image frames of the sequence of image frames.

CPC Code(s):
Abstract: the technology relates to approaches for determining appropriate stopping locations at intersections for vehicles operating in a self-driving mode. while many intersections have stop lines painted on the roadway, many others have no such lines. even if a stop line is present, the physical location may not match what is in store map data, which may be out of date due to construction or line repainting. aspects of the technology employ a neural network that utilizes input training data and detected sensor data to perform classification, localization and uncertain estimation processes. based on these processes, the system is able to evaluate distribution information for possible stop locations. the vehicle uses such information to determine an optimal stop point, which may or may not correspond to a stop line in the map data. this information is also used to update the existing map data, which can be shared with other vehicles.
