Abstract: According to some aspects of the disclosure, techniques for compression techniques for the radar data that can be used in real-time applications for automated or self-driving vehicles. One or more compression techniques can be selected and/or configured based on information regarding operational conditions provided by a central (vehicle) computer. Operational conditions can include environmental data (e.g., weather, traffic), processing capabilities, mode of operation, and more. Compression techniques can facilitate transport of compressed radar data from a radar sensor to the central computer for processing of the radar data for object detection, identification, positioning, etc.

Abstract: Techniques are provide for generating occupancy grids based on inputs from multiple heterogeneous sensors. An example method for generating an occupancy grid includes obtaining detection information from a plurality of heterogeneous sensors, generating a single measurement grid based on the detection information from the plurality of heterogeneous sensors, determining occupancy probabilities for a plurality of cells in the single measurement grid, and outputting the occupancy grid based at least in part on the occupancy probabilities.

Abstract: In some aspects, a device may receive sensor data associated with a vehicle and a set of frames. The device may aggregate, using a first pose, the sensor data associated with the set of frames to generate an aggregated frame, wherein the aggregated frame is associated with a set of cells. The device may obtain an indication of a respective occupancy label for each cell from the set of cells, wherein the respective occupancy label includes a first occupancy label or a second occupancy label, and wherein a subset of cells from the set of cells are associated with the first occupancy label. The device may train, using data associated with the aggregated frame, a machine learning model to generate an occupancy grid, based on a loss function that only calculates a loss for respective cells from the subset of cells. Numerous other aspects are described.

Abstract: Techniques for determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle can include monitoring the primary mode of RF communication to ensure it is effectively communicating and, if not, intelligently selecting a backup communication mode comprising one or more other sensors and/or systems of the vehicle. The selection of the backup communication mode may take into account various factors that can affect the various modes of communication from which the backup communication mode is selected.

Abstract: System and method for processing a camera frame in a mobile device by partitioning the camera frame into different sections based on the distance from a vehicle to each of the sections and the required resolution of each of the sections. A mobile device comprises: a memory; a processor communicatively coupled to the memory, the processor configured to: receive a camera frame from a camera mounted on a vehicle traveling on a road; determine a drivable path of the vehicle; project the drivable path onto the camera frame; partition a part of the camera frame containing the drivable path into at least one section based on a distance from the vehicle to each of the at least one section; and determine a required resolution of each of the at least one section based on the distance from the vehicle to each of the at least one section.

Abstract: In some aspects, a system may receive, from a first one-dimensional radar array, first information based at least in part on first reflections associated with an azimuthal plane. The system may further receive, from a second one-dimensional radar array, second information based at least in part on second reflections associated with an elevation plane. Accordingly, the system may detect an object based at least in part on the first information and may determine an elevation associated with the object based at least in part on the second information. Numerous other aspects are described.

Abstract: A method includes, by a mobile device, receiving a Global Navigation Satellite System (GNSS) signal, and receiving, from a wireless device, via a PC5 interface, a message including a location of a reference structure, a calculated location of the mobile device, or a combination thereof. The method also includes determine whether the GNSS signal is a spoofing signal based on: a spoof indication of the GNSS signal, and whether a difference between a location of the mobile device determined based on the GNSS signal and one of the location of the reference structure, the calculated location of the mobile device, or a location of the mobile device determined based on the location of the reference structure is greater than a threshold value.

Abstract: The calibration of a vehicle sensor can be conducted based on communication between vehicles. A first vehicle needing sensor calibration can receive calibration information from a second vehicle, indicating the location of a calibration marker at one or more times. The first vehicle can then compare the calibration information with measurement information of the calibration marker made by a sensor, and recalibrate the sensor based on a comparison of the calibration information and measurement information. According to some embodiments, vehicles may leverage existing vehicle-to-vehicle communications (e.g., Cellular vehicle-to-everything (V2X) communication) to broadcast calibration capabilities.

Abstract: Apparatus and methods are disclosed for communicating between distributed automotive sensors, including radar sensors, wherein sensors transmit a synchronization (SYNC) signal, each SYNC signal transmitted via a substantially equal-length fiber optic link corresponding with each sensor. A central node receives the SYNC signals via the fiber optic links corresponding with each of the sensors and determines a master SYNC signal based on the received SYNC signals. The central node then transmits the master SYNC signal via the fiber optic links to the sensors, which receive the master SYNC signal and transmit, via fiber optic link, sensor data synchronized in accordance with the master SYNC signal. The synchronized sensor data are received at the central node and coherently aggregated, and transmitted to a compute node for post-processing. For radar data, the post-processing may include determination of an angular position of an object within detection range of at least two radar sensors.
