Abstract: Various aspects of the present disclosure generally relate to sensor targets. In some aspects, a method may include obtaining a detection resolution of a sensor that is to detect a target on a roadway; obtaining a designated speed limit of the roadway; estimating an exposure time of the target based on the detection resolution and the designated speed limit; determining, based on the exposure time, a target dimension of the target and a quantity of surface depths of the target; generating a code for the target based on the quantity of surface depths, wherein the code corresponds to a physical configuration of the target; and storing, in a mapping associated with the sensor, the code in association with the target to permit the target to be identified by the sensor. Numerous other aspects are provided.

Abstract: Disclosed herein are techniques for measuring a reference beam and a corresponding returned beam from a target in a measurement system using a single sensor array. The system is configured such that the location of the reference beam is space apart from the location of the returned beam on the sensor array. A first set of sensor elements on the sensor array corresponding to the reference beam is dynamically activated based on a laser beam scanning control signal. The detection signal from the first set of sensor elements is used to determine a location and/or a pattern of the reference beam, which are then used to estimate a location and/or a pattern of the corresponding returned beam on the same sensor array and dynamically select and activate a second set of sensor elements on the sensor array based on the estimated location and/or pattern of the corresponding returned beam.

Abstract: A light detection and ranging (LIDAR) apparatus includes dual beam scanners with dual beam steering. A first beam scanner in the LIDAR apparatus scans a wider area in one or more of a first plurality of scan patterns, and a second beam scanner in the LIDAR apparatus scans a narrower area in one or more of a second plurality of scan patterns different from the first plurality of scan patterns.

Abstract: Methods, systems, computer-readable media, and apparatuses for multi-tier light-based ranging are presented. One example method includes determining a first operating environment; selecting a first set of laser emitters from a plurality of sets of laser emitters based on the first operating environment, the first set of laser emitters having a first angular FOV and a first effective range; detecting one or more objects within the first angular FOV based on detected reflected laser light; determining a second operating environment different from the first operating environment; selecting a second set of laser emitters from the plurality of sets of laser emitters based on the second operating environment, the second set of laser emitters having a second angular FOV narrower than the first angular FOV and a second effective range greater than the first effective range; and detecting one or more objects within the second angular FOV based on detected reflected laser light.

Abstract: The present disclosure generally relates to an object detection system. For example, aspects of the present disclosure relate to systems and techniques for performing object detection using sensor information, such as elevation and/or velocity information from one or more light-based sensors. One example apparatus generally includes one or more processors operably configured to: obtain sensor information indicating at least two objects in an environment; determine at least one of a velocity or an elevation associated with each object of the at least two objects; consolidate the at least two objects into a common object based on the at least one of the velocity or the elevation; and output an indication of the common object.

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: In some aspects, a device may receive point data associated with a cell of an occupancy grid for controlling a vehicle. The device may determine, based on the point data, a characteristic of the cell that is associated with an occupancy probability of the cell, wherein the occupancy probability is determined according to a first technique based on the point data. The device may configure, based on the characteristic, the occupancy probability for the cell, within the occupancy grid, according to a second technique. 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: 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.

Abstract: A method and electronic device for selectively obtaining depth information at locations within a scene are described. Image content analysis is performed on a received image of the scene. Locations within the image to obtain depth information within the scene are determined based on the image analysis. The locations are provided to a LIDAR (light+radar) unit to selectively obtain depth information at the scene locations. The depth information is received from the LIDAR unit and a second image analysis is performed on a second image. The second image analysis is based on the image content of the second image and the received depth information. Updated locations based on the second image analysis may be provided to the LIDAR unit to obtain updated depth information.
