    摘要: The present disclosure describes database systems and methods for retrieving data therefrom. In aspects, database system includes a binary storage component having a plurality of binary elements. Each binary element of the plurality of binary elements includes a first plurality of data fields ordered according to a binary data storage framework. The database system further includes a metadata component having a plurality of metadata elements. Each metadata element of the plurality of metadata elements includes a second plurality of data fields and a reference to at least one binary element. The metadata component may be configured to order the second plurality of data fields in each metadata element according to a metadata storage framework. The database system further includes an intermediate layer configured to adapt the binary data storage framework of the binary elements to the metadata storage framework of the metadata component.

    摘要: A light detection and ranging (LIDAR) device having a sensor for detecting input signals and an emitter for emitting output signals. A controller controls the emitter to emit output signals and reads the input signals from the sensor during a plurality of scan cycles. Each scan cycle is separated by a spacer period, and the controller is configured to vary the length of the spacer periods between the plurality of scan cycles. The LIDAR device may form part of a LIDAR system. Methods for reducing interference in a LIDAR system, and methods and software for controlling a LIDAR device are also disclosed.

    摘要: Methods, devices, systems, and computer program products for estimating object reflectivity in a light detection and ranging (LIDAR) system are disclosed. The method, for example, includes receiving LIDAR data for a plurality of LIDAR scan cycles. The method also includes generating a dataset from the LIDAR data by accumulating the recorded return signals over the plurality of scan cycles. A data feature associated with an object is identified in the dataset, and one or more parameters of the data feature are identified. An estimated reflectivity of the object may then be determined based on the one or more parameters.

    摘要: The techniques and systems herein enable ESA modification based on manual steering inputs. Specifically, a score is determined for a manual steering input to a host vehicle while an ESA is actively applying an ESA steering input to the host vehicle. The score quantifies an amount of additional steering input relative to the ESA steering input (e.g. additional steering angle, steering wheel torque). The ESA steering input is maintained, modified, or canceled based on the score. By doing so, the system is able to effectively adapt the ESA to the manual steering inputs thereby allowing for effective collision mitigation while ensuring that the vehicles operate as intended by the drivers.

    摘要: A method is provided for determining a mobility status of a target object located in an environment of a sensor configured to monitor a surrounding environment of a vehicle. According to the method, a detection angle of the target object is determined with respect to the sensor based on data acquired by the sensor, and an ideal beam vector for a stationary object is predicted based on the detection angle. The ideal beam vector and a measured beam vector obtained from the data acquired by the sensor are normalized, and a correlation of the normalized ideal beam vector and the normalized measured beam vector is determined. A score is determined based on the correlation of the normalized ideal and measured beam vectors and indicates whether the target object is stationary or moving.

    摘要: This document describes techniques, apparatuses, and systems for multi-channel joint interference mitigation. Radar radiation received by a radar system may include interference from other nearby radar systems. The interference can result in reduced sensitivity of the radar system. The techniques, apparatuses, and systems described herein mitigate the interference by identifying a set of samples of the radar radiation with interference. The interference can be estimated and mitigated by comparing this set (e.g., with interference) to a set of samples without interference and suppressing the interference without suppressing the detected signal. Further, the interference can be analyzed to determine if the interference contains detection information of one or more objects (e.g., other vehicles with radar systems causing interference). In this manner, interference mitigation may be obtained without losing information included in the set of samples including interference.
