    Abstract: A dynamic occupancy grid determination method includes: obtaining, at an apparatus, at least one radar-based occupancy grid based on radar sensor measurements, each of the at least one radar-based occupancy grid comprising a plurality of first cells, each cell of the plurality of first cells having a corresponding first occupancy probability and first velocity; obtaining, at the apparatus, at least one camera-based occupancy grid based on camera measurements, each of the at least one camera-based occupancy grid comprising a plurality of second cells, each cell of the plurality of second cells having a corresponding second occupancy probability and second velocity; and determining, at the apparatus, a dynamic occupancy grid by analyzing the at least one radar-based occupancy grid and the at least one camera-based occupancy grid.

    Abstract: In some aspects, a device may obtain sensor data associated with identifying measured properties of an object in an environment. The device may detect a trigger event associated with at least one of the environment or the device. The device may modify, based on detecting the trigger event, one or more pre-processing operations associated with the sensor data for input to a neural network, and/or one or more post-processing operations associated with an object detection output of the neural network. The device may perform the one or more pre-processing operations associated with the sensor data to generate pre-processed sensor data. The device may generate the object detection output for the object based on detecting the object using the pre-processed sensor data as the input to the neural network. The device may perform the one or more post-processing operations using the object detection output. Numerous other aspects are described.

    Abstract: A range estimator determines an at least one code sequence, causes an at least one light source to send the at least one code sequence as an at least one coded light transmission toward one or more targets, wherein the at least one code sequence is encoded as an amplitude-based code over time, or as a wavelength-based code over time, or as a combination thereof, in the at least one coded light transmission, causes a reflected version of the at least one coded light transmission to be received at an at least one sensor from the one or more targets, as a reflected light signal, correlates the reflected light signal with the at least one code sequence, to generate a time-of-flight value for the at least one coded light transmission, and generates a range estimate for the at least one coded light transmission based on the time-of-flight value.

    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: Methods, systems, computer-readable media, and apparatuses for determining one or more attributes of at least one target based on eigenspace analysis of radar signals are presented. In some embodiments, a subset of eigenvectors to use for forming a signal or noise subspace is identified based on principal component analysis. In some embodiments, the subset of eigenvectors is identified based on estimating the total number of targets using a discrete Fourier transform (DFT) or other spectral analysis technique. In some embodiments, a DFT is used to identify areas of interest in which to perform eigenspace analysis. In some embodiments, a DFT is used to estimate one attribute of a target, and eigenspace analysis is performed to estimate a different attribute of the target, with the results being combined to generate a multi-dimensional representation of a field of view.
