Abstract: An occupancy grid probability prediction method includes: determining a dynamic particle probability based on a first probability that a dynamic particle will move from a donor cell of an occupancy grid to a recipient cell of the occupancy grid; and determining one or more predicted probabilities of at least one of the donor cell or the recipient cell based on the dynamic particle probability.

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: A method, for determining a dynamic occupancy grid, includes: obtaining radar measurement data from at least one radar sensor of an apparatus; obtaining camera-derived data based on at least one image obtained by at least one camera of the apparatus; and determining the dynamic occupancy grid based on the radar measurement data and the camera-derived data.

Abstract: An occupancy grid determination method includes: determining a predicted occupancy grid based on a previous occupancy grid, the predicted occupancy grid comprising a plurality of first cells corresponding to sub-regions of a region, each of the plurality of first cells including a plurality of predicted indications of probability each indicative of a predicted probability of a respective possible type of occupier of the respective first cell; determining, using machine learning and based on the first sensor measurements, an observed occupancy grid comprising a plurality of second cells corresponding to the sub-regions of the region; and determining an updated occupancy grid based on the observed occupancy grid and the predicted occupancy grid.

Abstract: Techniques are provided for detecting objects proximate to a vehicle with multiple signal paths. An example method for generating object representations with multiple signal paths includes obtaining image information from at least one camera module disposed on a vehicle, obtaining target information from at least one radar module disposed on the vehicle, generating a first detection representation with a first signal path based on the image information and the target information, generating a second detection representation with a second signal path based on the image information and the target information, wherein the second signal path is different than the first signal path, and outputting the first detection representation and the second detection representation.
