Abstract: In various examples, object fence corresponding to objects detected by an ego-vehicle may be used to determine overlap of the object fences with lanes on a driving surface. A lane mask may be generated corresponding to the lanes on the driving surface, and the object fences may be compared to the lanes of the lane mask to determine the overlap. Where an object fence is located in more than one lane, a boundary scoring approach may be used to determine a ratio of overlap of the boundary fence, and thus the object, with each of the lanes. The overlap with one or more lanes for each object may be used to determine lane assignments for the objects, and the lane assignments may be used by the ego-vehicle to determine a path or trajectory along the driving surface.

Abstract: Among multiple different area classes designated regarding photographic subjects, to which area class a photographic subject of each pixel in a captured image that has been acquired belongs is recognized. From depth map information corresponding to the captured image, range information of each pixel in an area in the captured image representing a vehicle area class among the multiple different area classes is acquired, and a position at which the range information is discontinuous is determined to be a boundary between different vehicles.

Abstract: A vehicular vision system includes a sensor disposed at a vehicle and having a field of sensing exterior of the vehicle. The sensor captures sensor data. Electronic circuitry of an electronic control unit (ECU) includes a processor for processing sensor data captured by the sensor. Responsive to the vehicle being parked, captured sensor data is processed at the ECU to determine a topography of the environment at the parked vehicle. The ECU, responsive to determining the topography at the parked vehicle determines presence of a hazard of the topography. The ECU, responsive to determining presence of the hazard, notifies an occupant of the vehicle of the hazard prior to the occupant exiting the parked vehicle.

Abstract: The positional precision assessment device has a processor configured to estimate a first location of a moving object at a first time based on an image representing road features and positional information, estimate a second location at the first time based on a location of the moving object at the second time and an amount of movement and change in direction from the second time to the first time, input the first and second location into a filter and calculate a current location at the first time, and determine a state of precision of the current location based on a difference between the current location of the moving object and a location estimated based on a location of the moving object at a time prior to the first time and an amount of movement and change in direction from the prior time to the first time.

Abstract: A method and system for estimating road lane geometry includes a camera-estimated lane segment, for estimating lane geometry based on camera detection of road markings and a leading-vehicle-estimated lane segment, for estimating lane geometry based on traces of at least one leading vehicle. Estimated road geometry is obtained from a combination of the camera-estimated lane segment and the leading-vehicle-estimated lane segment.

Abstract: A method and system for determining a geographical location and orientation of a vehicle travelling through a road network is disclosed. The method comprises obtaining, from one or more cameras associated with the vehicle travelling through the road network, a sequence of images reflecting the environment of the road network on which the vehicle is travelling, wherein each of the images has an associated camera location at which the image was recorded. A local map representation representing an area of the road network on which the vehicle is travelling is then generated using at least some of the obtained images and the associated camera locations. The generated local map representation is compared with a section of a reference map, the reference map section covering the area of the road network on which the vehicle is travelling, and the geographical location and orientation of the vehicle within the road network is determined based on the comparison. Methods and systems for generating and/or updating an electronic map using data obtained by a vehicle travelling through a road network represented by the map are also disclosed.
