Methods and Systems for Map Matching
An advanced map matching algorithm is disclosed, which embeds the road topology inherently in a set of path candidates. Road connectivity is maintained even in special situations such as U-turns, reverse driving, and tunnels. Careful path candidate management is designed to reduce the candidate count while preserving well-matching candidates. Paths are treated and evaluated independently using multiple criteria, which makes the algorithm reliable and robust in different scenarios.
Updating road maps
A technique for updating road maps is disclosed. A number of GPS traces can be matched with a number of roads in a map. Matched GPS traces may be processed by a matched segment module to produce proposed changes to the map. The map can be updated using a map updating module based on the proposed changes from the matched segment module. Unmatched GPS traces may be processed by an unmatched segment module to produce proposed changes to the map. The map can be updated using a map updating module based on the proposed changes from the unmatched segment module. The proposed changes to the map may include metadata defining new roads in the map, new intersections in the map, updates to turn restrictions in the map, updates to the allowable directional traffic flow on the roads within the map, updates to road closures in the map.
THREE-DIMENSIONAL INFORMATION PROCESSING METHOD AND THREE-DIMENSIONAL INFORMATION PROCESSING DEVICE
A three-dimensional information processing method includes: obtaining, via a communication channel, map data that includes first three-dimensional position information; generating second three-dimensional position information from information detected by a sensor; judging whether one of the first three-dimensional position information and the second three-dimensional position information is abnormal by performing, on one of the first three-dimensional position information and the second three-dimensional position information, a process of judging whether an abnormality is present; determining a coping operation to cope with the abnormality when one of the first three-dimensional position information and the second three-dimensional position information is judged to be abnormal; and executing a control that is required to perform the coping operation.
AUGMENTED 3D MAP
The present technology provides systems, methods, and devices that can dynamically augment aspects of a map as an autonomous vehicle navigates a route, and therefore avoids the need for dispatching a special purpose mapping vehicle to keep navigating a route. As the autonomous vehicle navigates a route, the autonomous vehicle can determine that current data captured by at least one sensor of the autonomous vehicle describing a location is inconsistent with the primary map of the location. The autonomous vehicle can determine that a portion of the current data describes a second feature that is distinct from a first feature described by a primary map. The second feature can be added to an augmented map that is based on the primary map, and the position of the autonomous vehicle can be located with respect to the first feature rather than the second feature on the augmented map.
METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR SURVEILLANCE OF ROAD ENVIRONMENTS VIA DEEP LEARNING
A method, apparatus and computer program product are provided for surveillance of road environments via deep learning. In this regard, one or more features for vehicle sensor data associated with one or more vehicles traveling along a road segment proximate to a vehicle are determined. The vehicle includes one or more sensors that captures the vehicle sensor data. Furthermore, vehicle behavior data associated with the one or more vehicles is predicted using a machine learning model that receives the one or more features. The machine learning model is trained for detection of vehicle behavior based on historical vehicle sensor data and one or more rules associated with the road segment. The vehicle behavior data is also encoded in a database to facilitate modeling of vehicle behavior associated with the road segment.
METHOD FOR PREDICTING FUTURE DRIVING CONDITIONS FOR A VEHICLE
In a method for predicting future driving conditions for a vehicle (1), sensor data (2) are gathered while the vehicle (1) is traveling on a route. A position of the vehicle (1) is also determined. The gathered data are associated with the determined vehicle position. A map (9) is created depending on the associated data. When the route is traveled again, the map is updated in real time depending on associated data from the repeated traveling. Finally, a prediction of future driving conditions is obtained based on the determined vehicle position and the map (9).
A METHOD FOR DETERMINING A DRIVABLE AREA BY A VEHICLE
A method for determining a drivable area by a vehicle. The method comprising; obtaining data related to a track of the vehicle, wherein the data comprises a plurality of corresponding positions, headings and articulation angles of the vehicle along the track, obtaining size information of the vehicle, determining a swept area of the vehicle for the track based on the data and on the size information of the vehicle, configuring a sensor on the vehicle to detect when the vehicle drives over an obstacle, recording any obstacles detected by the sensor, and determining the drivable area based on the swept area and on recorded obstacles.
POSITIONING METHOD AND ELECTRONIC DEVICE
A positioning method and an electronic device are provided. The method comprises: acquiring azimuth angle data collected by a first sensor and acceleration data collected by a second sensor respectively (101); judging whether a turning event occurs at a current moment based on the azimuth angle data and the acceleration data (102); and if a turning event occurs, generating a positioning request to acquire position data of the current moment based on the positioning request for positioning and displaying (103). In the method, the positional change caused by a turning action is identified and positioned, so that a motion trajectory displayed in a map reflects the actual movement more truly.

Systems and methods are provided for navigating a host vehicle. In an embodiment, a processing device may be configured to receive a plurality of images captured by an image capture device, the plurality of images being representative of an environment of the host vehicle; analyze at least one of the plurality of images to identify a target vehicle in the environment of the host vehicle; receive map information associated with an environment of the host vehicle; determine a trajectory of the target vehicle over a time period based on analysis of the plurality of images; determine, based on the determined trajectory of the target vehicle and the map information, a position of the target vehicle relative to a road in the environment of the host vehicle; and determine a navigational action for the host vehicle based on the determined position of the target vehicle.
