Abstract: The present disclosure provides methods and systems of maintaining a map suitable for guiding autonomous driving. In some embodiments, the method may include receiving a sensor dataset acquired by a sensor subsystem, wherein: the sensor dataset includes information about a road, the sensor subsystem comprises multiple different types of sensors; determining, by a processor, a confidence level by comparing the sensor dataset and the map that includes prior information about the road; in response to determining that the confidence level exceeds a confidence threshold, processing the map by the processor; and storing the processed map as an electronic file, wherein the processed map is configured to guide an autonomous vehicle to operate on the road.

Abstract: Disclosed are devices, systems and methods for capturing an image. In one aspect an electronic camera apparatus includes an image sensor with a plurality of pixel regions. The apparatus further includes an exposure controller. The exposure controller determines, for each of the plurality of pixel regions, a corresponding exposure duration and a corresponding exposure start time. Each pixel region begins to integrate incident light starting at the corresponding exposure start time and continues to integrate light for the corresponding exposure duration. In some example embodiments, at least two of the corresponding exposure durations or at least two of the corresponding exposure start times are different in the image.

Abstract: A system and method for image localization based on semantic segmentation are disclosed. A particular embodiment includes: receiving image data from an image generating device mounted on an autonomous vehicle; performing semantic segmentation or other object detection on the received image data to identify and label objects in the image data and produce semantic label image data; identifying extraneous objects in the semantic label image data; removing the extraneous objects from the semantic label image data; comparing the semantic label image data to a baseline semantic label map; and determining a vehicle location of the autonomous vehicle based on information in a matching baseline semantic label map.

Abstract: Techniques are described for estimating pose of a camera located on a vehicle. An exemplary method of estimating camera pose includes obtaining, from a camera located on a vehicle, an image including a lane marker on a road on which the vehicle is driven, and estimating a pose of the camera such that the pose of the camera provides a best match according to a criterion between a first position of the lane marker determined from the image and a second position of the lane marker determined from a stored map of the road.

Abstract: A method of sharing information about an object or a condition on a road includes receiving, by a server from a first autonomous vehicle, a message comprising a first data structure that includes information about a driving condition on a road; and transmitting, by the server to a second autonomous vehicle, a second data structure that includes information about the driving condition on the road, where the second data structure is transmitted in response to determining that a location of the driving condition is related to a trajectory on which the second autonomous vehicle is operating or is expected to drive, where the second data structure is transmitted to the second autonomous vehicle before the second autonomous vehicle reaches the location of the driving condition, and where the server is located in a fixed location outside of the first autonomous vehicle and the second autonomous vehicle.
