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: The present disclosure provides a data processing system, method, and device. A method for monitoring a high definition map data collection trip includes recording data collected from one or more sensors associated with a vehicle, determining a current vehicle location, and determining whether the vehicle is following a planned route based on the current vehicle location. On a condition that the vehicle is not following the planned route, the method includes including an indication in the recorded data collected from the one or more sensors associated with the vehicle that the vehicle is off-route; generating additional navigation instructions, wherein the additional navigation instructions return the vehicle to the planned route; and providing the additional navigation instructions to a driver of the vehicle.

Abstract: The present disclosure provides a data processing system, method, and device for monitoring a high definition map data collection trip. A current vehicle location is determined. Whether the vehicle is following a planned route linked to a data collection trip, based on the current vehicle location is determined. On a condition that the vehicle is not following the planned route, a reason why the vehicle is not following the planned route is determined. An alert is generated, displayed on an in-vehicle navigation device, and uploaded with the reason to a command center.

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 localization for a non-transitory computer readable storage medium storing one or more programs is disclosed. The one or more programs comprise instructions, which when executed by a computing device, cause the computing device to perform by one or more autonomous vehicle driving modules execution of processing of images from a camera and data from a LiDAR using the following steps comprising: computing, in response to features from a 3D submap and features from a global map, matching score between corresponding features of a same class between the 3D submap and the global map; selecting, for each feature in the 3D submap, a corresponding feature with the highest matching score from the global map; determining a feature correspondence to be invalid if a distance between corresponding features is larger than a threshold; and removing the invalid feature correspondence.

Abstract: A method of localization for a non-transitory computer readable storage medium storing one or more programs is disclosed. The one or more programs comprise instructions, which when executed by a computing device, cause the computing device to perform by one or more autonomous vehicle driving modules execution of processing of images from a camera and data from a LiDAR using the following steps comprising: voxelizing a 3D submap and a global map into voxels; estimating distribution of 3D points within the voxels, using a probabilistic model; extracting features from the 3D submap and the global map; and classifying the extracted features into classes.
