    摘要： Methods and systems for road flare detection are described. A computing device configured to control the vehicle, may be configured to receive, from an image-capture device, images; image portions of the images may depict an area within a predetermined distance from a surface of a road on which the vehicle is travelling. Also, the computing device may be configured to determine, based on characteristics of an object depicted in the image portions such as color spectrum of the object, brightness of the object, and whether the object is stationary or moving with respect to the road, a likelihood that the object represents a road flare. Based on the likelihood, the computing device may be configured to modify a control strategy associated with a driving behavior of the vehicle; and control the vehicle based on the modified control strategy.

    摘要： Methods and systems for alignment of light detection and ranging (LIDAR) data are described. In some examples, a computing device of a vehicle may be configured to compare a three-dimensional (3D) point cloud to a reference 3D point cloud to detect obstacles on a road. However, in examples, the 3D point cloud and the reference 3D point cloud may be misaligned. To align the 3D point cloud with the reference 3D point cloud, the computing device may be configured to determine a planar feature in the 3D point cloud of the road and a corresponding planar feature in the reference 3D point cloud. Further, the computing device may be configured to determine, based on comparison of the planar feature to the corresponding planar feature, a transform. The computing device may be configured to apply the transform to align the 3D point cloud with the reference 3D point cloud.

    摘要： Methods and systems for modifying vehicle behavior based on confidence in lane estimation are described. In an example, a computing device may be configured to receive lane information relating to locations of lane boundaries and may be configured to estimate a lane boundary on a road on which the vehicle is traveling, based on the lane information. The computing device also may be configured to determine a level of confidence for the estimated lane boundary, modify a driving behavior for the vehicle based on the level of confidence, and also may be configured to control the vehicle based on the modified driving behavior.

    摘要： Robotic systems for modeling, mapping and exploring subterranean void spaces such as mines, caves, tunnels, bunkers, and conduits. Robotic modeling of subterranean voids is generally enabled by a procedural system consisting of preprocessing, ingress, void modeling, mapping and navigation, exploration, conveying payloads other than void modeling sensors, egress, and post processing. The robots can either be imposed mobility or can be self mobile with either autonomous, remote, teleoperated, or manual modes of operation. The robot may optionally transform from a compact size into a more conventional operating size if the operating size exceeds the void entry opening size. Void geometries with flat floors are amenable to robot locomotion such as rolling, crawling, walking or swimming. Alternatively, irregular floor geometries that preclude self mobilization may be accessible by imposed mobilization such as dropping or pushing a movable robotic sensor into such voids. The robotic device is preferably adaptable to voids filled with a gas or liquid. To maximize mapping applicability, the robot optionally includes sensing, locomotion and environmental tolerance to submersion and safeguarding, according to use criteria.
