Abstract:
A vehicle is provided that may distinguish between dynamic obstacles and static obstacles. Given a detector for a class of static obstacles or objects, the vehicle may receive sensor data indicative of an environment of the vehicle. When a possible object is detected in a single frame, a location of the object and a time of observation of the object may be compared to previous observations. Based on the object being observed a threshold number of times, in substantially the same location, and within some window of time, the vehicle may accurately detect the presence of the object and reduce any false detections.
Abstract:
Methods and systems for road boundary and lane tracing are described herein. In an example implementation, a computing system of a vehicle may receive boundary data associated with a road and may determine edge data representative of edges of the boundaries. A given edge may indicate a discontinuity between a boundary and a characteristic of the road. The computing system may modify the edge data based on a position and orientation of respective edges to combine edges positioned substantially in parallel and within a threshold distance to each other. The computing system may adjust boundary data based on the modified edge data so as to extend a given boundary that includes a combined edge and may determine whether extended boundary data substantially matches road data indicated by a map. In addition, the computing system may provide an estimation of projections of boundaries ahead of the vehicle on the road.
Abstract:
Methods and systems for construction zone object detection are described. A computing device may be configured to receive, from a LIDAR, a 3D point cloud of a road on which a vehicle is travelling. The 3D point cloud may comprise points corresponding to light reflected from objects on the road. Also, the computing device may be configured to determine sets of points in the 3D point cloud representing an area within a threshold distance from a surface of the road. Further, the computing device may be configured to identify construction zone objects in the sets of points. Further, the computing device may be configured to determine a likelihood of existence of a construction zone, based on the identification. Based on the likelihood, the computing device may be configured to modify a control strategy of the vehicle; and control the vehicle based on the modified control strategy.
Abstract:
Methods and systems for lane boundary detection using images are described. A computing device may be configured to receive, from an image-capture device coupled to a vehicle, an image of a road of travel of the vehicle. The computing device may be configured to identify a pixel in the image based on an intensity of the pixel and a comparison of the intensity of the pixel to respective intensities of neighboring pixels. Based on the intensity of the pixel and the comparison, the computing device may be configured to determine a likelihood that the pixel belongs to a portion of the image depicting a lane marker on the road. Based at least on the likelihood, the computing device may be configured to and provide instructions to control the vehicle.
