HITCH-ANGLE ESTIMATION FOR TRACTOR-TRAILER COMBINATION
Disclosed is an arrangement and a method for hitch-angle estimation for a tractor-trailer combination. The arrangement comprising one or more sensors for providing one or more point clouds comprising a representation for the trailer as seen from one or more measurement positions at the tractor, a first measurement for the speed of the tractor, and a second measurement for an orientation of the tractor. The arrangement also comprises a computing unit configured to obtain one or more first values indicating the hitch angle between the tractor and the trailer, determined from the one or more point clouds, obtain a second value indicating the rate of change for the hitch angle, determined from the first and the second measurement, and fuse the one or more first values and the second value to provide an estimate for the hitch angle between the tractor and the trailer.
NAVIGATION SYSTEM AND METHOD FOR ERROR CORRECTION
The invention regards a navigation system and a method for error correction. The navigation system comprises a base navigation system and a correction system. Measurement uncertainties are assigned to each measurement and an error threshold is computed on the basis of these uncertainties. Redundant measurements are determined and residuals for at least a pair of redundant measurements as a discrepancy measure are calculated. In case that the residual exceeds a respective threshold an error count for each measurement involved in the determination of the residual is increased. All residuals for each measurement are summed up for a particular measurement and for carrying out the correction in a fusion filter measurements are selected on the basis of their respective error count and summed up residuals.
IMAGE ORIENTATION CONTROL FOR A PORTABLE DIGITAL VIDEO CAMERA
An integrated hands-free, point of view, action-sports, digital video camera (or camcorder) (10) includes: a rotary horizon adjustment controller (14) for adjusting the orientation of a horizontal image plane (16) recorded by an image sensor with respect to the orientation of a camera housing (22); a laser alignment system with laser sources (48) capable of projecting light to define a horizontal projection axis (52) that is coordinated with orientation of the horizontal image plane (16); a manually operable switch (80), which covers a microphone (90) whenever the switch (80) is in the OFF position, for controlling video data capture; and a “quick-release” mounting system (120) that retains a desired orientation of the camera (10).

3D Scene Scanner and Position and Orientation System
A hand-held mobile 3D scanner (10) for scanning a scene. The scanner (10) comprises a range sensor (11) that is arranged to sense the location of surface points in the scene relative to the scanner (10) and generate representative location information, a texture sensor (12) that is arranged to sense the texture of each surface point in the scan of the scene and generate representative texture information, and a position and orientation sensor (13) that is arranged to sense the position and orientation of the scanner (10) during the scan of the scene and generate representative position and orientation information. A control system (14) is also provided that is arranged to receive the information from each of the sensors and generate data representing the scan of the scene.
Position and orientation calibration method and apparatus
A position and orientation measuring apparatus calculates a difference between an image feature of a two-dimensional image of an object and a projected image of a three-dimensional model in a stored position and orientation of the object projected on the two-dimensional image. The position and orientation measuring apparatus further calculates a difference between three-dimensional coordinate information and a three-dimensional model in the stored position and orientation of the object. The position and orientation measuring apparatus then converts a dimension of the first difference and/or the second difference to cause the first difference and the second difference to have an equivalent dimension and corrects the stored position and orientation.
DECENTRALIZED TRAJECTORY PLANNING FOR MULTI-AGENT COORDINATION
Techniques are disclosed for a decentralized path and motion planning of autonomous agents within an environment. The planning may include determining if an active neighboring autonomous agent is present and selectively controlling the autonomous agent to operation in in an independent path planning operation mode and in a coordinating path planning operation mode, based on the detection of the neighboring agent(s).
A REAL-TIME MAP GENERATION SYSTEM FOR AUTONOMOUS VEHICLES
In one embodiment, a system receives a stream of frames of point clouds from one or more LIDAR sensors of an ADV and corresponding poses in real-time. The system extracts segment information for each frame of the stream based on geometric or spatial attributes of points in the frame, where the segment information includes one or more segments of at least a first frame corresponding to a first pose. The system registers the stream of frames based on the segment information. The system generates a first point cloud map for the stream of frames based on the frame registration.
