    摘要: A method and a system for precision vehicle positioning based on a digital road description database containing fourth data sets with object-based information about at least one of a road object, a road furniture object and a geographic object is disclosed. First data sets based on the fourth data sets are forwarded to a vehicle. The vehicle is collecting ambient data like images along its path, generating second data sets comprising at least location information and detailed object-based information. During driving and after generating second data sets, the vehicle tries to identify in the second data sets the same driving-relevant objects and/or object reference points and/or groups of driving-relevant objects and/or object reference points as are contained in the first data sets. Furthermore, the vehicle aligns the same driving-relevant objects and/or object reference points and/or groups of driving-relevant objects and/or object reference points between the second data sets and the first data sets, and derives a position value for its own position.

    摘要: It is an object to enable a state concerning a present location to be estimated with high precision by a Kalman filter. A navigation system 1 includes a GPS reception unit 5 that receives a GPS signal, an observation unit 21 that observes observables including a GPS vehicle position based on the received GPS signal, and an estimation unit 22 that estimates state quantities concerning the present location based on the observables observed by the observation unit 21 and on the Kalman filter, and the estimation unit 22 calculates prediction values of the state quantities and errors of the prediction values, calculates estimation values of the state quantities and errors of the estimation values, based on the prediction values, the errors of the prediction values and errors of the observables observed by the observation unit 21, and, when calculating the estimation values and the errors of the estimation values, assigns a weight based on a period from a first timing to a second timing in which the GPS signal received in the first timing is not reflected in observation of the GPS vehicle position by the observation unit 21, to an error of the GPS vehicle position.

    摘要: The invention relates to a surveying subsystem comprising a camera module, a profiler and a control and evaluation unit, the surveying subsystem being adapted to be used as part of a surveying system that is adapted to determine positions of a position measuring resource, particularly a GNSS-antenna or a retro-reflector mounted - together with the surveying subsystem - on a surveying pole.
    The images taken by the camera - when moving along a path through a surrounding - are used within a SLAM process so as to derive a 6-dof-travelling-history for the surveying subsystem including translational and rotational information in 6 degrees of freedom for the moved path based on the SLAM-evaluation.
    According to the invention, the control and evaluation unit has stored a program with program code for controlling and executing a spatial representation generation functionality in which coordinates for points of the surrounding are determined as the spatial representation based on the profiler measurement data in combination with the derived 6-dof-travelling-history.

    摘要: The invention discloses an improved GNSS receiver which determines a location of the receiver by combining a first location determined from the standard PVT and a second location determined by integrating the velocity from the standard PVT. The combination is based on a weighting of the error budgets of the first position and the second location. The improved receiver is preferably based on a standard receiver with an add-on software module which receives and processes data transmitted from the standard receiver by, for example, NMEA messages. The improved receiver allows a determination of a more precise and smoother trajectory in a simple way.
