Abstract: The invention relates to a method of increasing accuracy of a global position of a user receiver determined by a navigation system. The global position is corrected based on a position error determined by a mobile reference receiver and transmitted to the user receiver. The invention further relates to a corresponding apparatus.

Abstract: In a method of recognizing and/or tracking objects which correspond to real objects in at least one sensing zone of at least one sensor for electromagnetic radiation on the basis of images of the sensing zone repeatedly sensed by means of the sensor, succeeding images are evaluated in succeeding cycles and a search is made for at least one respective object found in a cycle on the basis of a corresponding image in a correspondingly later image in a later cycle to track the object. At least one part of an earlier image and/or at least one indication with respect to an earlier state of the object or of a real object corresponding to it, which is determined using a corresponding earlier image in the current cycle, is associated with at least one part of a current image determined in the current cycle or with an object recognized in the current cycle during at least one current cycle on the basis of the results of an at least preliminary evaluation of a current image.

The raw data elements corresponding to said amounts respectively comprise at least the coordinates of object points detected by the associated sensor in relation to the position of the detecting sensor.

Abstract: The invention relates to a method for optically sensing the surrounding area of a vehicle using at least one optoelectronic emitting/receiving device that is mounted on the vehicle. According to the method, a monitoring area located in the field of vision of the emitting/receiving device is scanned and, in addition to the monitoring area, a region of particular interest is scanned by using at least one radiation deflecting device, which is located in the field of vision of the emitting/receiving device, however, outside of the monitoring area. The invention also relates to a corresponding sensing device.

Distances between the distance image sensor and regions on at least one calibration surface are found by means of the distance image sensor and a value for a parameter which at least partly describes the alignment is determined using the distances that are found.
