Abstract
The invention relates to a method for providing corrected data in order to generate a model of a monitoring area which is located in the respective visual range of at least two opto-electronic sensors for determining the position of detected objects, based on the amounts of raw data elements corresponding to object points in said monitoring area, said amounts of raw data elements being respectively detected by one of the sensors when the visual range is sensed and associated therewith, and the amounts of raw data elements from various sensors which are temporally linked to each other forming a group. 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. In order to form corrected amounts of corrected data elements corresponding to the amounts of raw data elements of a group for each group quantity, the coordinates contained in the raw data elements are transformed into a common coordinate system, taking into account the relative position of the respective sensors.

21. A method for the provision of corrected data for the production of a model of a monitored zone (26), which lies in respective fields of view (22, 24) of at least two optoelectronic sensors (10, 12), in particular laser scanners, for the determination of the position of detected objects (28) and contains object points, the corrected data being provided on the basis of sets of raw data elements corresponding to object points in the monitored zone,
wherein the sets of raw data elements are respectively detected by one of the sensors (10, 12) by scanning its field of view (22, 24) and are associated with it; -
wherein the sets of raw data elements of different sensors (10, 12) with a specific time association relative to one another form a group; and
wherein the raw data elements of the sets include at least the coordinates of object points detected by the associated sensor (10, 12) in each case with respect to the position of the detecting sensor (10, 12), wherein, for the formation of corrected sets of corrected data elements corresponding to the sets of raw data elements of the group, the coordinates contained in the raw data elements are transformed for each set of the group into a common coordinate system, while taking account of the relative position of the respective sensors (10, 12). - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
