Abstract: A sensor system for monitoring a spatial region in an outdoor region or in an industrial plant, for example for use on a manned vehicle or an autonomously driving industrial truck, includes a sensor arrangement. The sensor system is configured to generate 2D and 3D data of the spatial region. In this respect, the sensor system has a computing device that is configured to perform a person detection method on the 2D data of the spatial region in order to recognize persons in the spatial region. 2D position data are determined for a recognized person. The computing device is furthermore configured, on the basis of the 2D position data for the recognized person, to assign 3D data associated with the recognized person. The computing device is further configured to determine 3D position data for the recognized person from the 3D data associated with the recognized person.

Abstract: In a method for creating a 3D representation of a recording object it is provided, with respect to recorded individual images (2, 3) from a recording object, to identify feature pixels (6, 7, 8, 9) respectively in a computer-aided manner by a feature detection, to calculate in a computer-implemented manner with respect to this feature pixels (6, 7, 8, 9), on the basis of correspondences in terms of content, respectively 3D points (11, 12) and camera poses (3, 4) of the individual images (2, 3), to fit at least one geometric primitive (14) into the calculated 3D points (11, 12) in a computer-implemented manner and to check in a plausibility check (15) whether a minimum discrepancy between the individual images (2, 3) results for the geometric primitive (14), and to output the geometric primitive (14) for which the discrepancy is minimized.
