摘要

The device (1) has infrared cameras (3a, 3b) arranged at a defined distance to each other and provided with a calibration device (19) for sequential automatic calibration of the cameras, where the calibration device exhibits a radiation source (21) and a reference beam input (20). A collimated radiation beam (22) output from the radiation source is divided into two partial radiation beams (22a, 22b). The partial beams are deflected on the cameras over an optical deflection element e.g. penta-prism (23a), attached to the cameras. An optical separating element is designed as a 90-degree-prism. Independent claims are also included for the following: (1) a monitoring device comprising a stereocamera device (2) a method for sequential automatic calibration of a stereocamera device (3) a computer program comprising a set of instructions to perform a method for the sequential automatic calibration of the stereocamera device (4) a computer program product comprising the set of instructions to perform a method for the sequential automatic calibration of the stereocamera device.
