DEVICE FOR CALIBRATING A SPATIAL POSITION OF A CENTER OF AN ENTRANCE PUPIL OF A CAMERA, CALIBRATING METHOD THEREFOR AND SYSTEM FOR DETERMINING THE RELATIVE POSITION OF CENTERS OF ENTRANCE PUPILS OF AT LEAST TWO CAMERAS, WHICH ARE MOUNTED ON A COMMON SUPPORT FRAME, RELATIVE TO EACH OTHER AND DETERMINATION METHOD THEREFOR

摘要

The invention relates to a device (1) for calibrating a spatial position of a center of an entrance pupil of a camera (2). The device has a holder (4) for holding the camera (2) such that it covers a specified calibration field of view (5). At least two stationary reference cameras (7, 8) are used to capture the calibration field of view (5) from different directions. The device has at least one stationary main calibration area (15 to 17) arranged in the calibration field of view (5) and having stationary main calibration structures. The device furthermore has at least one additional calibration area (22 to 24) having additional calibration structures (25), which can be shifted in a driven manner between a neutral position and an operating position in the field of view (5). An analysis unit is used to process captured camera data of the camera (2) to be calibrated and of the reference cameras (7, 8) and state parameters of the device (1). The result is a device by means of which cameras can be precisely calibrated in respect of the spatial position of the center of the entrance pupils thereof.
