Abstract: The invention relates to a monitoring device 1 for monitoring a man-overboard situation in a ship section 4, wherein the ship section 4 is monitored by video technology using at least one camera 5a,5b and the camera 5a,5b is designed to provide surveillance in the form of video data. The monitoring device comprises an evaluation device 7, said evaluation device 7 having an interface for receiving the video data, wherein the evaluation device 7 is designed to detect a moving object in the ship section 4 on the basis of the video data and to determine a kinematic variable of the moving object. The evaluation device 7 is designed to determine a starting point in three dimensions on the basis of the video data and the kinematic variable of the moving object and to evaluate the moving object as a man-overboard event on the basis of the starting point.

Abstract: The invention relates to a calibration unit (2) for a monitoring device (1), wherein the monitoring device (1) is designed as man-overboard monitoring of a ship section (4), wherein the monitoring device has at least one camera (5a, 5b) for video-monitoring the ship section (4) and for providing video data, wherein the camera (5a, 5b) has at least one intrinsic calibration parameter (11) and at least one extrinsic calibration parameter (12), wherein the video data is provided to the calibration unit (2), comprising an input module (9) for a user to input one or more calibration elements (10) and comprising an evaluation module (8), wherein the evaluation module (8) is designed to determine the unknown calibration parameters (11, 12) based on the calibration elements (10), in particular their orientation and/or extension.
