Abstract: A method of safeguarding a machine is provided in which a sensor monitors the machine and generates data thereon that are evaluated so that a hazardous situation is recognized and the machine is safeguarded in the event of a hazardous situation, wherein a check is made in a detection capability check whether an estimation of a hazardous situation is possible and the machine is otherwise safeguarded. In this respect, the sensor data are evaluated in a process of machine learning having at least one figure of quality in the detection capability check and an estimation of a hazardous situation is only considered possible with a sufficient figure of quality.

Abstract: A method of safeguarding at least one machine (12) that is monitored by at least one sensor (14) that generates sensor data with respect to the machine (12) is provided, wherein movements of a machine model of the machine (12) are carried out in a simulation and synthetic sensor data of a sensor model of the sensor (14) are generated, and wherein a plurality of safety functions (72) are performed in the simulation in which an evaluation is made by safety related evaluation of the simulation whether a hazardous situation is present to output a safety signal to the machine (12) to trigger a safety response in the case of a hazardous situation, The safety functions (72) are here each individually implemented per se in a container.

Abstract: A method of self-localization in a navigation environment is provided in which a respective optical marker is attached to a plurality of positions, wherein a marker is detected and read by an optical code reader and the position of the marker is determined from the code content. In this respect, the markers are attached in groups of at least three respective markers; a value range of the code content of the markers is smaller than the number of positions having an optical marker; and the code content of the at least three markers of a group together uniquely describe the position of the group.

Abstract: A camera device for localizing an optical marker is provided that has at least one image sensor and a control and evaluation unit. A first camera channel for recording first image data having the optical marker is formed from the image sensor and the control and evaluation unit. The control and evaluation unit is configured to locate the optical marker in the first image data and to determine a first pose of the optical marker relative to the camera device. A second camera channel for recording second image data having the optical marker is formed from the image sensor and the control and evaluation unit. The control and evaluation unit is configured to locate the optical marker in the second image data, to determine a second pose of the optical marker relative to the camera device, and to compare the first pose and the second pose with one another.
