1. A method for capturing optical image data of patient surroundings and for identifying a patient check-up based on the image data, the method comprising the steps of:
receiving captured optical image data of patient surroundings;
detecting a patient based on the optical image data;
detecting at least one additional person based on the optical image data;
determining at least one geometric relation between the patient and the at least one additional person based on the optical image data, wherein determining the geometric relation comprises determining a body orientation of the at least one additional person in relation to the patient, and/or determining a viewing direction by an orientation of the head or eyes of the at least one additional person in relation to the patient based on the optical image data; and
identifying the patient check-up based on the geometric relation and on a time period during which the geometric relation between the patient and the at least one additional person was present.
