  • Patent number: 12015877
    Abstract: A method is provided for the automatic configuration of a plurality of cameras that each have an image sensor, an illumination, and a communication interface and that are installed such that they together record objects in a detection zone by partially overlapping, mutually complementary fields of view, wherein the cameras are connected via their communication interfaces to form a network. In this process, the cameras produce sample recordings while only specific cameras activate their illumination, a check is made for the respective cameras with reference to the sample recordings whether there is a proximity relationship to a camera having active illumination, and the relative arrangement of the cameras with respect to one another is determined from the proximity relationships.
