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.
Claims17
A method of self-localization in a navigation environment in which a respective optical marker is attached at a plurality of positions, wherein a marker is detected and read by an optical code reader and its position is determined from the code content of the marker,
- wherein the markers are attached in groups of at least three respective markers;
- wherein a value range of the code content of the markers is smaller than the number of positions having an optical marker;
- and
- wherein the code content of the at least three markers of a group together uniquely describe the position of the group.
A self-localizing vehicle in a navigation environment in which a respective optical marker is attached to a plurality of positions, wherein the vehicle has an optical code reader for detecting the markers and a control and evaluation unit that is configured to determine the position of a detected marker by means of the code content thereof and thus to carry out a self-localization of the vehicle,
- wherein the markers are attached in groups of at least three respective markers;
- wherein a value range of the code content of the markers is smaller than the number of positions having an optical marker;
- and
- wherein the code content of the at least three markers of a group together uniquely describe the position of the group.
