Abstract
Disclosed is a navigation method and system using color codes. The navigation method according to an embodiment of the present disclosure includes: dividing an aircraft path at a vertiport into a plurality of sub-paths based on a branch point; and selectively combining at least some of the plurality of sub-paths and generating a guiding path for an urban air mobility (UAM) to travel at the vertiport based on a departure point and a destination point scheduled for the UAM.
Claims11
A navigation method using color codes that allows an urban air mobility (UAM) to automatically traverse a guiding path through an aircraft path having a branch point, the navigation method comprising:
- dividing the aircraft path at a vertiport into a plurality of sub-paths, based on the branch point, so that differing ones of the plurality of sub-paths at the branch point having differing assigned colors;
- automatedly selectively combining at least some of the plurality of sub-paths to generate the guiding path for the UAM to travel at the vertiport, based on a departure point and a destination point scheduled for the UAM, wherein the guiding path traverses the branch point and is composed of a plurality of colored segments;
- and
- automatedly navigating the UAM along the aircraft path based on the guiding path, wherein the automatedly navigating includes:
- sensing, as the UAM traverses at least a portion of the aircraft path and using a vision camera having a color sensor, color codes on markers along the aircraft path;
- matching the sensed color codes on the markers to the colored segments of the guiding path so as to differentiate between differing ones of the plurality of sub-paths branching from the branch point;
- and
- controlling movement of the UAM along the aircraft path based on the matching of the sensed color codes to the colored segments.
A navigation system using color codes that allows an urban air mobility (UAM) to automatically traverse a guiding path through an aircraft path having a branch point, the navigation system comprising:
- a divider configured to divide the aircraft path at a vertiport into a plurality of sub-paths based on the branch point, so that differing ones of the plurality of sub-paths at the branching point have differing assigned colors;
- and
- a processor configured to automatedly selectively combine at least some of the plurality of sub-paths to generate the guiding path for the UAM to travel at the vertiport, based on a departure point and a destination point scheduled for the UAM, wherein the guiding path traverses the branch point and is composed of a plurality of colored segments;
- and
- a navigation controller configured to automatedly navigate the UAM along the aircraft path based on the guiding path, wherein the automatic navigation includes:
- sensing, as the UAM traverses at least a portion of the aircraft path and using a vision camera having a color sensor, color codes on markers along the aircraft path;
- matching the sensed color codes on the markers to the colored segments of the guiding path so as to differentiate between differing ones of the plurality of sub-paths branching from the branch point;
- and
- controlling movement of the UAM along the aircraft path based on the matching of the sensed color codes to the colored segments.
