Systems and methods for controlling vehicles with navigation markers

A vehicle comprising:

• a light detection assembly having:
• a light emitter configured to emit a first light at a first wavelength;
• an optical filter, wherein a second light is emitted from a navigation marker illuminated by the first light and corresponding to a second wavelength can propagate through the optical filter and the optical filter blocks the first wavelength;
• and
• an optical sensor aligned with the optical filter and configured to sense the second light propagating through the optical filter;
• a computing device configured to:
• determine optical data based on the second light sensed by the optical sensor, the optical data indicative of the second wavelength;
• determine the optical data corresponds to a first vehicle action based on the second wavelength and a database, the database comprising a first vehicle action and a second vehicle action and associating the first vehicle action with the second wavelength and the second vehicle action with a third wavelength;
• and
• cause the vehicle to perform the first vehicle action based on the optical data corresponding to the first vehicle action.

A method comprising:

• causing a light emitter to emit a first light having a first wavelength;
• determining an electrical signal based on a second light filtered through an optical filter, the second light having a second wavelength and emitted from a navigation marker designed to emit a fluorescence emission, and the optical filter designed to permit the second light through the optical filter and block the first light;
• determining optical data having a first intensity value of the second light;
• determining the first intensity value satisfies a threshold value indicative of the second wavelength
• determining the optical data corresponds to a first action based on the second wavelength and a database, the database comprising a first action and a second action and associating the first action with the second wavelength and the second action with a third wavelength;
• and
• causing a vehicle to perform the first action,
• wherein the second light is emitted from the navigation marker illuminated by the first light.
