1. A system comprising:
a navigation marker designed to emit a fluorescence emission; and
a vehicle comprising:
a light detection assembly having:
a light emitting diode (LED) that emits ultraviolet (UV) light at a first wavelength;
a narrowband filter, wherein a second light emitted from the navigation marker and having a second wavelength can propagate through the narrowband filter and the narrowband filter blocks the first wavelength;
a photodiode aligned with the narrowband filter and configured to sense the second light propagating through the narrowband filter; and
a lens positioned between and aligned with the narrowband filter and the photodiode;
a computing device configured to:
determine optical data based on the second light sensed by the photodiode and 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, the vehicle action corresponding to one or more of reducing vehicle speed, increasing vehicle speed, stopping the vehicle, presenting an audible alarm, presenting a visual alarm, or wirelessly transmitting a message; and
cause the vehicle to perform the first vehicle action,
wherein the second light is emitted from the navigation marker illuminated by the first light.
