Dual spinning laser-based UAV positioning and landing system and method

A dual spinning laser-based unmanned aerial vehicle (UAV) positioning and landing system, comprising:

• a first laser module, configured to provide a first light beam emitted by rotating around a first axis;
• a first rotating module, connected with the first laser module, and configured to drive the first laser module to rotate around a rotation axis perpendicular to the first axis to allow the first light beam to scan in a space;
• a second laser module, configured to provide a second light beam emitted by rotating around a second axis;
• a second rotating module, connected with the second laser module, and configured to drive the second laser module to rotate around a rotation axis perpendicular to the second axis to allow the second light beam to scan in the space, wherein the rotation axis perpendicular to the second axis and the rotation axis perpendicular to the first axis are parallel to each other;
• a signal transceiver;
• a controller, electrically connected to the first laser module, the first rotating module, the second laser module, the second rotating module and the signal transceiver;
• and
• a substrate, wherein the first laser module, the first rotating module, the second laser module, the second rotating module, the signal transceiver and the controller are disposed on the substrate,
• wherein when the first light beam is first projected on a UAV, the UAV sends a signal, and after the signal transceiver receives the signal, the controller obtains a first included angle, and when the second light beam is further projected on the UAV, the UAV sends the signal, and after the signal transceiver receives the signal, the controller obtains a second included angle and calculates a relative location, and controls the signal transceiver to transmit a relative location signal to the UAV, wherein the first included angle is an included angle between the first light beam and a connection line, the second included angle is an included angle between the second light beam and the connection line, the connection line is a connecting line between the first laser module and the second laser module, and the relative location is a location of the UAV relative to a landing location on the substrate.
