UNMANNED AERIAL VEHICLE POSITION MEASUREMENT SYSTEM, AND POSITION MEASUREMENT METHOD

Japanese Patent JP2022185210

A

To make it possible to fly an Unmanned Aerial Vehicle (UAV) stably and continuously when flying the UAV using a position measurement system of the UAV with use of a total station (TS).SOLUTION: A TS installed on the ground, a UAV having an optical reflector loaded thereon, and an aviation monitor control device (PC) are communicatably connected. The TS is configured to receive reflection light, which is irradiation light radiated toward the UAV, reflected by the optical reflector loaded on the UAV, and returns, measure a current position (TS) of the UAV, and transmit the measured current position to the PC. The PC is configured to, when receiving the current position (TS), transmit (transfer) the received current position to the UAV. The UAV is configured to fly using the current position (TS). When the TS loses the UAV, the PC is configured to transfer a current position (EKF) sent from the UAV, to the TS. The TS is configured to control a direction of the irradiation light on the basis of the current position (EKF) sent from the PC, and resume tracking the UAV.SELECTED DRAWING: Figure 9
