Research and Application of UAV for Measuring Depth
A rotor unmanned aerial vehicle(UAV)airborne sonar depth measurement system has been developed for complex water con-ditions such as high flow velocity and numerous reefs in deep and narrow river sections of high mountain and canyon areas.The system in-tegrates the UAV with the depth measurement sonar,and uses the UAV to hover above the water surface and the sonar depth measurement e-quipment to probe into the water to obtain depth data.The GNSS differential positioning technology combined with water depth data is used to obtain real-time coordinates and elevations of underwater points,And explore the application prospects of the equipment based on project ap-plication cases,summarize the shortcomings,and provide suggestions for further optimization and improvement.
