  "textContent": "The present disclosure is related to an unmanned aerial vehicle-mounted continuous variable-frequency blue-green laser radar for water depth survey, including a blue-green light variable-frequency laser, a laser power supply driver, an encoding motor, a reflective optical wedge, a reflector, a big lens, a small lens, a balanced light detection module, a high-speed laser acquisition processor, an IMU module, an RTK module, a 4G module, a controller, a 4G antenna, a server, a mobile phone terminal and the like according to a characteristic that continuous variable-frequency blue-green laser generates frequency change when encountering a water surface and a water bottom, convolution and fast Fourier transform and a time-frequency correspondence. The laser radar is small in size, light in weight and suitable for an unmanned aerial vehicle to survey a water depth rapidly and precisely, achieves a millimeter-level precision, and realizes 0-10 m water depth survey.",
