  "textContent": "The present disclosure provides a system and a method for measuring water capacity of polar lakes, and relates to the technical field of lake water capacity measurement. The method comprises the steps: controlling an unmanned aerial vehicle to move along with an unmanned underwater vehicle at a preset height right above the unmanned underwater vehicle by utilizing an ADRC algorithm; obtaining lake surface point cloud data, under-lake point cloud data and under-lake single-beam ranging data so as to construct a water three-dimensional topographic map, a lake coastal three-dimensional topographic map and a lake bottom three-dimensional topographic map under the same coordinate system, and then determining the lake water capacity. By arranging the unmanned underwater vehicle, an unmanned underwater vehicle-mounted module, the unmanned aerial vehicle and an unmanned aerial vehicle-mounted module, lake elevation and lake underwater terrain data are automatically measured, so that the observation precision of polar lakes is improved.",
