Rapid surveying and mapping method and device

The invention provides a rapid surveying and mapping method and device, and belongs to the technical field of unmanned aerial vehicle surveying and mapping. The method comprises the steps that: initial surveying and mapping information of an operation plot on an electronic map is determined according to the operation plot, wherein the initial surveying and mapping information comprises a target surveying and mapping point; a flight path of an unmanned aerial vehicle is planned based on the target surveying and mapping point, wherein the flight path is a path traversing the target surveying andmapping point; the unmanned aerial vehicle is controlled to hover above the target surveying and mapping point according to the flight path, and return image data; the target surveying and mapping point is calibrated in real time based on the actual position information corresponding to the image data until the target surveying and mapping point in the flight path is calibrated; and accurate surveying and mapping informa
