Unmanned aerial vehicle land terrain flowing type accurate surveying and mapping method, equipment, medium and product

The invention discloses an unmanned aerial vehicle land terrain flowing type accurate surveying and mapping method, equipment, a medium and a product, and relates to the technical field of terrain surveying and mapping, the method comprises the following steps: determining regional terrain data of a target region by adopting a real-time dynamic differential positioning technology according to image control point three-dimensional coordinate data of the target region and position information of an unmanned aerial vehicle; according to the three-dimensional coordinate data of the image control point and the regional topographic data, correcting the regional topographic data of the non-signal region in the target region by adopting a real-time dynamic differential positioning technology to obtain the corrected regional topographic data of the non-signal region; and by using a GIS integration method, combining the topographic data of the signal area in the target area and the corrected topographic data of the non
