Method for quickly obtaining field map according to surf-scan

The invention relates to a system and method for quickly obtaining a field map according to surfscan, and the system is characterized in that the system comprises a high-altitude image scanning device, an information transmission module, and a central image processing module, and the high-altitude image scanning device comprises an aircraft control module, a propeller transmission module, and an image scanning module; the flight control module is used for driving the image scanning module to move at a high altitude, transmitting the image scanning module to equipment with a central image module through the information transmission module, carrying out algorithm comparison on feature points of collected images, and carrying out splicing processing on the images in combination with GPS information. Compared with other surveying and mapping and map-generating equipment, Surf-Scan only needs one tablet personal computer and one unmanned aerial vehicle to complete map splicing work, carrying of an emergency site i
