Method for quickly obtaining field map according to surf-scan

Abstract

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 is facilitated. According to different areas of a reconstructed map, the shooting time is about 10-15 minutes, the map generation time is 2-5 minutes, and in other words, the map of the site can be completely obtained within half an hour.

Description

technical field [0001] The invention relates to the field of disaster site map survey, in particular to a method for rapidly obtaining a site map according to surf-scan. Background technique [0002] Traditional accident and disaster sites cannot quickly obtain a complete map of the site. Generally, manual surveying and mapping, high-altitude aerial photography, satellite remote sensing and other methods can be used to obtain the site map after the disaster. The common points of these methods are time-consuming and professional operators. High requirements and high costs. [0003] In the case of natural disasters, sudden accidents, etc., there is often not so much time, and it is also very important to obtain the on-site map, so it is very important to be able to quickly and conveniently obtain the on-site map data. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art, and provide a m...
