The invention discloses a map reconstruction method and system based on an unmanned aerial vehicle, transmission equipment and a storage medium. The method comprises the steps: transmitting picture data obtained by an unmanned aerial vehicle and an attitude parameter value and a position parameter value of the unmanned aerial vehicle corresponding to the picture data back to a ground station in real time, wherein the unmanned aerial vehicle attitude parameter value at least comprises the yaw angle of the attitude of the unmanned aerial vehicle and the yaw angle of the course of the unmanned aerial vehicle; rotating the picture data according to the difference between the unmanned aerial vehicle attitude yaw angle corresponding to the picture data and the yaw angle of the unmanned aerial vehicle route by using the ground station; and splicing the rotated picture data into a two-dimensional map according to a block matching method of preset picture data, displaying the two-dimensional map at an air route of the ground station according to the position parameter value corresponding to the picture data, and performing real-time two-dimensional map reconstruction. The technical problemthat real-time map reconstruction cannot be realized based on a rescue unmanned aerial vehicle is solved.
Description
technical field [0001] The present application relates to the fields of UAV emergency relief and map reconstruction, and specifically relates to a UAV-based map reconstruction method and system, transmission equipment, and storage media. Background technique [0002] When natural disasters such as earthquakes, landslides, mudslides, floods, etc. occur, emergency relief drones are used to collect and send back data to reconstruct disaster scene maps to provide assistance for rescue. [0003] The current mainstream data processing is to wait for the drone to fly, download the data, and perform puzzle processing. This kind of data processing has high precision, but the downloading and post-processing of the data takes as little as half an hour and as many as a few days. This kind of data processing method is not suitable for the scene of emergency disaster relief for timely drawing and providing the most real-time data reference for emergency disaster relief. Therefore, it ha...
