1.3.1 Post-flight upload verification

✅ After completing a drone flight, image upload and analysis are performed on the platform. In order to process the images collected by the drone into the data required for the field, it is necessary to check that the collected images have been uploaded properly. It takes about half a day to generate orthophotos and 3D models through a self-developed engine. Try using online data to digitize offline construction sites.
