Accurately obtaining, processing, and transmitting actual data in disaster areas is an urgent issue that needs to be addressed in emergency surveying and mapping. In order to improve the accuracy of regional drone aviation emergency surveying and mapping, a regional drone aviation emergency surveying and mapping system is designed using tilt photogrammetry technology from both hardware and software aspects. Design sensors, drivers, and aviation controllers to ensure that drones can fly according to designated routes, install tilt camera components to provide hardware support for tilt photogrammetry technology, adjust drone aviation engines to ensure flight power, and perform special handling of hardware equipment according to emergency situations. In the surveying area, plan the navigation trajectory of the drone and use oblique photogrammetry technology to obtain regional image data. Pre processing of the initial image is achieved through two steps: uniform light and color, and distortion correction. Calculate the geometric data of the main body of the area, and obtain the emergency mapping results of the system through mapping and annotation. The system testing results indicate that the designed system has a larger surveying range, with surveying errors of approximately 0.7 km2 and 1.2 km2 for the main area and position, respectively, which can effectively improve the accuracy of regional unmanned aerial vehicle aviation emergency surveying.
