AI Technical Summary
Technical Problem
Existing UAV positioning methods accumulate significant errors after long-term flight, affecting positioning accuracy.
Method used
By using HOG feature extraction based on the yaw angle rotation positioning satellite image and real-time captured image, the best matching region is determined. The HOG descriptors of the real-time captured image and the positioning satellite image are used for positioning to eliminate the accumulation of positioning errors.
Benefits of technology
It achieves real-time and accurate positioning of UAVs, avoiding the accumulation of errors after long-term flight and improving positioning accuracy.
