Abstract:Traditional UAV positioning system error elimination technology has the problem of error elimination and low accuracy. We need to further study the technology of remote sensing positioning system error elimination for light and small UAVs. According to the light and small UAV route, and the initial position of geographical reference coordinate system, the construction of the light and small UAV remote sensing positioning model; using the model to analyze the target positioning principle, through the model and the UAV secret flight characteristics, the target position conversion, coordinate position information is obtained after conversion, the UAV flight posture the change range of precision, error correction and image sequence acquisition, thereby completing the system error elimination. The experimental results show that the precision of the error elimination is high.
