Coordinate conversion error analysis of photoelectric detection targets on tethered lift-off platform

The target orientation technology of tethered lift-off platform has been widely used in the military and civil fields. The orientation performance has become an important index to evaluate the comprehensive performance of unmanned aerial vehicle (UAV) and tethered lift-off platform. The precision test research of photoelectric detection system was carried out, the emphasis was high precision orientation error analyses about the target, the photoelectric detection system error transformation model was deduced, and the error conversion coordinates were verified by simulation. By Monte Carlo thought, the influence of error parameters is analyzed to the orientation accuracy of the photoelectric detection system, and the method about target’s high precision orientation is improved, which provides a theoretical basis for target orientation accuracy and high precision design about photoelectric pod of unmanned lift-off platform.
