Abstract: For the problem that in a certain type of aircraft flight test, the conventional airborne image measurement method can not be used to accurately calculate the eccentric positioning distance during aircraft running, a set of image measurement scheme based on ground multi-camera field stitching was designed.Through installing the high-speed camera array at the runway side, the high-speed camera control network was composed to achieve the full coverage of the image during aircraft running.By using the way of multi-camera intersection relay measurement and data stitching, the measurement of aircraft eccentric positioning distance was achieved. The simulation results show that using this program the maximum measurement error of aircraft eccentric positioning distance is less than 3 cm, which can meet the flight test accuracy requirements.
