    Abstract: Aiming at the photoelectric test requirements of the ground minimum control speed flight test, a photoelectric test method based on the combination of airborne photogrammetry and ground photoelectric tracking measurement was proposed. Firstly, the design of photoelectric test system for ground minimum control speed flight test was briefly introduced. Secondly, the methods and principles of system calibration, automatic ground tracking target detection, aircraft eccentricity measurement based on airborne photography and aircraft track and speed measurement based on photoelectric tracking measurement were discussed in detail. Then, the implementation process of flight test was summarized. Finally, the flight test verification was carried out. The test results show that the method is effective and reliable. It can provide an intuitive video of the aircraft side deviation process, and realize the positioning and measurement accuracy of ground static verification with aircraft deviation from runway direction better than 2 mm, elevation direction better than 2 cm and heading better than 5 cm. It fully meets the requirements for data integrity, intuitiveness, accuracy and reliability of the photoelectric test for the ground minimum control speed flight test.
