Rocket Rolling Attitude Determining Method Based on Optical Tracking Measurement

The rocket attitude is used to describe the attitude and state of the carrier rocket moving around its mass center and is also an important parameter used to evaluate the stability of the rocket movement. Aimed at the problem that it is difficult to determine the optical tracking measurement-based rocket rolling attitude, special positions in the rocket video image are selected skillfully to perform the measurement interpretation, establish corresponding rolling attitude calculation model, model and analyze the carrier rolling attitude changes caused by the measurement interpretation error. This method not only expands the data processing method used to select the rolling attitude measurement for interpretation, but also provides effective judging basis for analyzing, evaluating and improving the rocket performance.
