Abstract

A new method of attitude measurement of the calibration target based on machine vision is proposed in this paper. Firstly, the internal parameters and external parameters of the CCD camera are calibrated by using the feature points on the calibration target. Secondly, shoot the calibration target in different positions and gather any different image information. Finally, measure the calibration target's attitude through reconstructing the positions of those feature points which on the calibration target. Experiment results show that the standard deviation of the attitude measurement errors is less than 10 arc-second. This method is an effective high-precision space attitude measurement algorithm which can meet the engineering requirements.
