ing at the limitation of the measurement conditions in most of the measurement implementation experiments, a method for measuring the binocular vision motion parameters based on dual cameras without points with the same name is proposed. The initial values of position and pose are calculated by the method, and the initial values are optimized by the global orthogonal iterative algorithm. The measurement method does not need the participation of the same name point in the realization process, but only needs more than 6 target cooperative mark points in the field of view of two cameras, so as to obtain the position and attitude parameters of the validator in the process of motion. The hovering, obstacle avoidance, and landing stage of the spacecraft are tested. The measurement method is compared with the binocular pose measurement method based on the same point, the monocular pose measurement method based on orthogonal iteration and the implied value of total station. The default value obtained by the station instrument is compared. The attitude measurement error is less than 0.5°, and the position measurement error is less than 0.01 m.
