| description | The invention provides a laser tracking attitude measurement system and method based on weighted least squares. The system comprises a laser tracking measurement unit, a monocular vision measurement unit and a target, wherein the target comprises a cube-corner prism and a photoelectric position sensor; the laser tracking measurement unit and the monocular vision measurement unit are respectively fixed at preset positions, and the target is fixedly placed on a measured object. The high resolution when a cube-corner prism and a photoelectric position sensor are used for measuring an azimuth angle and a pitch angle and the high sensitivity when monocular vision is used for measuring a roll angle are comprehensively utilized, and measurement of an attitude angle is completed based on the conversion relation of laser beam vectors among different coordinate systems through weighted least squares. According to the measurement system and method, the overall precision of laser tracking attitude measurement in a large- |
