Zusammenfassung:The embodiment of the invention provides cooperative target design and a corresponding attitude angle measurement system and method. A cooperative target employs the three-dimensional design, and comprises sixteen feature points with different heights, a cube-corner prism with a notch, a two-dimensional PSD, and a matching circuit. The attitude angle measurement system comprises the cooperative target, a monocular vision measurement unit, a laser tracking measurement unit and a calculation unit, in the attitude angle measurement process, the cooperative target is fixed on a measured object, and the monocular vision measurement unit and the laser tracking measurement unit are respectively fixed at the preset positions. The attitude angle measurement method comprises the steps of firstly measuring a rolling angle of the cooperative target through the monocular vision measurement unit, secondly, measuring the light spot coordinates according to the two-dimensional PSD in the cooperative target, and then calculat
