The invention discloses a high-stability-precision two-shaft three-frame mechanism of a photoelectric system, and belongs to the field of structural design of airborne photoelectric systems. Comprising an azimuth rotating shaft system and a pitching rotating shaft system which are mutually orthogonal, and three frames for carrying the rotating shaft systems, the azimuth rotating shaft system is divided into an outer azimuth shaft system and an inner azimuth shaft system; the three frames are an outer orientation frame, an inner pitching frame and an inner orientation frame in sequence from outside to inside; the outer orientation shaft system is arranged on an orientation rotating shaft of the outer orientation frame, the pitching rotating shaft system is arranged between the outer orientation frame and the inner pitching frame and located on a pitching rotating shaft of the inner pitching frame, and the inner orientation shaft system is arranged between the inner pitching frame and the inner orientation frame and located on an orientation rotating shaft of the inner orientation frame. According to the invention, miniaturization and light weight of the photoelectric system are realized comprehensively, limitation of over-top tracking is avoided, vibration decoupling can be realized, and the photoelectric system has high stability precision.
