Multifunctional three-dimensional centering measurement auxiliary device

The invention discloses a multifunctional three-dimensional centering measurement auxiliary device which comprises a centering base fixing device, a centering base, a leveling base and a two-way connecting device, when the triangular leveling base is used, the two-way connecting device penetrates through a through hole, the upper end of the two-way connecting device is connected with a self-contained base of a measuring instrument, and the lower end of the two-way connecting device is connected with a prism. When the annular leveling base is used, a gyroscope host of the lower frame type gyroscopic total station can be fixed below the annular leveling base. The invention discloses a multifunctional three-dimensional centering measurement auxiliary device which can be used for simultaneously carrying out observation of control measurement on the same point measurement instrument and prisms on the premise that the prisms do not influence each other. High-precision free switching of the annular leveling base and
