Method for installing and debugging rotary table by using laser gradienter

The invention discloses a method for installing and debugging a rotary table by using a laser level meter, and relates to the technical field of inertial navigation, and the method comprises the following steps: placing the laser level meter on the table top of the rotary table, and enabling the laser level meter to emit a horizontal laser beam and a vertical laser beam; adjusting the position of the laser level meter to enable the horizontal laser beam to irradiate the rotation center position of the rotary table; the offset condition of the vertical laser beam on the external equipment is observed, and the rotary table is adjusted according to the offset; the vertical laser beam is completely overlapped with the corresponding position of the external equipment; the rotary table is rotated by a certain angle, so that the vertical laser beam is irradiated to a preset position on the external equipment; the offset condition of the horizontal laser beam on the external equipment is observed, and the rotary tabl
