Embodiment Construction

[0023] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0024] The steps of this azimuth reference mirror calibration method are:

[0025] ⑴Establish the autocollimation theodolite

[0026] ① Place the autocollimating theodolite at a proper position in front of the dividing head, so as not to hinder the operation of the dividing head and the installation and adjustment of the azimuth reference mirror. The self-collimating theodolite in the present embodiment is the Leica TM5100A self-collimating theodolite, and the angle measurement accuracy is 0.5 ". The dividing head in the present embodiment is a laser subdividing multi-tooth dividing head, and the laser subdividing multi-tooth dividing head It is a turntable placed vertically, and the surface of the turntable is made with scales.

Abstract

The invention relates to a method for calibrating an azimuth reference mirror. The method for calibrating the azimuth reference mirror comprises the following steps of: (1) erecting an auto-collimation transit; and (2) calibrating the azimuth reference mirror. The method for calibrating the azimuth reference mirror has a scientific and reasonable design, is easy and convenient to operate, and has high installation accuracy, and the calibration result is accurate; the field calibration is not needed, and the azimuth accuracy is guaranteed by the parallelism precision of an installation foundation, a mirror surface, and an installation bottom of the azimuth reference mirror.

Description

technical field [0001] The invention relates to a calibration method for the mirror surface normal of an azimuth reference mirror and an installation surface, in particular to a calibration method for an azimuth reference mirror. Background technique [0002] The azimuth reference mirror is an optical device whose main component is an optical flat mirror. The azimuth reference mirror is usually installed on the inner wall of the ship cabin, and the bow and stern lines of the ship are represented by the mirror normal; it can also be used indoors to represent a fixed optical azimuth reference. At present, the following method is commonly used when installing the azimuth reference mirror: firstly install the azimuth reference mirror in an appropriate position, and then adjust the adjustment mechanism on the mirror body to align the normal line of the mirror surface with the azimuth reference. This installation method requires on-site calibration, and the accuracy is guaranteed...
