[0016] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0017] See attached figure 1 And attached figure 2 , a kind of theodolite external field infinite distance correction method of the present invention:
[0018] Step 1: self-calibrating the self-collimating collimator 3 by using a high-precision plane mirror 2;
[0019] The high-precision plane mirror 2 is placed along the direction of the optical axis of the self-collimating collimator 3, the mirror surface of the high-precision plane mirror 2 is parallel to the optical axis of the self-collimating collimator 3, and the reticle on the self-collimating collimator 3 can be positioned along the Move in the direction of the optical axis of the self-collimating collimator 3, and adjust the position of the reticle until the return image of the high-precision flat mirror 2 on the reticle reaches the clearest, that is, the self-calibration of the self-collimating collimato...
