Abstract
A kind of infinity range correction method in theodolite outfield of the invention, solves the technical problem that prior art has larger error to the focusing of big-and-middle-sized theodolite outfield；The present invention comprises the following steps：Step one：Self calibration is carried out to auto-collimation collimator using high precision plane mirror：Level crossing is placed along auto-collimation collimator optical axis direction, and minute surface is vertical with the optical axis of auto-collimation collimator, the position of graticle on adjustment auto-collimation collimator, until the return picture of level crossing on graticle is most clear；Step 2：Using the auto-collimation collimator after being calibrated as infinity apart from benchmark, pair warp and weft instrument focusing system carries out infinity range correction：The optical axis of theodolite is parallel with the direction of auto-collimation collimator optical axis, and the clear aperture of theodolite and the clear aperture of auto-collimation collimator are mutually corresponding, pass through the optical system observing graticle image of theodolite, and the position of the focusing component on theodolite is adjusted, until graticle image is most clear.
Description
Technical field
The invention belongs to photoelectric monitoring field, and in particular to a kind of theodolite outfield infinity range correction method.
Background technology
At present, big-and-middle-sized theodolite is focused, many combinations focused using distance focusing with temperature.Wherein influence temperature
The factor for spending accuracy of focusing is a lot, including due to linear expansion coefficient disunity, difference caused by combining structure material diversity
Layer temperature influences bad determination of uneven, temperature sensor location etc..And then the temperature focusing zero obtained by theoretical calculation
There is larger error in point.
The content of the invention
It is an object of the invention to provide a kind of theodolite outfield infinity range correction method, prior art is solved to big-and-middle
Type theodolite outfield, which is focused, has the technical problem of larger error.
A kind of infinity range correction method in theodolite outfield of the invention：
Step one：Self calibration is carried out to auto-collimation collimator using high precision plane mirror：
High precision plane mirror is placed along auto-collimation collimator optical axis direction, and high precision plane mirror minute surface is put down with auto-collimation
The optical axis of row light pipe is parallel, the position of graticle on adjustment auto-collimation collimator, until high precision plane mirror on graticle
It is most clear as reaching to return,
The return picture of level crossing image during the position of regulation graticle is clear by obscuring on the graticle, then
It is from clear to fuzzy；
Step 2：Using the auto-collimation collimator after being calibrated in step one as infinity apart from benchmark, pair warp and weft
Instrument focusing system carries out infinity range correction:
The optical axis of theodolite is parallel with the direction of auto-collimation collimator optical axis, and the clear aperture and auto-collimation of theodolite
The clear aperture of parallel light tube is mutually corresponded to, and by the optical system observing graticle image of theodolite, and is adjusted on theodolite
Focusing component position, until graticle image is most clear,
Graticle image image during the position of regulation theodolite focusing component is clear by obscuring, then
It is from clear to fuzzy.
The advantageous effects of the present invention：The present invention is first by high-precision level crossing to auto-collimation collimator self-correcting
Standard, after the range correction of outfield infinity is carried out with the auto-collimation collimator pair warp and weft instrument that is calibrated, temperature is reduced to greatest extent
Change the influence to focusing system, it is ensured that theodolite accuracy of focusing.
