Abstract
The invention provides a pointing device assisting in light path butt joint of a theodolite and a target and a light path butt joint method, relates to the field of photoelectric measurement, and resolves the problem that blindness exists in light path butt joint operation caused by the unknown direction of emergent rays of the target in an existing light path butt joint method of the theodolite and a dynamic target. The pointing device can point out the direction of the emergent rays of the dynamic target, both target moving and target inclined angle adjustment have quantitative bases, and the blindness of the light path butt joint operation is reduced. According to the pointing device and the light path butt joint method, transitional light spots are generated by means of a laser pen, the dependency degree for the working environment is low, operation can be carried out at any time intervals all day, and effects are the same; the dependency degree for experience of operating staff in the light path butt joint process of the theodolite and the dynamic target is significantly reduced; meanwhile a target light source is not needed to be normally powered-on in the light path butt joint process of the theodolite and the dynamic target, and the light source is just opened to work after the target is aligned; and convenience is brought to the light path butt joint operation by means of deflection of a reflector base of the dynamic target.
Description
Technical field
The present invention relates to the photoelectric measurement field, be specifically related to the indicator device that a kind of auxiliary transit docks with the dynamic target light path, and transit and the quick light path docking calculation of dynamic target of using this indicator device.
Background technology
Dynamic target is a kind of device at indoor detection photoelectric tracking measuring equipment, and it can produce the parallel optical signal of simulation infinite point moving target, the indoor pick-up unit that carries out servo tracking for TV tracker system such as electro-optic theodolites.
During theodolite testing commonly used dynamic target mainly by A-frame and dynamically spiral arm two parts form, wherein there is screw pair at three fulcrum places contacting with ground of A-frame, can regulate the inclination angle, space of whole target.The dynamic rotary arm portion moves in a circle around the rotating shaft on A-frame top, arranges successively light source, lens combination and catoptron on the spiral arm.
After transit is finished the optical-mechanical system assembling, before the debugging servo tracking system, at first need to finish the light path docking of transit and dynamic target.So-called light path docking, be exactly that the spiral arm of dynamic target is when moving in a circle, transit is by adjusting orientation and pitch attitude, the CCD camera all can capture light source through lens combination and catoptron imaging, and namely transit three axles (Z-axis, transverse axis and the optical axis) intersection point is the summit of dynamic target rotation light cone.
At present, transit with the common method that the dynamic target light path is docked is: first with the dynamic target integrated moving near transit, open light source, then taking the peripheral space zone of a blank sheet of paper before the transit camera lens to move around to seek the hot spot that the target projection comes (generally needs ambient light very weak, such as evening), judge the corresponding deviation of facula position and transit lens location, then moving target mark position or adjust the inclination angle of target, seek again the hot spot of target projection after the adjustment with blank sheet of paper, judge the deviation of facula position and transit lens location, moving target mark is so repeated multiple times again, just transit can be docked with the light path of target.In the said process, generally select dynamic target 0 ° and 180 ° of two positions as feature locations, in these two positions transit is docked with the light path of target, then on the whole circular path of target, transit can well capture dynamic target.
The light path docking calculation of above-mentioned transit and target Shortcomings aspect following four: one, because hot spot is difficult to identification, above-mentioned light path mating operation seriously relies on staff's experience, the unfamiliar personnel operation in this field is got up gruelling, and is also very time-consuming; Two, there is certain randomness at position and the inclination angle of adjusting the target frame according to the distance of hot spot and transit lens barrel on the range estimation paper, belong to and repeatedly adjust qualitatively the infinite approach ideal position; Three, responsive to the light-dark ratio of workplace, the hot spot that projects on the paper only just can be seen when light is dark; Four, need to keep target light source Chang Liang, can't carry out the light path mating operation of transit and target in the situation that power failure or target light source break down.
Summary of the invention
The present invention has now in transit and method that the dynamic target light path dock owing to the unknown of target emergent ray direction for solving, thereby cause the light path mating operation that the problem of certain blindness, the indicator device and the light path docking calculation that provide a kind of auxiliary transit to dock with the target light path are provided.
The indicator device that auxiliary transit docks with the dynamic target light path, this device comprise circular orientation frame, the first protractor, the first little pointer, the second protractor, the second little pointer, the 3rd protractor, large pointer, laser pen and the 4th protractor;

The method that auxiliary transit docks with the target light path, the method is realized by following steps:
The position of step 1, adjustment dynamic target and transit, the fixed angle α of record dynamic target pivot arm platen surface and mirror unit installed surface;
The inclination angle of dynamic target is also adjusted in step 4, mobile dynamic target position, makes large pointer direction and transit body tube installation direction on same straight line; Light laser pen, adopt blank sheet of paper before the transit camera lens, to accept the hot spot of laser pen projection, judge whether hot spot is incident upon in the camera lens, if so, then execution in step five, if not, continue mobile dynamic target position and adjust the target inclination angle, until the dot projection of laser pen is in the transit camera lens;
Beneficial effect of the present invention: indicator device of the present invention can indicate the emergent ray direction of dynamic target, and there has been quantitative basis at moving target mark and adjustment target inclination angle, have reduced the blindness of light path mating operation.The present invention adopts laser pen to produce the hot spot that can accept, and is low to the working environment degree of dependence, but any period operation of whole day, and effect is identical; The present invention reduces in transit and the dynamic target light path docking operation degree of dependence to operating personnel's experience; Simultaneously transit and dynamic target light path docking operation do not need target light source Chang Liang, open light source behind the bornb sight and work on and get final product; The mirror unit of the present invention by the deflection dynamic target carries out the light path mating operation provides convenience.
