Application of Error Design Idea to Deal with the Shafting Error of Photoelectric Theodolite
The method to deal with the Shafting Error of photoelectric theodolite was designed according to the error design idea. The effect law between azimuth angle measure error of photoelectric theodolite and shafting error was studied based on MATLAB, and the simulating result reveals that the affect to azimuth angle measure error by each of the three-axis error was separately, and the final affect result can be account by adding each of the result, and the affect by collimation axis error and abscissa axis slop error can be eliminated by the normal-reversed measure method. According to the result above, the method for amending the azimuth angle measure error of photoelectric theodolite was proposed, and the Matlab simulating result proved the method is feasible.
