英文摘要：

In this article, the principle and the method of ordinary optical alignment was analyzed. And it proposed a method based on intelligent total station instrument optical alignment, for improving the defects of the optical collimation surveying method in engineering survey. The precision was tested to apply to the high accuracy position transmission and the preserved position datum in the engineering surveys. According to the comparison of the data, the difference of the collimation between the value based on the intelligeng total station instrument optical alignment method and the value based on Outer-target Method was less than 2＂, the collimation difference between the value based on Outer-target Method law and the value based on the cross silk method was also less than 2＂ . And the performance of VAR and concentricity based on the intelligent total station instrument optical alignment method was better than the traditional methods. The analysis showed that the intelligent method proposed in this paper was accurate, reliable, and useful, and could be applied in commercial measurement.
