| Abstract: | Under the background of the plane displacement monitoring, this article elaborates the misapprehension meaning of the precision of the distance intersection from front, and introduces the compensation calculation method of the meteorology correction value of distance measurement and the instrument designed to ascertain instrument height for the sake of comparing the variation of the distance measured in each period of time. In addition, the article has some reference value to the job of distance measurement of high precision as well. |
