Background

Theodolite is a measuring instrument designed according to the principle of goniometry for measuring horizontal and vertical angles, and is divided into two types, optical theodolite and electronic theodolite, the most common being electronic theodolite. The theodolite is a mechanical part of the telescope, which enables the telescope to point in different directions. The theodolite is provided with two mutually vertical rotating shafts so as to adjust the azimuth angle and the horizontal height of the telescope. The theodolite is an angle measuring instrument equipped with a telescope, a horizontal scale and a reading index, and a vertical scale and a reading index. The original invention of theodolite has a close relation with navigation. In the fifteen-sixteen century, developed countries such as the united kingdom and france need to draw various maps and chart for reasons of navigation and war. The earliest methods for drawing maps used triangulation, which is to determine the position of a third remote point from the observation results of two known points, but because of the absence of suitable instruments, the angle measurement method is limited, the accuracy is not high, and the accuracy of the maps drawn is not high. The theodolite improves the observation precision of the angle, simplifies the measuring and calculating processes and provides more accurate data for drawing a map. Theodolites have since been widely used for surveying various engineering constructions.
