[0002] A surveying instrument is a high-tech measuring instrument that integrates optics, mechanics and electronics. It is a surveying instrument system that integrates horizontal angle, vertical angle, distance and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical degree disk with a photoelectric scanning degree disk, and replaces the manual optical micrometer readings with automatic recording and display of readings, which simplifies the angle measurement operation and avoids the occurrence of reading errors. Surveying instruments are widely used in construction projects.
