Electricity measurement of laser rangefinder
, Features: cheap, easy to manufacture, safety, low accuracy, high refractive index when intersecting with other substances. Infrared photoelectric rangefinders have the characteristics of low precision, weak flexibility, fast operation, and great influence by terrain. Photoelectric rangefinder, electronic theodolite and computer constitute electronic speedometer. It can measure the horizontal distance, horizontal angle and vertical angle at the same time at one station, so as to obtain the height difference and coordinate increment of the point to be set, and record the electronic data, so that all the measurement work of the measuring station can be completed automatically, which greatly simplifies the measurement Work.
