| Abstract: | The total measuring angular precision of a high-speed photoelectric theodolite is a complex functional relation,which depends on different factors.A full analysis of the measuring angular precision of a high-speed photoelectric theodolite that adops a continuous zoom lens is made.First,the total measuring angular precision of the device is classified.Next,the reticule tilt that arises from the working of the high-speed zoom lens and focal length correction factor are theoretically analyzed.Based on examples... |
