Study on stable tracking target with single photoelectric theodolite

In order to solve the stable transition of the single photoelectric theodolite when the target picking-up characteristics are lost in a short time, the moving trace of the target in single theodolite is studied in detail. With the existing data performing optimal polynomial approximation in section and extrapolation for the moving trace of the target, a stable transition of the equipment can be carried out. The results show that this method can ideally solve the stable tracking problem for target when the target is lost in a short time (2-3s).
