  • The measuring precision of an electro-optical theodolite will fall down when the target moves relatively the measuring device. Moreover, the precision falling is more dependent on the speed of the relative movement. To improve the measuring precision of the electro-optical theodolite, this paper researches the reasons of above phenomena based on the TV exposure principle and proposes a new method to improve the data processing accuracy. The data matching algorithm based on the target missing and encoder position is proved in a simulation, and its feasibility for operating is also analyzed. The experimental results show that the algorithm can improve the measuring precision of the electro-optical theodolite by 20%~30%, which means that the measuring precision improves from 1/2 to 1/3 pixel of CCD.
