Abstract

The selection of focusing window is an important part in the process of auto-focusing ing of photoelectric theodolite. The selection method of focusing window of traditional photoelectric theodolite has the disadvantages of large amount of calculation, poor resistance to cockroach and poor adaptability. Aiming at this problem, the method of selecting the auto-focusing window of photoelectric theodolite is proposed, which is based on the off-target amount. The experimental results show that the method has a small amount of calculation, and the corresponding evaluation function curve has higher sensitivity. At the same time, it reduces the influence of the background on the focusing process, and meets the real-time and accuracy requirements of real-time auto-focusing of the moving target by the photoelectric theodolite.
