Pellet's position is the key of ICF experiment. The paper introduces an automatic positioning system
and also describes an image processing method which is used to achieve the pellet's automatic positioning. Based on the theory of distance measurement by defocusing
the spotting in two dimension of rotation and pitch
and one dimension of translating by using the improved focusing evaluation function which is the combination of variance and Brenner have been realized
respectively
and the spotting of translating in three dimensions has also been implemented by detecting the mass center.
