When breaking imaging rules leads to out-of-focus, we need the machine vision system to adjust its optical parameters quickly and intelligently. So we can get clear and usable images. On the other aspect, out-of-focus only depends on the optical parameters which contain the depth information of objects. By using the information, we can recover the three-dimensional image of the objects.
