When using a monocular camera for detection or observation, one only obtain two-dimensional information, which is far from adequate surgical robot manipulation and workpiece detection. Therefore, at this scale, obtaining three-dimensional information of the observed object, especially depth estimation surface points each has become key issue. This paper proposes two methods to solve problem def...

Abstract Due to chromatic aberration, blue images are defocused when the eye is focused middle of visible spectrum, yet we normally not aware blur. The suffers from monochromatic aberrations which degrade optical quality all projected on retina. combination and additive these may interact improve image quality. Using Adaptive Optics, investigated visual effects correcting viewing polychromatic ...
