Abstract: A ball retainer is provided. The ball retainer includes a chain belt, a hook portion, and a recess portion. The chain belt has a first end and a second end. The hook portion is disposed at the first end. The recess portion is disposed at the second end. An outer circumferential side and an inner circumferential side are formed after the hook portion of the ball retainer is snapped into the recess portion. During operation of the ball retainer after the hook portion is snapped into the recess portion, an acting force is applied to the chain belt so that the hook portion is disengaged from the recess portion. During operation of the ball retainer after the acting force disappears, the first end and the second end of the chain belt approach each other so that the hook portion is accordingly snapped into the recess portion.

Abstract: A three-dimensional (3D) scanning system includes a projector that generates an emitted light projected on an object, a reflected light being reflected from the object; a sensor that generates image data according to the reflected light; and a depth processor that generates depth data according to the image data and at least one modified factor representing corresponding deviation amount between the image data and an ideal image data due to a circle of confusion caused by the reflected light passing a lens of the sensor and then irradiating a sense plane of the sensor out of focus.
