Abstract
A method for scanning an object having depths is provided, using a plurality of rod lenses to limit the blurring range of a contour image of an object having depths to enable an image capture unit to capture an identifiable contour image, wherein either of the diameter of each rod lens and the spacing between the rod lenses is smaller than the average width of the target. A scanning system for scanning an object having depths is also disclosed herein.
Claims12
A method for scanning an object having depths, comprising steps:
- using a light source to illuminate an object to generate a plurality of imaging lights respectively having different depths of field, wherein said object has a target having a depth;
- using a plurality of rod lenses to receive the plurality of said imaging lights from a plurality of visible regions of said rod lenses and output a plurality of localized imaging lights to a plurality of imaged areas, wherein either of a diameter of said rod lens and a spacing between said rod lenses is smaller than an average width of a contour of said target, and wherein all said imaged areas are identical in size;
- and
- using an image capture unit to capture the plurality of said localized imaging lights to form a corresponding contour image.

A system for scanning an object having depths comprising
- a light source used to illuminate an object to generate a plurality of imaging lights respectively having different depths of field, wherein said object has a target having a depth;
- a plurality of rod lenses disposed side by side with optical axes thereof parallel to each other, used to receive the plurality of said imaging lights from a plurality of visible regions of said rod lenses and output a plurality of localized imaging lights, wherein either of a diameter of said rod lens and a spacing between said rod lenses is smaller than an average width of a contour of said target, and wherein blurred ranges of said localized imaging lights are identical in size;
- and
- an image capture unit disposed at a light output side of the plurality of said rod lenses to capture the plurality of said localized imaging lights to form a corresponding contour image.
