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.

Abstract: An image scanning system for scanning an object is disclosed. The image scanning system includes a light source, an optical lens, an image capturing unit and a light barrier element. The light source irradiates an object to produce an image light, and the optical lens converges the image light. The image capturing unit is disposed at a light leaving side of the optical lens, and the image capturing unit captures the image light to form an image. The light barrier element is disposed at a light entering side of the optical lens or disposed between the optical lens and the image capturing unit, and the light barrier element selectively allows the image light within a predetermined range of an incident angle to pass through.
