摘要: A guide can provide proper registration of an object such as a hand above a scanner device for imaging. The guide can include windows or slits so that the scanner device can produce an image such as a finger or palm in a natural state rather than being pressed against, for example, a flat surface such as glass. Thus, registration of a palm and/or a finger in the guide can be used to produce non-distorted high quality images of biometric patterns in their natural 3-dimensional state.
摘要翻译: 引导件可以提供诸如在扫描仪装置上方的手的对象的适当配准以进行成像。 引导件可以包括窗口或狭缝,使得扫描器装置可以以自然状态产生诸如手指或手掌的图像,而不是被压靠在诸如玻璃的平坦表面上。 因此,手指和/或手指在引导件中的配准可用于在其自然的三维状态下产生生物特征图案的非变形的高质量图像。
