On-the go touchless fingerprint scanner
First Claim
1. An on-the-go fingerprint scanner, comprising:
- a scanning area;
a beam break sensor disposed coincident to the scanning area such that the beam break sensor detects when an object passes through the scanning area;
at least one hand camera configured to capture a video image of the scanning area such that when the beam break sensor detects that an object has passed through the scanning area, the hand camera;
acquires an image of the object,detects whether the object is a human hand by determining a contour around the perimeter of the object, applying landmark points to the contour, and comparing the contour to a previously trained Active Shape Model of a hand,detects a location of any fingers on said detected hand by processing the location of the landmark points, anddetects the presence or absence of any fingers using a neural network; and
at least one fingerprint camera configured to receive the location of any fingers within the scanning area from the hand camera and capture a plurality of high-resolution images of at least a portion of any of said fingers passing through the scanning area.

Abstract
On-the-go fingerprint scanners and methods of capturing fingerprints on-the-go are disclosed. In some aspects, the on-the-go fingerprint scanner can include a scanning area and a beam break sensor disposed coincident to the scanning area such that the beam break sensor detects when an object passes through the scanning area. The scanner can also include at least one hand camera configured to capture a video image of the scanning area such that when the beam break sensor detects that an object has passed through the scanning area, the hand camera detects whether the object is a human hand and the location of any fingers on said hand, and at least one fingerprint camera configured to receive the location of any fingers within the scanning area from the hand camera and capture a high-resolution image of at least a portion of any of said fingers passing through the scanning area.
