HANDHELD IRIS IMAGING APPARATUS AND METHOD |
摘要 |
A compact, handheld imaging apparatus which can be used to capture high-quality iris images for identification of a person. The handheld iris imager is non-invasive and non-contacting and comprises a camera, a cold mirror, a lens, and an illuminator. The imager has sensors and indicators which assist a user in aligning and focusing the device. The imager also automatically captures the image when proper positioning is achieved. A template representative of the iris features is extracted and then compared to a database of previously stored templates to identify the person.
