Iris acquisition method and device

Abstract

The invention discloses an iris acquisition method and device. The method is utilized to indicate the position of a user through utilizing a positioning laser beam, user iris acquisition can be accurately realized through the iris acquisition device, movement frequency of the user in an iris acquisition process can be reduced, and user experience is improved. The method comprises steps that the positioning laser beam is generated according to preset conditions, and the positioning laser beam is used for indicating the position of the user; a first iris image of the user is acquired; the first iris image is processed to acquire the first iris image information; whether the first iris image information is complete is determined; if not, the first adjustment information is generated; adjustment is carried out according to the first adjustment information, and a second iris image of the user is acquired.

Description

technical field [0001] The invention relates to the field of biological feature identification, in particular to an iris collection method and device based on laser positioning. Background technique [0002] Iris recognition technology is a technology for recognition and comparison through the characteristics of the iris of the human eye. , image normalization, image enhancement), and then use a specific algorithm to extract the features required for iris recognition from the processed image and encode them, and finally match the extracted feature codes with the iris feature codes in the database to achieve identity recognition. The high stability and independence of the iris is the basis for identification, and iris recognition technology has therefore become the most accurate and promising biometric technology. [0003] The collection of iris images greatly affects the final recognition effect. With the gradual development of commercial iris recognition, the requirements ...

Problems solved by technology

[0003] The collection of iris images greatly affects the final recognition effect. With the gradual development of commercial iris recognition, the requirements for real-time and convenience of image collection are also increasing. To collect clear iris images, iris recognition equipment needs User assistance, most of the coordination process needs to be adjusted repeatedly, so that the human eye can be fixed at a certain position to facilitate collection, and the repeated adjustment process makes the customer experience not good
