Problems solved by technology
[0005] The first technical problem to be solved by the present invention is to provide an adaptive iris recognition device; the device solves the problem that the current existing iris recognition device cannot be used by users of different heights through the cooperation of the wide-field camera and the lifting and rotating rod. At the same time, it solves the problem that the user needs to go to the front of the device to complete the recognition, and the device also solves the problem that the existing iris recognition device has a slow recognition speed or even refuses to recognize it under strong light, weak light or even no light. problems, as well as problems such as the reduction of luminous efficiency and the drift of luminous spectrum when the infrared light source works for a long time
[0006] The second technical problem to be solved by the present invention is to provide a method for iris recognition using the above-mentioned iris recognition device; The existing iris recognition device cannot adapt to the use of users of different heights, and at the same time solves the problem that the existing recognition device requires the user to walk in front of the device to identify, and through this method, the iris can be detected without any cooperation from the user. Recognition, which shortens the process that users need to repeatedly adjust the position to complete iris recognition in the past, and improves the user experience

The invention discloses an adaptive iris recognition device, which comprises a lifting rotating rod and a first casing arranged on the lifting rotating rod. The first casing is provided with a central processing unit, an iris collector, a sounding device and an iris collecting device. The motorized lens matched with the device; along the circumferential direction of the lifting and rotating rod, four face detection devices are evenly arranged, and the face detection device includes a second housing, which is equipped with an Connected wide-field camera. The present invention solves the problem that the current existing iris recognition device cannot be used by users of different heights through the cooperation of the wide-field camera and the lifting and rotating rod, and at the same time solves the problem that the user needs to walk in front of the device to complete the recognition in the past.
Description
technical field [0001] The invention relates to an adaptive iris recognition device and an iris recognition method using the device. Background technique [0002] As a new means of identity authentication, iris recognition technology is gradually entering people's lives. Since iris recognition technology has many advantages such as: non-contact acquisition, high recognition accuracy, and live detection, it is gradually favored by people. At the same time, there are more and more iris recognition products on the market, which are used to collect people's iris information for the iris recognition process. [0003] At present, there are many types of iris recognition products on the market, but they all have the following defects: 1. They cannot adapt to the needs of users of different heights. Even the iris recognition products with angle adjustment function require users to bow their heads to cooperate; 2. Existing The iris recognition products of the company require the us...
