Abstract

The invention discloses iris acquisition equipment capable of expanding a view field range. Including a camera array, The infrared lighting unit and the control module. By using a camera array with the same object space focal length, the technical effects of expanding the collection plane and enlarging the view field range are achieved through a multi-data synchronous control algorithm, and a usercan complete image collection in a wider area without being limited by the narrow view field range of a single camera. Meanwhile, a multi-path data synchronous transmission method is adopted, and synchronous control and image splicing of multi-path data are achieved under the condition that a certain image transmission frame rate is guaranteed.

Description

technical field [0001] The invention relates to the field of iris collection, in particular to an iris collection device and method for expanding the field of view. Background technique [0002] Current iris recognition devices are often equipped with a single iris camera. Limited by the small field of view of the camera, if the user moves a little, the eyes may exceed the range of the camera's field of view, resulting in the inability to capture a complete binocular image. Traditional solutions include screen self-feedback, mirror feedback, small hole light source alignment, etc., prompting users to adjust themselves, actively cooperate to adjust the position of the eyes to the range that the device can collect, and complete binocular image acquisition. This method obviously reduces the user experience and causes difficulties for users who are not familiar with the working principle of the device. Contents of the invention [0003] In view of the above problems, the pres...
