Problems solved by technology

[0006] However, in many cases, because the area of ​​the spot is too large, the entire eye or iris area is blocked, which directly leads to the failure of iris coordinate positioning, and it is impossible to detect the existence of iris coordinates or iris information, and it is impossible to locate the iris according to the spot positioning information. Information to adjust the position of the fill light source

Embodiment 1

[0077] The embodiment of the present invention provides a face and iris image acquisition method, and the present invention is applicable to a device having two sets of imaging modules of a face lens and an iris lens, and the face lens and the iris lens are installed on the first pan / tilt at the same time, Among them, the field of view of the face lens is relatively large, and the field of view of the iris lens is relatively small. The face lens and the iris lens can simultaneously collect images in real time, and the supplementary light source is installed on the second gimbal.

[0078] The first cloud platform and the second cloud platform can rotate up and down and / or left and right, the present invention does not limit the concrete structure of cloud platform, for example can be the electric two-dimensional cloud platform (can be up and down and left and right rotation) controlled by stepper motor, also It can be a simple rotating shaft (only one-dimensional rotation up and...

Embodiment 2

[0167] The embodiment of the present invention provides a face and iris image acquisition device. The face lens and the iris lens are installed on the first pan / tilt at the same time, and the face lens and the iris lens perform image acquisition in real time at the same time, and the supplementary light source is installed on the second platform. On the cloud platform.

[0168] Such as Figure 6 As shown, the device includes:

[0169] The first rotation module 1 is used to rotate the first pan / tilt, so that the face lens and the iris lens are in the collection position.

[0170] The first acquisition module 2 is configured to simultaneously acquire the first human face image and the first iris image through the face lens and the iris lens under the supplementary light of the supplementary light source to the iris lens.

[0171] The first positioning module 3 is used to perform iris positioning on the first iris image. If the iris is not located, it is judged whether the cond...

Embodiment 3

[0209] The method described in the above-mentioned embodiment 1 provided in this specification can implement business logic through a computer program and record it on a storage medium, and the storage medium can be read and executed by a computer to achieve the effect of the solution described in embodiment 1 of this specification. Therefore, the present invention also provides a computer-readable storage medium for face and iris image acquisition, including a memory for storing processor-executable instructions. When the instructions are executed by the processor, the face and iris images comprising Embodiment 1 are realized. The steps of the acquisition method.

[0210] The present invention utilizes the feature points and light spot data of the overlapping area captured by the face image and the iris image, avoids the iris positioning failure problem caused by the interference of large light spots, and can still accurately determine the iris position when the light spot cov...

Abstract

The invention discloses a face and iris image acquisition method and device, a readable storage medium and equipment, and belongs to the field of biological recognition. The method comprises the following steps: acquiring the area and position of a light spot on an iris image when a face lens and an iris lens are located at a collection position and the iris cannot be positioned in the iris image, performing overlay analysis on the face image and the iris image, judging whether the light spot shields the iris according to similar feature point information of the face image and the iris image, and if the area of the light spot is too large and the iris is shielded, adjusting the angle and the position of the light supplementing light source, so that the light spot avoids the iris area, and then a clear and available iris image can be acquired. According to the method, the problem of iris positioning failure caused by large light spot interference is avoided, the position of the iris can still be accurately judged when the light spot shields the iris, the light spot accurately avoids the iris area by adjusting the angle or the position of the light supplementing light source, and then a clear and available iris image is collected.

Description

technical field [0001] The invention relates to the field of biometric identification, in particular to a face and iris image collection method, device, readable storage medium and equipment. Background technique [0002] Biometrics technology is a combination of computer and high-tech means such as optics, acoustics, biosensors and biostatistics, using the inherent physiological characteristics of the human body (such as fingerprints, faces, irises, etc.) and behavioral characteristics (such as handwriting, voice, etc.) gait, etc.) for personal identification. [0003] As an important identification feature, the iris has the advantages of lifetime uniqueness, stability, collectability, and non-invasiveness. It is an inevitable trend in the development of identification research and application. [0004] The iris is hidden deep inside the eye. During the iris information collection process, quite a number of people wear glasses, which has a certain probability of the lens r...
