Definitions
- the present disclosure relates to the field of image acquisition technologies, and in particular, to a method, an apparatus, and a red film identification device for acquiring an iris image.
- irises are more and more widely used in the field of personal identification because of their high degree of uniqueness.
- the existing iris collection needs to be realized by the iris collecting instrument, that is, when the user collects the iris, the eye needs to be attached to the iris collecting instrument, so the process needs to be highly matched with the use requirement of the iris collecting instrument, thereby improving the requirement.
- the difficulty of the user is, when the user collects the iris, the eye needs to be attached to the iris collecting instrument, so the process needs to be highly matched with the use requirement of the iris collecting instrument, thereby improving the requirement. The difficulty of the user.
- the part of the eye is photographed to obtain an image containing the part of the eye.
- the center position of the eyeball and the radius of the eyeball in the image are determined by a radial symmetric transformation RST method.
- determining, according to an eyeball position parameter in the image, determining a shooting parameter for capturing an iris comprising: determining a near-infrared shooting parameter for capturing an iris according to an eyeball position parameter in the image;
- the first determining module includes:
- the above method provided by the embodiment of the present disclosure determines a photographing parameter for photographing an iris according to the acquired image including the part of the eye. Since the image including the eye part can be obtained in various ways, for example, by using ordinary visible light shooting mode, in the above method, the user does not need to attach the eye to the prescribed position, and does not need to perform some highly coordinated actions, but only If you need to stand normally, you can take a picture of the user's eye and determine the shooting parameters for shooting the iris. It can be seen that the above method achieves the purpose that the user can accurately acquire the iris image without requiring a high degree of cooperation, thereby improving the user experience.
- the acquisition sub-module 211 is configured to photograph an eye part to obtain an image including an eye part.
- the second determining sub-module 222 can also be configured to determine an eye center position and an eye radius in the image by a radial symmetric transform RST method in the region of the eye.
- an apparatus 900 for acquiring an iris image which may be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, according to an exemplary embodiment. , fitness equipment, personal digital assistants, car mobile terminals, etc.
- Processing component 901 typically controls the overall operation of device 900, such as operations associated with display, telephone calls, data communications, camera operations, and recording operations.
- Processing component 901 can include one or more processors 909 to execute instructions to perform all or part of the steps of the above described methods.
- processing component 901 can include one or more modules to facilitate interaction between component 901 and other components.
- processing component 901 can include a multimedia module to facilitate interaction between multimedia component 904 and processing component 901.
- the I/O interface 902 provides an interface between the processing component 901 and the peripheral interface module, which may be a keyboard, a click wheel, a button, or the like. These buttons may include, but are not limited to, a home button, a volume button, a start button, and a lock button.
