Embodiment Construction

[0032] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference symbols are used in the drawings and descriptions to refer to the same or like parts.

[0033] figure 1 is a schematic diagram of sensing fingerprints drawn according to known techniques, and figure 2 is a schematic diagram of fingerprint sensing according to an exemplary embodiment of the present disclosure.

[0034] Please refer to figure 1 and figure 2 In the example where the user identification function is implemented on devices such as tablet computers and interactive video walls, a sensor is arranged under the display screen to sense the user's fingerprint. As mentioned above, to be able to identify fingerprints, the captured image needs to have sufficient resolution, and the detection range of the sensor with sufficient density can completely cover the object to be ...

Abstract

The invention provides a fingerprint recognition method. The method includes obtaining a plurality of fingerprint images by sensing a finger of a user, respectively calculating geometric center points corresponding to the fingerprint images, and calculating positions and offsets of the fingerprint images according to the geometric center points. The method also includes filling signals in the fingerprint images into a part of pixels in a pixel array according to the positions and the offsets of the fingerprint images, and obtaining signals of other pixels in the pixel array by inputting the signals filled in the part of pixels in the pixel array into an artificial intelligence engine. The method further includes generating a candidate fingerprint image and recognizing a user based on the candidate fingerprint image.

Description

technical field [0001] The invention relates to a fingerprint identification method and an electronic interactive device. Background technique [0002] With the rapid development of touch display and identification technology, quite a lot of applications have been derived. For example, after identifying the operator of the touch display, personalized interfaces and information can be provided on the touch screen. [0003] At present, a touch display equipped with a fingerprint capture device has been developed, which can identify the user when the user uses the touch screen and provide personalized interaction. Generally speaking, to be able to identify fingerprints, the captured image must be of high resolution, for example at least 500dpi˜1200dpi. However, in some application fields, high-resolution fingerprint images cannot be captured. For example, transparent displays cannot configure sensors at such a high density considering the transmittance. Therefore, how to id...
