Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] Such as figure 1 As shown, according to the embodiment of the present invention, the swiping type fingerprint collection device includes a swiping sensor 10, and the swiping type fingerprint collection device also includes an auxiliary mechanism, the auxiliary mechanism includes a guide part and a pressure control part 40, and the guide part is along the The collection direction of the scratch sensor 10 is set outside the scratch sensor 10 and limits the movement track of the finger; the pressure control part 40 is set in the guide part and controls the pressing force required by the finger to drive the guide part to move. The guide part can control the movement trajectory of the finger, so a...

Abstract

The invention provides a scratching type fingerprint acquisition device. The scratching type fingerprint acquisition device comprises a scratching type sensor (10), and further comprises an auxiliary mechanism, wherein the auxiliary mechanism comprises a guiding portion and a pressure control portion (40), the guiding portion is arranged outside the scratching type sensor (10) in the acquisition direction of the scratching type sensor (10) in an extended mode and limits a moving track of a finger; the pressure control portion (40) is arranged in the guiding portion and controls pressure needed when the finger drives the guiding portion to move. The scratching type fingerprint acquisition device limits the moving track and pressure force of the finger through the auxiliary mechanism, can eliminate interference in acquisition quality due to different users, and improves accuracy and definition of collected fingerprints.

Description

technical field [0001] The invention relates to the field of fingerprint collection equipment, in particular to a scratch-type fingerprint collection device. Background technique [0002] When the fingerprint reader using the wipe sensor is collecting fingerprints, the user needs to move the finger from top to bottom on the wipe sensor, and gradually let each part of the finger touch the wipe sensor, and then the program will splice the collected images into a picture. Complete image to realize the collection and identification of fingerprints. In this process, due to the differences in the position, strength, speed and movement trajectory of the user's fingers, the quality of the final spliced ​​fingerprint image is poor, the image is unstable, and it is not suitable to synthesize the image. In order to improve the image quality of the scratch-and-swipe fingerprint collection device, there is an urgent need for a stable and clear scratch-and-swipe fingerprint collector. ...
