Binocular iris acquisition device and acquisition method

Abstract

The invention provides a binocular iris acquisition device and an acquisition method, the device including a base and a screen, the right end of the base is movably connected with a pedal; the bottomof the pedal is fixedly connected with a pressure block, the left end of the pressure block is movably connected with a first gear, the outer wall of the first gear is movably connected with a rotating shaft, the outer wall of the rotating shaft is movably connected with a belt, the inner wall of the belt is movably connected with a second gear, the left end of the second gear is movably connectedwith a rack, and the left end of the rack is fixedly connected with a lifting rod. The invention discloses a binocular iris acquisition device and an acquisition method. The pedal downwards presses the pressure block; the rack on the left wall of the pressure block starts to move; the rack drives the first gear, the first gear drives the lifting rod, the lifting rod drives the buffer frame and the recognizer to automatically ascend and descend, the movable rod drives the sliding block to move, the sliding block drives the push rod, the push rod drives the first piston and the first piston toextrude hydraulic oil, the hydraulic oil extrudes the second piston and the second piston to push the air bag to spray air, and the air is exhausted from the air outlet and blows away dust.

Description

technical field [0001] The invention relates to the technical field of iris recognition, in particular to a binocular iris collection device and a collection method. Background technique [0002] Iris recognition technology is based on the iris in the eye for identification. It is used in security equipment and places with high confidentiality requirements. With the development of iris recognition technology, iris recognition can be installed in payment terminals, registration terminals and access control terminals. Used on-board, iris recognition appears in people's daily life, and its development prospects will become broader. [0003] In the prior art, the height of most iris recognition machines is fixed and cannot be raised and lowered. When in use, the height of the iris recognizer is too low, and it is necessary to bend down to recognize it. If the height of the iris recognizer is too high, the recognition is difficult.

Problems solved by technology

[0003] In the prior art, the height of most iris recognition machines is fixed and cannot be raised and lowered. When in use, the height of the iris recognizer is too low, and it is necessary to bend down to recognize it. If the height of the iris recognizer is too high, the recognition is difficult. Both affect the user's direct experience, giving the user a bad impression, and when the camera of the iris recognizer recognizes the iris, it will encounter dust on the camera and cannot recognize the iris, which makes the user distrust the iris recognition. Eye iris collection device and collection method came into being
