Description
Technical field
The utility model relates to imaging device technology, particularly relates to a kind of technology of pitching type binocular iris image acquiring device.
Background technology
Existing iris image acquiring equipment all adopts fixed installation pattern, according to a certain angle hanging on wall or put on the table, the user of different height cannot be adapted to, cause the experience of user very poor, the used time gathering iris image is very long, and the quality of iris image is also lower.
In addition, the mentality of designing that existing iris image acquiring equipment mainly adopts is monocular iris capturing, i.e. each iris image gathering eyes, or by arranged side by side for two single iris collecting devices, a support is adopted to transversely link, as easy binocular iris capturing equipment use, but the problem brought thus is imaging, illumination, feedback, control, even power supply unit be all right and left eyes independently, cause the integration of equipment very poor, complex structure, volume is larger, and right and left eyes gathers asynchronous, be easy to cause iris image quality to decline, affect collecting efficiency and identify accuracy.
Utility model content
For the defect existed in above-mentioned prior art, it is high that technical problem to be solved in the utility model is to provide a kind of collecting efficiency, and the pitching type binocular iris image acquiring device that the iris image quality gathered is high.
In order to solve the problems of the technologies described above, a kind of pitching type binocular iris image acquiring device provided by the utility model, comprise base, casing, it is characterized in that: described casing is equipped with infrared distance measurement module, and for showing the range finding pilot lamp of range measurement, the each camera in left and right, each one group of infrared transmitter in left and right;
The left and right sides being laid in infrared distance measurement module that two groups of infrared transmitters and two cameras are symmetrical respectively, casing is equipped with transmissive infrared light and the filter of energy reflect visible light, described filter covers in the detection head of infrared distance measurement module and the camera lens of two cameras.
Further, described base is equipped with rotating rotating shaft, described casing is fixed in rotating shaft, the left and right sides shell wall of casing is respectively fixed with a positioning magnet, the outside of casing is provided with each shell outer magnet around, these two shell outer magnets are all fixed on and land on thing, and these two shell outer magnets all coordinate with casing activity;
Left side shell outer magnet and left positioning magnet about just right, and the shell outer magnet in left side is contrary with the opposite end polarity of left positioning magnet, just right about the shell outer magnet on right side and right positioning magnet, and the shell outer magnet on right side is contrary with the opposite end polarity of right positioning magnet.
Further, the rotary damper for providing damping due to rotation for the rotation of rotating shaft described base is equipped with.
Further, the weight member for balancing both sides weight before and after rotating shaft described rotating shaft is equipped with.
The pitching type binocular iris image acquiring device that the utility model provides, the imaging gathered needed for iris of both eyes image, illumination, mutual, pitching unit are become one, the high-quality iris of both eyes image of energy Quick Acquisition, there is collecting efficiency high, and the feature that the iris image quality gathered is high.
Accompanying drawing explanation
Fig. 1 is the front view of the pitching type binocular iris image acquiring device of the utility model embodiment;
Fig. 2 is the rear perspective view of the pitching type binocular iris image acquiring device of the utility model embodiment;
Fig. 3 is the use-pattern schematic diagram of the pitching type binocular iris image acquiring device of the utility model embodiment.
Embodiment
Illustrate below in conjunction with accompanying drawing and embodiment of the present utility model is described in further detail; but the present embodiment is not limited to the utility model; every employing analog structure of the present utility model and similar change thereof; protection domain of the present utility model all should be listed in, the pause mark in the utility model all represent and relation.
As Figure 1-Figure 2, a kind of pitching type binocular iris image acquiring device that the utility model embodiment provides, comprise base 2, casing 1, it is characterized in that: described casing 1 is equipped with infrared distance measurement module 4, and for showing the range finding pilot lamp 6 of range measurement, the each camera 3 in left and right, each one group of infrared transmitter 5 in left and right;
The left and right sides being laid in infrared distance measurement module 4 that two groups of infrared transmitters 5 and two cameras 3 are symmetrical respectively, casing 1 is equipped with transmissive infrared light and the filter of energy reflect visible light, described filter covers in the detection head of infrared distance measurement module and the camera lens of two cameras;
Described base 2 is equipped with rotating rotating shaft 10, described casing 1 is fixed in rotating shaft 10, the left and right sides shell wall of casing 1 is respectively fixed with a positioning magnet 8, the outside of casing 1 is provided with each shell outer magnet (not shown) around, these two shell outer magnets are all fixed on and land on thing, and these two shell outer magnets all coordinate with casing 1 activity;
Left side shell outer magnet and left positioning magnet about just right, and the shell outer magnet in left side is contrary with the opposite end polarity of left positioning magnet, just right about the shell outer magnet on right side and right positioning magnet, and the shell outer magnet on right side is contrary with the opposite end polarity of right positioning magnet.
In the utility model embodiment, described base 2 is equipped with the rotary damper 7 for providing damping due to rotation for the rotation of rotating shaft 10, makes casing have level and smooth feel when pitch rotation.
The weight member 9 for balancing both sides weight before and after rotating shaft described rotating shaft 10 is equipped with in the utility model embodiment.
The utility model embodiment is applicable to gather iris image, and its using method is as follows:
As shown in Figure 3, base 2 and two shell outer magnets are separately fixed at and land (such as body of wall) on thing 13, user station (or seat) is in device front, and the luffing angle of casing is adjusted by the mode (making casing rotate up and down) above lifting or press down casing 1, make the camera lens of two cameras just to user's eye;
After the adjustment of casing luffing angle, under the damping action of rotary damper and the magnetic attraction effect of shell outer magnet and positioning magnet, the luffing angle of casing can be located, now, the infrared light reflection that left side infrared transmitter is launched by the left eye of user is to infrared distance measurement module and left camera, the infrared light reflection that right side infrared transmitter is then launched by the right eye of user is to infrared distance measurement module and right camera, according to the infrared reflectance signal received, infrared distance measurement module detects whether user is in normal detecting distance, and pass through the in good time prompting user of range finding pilot lamp, if user is in normal detecting distance, two cameras gather the iris image of user's eyes immediately, for the user 11 that height is higher, casing 1 can be faced upward, for the user 12 that height is lower, can by casing nutation.
