Description

Card identification device capable of direct photographing using wide angle lens}

The present invention relates to a card recognition device, in particular, by directly photographing a card without a reflector (MIRROR), there is less distortion due to external light, so the data processing time is shortened. In addition, for miniaturization and simplification, a lens with a wide angle of view is applied to The present invention relates to a card recognition device in which the area can be widened and the focal length is shortened, so that the size of the product can be reliably reduced and the manufacturing cost is reduced.

Recently, various types of cards are generally used. These cards include credit cards for payment, debit cards and identification cards to prove identity, and licenses or qualifications to prove various qualifications.

There are various methods of photographing a card or an ID card in the related art, but the focal length is long and the image is obtained by refracting the image by applying a reflector to obtain a perfect image, but the image is broken and distortion occurs.

As shown in FIG. 2, when the card image is acquired with a general camera lens in a structure without a reflector, the size of the product is very large.

As shown in FIG. 2, if illumination is irradiated in the direction of the camera's angle of view, light is reflected on the card surface, which causes a problem in recognizing the distortion of the final image.

3 shows an example of the internal structure of a conventional photographing apparatus for various cards.

Since the card is directly recognized without a reflector, including a wide-angle lens connected to the camera, a lighting device required for camera shooting, a white film for illumination, and an IR and UV light source sensor for authenticity determination, inside the upper cover It is a structure that minimizes distortion and increases the recognition rate of the card.

The card recognition apparatus according to the present invention can quickly and conveniently take a card by taking a picture of a card such as a credit card or an ID card using a simple structured photographing device.

By using a wide-angle lens with a wide angle of view, the focal length of the camera can be reduced, thereby reducing the size and weight of the product, leading to a reduction in manufacturing cost and providing an economical recognition device.

In addition, the card photographing apparatus according to the present invention does not require a reflector, and the size is minimized, thereby reducing weight.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art can easily implement them. It should be noted that, in the accompanying drawings, the same reference numbers are used as much as possible when indicating the same configuration in other drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known function or a known configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, certain features presented in the drawings are enlarged or reduced or simplified for ease of description, and the drawings and their components are not necessarily drawn to scale. However, those skilled in the art will readily understand these details.

1 is a plan view schematically showing a plan configuration of a card recognition apparatus of the present invention.

Referring to FIG. 1, the card recognition apparatus of the present invention includes a case 100, a circuit unit 110, and a mounting unit 120.

The case 100 has a circuit part 110 therein, and a mounting rack 120a made of a transparent material for mounting the card 130 is provided on one side of the case 100. As shown in FIG. 1, the mounting part 120 arranges a mounting window in the center so as to be within the shooting range of the camera.

When the circuit unit 110 is disposed on the holding window 120a, image data is generated by photographing the fixed card 130. To this end, the circuit unit 110 detects the card 130 when one end of the card 130 is placed on the mounting unit 120, and after a certain period of time, the camera completes the focus correction and photographs to generate an image.

For image acquisition, the circuit unit 110 includes an IR (Infra Red) light source 111-112, a UV (Ultra Violet) light source 113-114, a camera 115, a wide-angle lens 115a, and a first detection sensor 116. ) Can be included. In addition, the circuit unit 110 may include a control unit 140 and a memory.

The IR light sources 111-112 and the UV light sources 113-114 emit infrared and ultraviolet rays, respectively, to verify the card 130.

The camera 115 photographs the surface of the card 130 to generate image data. Here, the camera 115 stores verification information such as a pattern and letters for verification expressed on the photographing surface of the card 130 by infrared and ultraviolet rays supplied by the IR light sources 111-112 and the UV light sources 113-114. I will shoot. To this end, the camera 114 is configured as a device capable of photographing images in the visible, infrared, and ultraviolet regions.

Here, configurations for scanning IR light sources 111-112, UV light sources 113-114, and camera 115 are not limited to the present invention only as it is suggested that the configuration may be changed according to a photographing method.

The wide-angle lens 115a is connected to the camera 115 to obtain a desired image at a close distance, even for an image from a distant place when shooting. Here, in the case of the wide-angle lens 115a, as the edge of the image is rounded, software correction is performed to flatten the image, thereby completing the creation of a straight image as shown in 4 without difficulty in recognition.

The first detection sensor 116 is connected to the control unit by a cable and disposed at one end of the upper case 111 to detect the card, and detects whether the card 130 is inserted into the holding window 120a. In addition, the first detection sensor 116 serves to transmit the detection result to the control unit so that the control unit 140 can control the transfer of the card. The first detection sensor 116 may be composed of a light detection sensor having a light receiving unit and a light emitting unit. That is, the light emitted through the light emitting portion of the first detection sensor 116 is reflected on the card 101 and incident on the light receiving portion, so that the first detection sensor 116 can detect the presence of the card 101.

The control unit 140 detects whether or not the card is mounted according to the detection result of the first detection sensor 116 and controls focus and photographing. Specifically, the control unit checks whether the card 130 is inserted into the mounting unit 120 by the first detection sensor 116. And when the card 130 is seated on the mounting unit 120, the controller 140 controls the IR light source 111-112, the camera 115, and the UV light source 113-114 to control the mounted card 130 You will be shooting. Data generated by photographing is stored in a memory provided in the circuit unit 110.

Although shown and described as a specific example to illustrate the technical idea of the present invention, the present invention is not limited to the same configuration and operation as the specific embodiment as described above, and various modifications are within the scope of the present invention. Can be carried out in Therefore, such modifications should be regarded as belonging to the scope of the present invention, and the scope of the present invention should be determined by the claims to be described later.
