Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference numerals whenever possible, even if they are shown in different drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the embodiments of the present invention. In addition, embodiments of the present invention will be described below, but the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "indirectly connected" . Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise. In describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) can be used.

Fig. 1 shows a near focus which is provided in both eyes of a person to be measured when a person to be measured looks at a target placed at a short distance.

1, when the subject to be measured is located close to the target object 10 disposed close to the subject, the pupil 20 of the subject to be measured, that is, the pupil distance of the eyes 20 is the target object 10 Called "pupil migration phenomenon" occurs while converging toward the near focus (30). Such a pupil dilation is a phenomenon that occurs when a person to be measured is looking at an object placed at a close distance, for example, about 1 to 5 meters (m), when reading or looking at an object held by the person. It does not occur if you are looking at something normally, that is, usually located remotely, or you do not have anything specifically looking at it. Therefore, in the production of the spectacle lens of the person to be measured, the first thing to be considered is that the gaze passes from both eyes in the normal state of the measurement subject, that is, in the state of looking at the distant or infinite distance in a state in which the above- The lens area is grasped.

However, in order to provide a distant or infinite distance focus to a measurement subject, it is necessary to arrange a target object at a position far from the measurement target, so that there is a restriction of a measurement site, a problem of using a large-sized device, As described above, when the target object is used, accurate measurement can not be performed because a pupil deviation occurs in both eyes of the measurement subject.

In order to solve the above-mentioned problems, the present inventor intends to provide an infinite distance focus using a target light source and an infinite focus lens to give an effect to an object to be measured, such as looking at a target object placed at a long distance or an infinite distance. In the present specification, a distance of about 1 meter (m), specifically, about 50 centimeters (cm) from the measurement subject is collectively referred to as "near ", and a distance longer than this distance, ) Is referred to as "infinite distance ", but the scope of protection of the present invention is not limited by the generic term of such a distance concept.

Fig. 2 shows a parameter measuring apparatus necessary for producing a spectacle lens according to an embodiment of the present invention.

Referring to FIG. 2, a parameter measuring apparatus 100 necessary for spectacle lens production may include a distance parameter measuring apparatus 200 and a user terminal 300.

The distance parameter measuring apparatus 200 can provide an infinite distance focus to the measurement object through the infinite focus lens and can photograph the measurement subject looking at the infinite distance focus.

The user terminal 300 can control the operation of the remote parameter measurement device 200 while communicating with the remote parameter measurement device 200. [ Also, the user terminal 300 can receive the image of the measurement subject photographed by the remote parameter measurement device 200 and provide it to the user. In addition, the user terminal 300 can provide the nearest focus to the measurement subject, capture the measurement subject looking at the near focus, and provide the captured image to the user.

According to the embodiment, the parameter measurement device 100 necessary for spectacle lens production may further include a measurement jig (see 400 in Fig. 7). The measurement jig is worn by the person to be measured and can provide a parameter measurement reference for the person to be measured at the time of photographing by at least one of the remote parameter measurement device 200 and the user terminal 300. [

Thus, the present invention provides a method and apparatus for producing a spectacle lens by photographing a subject to be measured for both a long distance and a short distance through a distance parameter measurement apparatus 200 providing an infinite distance focus and a user terminal 300 providing a near focus The necessary parameters can be measured. Particularly, the operation of the remote parameter measurement device 200 is controlled by the user terminal 300, and all measurement results are gathered around the user terminal 300, so that all measurement operations can be performed only by the user terminal 300 It is possible to provide user convenience.

3 shows a functional block diagram of a distance parameter measurement device according to an embodiment of the present invention.

The infinite distance optical portion 210 may include a target light source 212 and an infinite focus lens 214 disposed at the front end of the target light source 212. The infinite distance optical portion 210 may provide an infinite distance focus from the target light source 212 through the infinite focus lens 214 to both sides of the measurement subject. The target light source 212 may be any of a variety of means or modules for providing light and may be a light emitting diode (LED) light emitting device, specifically a flash light emitting diode device, an infrared (IR) . Further, the infinite focus lens 214 may be formed by using a concave lens, a convex lens, or a composite lens in which concave and convex lenses are combined, or other optical path changing means or module capable of providing an infinite distance focus in both directions And can be implemented variously within the range of known technology.

In this regard, Fig. 4 shows the usage principle of the infinite distance optical part 210. Fig. 4, when the target light source 212 in which the binocular 20 of the measurement subject is located at a short distance is viewed through the infinity focusing lens 214, the infinity distance focus 216 is detected by the binocular 20 of the measurement subject. As shown in FIG. More specifically, the target light source 212 is disposed at an arbitrary position, and the infinite focus lens 214 is disposed at a certain distance from the target light source 212 in the direction toward the subject's eye 20, When the light passing through the infinity focusing lens 214 is provided to the measurement object from the light source 212, the infinity distance focus 216 is formed on the eyes 20 of the measurement subject. That is, the target light source 212 disposed at a close distance appears as an object disposed at an infinite distance in the binocular 20 of the measurement subject. As a result, although the target light source 212 is disposed close to the target light source 212, the object to be measured, which substantially looks at the target light source 212, is in a state of looking at an infinite distance, And a normal binocular pupil state as usual is maintained.

The light reflection point is defined as the distance from the subject's face to the camera unit 220, such as the Infinite Distance Binocular Pupil Distance, the Infinite Distance Monocular Pupil Distance, It can be a reference point. The light emitting unit 230 may be variously implemented to perform the function, but it may preferably be a light emitting diode (LED) light emitting device, specifically a flash light emitting diode device, an infrared (IR) . Also, according to the embodiment, the light emitting unit 230 may be a built-in type of the camera unit 220 or an external type separate from the camera unit 220.

The communication unit 240 can communicate with the user terminal 300. The communication unit 240 may receive various signals from the user terminal 300 to control operations of the camera unit 220, the light emitting unit 230, and the like. According to the signal, the light emitting portion 230 provides the flash, the camera portion 220 performs the shooting, or the body portion can move relative to the stand portion, as will be described in more detail below. In addition, the communication unit 240 may transmit the image of the measurement subject photographed by the camera unit 220 to the user terminal 300. The communication unit 240 may be a LAN, a Wideband Code Division Multiple Access (WCDMA), a Long Term Evolution (LTE), a Wireless Broadband Internet (WiBro), a Radio Frequency (RF) , Wireless Fidelity (NFC), Near Field Communication (NFC), Bluetooth, and infrared communication.

According to the distance parameter measuring apparatus 200 as described above, the apparatus 200 is disposed on the front face of both eyes of the person to be measured, and the light is supplied from the target light source 212 so that the light passes through the infinite focus lens 214 The person to be measured will see the infinite distance focus without pupil leaning. Thereafter, when the measurement target person looking at the infinite distance focus is photographed using the camera unit 220, a shot image relating to the face of the measurement target person can be obtained, and based on this, can do.

Fig. 5 shows an appearance of a distance parameter measurement apparatus according to an embodiment of the present invention.

The body unit 250 may include the infinite distance optical unit 210, the camera unit 220, the light emitting unit 230, and the communication unit 240 shown in FIG. The stand portion 260 is formed to extend in a direction perpendicular to the paper surface, and the body portion 250 can be coupled.

The body portion 250 is vertically movably coupled to the stand portion 260, so that it can move appropriately according to the body of the measurement subject, the photographing environment, and the like. In particular, such movement by the body portion 250 may be based on user input received via the user terminal 300. That is, when the user inputs an instruction regarding up-and-down movement of the main body unit 250 through the user terminal 300, it is transmitted to the remote parameter measuring apparatus 200, and the main body unit 250 is moved to the stand- As shown in FIG.
