Description

Simultaneous inspection device for double vision and foreign matter detection for optical system lenses for virtual reality or augmented reality

The present invention relates to an inspection device for an optical system lens, and more specifically, to a device for simultaneously inspecting whether double vision occurs and whether foreign substances are detected for an optical system lens for virtual reality or augmented reality. In other words, the present invention provides an inspection device that can simultaneously perform an inspection to determine whether top/bottom/right/left double vision occurs due to image distortion in the lens of an optical system for virtual reality or augmented reality, and an inspection to determine whether foreign substances larger than a standard size are detected. It is about.

The content described in this part simply provides background information on an embodiment of the present invention and does not constitute prior art.

Double vision is a phenomenon in which one object appears twice or appears double due to a shadow. In particular, in the case of an optical lens, double vision refers to a phenomenon in which light passing through an optical lens is refracted and a portion of an object is imaged twice. In other words, if there is double vision in the lens of the optical system, the light passing through the left and right lenses does not overlap into a single image, so a double image of part of the object is formed.

An optical system refers to a system that appropriately arranges reflectors, lenses, prisms, etc. to create images of objects or transmit light energy using reflection or refraction of light. In particular, an optical system for virtual reality or augmented reality is not an optical system that simply provides light from the real world, but in the case of a virtual reality optical system, it refers to an optical system that provides virtual reality using image light, and in the case of an augmented reality optical system, it refers to an optical system that provides virtual reality using image light. It refers to an optical system that provides augmented reality by combining light and video light.

In the case of such optical systems for virtual reality or augmented reality, they generally provide image light rather than light of the real world. If a problem occurs in lens bonding or a mechanical deviation in the processing or injection process occurs, the user of the optical system in question You may experience double vision, where the images seen through both lenses of the optical system do not overlap into one image. Therefore, when manufacturing an optical system for virtual reality or augmented reality, it is checked in advance whether double vision occurs in the optical system being manufactured, and only when there is no problem is the virtual reality or augmented reality device finally assembled.

Despite these problems, no separate device has been developed to pre-test whether double vision occurs in optical lenses for virtual reality or augmented reality, and in most cases, people wear them to check. I had no choice but to do so. Therefore, there is a need to develop a device that can perform the test without human intervention.

Meanwhile, in the optical system, if there is a foreign substance larger than the standard size in the lens due to manufacturing problems, etc., it can cause great inconvenience to the user of the optical system, so it becomes an important inspection item. In the case of optical systems for virtual reality or augmented reality, there is a difficulty in having to perform both the test for double vision described above and the test for detection of foreign substances. In particular, there is a difficulty in that if one test is performed first, problems may occur in the process of performing the remaining tests. In other words, if the test for double vision occurs first and then the test for foreign material detection is performed, the previously adjusted optical system may be distorted and the test for double vision may become meaningless. Conversely, the test for foreign material detection may be performed first and then When conducting a test for double vision, foreign substances may enter the test during the test.

The above-mentioned background technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention.

The present invention was proposed to solve the above-mentioned problems of the previously proposed methods. The screen of the left lens and the screen of the right lens are respectively photographed using a photographing module for the left lens and a photographing module for the right lens, and then sent to the inspection unit. By transmitting and enlarging each captured screen in the inspection unit to check whether they match each other, double vision is inspected, and at the same time, it is inspected whether foreign substances larger than the standard size are detected in each captured image, thereby creating virtual reality. Or, a device for simultaneously testing whether diplopia occurs and whether foreign substances are detected for an optical system lens for virtual reality or augmented reality, which allows simultaneous inspection of whether double vision occurs in the lens of an augmented reality optical system and whether foreign substances are detected. The purpose is to provide.

In addition, the present invention installs the imaging module for the left lens and the imaging module for the right lens on a rail to which an ultra-precision motor is attached, and uses the ultra-precision motor to precisely control the focus of each imaging module and the lens. By doing so, it is possible to simultaneously inspect with high accuracy whether diplopia occurs and whether foreign substances are detected for the lenses of optical systems for virtual reality or augmented reality, whether double vision occurs and whether foreign substances are detected for optical system lenses for virtual reality or augmented reality. Another purpose is to provide a simultaneous inspection device.

In addition, the present invention further installs a white background displaying a square-shaped test area with an empty center on the rear of the inspection device, then reproduces the image light in the shape of a circle with a black center in the optical system, and then By photographing the image of the left lens and the image of the right lens separately in the imaging department and examining them in the inspection department, it is possible to quickly and easily intuitively check whether diplopia has occurred through the relationship between the circular shape and the test area in the captured image. Another purpose is to provide a device for simultaneously checking whether diplopia occurs and foreign matter is detected for an optical system lens for reality or augmented reality.

Figure 1 is a diagram showing the configuration of a device for simultaneously checking whether double vision occurs and whether foreign substances are detected for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention. As shown in FIG. 1, the simultaneous inspection device 10 for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention includes a main body 100 and an optical system holder. It may be configured to include 200, a photographing unit 300, and an inspection unit 400, and depending on the embodiment, it may further include a rail unit 500 and a white background unit 600.

Figure 2 is a diagram illustrating an example of an implementation of a device for simultaneously checking whether diplopia occurs and whether foreign substances are detected for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention. Hereinafter, with reference to FIGS. 1 and 2, each configuration of the simultaneous inspection device 10 for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention will be described in detail. Let me explain.

The main body 100 has a frame structure of an inspection device for an optical system lens, and an optical system holder 200 on which an optical system lens and a board are mounted may be installed on one side. That is, the main body 100 mounts the optical system lens and board to be inspected through the optical system holder 200 and fixes its position, thereby allowing inspection of the optical system lens through the imaging unit 300 and inspection unit 400, which will be described later. Ensure that it is carried out smoothly. Depending on the embodiment, the photographing unit 300 may be used attached to the main body through the rail unit 500, which will be described later, but is not limited to this configuration. Additionally, depending on the embodiment, the inspection unit 400, which will be described later, may be implemented in part or inside the main body 100, but is not limited to this configuration.

More specifically, as shown in FIG. 2, the main body 100 combines four rectangular-shaped frames: an upper frame 110, a lower frame 120, a left frame 130, and a right frame 140. It may be in a pre-ordered form. However, the configuration is not limited to this form, as long as it is possible to achieve the purpose of simultaneously inspecting whether diplopia occurs and whether foreign substances are detected by mounting the optical system lens and board to be inspected through the optical system holder 200 installed on one side. It may be implemented in any form. When implemented in the configuration shown in FIG. 2, the upper frame 110 and lower frame 120 may be implemented with a light and hard metal material including aluminum, and the left frame 130 and right frame 140 It can be implemented as a plastic material containing bakelite, which has excellent electrical insulation, mechanical strength, and heat resistance. This is to maintain the shape and position stably even when the heavy optical system lens and optical system board are mounted on the optical system holder 200 so as not to reduce the accuracy of inspection, but the configuration of the main body is not limited to using the corresponding material. Here, bakelite is a thermosetting resin produced by the reaction of phenol and formaldehyde (actually formalin, its aqueous solution, is used), and has excellent electrical insulation, mechanical strength, and heat resistance.

As shown in FIG. 2, the optical system holder 200, which will be described later, may be installed on the upper frame 110 so that the optical system to be inspected can be stably mounted. However, the configuration is not limited to that location. In other words, the optical system holder 200 is a part and installation method of the main body 100, as long as the optical system to be inspected is maintained in a stable state and the inspection for double vision and detection of foreign substances can be performed simultaneously. etc. can be implemented in any way.

The optical system holder 200 serves to stably mount the optical system to be inspected so that the inspection can proceed. In the present invention, the optical system to be inspected particularly refers to an optical system for virtual reality or augmented reality. Therefore, the optical system to be inspected in the present invention includes not only the optical system lens on which the actual inspection must be performed, but also an optical system board that reproduces the image and transmits it to the optical system lens so that image light can be output to the optical system lens. Therefore, the optical system holder 200 must be able to mount not only the optical system lens but also the optical system board. Figure 4 is a diagram showing the detailed configuration of the optical system holder in the simultaneous inspection device for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention. As shown in FIG. 4, the optical system holder 200 of the simultaneous inspection device for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention is where the optical system lens is mounted. It may be configured to include an optical system lens mounting module 210, and an optical system board mounting module 220 on which an optical system board that reproduces the image and transmits it to the optical system lens so that image light can be output to the optical system lens is mounted. At this time, as shown in FIG. 2, the main body 100 includes an empty space, so that when the optical system lens is mounted on the optical system lens mounting module 210, the field of view of the optical system lens is secured through the empty space. You can.

The photographing unit 300 functions to capture lens images for each of the left and right lenses of the optical system mounted on the optical system mounting unit 200 and transmits them to the inspection unit 400, which will be described later. In the present invention, the test for occurrence of double vision is performed by checking whether the image seen through the left lens and the image seen through the right lens match as one image, so the inspection unit captures the lens image for each of the left and right lenses of the optical system. You need to send it to . In addition, since the foreign matter detection test must be performed on each of the left and right lenses of the optical system, it is also necessary to photograph the lens images for each of the left and right lenses of the optical system and transmit them to the inspection unit.

Figure 5 is a diagram illustrating the detailed configuration of a photographing unit in a simultaneous inspection device for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention. As shown in FIG. 5, the imaging unit 300 of the simultaneous inspection device 10 for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention is mounted on an optical system. An imaging module 310 for the left lens to capture the image of the lens for the left lens of the optical system mounted on the unit 200, and to photograph the image of the lens for the right lens of the optical system mounted on the optical system holder 200 The image of the lens for the left lens and the image of the lens for the right lens captured by the photographing module 320 for the right lens, the photographing module 310 for the left lens, and the photographing module 320 for the right lens, respectively, will be described later. It may be configured to include a transmission module 330 that transmits to the inspection unit 400. At this time, the photographing module 310 for the left lens and the photographing module 320 for the right lens each have a zoom function and can be effectively used for photographing and comparing captured images.

As described above, in the present invention, the test for double vision is performed by checking whether the image viewed through the left lens and the image viewed through the right lens match as one image, so the transmission module 330 captures the images at the same time. Depending on the embodiment, time information is transmitted together when transmitting the image information so that the image of the lens for the left lens and the image of the lens for the right lens can be compared, or images of a pair of lenses taken at the same time are transmitted together. You can also bundle them together and send them.

Here, the transmission method of the transmission module 330 can be both wired and wireless. That is, the transmission method used by the transmission module 330 is not only a transmission method through a physical connection such as a cable, but also a local area network (LAN), a wide area network (WAN), or a value-added network (Value Area Network). Wired networks such as Added Network (VAN), mobile radio communication network, satellite communication network, Bluetooth, Wibro (Wireless Broadband Internet), HSDPA (High Speed Downlink Packet Access), LTE (Long Term Evolution), It can be implemented with all types of wireless networks, such as 3/4/5/6G (3/4/5/6th Generation Mobile Telecommunication).

The photographing unit 300 must capture images of the lenses for each of the left and right lenses of the optical system mounted on the optical system holder 200 using the photographing module 310 for the left lens and the photographing module 320 for the right lens. Therefore, the imaging module 310 for the left lens and the imaging module 320 for the right lens can be installed at a distance (for example, 15 to 30 cm away) where the image of the lens can be captured well for each of the left and right lenses of the optical system. there is. The installation method is not particularly limited, and as an example, it may be installed using a separate stand (not shown), but preferably, as shown in FIG. 2, using a rail unit 500 to be described later. Can be installed. That is, as shown in FIG. 2, the imaging unit 300 of the simultaneous inspection device 10 for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention is connected to the main body. It is advantageous to install it on the rail unit 500 installed in . This means that the distance between the left lens and the right lens may be different for each optical system to be inspected, and accordingly, there is a need to adjust the installation positions of the imaging module 310 for the left lens and the imaging module 320 for the right lens. This is because it can be particularly advantageous in terms of being able to effectively respond to needs.

The rail unit 500 may be further installed on one side of the main body 100, and when the rail unit 500 is installed, the photographing unit 300 is installed on the rail unit 500 and moves along the rail. It can be implemented so that it can be fixed in a desired location. A more detailed configuration of the rail unit 500 will be described below with reference to FIG. 6.

Figure 6 is a diagram showing the detailed configuration of the rail portion in the simultaneous inspection device for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention. As shown in FIG. 6, the rail unit 500 of the simultaneous inspection device 10 for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention is a rail ( 510) and an ultra-precision motor 520. Here, the rail 510 serves to allow the photographing modules 310 and 320 to be placed on it, moved, and fixed to a desired position. As shown in FIG. 2, the left frame of the main body 100 It connects between 130 and the right frame 140, and may be installed on the side where the optical system lens mounting module 210 of the optical system mounting part 200 is located. However, the shape of the rail 510 is not limited to a specific shape, or the installation location is not limited to a specific location.

Meanwhile, the rail unit 500 may further include an ultra-precision motor 520, which operates the optical system lens mounted on the optical system lens mounting module 210 of the optical system mounting unit 200 and each of the photographing unit 300. It serves to precisely control the focus between the shooting modules 310 and 320. That is, if the focus between the optical system lens and the photographing modules 310 and 320 is not fine, the position of the photographing modules 310 and 320 is precisely adjusted using the ultra-precision motor 520 to achieve accurate focus. can do.

The inspection unit 400 receives the lens image for the left lens and the lens image for the right lens, respectively captured by the photographing unit 300, and simultaneously inspects whether double vision occurs and whether foreign substances are detected. As previously explained, in the case of optical lenses for virtual reality or augmented reality, both an inspection for double vision and an inspection for detection of foreign substances must be performed. In particular, the inspection must be performed simultaneously to prevent the occurrence of additional problems. The inspection unit 400 of the simultaneous inspection device 10 for double vision and detection of foreign substances for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention performs a test for double vision and detection of foreign substances. It is configured to simultaneously perform the inspection of the inspection unit 400. Hereinafter, the detailed configuration and role of the inspection unit 400 will be described in more detail with reference to FIG. 7.

FIG. 7 is a diagram illustrating the detailed configuration of an inspection unit in a simultaneous inspection device for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention. As shown in FIG. 7, the inspection unit 400 of the simultaneous inspection device 10 for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention is, A first inspection module 410 that checks whether double vision occurs by enlarging the lens image for the left lens and the lens image for the right lens received from the imaging unit 300 and then comparing them to see if they match each other; And a second inspection module ( 420). In particular, the first inspection module 410 and the second inspection module 420 simultaneously inspect the lens image for the left lens and the lens image for the right lens at the same viewpoint received from the photographing unit 300. It can be done. As described above, the transmission module 330 may transmit time information together when transmitting captured image information, or may bundle and transmit images of a pair of lenses taken at the same time, and may transmit the first image of the inspection unit 400. Using this, the inspection module 410 and the second inspection module 420 can simultaneously perform inspection on the lens image for the left lens and the lens image for the right lens at the same viewpoint received from the photographing unit 300. It becomes possible.

The first inspection module 410 checks whether diplopia occurs by comparing whether the lens image for the left lens and the lens image for the right lens received from the photographing unit 300 match each other. Comparisons can be made more easily by magnifying and comparing rather than directly comparing. Of course, when magnifying, the magnification ratio must be the same for the lens image for the left lens and the lens image for the right lens. Depending on the embodiment, the first inspection module 410 may display the comparison result by comparing the image of the lens for the left lens and the image of the lens for the right lens using a software program and displaying a coincidence rate. Additionally, the images of the two lenses can be displayed in an overlapping manner so that the administrator managing the inspection can visually confirm them. Depending on the embodiment, a white background portion 600 may be additionally included to make comparison inspection more intuitive, faster, and easier, which will be described in detail with reference to FIGS. 8 and 9.

Figure 8 shows an implementation example (a) of a white background portion in a device for simultaneously inspecting whether diplopia occurs and foreign matter is detected for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention, and in this case, the white background portion to be reproduced in the optical system lens. This diagram shows an example (b) of circular image light. As shown in (a) of FIG. 8, the white background part 600 is a component in which a rectangular test area with an empty center is displayed on a white background. Depending on the embodiment, the white background part 600 is located on the back of the main body, that is, the optical system lens mounting module. It can be installed to be detachable from the main body 100 at a location opposite to where 210 is installed. At this time, by reproducing the image light in the shape of a circle with a black center as shown in (b) of FIG. 8 in the optical system mounted on the optical system holder 200, the first inspection module 410 of the inspection unit 400 performs imaging. Through the relationship between the circle shape and the test area in the image, it is possible to quickly and easily intuitively check whether diplopia has occurred.

FIG. 9 shows a non-defective product that appears when inspecting whether double vision occurs in the inspection unit when the configuration of FIG. 8 is applied in a simultaneous inspection device for double vision and foreign matter detection for an optical system lens for virtual reality or augmented reality according to an embodiment of the present invention. This drawing shows examples of (a) and defective products (b, c). The first inspection module 410 of the inspection unit 400 can intuitively and quickly and easily perform an inspection for double vision based only on the relationship between the circular shape and the test area in the captured image as shown in FIG. 9.

The second inspection module inspects whether foreign substances larger than a predetermined size are detected through built-in software for each of the lens images for the left lens and the lens image for the right lens transmitted from the photographing unit 300. , for example, if the size of the foreign matter is 5㎛ or larger, it can be judged as defective.

In the inspection unit 400, only when the first inspection module 410 produces a result that double vision has not occurred and at the same time, the second inspection module 420 produces a result that no foreign matter has been detected, the corresponding virtual reality or augmented reality The optical system lens can be judged as a good product. If even one of the test results of the first inspection module 410 or the second inspection module 420 is defective, the optical system lens for virtual reality or augmented reality is determined to be defective.

As described above, according to the simultaneous inspection device for double vision and detection of foreign substances for an optical system lens for virtual reality or augmented reality proposed in the present invention, the left lens using an imaging module for the left lens and an imaging module for the right lens.
