[0001] The present invention relates to a 3D stereoscopic imaging system and a real-

The present invention relates to a stereoscopic image system and a real-time observation system using a monocular camera that implements a three-dimensional image system using one camera and one transparent sectional plate, and more particularly, The control unit (MCU) controls the rotation angle of the transparent plate and the control of the image acquisition through the camera, and the control of the active shutter type three-dimensional glasses. The present invention relates to a stereoscopic image system and a real-time observation system using a monocular camera, which allows a user to observe a three-dimensional image output by a computer or a projector in real time by wearing the three-dimensional glasses.

In general, as shown in Fig. 1, the distance between the human pupils is constant (60-65 mm). When a person looks at an object, a visual angle is generated between the eyes and the object. The depth of the three-dimensional image varies. By adjusting this angle, the depth of the three-dimensional image can be adjusted and accurate time information can be provided.

Conventionally, two cameras are used to implement a three-dimensional image. In this case, the characteristics of images acquired from two different cameras are different from each other, and when acquiring a three-dimensional image therefrom, an error occurs in the image, which causes an observer to experience visual fatigue in the three-dimensional image observation. It also costs a lot because it uses two different cameras.

When a single camera is used to acquire a three-dimensional image, the characteristics of acquired images are the same, so that when three-dimensional images are acquired, visual fatigue is eliminated.

As a conventional technique, Korean Patent Laid-Open No. 10-2007-0088876 relates to a stereoscopic moving image photographing apparatus for photographing a stereoscopic moving image of a nearby object. In order to photograph a stereoscopic moving image of a nearby object, In the circular transparent plate, a part of the outer portion of the transparent plate forms an empty space, and a portion of the outer portion of the transparent plate, which is not an empty space, is a refracting portion. When the transparent plate is rotated by the rotation of the rotating means to block the refracting portion around the optical axis of the camera lens group, the incident image is refracted according to the refractive index of the refracting portion. When the passing portion is located on the optical axis of the camera lens group, Without passing through. Therefore, it is possible to obtain two images such as a refracted image and a non-refracted image by periodic rotation of the transparent plate, and a three-dimensional image is produced from these two different images.

That is, in the case of the Korean Patent Laid-Open No. 10-2007-0088876, when the image is obtained through the transparent plate, the characteristics (focal distance) of the image changes due to the change of the refractive index. On the other hand, In case of acquisition, the characteristics (focal distance) of the image are not changed. Thus, when two-dimensional images having different image characteristics are used to produce a three-dimensional image, the viewer feels visual fatigue.

Therefore, a three-dimensional image system which does not deteriorate performance compared with a conventional three-dimensional image system using two cameras can be demanded, in which a single camera is used but there is no visual fatigue and a three-dimensional image can be observed in real- do

Hereinafter, a stereoscopic image system and a real-time observation system using a monocular camera according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic view for explaining a feature of image information obtained by using a transparent plate.

2 (a) shows a case in which a transparent bifurcation plate (TRD in Fig. 2) (that is, a transparent plate) is fixed vertically when observing an object, and there is no change in observation time of the object. 2B shows a case in which the transparent plate (TRD in FIG. 2) (that is, the transparent plate) is inclined at a certain angle, and the viewing point of the image is moved in parallel in proportion to the angle. In addition, the viewing point of the object moves in parallel to the left and right sides in accordance with the rotational direction of the transparent disc.

In the present invention, an active shutter glass module is provided to implement a three-dimensional image using left and right images, that is, a total of two images, using the transparent die plate 150, And the right image (right eye image) are sequentially observed by the camera, so that the active shutter glass module is controlled to observe a desired image with a human eye.

3 is a schematic view for explaining the overall configuration of a stereoscopic image system and a real-time observation system using a monocular camera according to an embodiment of the present invention. The stereoscopic image system includes a transparent plate 150, a motor unit 180, a camera unit 190, a control unit 200, an image output unit 260, and an active shutter type eyeglass unit 300.

The transparent plate 150 has a transparent plate and is rotated by the motor unit 180 at a predetermined angle and period so that the image of the left eye (left image) and the image of the right eye (right image) (190). The transparent plate 150 is disposed between the object 110 and the camera unit 190 so as to be close to the lens 192 of the camera unit 190 and the object 110 to be imaged.

That is, when the transparent plate 150 is rotated to the left with respect to the optical axis, a left-eye image (left-side image) obtained as an image obtained by moving the image acquisition point in parallel to the left when the object is acquired is acquired (Right image), which is the result of acquiring the image by moving the image acquisition point in parallel to the right when acquiring the image of the object, when the transparent plate 150 is rotated to the right.

The transparent sieve plate 150 may be made of a cylindrical BK7 material, and the characteristics of the three-dimensional image may vary depending on the material and thickness of the transparent sieve plate 150. [ The transparency plate 150 periodically rotates, and observation characteristics through the image output unit 260 such as a computer monitor are changed according to the rotation speed.

It is noted that the transparent baffle plate 150 used in the present invention can make a difference in images using not only BK7 material but also different materials, different kinds of materials and different thicknesses of different refractive indexes of different objects.

When the transparent plate 150 is formed of a material having a different refractive index, the difference between the acquired left and right images can be increased according to the refractive index of the material used in the transparent plate 150. For example, the transparent baffle plate 150 can be formed by joining two materials having different refractive indices.

If the same material is used, the difference between the left and right images increases in proportion to the rotation angle. However, in the case of the same rotation angle, the difference between the right and left images may be larger as the refractive index of the constituent material is larger. Glass, plastic, etc. have their own refractive indices.

The left and right images acquired are calculated according to Snell's Law. When light passes through a specific medium, light refracts (that is, when light enters the medium from the air) The refraction phenomenon (that is, the light is emitted from the medium into the air) occurs, and the refraction of the image due to the two refractions causes a difference in the obtained left and right images.

Table 1 shows an example of materials usable for the transparent baffle plate 150 of the present invention and the refractive index thereof.

The transparent plate is made of BK7 (crown glass borosilicate), Fused Silica, Barium fluoride, Carbon, Diamond, FUSED GERMANIA, Potassium bromide, Sodium chloride Sodium chloride, Zinc Selenide, Germanium, Aluminum arsenide, Calcium fluoride, Magnesium fluoride, Optical glass (SF11, SF10, SF5), And may include at least one material selected from the group consisting of sapphire, zinc sulfide, AMTIR-3, and crystalline silicon.

The motor unit 180 includes a motor and a motor driving unit.

The motor is a motor that rotates the transparent mold plate 150 at a predetermined angle and period. The rotation axis of the motor is connected to the bottom surface of the mold plate 150 in which the transparent mold plate 150 is inserted, and is driven by the motor drive unit . A stepping motor can be used as the motor, and the motor can be made to rotate at a certain angle (e.g., 1.8 degrees) according to the input signal.

In the present invention, the motor unit 180 can be applied not only to a stepping motor but also to a device capable of rotating a transparent baffle plate and a transparent baffle fixing device (DC / AC / Servo / Brushless DC / Hysteresis / Reluctance / ) Are all applicable. For example, any one of a stepping motor, a DC motor, an AC motor, and a servo motor may be used as the motor.

The motor driving unit drives the motor according to the motor control signal received by the control unit 200, that is, the motor of the control unit 200 and the eyeglass control unit 220.

In the present invention, the number of frames of an image can be adjusted by controlling the rotational speed of the transparent bobbin 150, that is, the rotational speed of the motor. Further, the depth of the three-dimensional image recognized by a person is controlled by controlling the rotation angle of the transparent baffle plate 150, that is, the rotation angle of the motor. The minimum rotation speed of the motor is 24Hz, which is observed without any blinking when the human eye observes the image. The final three-dimensional image is observed seamlessly when the motor is rotated over 24Hz. This does not indicate that the rotation speed of the motor should be more than 24 Hz in the present invention, and in some cases, the rotation speed of the motor may be 24 Hz or less. Preferably, the rotation speed of the motor is 24 Hz or more.

One left image and one right image form one three-dimensional image information when the left-side right image is sequentially acquired. In general, when the image to be displayed per second is 24 frames or more, Therefore, it is necessary to maintain 24 frames per second in three-dimensional images. In order to satisfy this requirement, the rotational speed of the transparent plate must be sufficiently increased.

The camera unit 190 includes a camera 197 and a lens 192.

The lens 192 is an image-forming lens, which is provided at the front end of the camera unit 190, and is located close to the object, and an image of the object to be imaged is incident. And converges the image incident through the lens 192 to form an incident tie point (0).

The camera 197 may be a CMOS camera or a CCD (Charge Coupled Device) camera. The camera 197 sequentially acquires the left eye image and the right eye image based on the vertical frequency outputted from the CCD included in the camera 197 and outputs the same.

The control unit 200 includes a motor and eyeglass control unit 220 and an operation processing unit 240. The motor and eyeglass control unit 220 and the operation processing unit 240 are connected to one microcontrol unit (MCU) ≪ / RTI >

The motor and eyeglass control unit 220 is composed of an MCU and controls the motor unit 180 and the active shutter type eyeglass unit 300. The motor and eyeglass controller 220 generates and outputs a motor control signal for controlling the rotational speed, the rotational direction, and the rotational angle of the motor to the motor unit 180, and outputs the eyeglass control signal to the active shutter type eyeglass unit 300 do.

The motor and eyeglass control unit 220 controls the eyeglass part (right eyeglass lens) of the left eyeglass unit (left eyeglass lens) to be transparent in the active shutter type eyeglass unit 300 when the left image appears on the screen in the video output unit 260, When the right image is displayed on the image output unit 260, the right eyeglass unit (right eyeglass eye) is made transparent in the active shutter type eyeglass unit 300, and the right eyeglass unit And outputs an eyeglass control signal for controlling the portion (left eyeglass lens) to become non-transparent. As a result, the left image is transmitted to the left eye of the person, and the right image is transmitted to the right eye of the human. As a result, the human brain is recognized as three-dimensional information.

Other three-dimensional stereoscopic images are observed in the human eye depending on the rotational speed, direction, and angle of the transparent baffle plate 150. In order to observe the observed images in real time, the rotational direction, the rotational speed, and the stopping time (observation time) of the transparent plate 150 are all synchronized with the glasses of the active shutter type spectacle unit 300 used for the final image observation do. In order to solve this problem, the motor and eyeglass control unit 220 is controlled so that the glasses of the active shutter type eyeglass unit 300 react in synchronization with the rotation of the transparent substrate 150 at a specific time.

The operation processing unit 240 receives the image of the left eye and the image of the right eye output from the camera and transmits the image to the video output unit 260. The operation processing unit 240 may be a computer, a microprocessor, an MCU, or the like.

In some cases, the motor and eyeglass control unit 220 and the operation processing unit 240 may be one operation processing unit, and the control unit 200 controls not only the active shutter type eyeglass unit 300 but also the camera. Since all of the cameras, motors, and glasses are controlled, all parts of the system of the present invention can be synchronized.

The image output unit 260 displays the image received from the operation processing unit 240 on the screen, that is, sequentially outputs the image of the left eye and the image of the right eye. The video output unit 260 may be a monitor, a projector, or the like.

The active shutter type eyeglass unit 300 is a means used to observe an image of the video output unit 260 that sequentially displays the left eye image and the right eye image in real time. The active shutter type spectacles unit 300 includes active shutter type spectacles and an active shutter glass module (not shown).

Referring to Fig. 4, a camera 197 on which a camera unit 190, that is, a lens 192 is mounted, is mounted on a camera mount 199.

The motor housing 181 of the motor unit 180 is mounted on one side of the motor mount 189 while being separated from the camera mount 199 and mounted on the motor mount 189.

A motor and a motor driving unit are built in the inside of the motor housing 181 and the rotary shaft 188 of the motor is coupled with the transparent mold plate 150 through the holes in the upper surface of the motor housing 181.

Referring to FIG. 5, the transparent die plate 150 is inserted into the die plate insert hole 151, which is a through hole provided in the die plate frame 157. A rod-shaped mold frame engaging portion 156 having a middle rotational axis inserting groove 187 is provided on the lower surface of the mold frame 157. The transparent die plate 150 may be cylindrical.

The bobbin case fixing portion 159 is rod-shaped and has a middle rotation shaft insertion groove 187.

In the present invention, when the transparent baffle plate 150 is located at a position closer to the focal distance of the lens 192 of the camera portion, a transparent baffle plate of a smaller size can be used. That is, in addition to the size of the transparent baffle plate 150, the size of the transparent baffle plate may be modified according to the position of the transparent baffle plate. If the lens 192 of the camera unit is made up of a lens system composed of a plurality of lenses, if the transparent plate 150 is positioned between the lens systems of the camera unit, the size of the lens system can be reduced according to the configuration of the lens system to be used .

If the transparent die plate 150 is placed in front of the lens 192 of the camera unit, it should be manufactured in the same size as the lens. However, if the transparent die plate 150 is placed in the lens 192 of the camera unit, the size thereof can be reduced.
