The apparatus for acquiring a 3D image according to the present embodiment includes first and second cameras 11 and 12 having a zoom function, a position adjusting means 20, a direction adjusting means 23, and a position adjusting part 31. It is done by The position adjusting means 20 here comprises a horizontal gap adjusting means 21 and a height adjusting means 22.

The first camera 11 and the second camera 12 are arranged horizontally, i.e., at the same height, toward the subject (not shown), and the zoom in or zoom out is synchronized and performed simultaneously. In this embodiment, the first camera 11 becomes a left eye camera, and the second camera 12 becomes a right eye camera.

The position adjustment means 20 is equipped with the 1st and 2nd cameras 11 and 12, and adjusts the position of the 1st and 2nd cameras 11 and 12 under control of the position adjustment part 31. As shown in FIG.

In detail, the first camera 11 and the second camera 12 are mounted to the horizontal gap adjusting means 21, and the horizontal gap adjusting means 21 is disposed between the first camera 11 and the second camera 12. Adjust the horizontal gap. In addition, the first camera 11 and the second camera 12 are also mounted to the height adjusting means 22, and the height adjusting means 22 is the height of the first camera 11 and the second camera 12. Adjust it.

The first camera 11 and the second camera 12 are also mounted to the direction adjusting means 23, and the direction adjusting means 23 adjusts the directions of the first camera 11 and the second camera 12. do.

The position adjusting unit 31 controls the horizontal interval adjusting means 21 and the height adjusting means 22 according to the position and the zoom distance of the subject when the zoom function of the first camera 11 and the second camera 12 is performed. To adjust the positions of the first camera 11 and the second camera 12. In addition, when the zooming function of the first camera 11 and the second camera 12 is performed, the position adjusting unit 31 controls the direction adjusting means 23 according to the position and the zoom distance of the subject, thereby controlling the first camera 11. ) And the second camera 12 can also be adjusted.

2, 3A, and 3B, the position adjusting unit 31 controls the horizontal gap adjusting means 21 and the height adjusting means 22, respectively, so that the first camera 11 and the second camera according to the position and the zoom distance of the subject. It is a figure for demonstrating an example of the mode of adjusting the position of (12).

Referring to FIG. 2, when the initial positions of the first camera 11 and the second camera 12 are referred to as L0 and R0, respectively, the center of the subject 40 is focused and the first camera 11 and the second camera 12 are focused. When the zoom-in function is performed with respect to the camera 12, the virtual left eye position (left eye camera position in the case of a different person) and the virtual right eye position (right eye camera position in the case of a different person) according to the position of the subject 40 and the zoom distance. Can be determined as shown. In this case, the zoom distance is defined as the distance to the point where the camera is located. In other words, it is defined as the distance between the point and the camera using the zoom, in which the subject of interest is the same size.

According to the zoom-in, the position adjusting unit 31 is horizontal to obtain the effect of viewing the subject 40 at the actual close position, that is, the virtual left eye position (the left eye position of Daliin) and the virtual right eye position (the right eye position of Daliin). The gap adjusting means 21 is controlled to widen the horizontal gap between the first camera 11 and the second camera 12. That is, the horizontal distance between the first camera 11 and the second camera 12 is widened so that the first camera 11 is at the L1 position and the second camera 12 is at the L2 position. In this case, it is assumed that the subject is located at the center of the left and right eye cameras, and the moving direction of the camera may change as the position of the subject changes.

The position adjuster 31 receives zoom distance information according to zoom-in or zoom-out from the first camera 11 and the second camera 12, estimates the position of the subject, In order to obtain a three-dimensional image of the difference effect, the first camera 11 and the second camera 12 determine the horizontal spacing, thereby controlling the horizontal spacing adjusting means 21.

Although not shown, the position adjusting unit 31 controls the horizontal gap adjusting means 21 to narrow the horizontal gap between the first camera 11 and the second camera 12 at the time of zooming out.

Referring to FIG. 3A, when the initial height of the first camera 11 is referred to as H0, the zoom-in function is performed. In order to obtain, the position adjustment part 31 controls the height adjustment means 22, and raises the height which is the 1st camera 11 above initial stage, and moves to H1. Here, the virtual eye position means the left eye camera position in the case of Dalyn. The second camera 12 is also adjusted to the same height as the first camera 11 by the height adjusting means 22. This assumes that the subject is at a lower position than the left and right eye cameras, and the vertical movement direction of the camera may change as the height of the subject changes. For example, when the position of the subject is higher than the height of the camera, in order to obtain the effect (different) of viewing the subject 40 at the actual position (virtual eye position), the position adjusting unit 31 is the height adjusting means 22. ), The height of the first camera 11 must be lowered than the initial height. Referring to FIG. 3B, as a result of the zooming, the first camera 11 is moved to H2 with the height lower than the initial height.

The position adjusting unit 31 has a predetermined rule for the height change amount according to the zoom distance according to the zoom distance received from the first camera 11 and the second camera 12 and the estimated position information of the subject. 11) and the height of the second camera 12 can be adjusted.

Although not shown, the position adjusting unit 31 may also control the height adjusting means 22 to reduce or increase the height of the first camera 11 and the second camera 12 when zooming out.

4 is a view for explaining an example in which the position adjusting unit 31 controls the direction adjusting means 23 to adjust the directions of the first camera 11 and the second camera 12.

Referring to FIG. 4, the horizontal gap between the first camera 11 and the second camera 12 is widened by the horizontal gap adjusting means 21 so that the first camera 11 is positioned at the L1 position, and the second camera 12 is positioned. ) Comes to the L2 position, the position adjusting unit 31 controls the direction adjusting means 23 to rotate the first camera 11 clockwise by θ and the second camera 12 counterclockwise by θ. This adjusts the viewpoint so as to more precisely face the subject 40. Here, θ is determined by the virtual left and right eye position (otherwise left and right eye camera position), subject position, zoom distance, and the like.

The position adjuster 31 receives zoom distance information according to zoom-in or zoom-out from the first camera 11 and the second camera 12, grasps the position of the subject, and based on this, the first camera 11 and the second camera 12. The rotation angle of the camera 12 is determined and the direction adjusting means 23 is controlled accordingly.

FIG. 5 is a view for explaining another example in which the position adjusting unit 31 adjusts the position of the first camera 11 and the second camera 12 by controlling the horizontal gap adjusting means 21. .

Referring to FIG. 5, the optimum camera position needs to be changed according to the focus of the camera (position of the subject of interest). For example, when the first camera 11 and the second camera 12 are focused on the point O1 of the subject 40, the first and second cameras 11 and 12 may be configured as described with reference to FIG. 2 according to the zoom-in. They should be moved horizontally to L1 and R1 respectively. However, when the first camera 11 and the second camera 12 are focused at the O2 point of the subject 40, the first and second cameras 11 and 12 should be horizontally moved to L2 and R2 according to the zoom-in. do. Therefore, if the subject of interest is not a point, it is effective to acquire images from various locations to obtain a three-dimensional image of the effect. Therefore, in the present embodiment, when the zoom function of the first and second cameras 11 and 12 is performed, the position adjusting unit 31 controls the horizontal gap adjusting means 21 to control the first and second cameras 11, 12 to move to one position (eg, L1, R1) to obtain an image, and again control the horizontal spacing means 21 to move the first and second cameras 11, 12 to another position (eg For example, move to L2 and R2 to obtain an image. Of course, the position adjusting unit 31 may move the first and second cameras 11 and 12 to a position other than the two positions so that an image is acquired at the position. For example, the first camera 11 may be positioned between L1 and L2, and the second camera 12 may be located between R1 and R2 to acquire an image, thereby obtaining an image having the focus of the camera as a point between O1 and O2. have.

In addition, the first camera 11 moves from L1 to L2, and the second camera 12 moves from R1 to R2, and acquires a plurality of images in succession to synthesize 3D images of different effects. Can be. That is, the image synthesizing unit (not shown) synthesizes the images acquired at the plurality of positions to obtain a three-dimensional image of a new different effect. That is, a new 3D image may be generated by extracting pixels corresponding to respective positions from the plurality of images. For example, in FIG. 5, the pixel value corresponding to O1 at the right eye camera position, which is different, may be estimated from the pixel value of the zoom-in image acquired at R1, and the pixel value corresponding to O2 at the right eye camera position, which is different, is zoomed at R2 It can be estimated from the pixel value of the image. Similarly, the pixel value corresponding to O1 at the left-eye camera position, which is different, can be estimated from the pixel value of the zoom-in image obtained at L1, and the pixel value corresponding to O2 at the right-eye camera position, which is different, at the left-eye camera position, the pixel of the zoom-in image acquired at L2 It can be estimated from the value.

FIG. 6 is a diagram for describing an image of an intermediate view as shown in FIG. 5 according to another embodiment of the present invention. Referring to FIG. 6, the apparatus for acquiring a 3D image further includes a third camera 13 and a fourth camera 14 in addition to the first camera 11 and the second camera 12. The horizontal spacing adjusting unit 21 may adjust the horizontal spacing of the third camera 13 and the fourth camera 14 separately from the first camera 11 and the second camera 12, and the position adjusting unit 31 may be When the zooming function of the cameras is performed, the first to fourth cameras 11, 12, 13, and 14 are moved left and right so that the focuses of the cameras are formed on the plurality of points on the subject of interest 40, respectively. To obtain.

Referring to FIG. 6, the first and second cameras 11 and 12 move to L1 and R1 positions, respectively, to acquire an image focusing on the left end of the subject 40 of interest, and the third and fourth cameras 13 and 14 move to L2 and R2 positions to obtain an image having the focus on the right end of the subject 40 of interest.

An image synthesizer (not shown) synthesizes images acquired at a plurality of positions by the first to fourth cameras 11, 12, 13, and 14 to generate a new three-dimensional image of a different effect. That is, a new three-dimensional image of a different effect may be generated by extracting pixels corresponding to respective positions from the plurality of images. If additional cameras can be installed, it is possible to obtain an improved three-dimensional image of an otherwise different effect by determining their positions according to the zoom distance after installing additional cameras.

7 is a block diagram of a 3D image acquisition device according to another embodiment of the present invention. 3D image acquisition apparatus according to the present embodiment, the first camera having a zoom function and the second camera (71, 72), the first moving means 81, the second camera 71 is mounted, the second camera It comprises a second moving means 82, and the position adjusting portion 91 to be mounted.

The first camera 71 and the second camera 72 face the same subject (not shown), and the zoom in or zoom out is synchronized and performed simultaneously.

The first moving means 81, the second moving means 82, and the position adjusting unit 91 each have a communication means (e.g., a wireless communication means such as Bluetooth, Zigbee, etc.), and the position is obtained by using the communication means. The adjusting unit 91 transmits and receives information with the first moving unit 81 and the second moving unit 82.

The position adjusting unit 91 receives zoom distance information according to zoom-in or zoom-out from the first camera 71 and the second camera 72, and based on this, the first moving unit 81 and the second using the communication unit. The moving means 82 is controlled to move the first camera 71 and the second camera 72.

Specifically, assuming that the subject is located in the middle of two cameras, the first moving means 81 and the second moving means 82 make the interval between the first camera 71 and the second camera 72 wide when zoomed in. ), And controls the first moving means 81 and the second moving means 82 to narrow the interval between the first camera 71 and the second camera 72 at the time of zooming out. Here, an example in which the distance between the first camera 71 and the second camera 72 is adjusted according to the zoom is the same as that described with reference to FIG. 2, and thus a detailed description thereof will be omitted.

At the same time, assuming that the subject is located at a position lower than the two cameras, the first moving means 81 and the second moving means increase the height of the first camera 71 and the second camera 72 when zooming in. The first moving means 81 and the second moving means 82 are controlled so that the heights of the first camera 71 and the second camera 72 are lowered at the time of zooming out. Here, an example in which the heights of the first camera 71 and the second camera 72 are adjusted according to the zoom is the same as described with reference to FIGS. 3A and 3B, and thus, detailed description thereof will be omitted.

At the same time, when the zoom function is performed, the directions of the first camera 71 and the second camera 72 are adjusted. For example, when the zoom-in function is performed, as the horizontal distance between the first camera 71 and the second camera 72 becomes wider, the first camera 81 and the second camera 82 are controlled to respectively control the first camera. The angle of the camera is adjusted so that the 71 and the second camera 72 face the subject more accurately. Here, an example in which the viewpoints of the first camera 71 and the second camera 72 are adjusted according to the zoom is the same as that described with reference to FIG. 4, and thus a detailed description thereof will be omitted. Of course, the angle of the camera may change according to the position of the subject.

In addition, when the zoom function of the first and second cameras 71 and 72 is performed, the position adjusting unit 91 controls the first moving means 81 and the second moving means 82 to control the first and second movements. The cameras 71 and 72 may be moved to one position to acquire an image, and the first movement means 81 and the second movement means 82 may be controlled to move to another position to acquire an image. . In this case, the image synthesizing unit (not shown) synthesizes images acquired at a plurality of positions to obtain a three-dimensional image of a new different effect. That is, a new three-dimensional image of a different effect may be generated by extracting pixels corresponding to respective positions from the plurality of images. Here, an example in which images are acquired at a plurality of positions by the first and second cameras 71 and 72 is the same as described with reference to FIG. 5, and thus a detailed description thereof will be omitted.

The image acquisition apparatus according to the embodiment shown in FIG. 7 may be applied to a three-dimensional image acquisition apparatus having a wide distance between two cameras, which is mounted on a satellite or an airplane for satellite photographing or survey photography.

In many cases, the spacing of three-dimensional cameras is limited physically. In another embodiment of the present invention, in order to solve this problem, the direction of the camera is changed according to the zoom distance to acquire an image and correct it to obtain an image of an effect differently.

8 is a block diagram of an apparatus for acquiring a 3D image according to another exemplary embodiment. The 3D image acquisition apparatus according to the present embodiment includes a first camera 101 and a second camera 102 having a zoom function, a direction adjusting means 111, and a direction adjusting part 121.

The first camera 101 and the second camera 102 are arranged horizontally, i.e., at the same height, toward the subject (not shown), and the zoom in or zoom out is synchronized and performed simultaneously.

The direction adjusting means 111 is equipped with the first and second cameras 101 and 102, and independently adjusts the directions of the first and second cameras 101 and 102 under the control of the direction adjusting part 121.

When the zoom function is performed, the direction adjusting unit 121 controls the direction adjusting means 111 to adjust the directions of the first and second cameras 101 and 102 according to the zoom distance and the position of the subject. In addition, the direction adjusting unit 121 controls the direction adjusting means 111 to acquire a plurality of images while changing the directions of the first and second cameras 101 and 102, and the image synthesizing unit (not shown) Synthesize a plurality of images to generate a three-dimensional image of the effect otherwise.

As a modified embodiment, the three-dimensional acquired imaging apparatus further includes an additional camera having a zoom function, and the additional camera is also mounted on the direction adjusting means 111. The additional camera also acquires a plurality of images at different positions and directions from the first and second cameras 101 and 102 under the control of the direction adjusting unit 121, and the image synthesizing unit (not shown) may be used as the first and second cameras. By synthesizing the plurality of images acquired from the additional cameras 101 and 102 with each other, a three-dimensional image of an effect is generated.

That is, referring to FIG. 9, in order to obtain an accurate different effect, the right eye camera needs to be moved from the L0 position (home position) to the L1 position, and the left eye camera moves from the R0 position (home position) to the R1 position. . However, if it is impossible to physically change the distance of the camera, the next best way is to change the direction of the camera without changing the position of the camera. In this case, some distortion may occur, but an image capable of similarly utilizing the three-dimensional effect of the Dane may be synthesized. Accordingly, as shown in FIG. 10, in the present embodiment, the direction adjusting unit 121 changes the left eye camera and the right eye camera independently.

If the subject is not a point, the direction adjusting unit 121 acquires a plurality of images while changing the directions of the left and right eye cameras, and synthesizes the images to generate a three-dimensional image of the effect. Synthesis may be performed similarly to the method described above with reference to the example of FIG. 5. In this case, of course, it is impossible and approximated to accurately reconstruct the disparity image.

In addition, as shown in FIG. 11, the left eye camera group and the right eye camera group may be configured with a plurality of cameras facing in different directions to configure a 3D image acquisition device having an effect zoom function. In this case, a plurality of left eye images and a plurality of right eye images may be obtained and then synthesized to generate a three-dimensional image of an effect differently. In this case, of course, the plurality of cameras may be designed to change directions independently.
