Three-dimensional imaging device and its camera angle adjustment method

Three-dimensional imaging device and its automatic camera angle adjustment method

The demand for the production of three-dimensional immersive contents using virtual reality or augmented reality is continuously increasing.

Here, as a method of producing three-dimensional three-dimensional content, an expert manually models the object of the content one by one, or data processing an image obtained through photography to generate three-dimensional volume metric data in an automated manner. can be heard

In the conventional flat image shooting, one picture is outputted in one direction, but in order to obtain the above-described three-dimensional volume metric data, one subject must be shot simultaneously in all directions, so it is usually 100 units across 360 degrees. You will have to control and shoot many of the above cameras at the same time.

Here, it is necessary to adjust the precision of photographing or to adjust the distance between the subject and the camera according to the size of the subject.

At this time, even if the distance between the subject and the camera is changed, the left and right angles, that is, the PAN angle, do not need to be changed, but the vertical angle, that is, the tilting angle, needs to be readjusted because all cameras are changed.

However, it is very cumbersome and time-consuming to have to change the shooting angles of up to hundreds of cameras every time such distance adjustment is performed.

Invented from the above point of view, the "3D photographing apparatus equipped with a lighting device and a camera apparatus" (hereinafter referred to as Prior Art 1) of Patent Registration No. 10-1817197 and "camera photographing angle" of Patent Publication No. 10-2018-0078106 Adjustment method and apparatus" (hereinafter referred to as prior art 2), and "photographing apparatus, photographing system, and operating method thereof" of Korean Patent Registration No. 10-2085866 (hereinafter referred to as prior art 3), and the like.

Prior art 2 relates to a method and apparatus for automatically adjusting the angle of a camera according to the position of a subject. It is a technology for automatically adjusting the shooting angle of

Prior art 3 detects such a change when the position of the structure on which the lens is mounted is changed so that it can be changed to the original position. This is a technology for automatically correcting the lens direction so that the front can be photographed when not facing the front.

However, the prior art 1 clearly has structural limitations in that it is impossible to change the position of the frame according to the size of the subject or the precision of photographing, and it is impossible to photograph while adjusting the photographing angle of the camera.

And, the prior art 2 is a technology that is limited to the level that can be adopted for smart home devices, and there are clearly limitations that are limited to the use of photographing a human body with a single camera.

In addition, the prior art 3 is limited to the purpose of correcting the original direction by detecting a change in the direction of one structure including the camera in real time, so it is difficult to use it for the purpose of generating three-dimensional volume metric data. have.

That is, the number of installations of the supporters 70 is 6 to 36 depending on the above-described angle range so that the photographing result of the subject 40 is not distorted and can be output in the form of a moving picture or image to the output device as realistically as possible. It will be possible to selectively change and design appropriately within the range.

On the other hand, the present invention extends radially from the edge of the base 60 to adjust the distance from the center of the base 60 to the lower end of each of the plurality of supports 70 as shown in FIG. 2 to provide a plurality of supports (70) It may further include a distance adjusting means 80 for guiding each lower end so that the position can be adjusted.

The distance adjusting means 80 is a movement guide rail 81 extending radially from the edge of the base 60 and arranged so that each inner end faces the center of the base 60, and the movement guide rail 81 It may include a mover 82 that can move along the direction, and a reciprocating actuator 83 that is connected to the mover 82 and transmits a driving force to the mover 82 to reciprocate.

At this time, it can be seen that the lower end of each of the plurality of supports 70 is disposed on the upper surface of the mover 82 .

That is, in the present invention, the focus marking means 30 is disposed at the center of the base 60 , radially along the edge of the base 60 , and each inner end is disposed toward the center of the base 60 . The support 70 provided with a plurality of camera modules 10 along the movement guide rail 81 of the distance adjusting means 80 has a reciprocating structure.

Therefore, in the present invention, when the angle adjustment means 20 tilts only the upper and lower angles of each of the camera modules 10 under the control of the controller 12, a series of angle adjustment processes for matching the specified position and the specific mark are quickly and reliably performed. to be able to do it efficiently.

Meanwhile, the support 70 may be applied to an embodiment of a structure including the first, second, and third bars 71 , 72 and 73 , when looking more specifically with reference to FIG. 3 .

First, a plurality of first bars 71 are radially disposed perpendicular to the base 60 .

The second bar 72 has a first end portion 72a that is obliquely fixed to the lower side of the first bar 71 , and is inclined with respect to the base 60 and is formed on the outside of the base 60 or the edge of the base 60 . It has a fixed second end (72b), and extends downwardly inclined with respect to the lower side of the first bar (71).

The third bar 73 has a third end 73a that is obliquely fixed to the upper side of the first bar 71 , and extends obliquely upward from the third end 73a to the upper side of the first bar 71 . do.

Accordingly, the plurality of camera modules 10 arranged to face the focus marking means 30 by the angle adjusting means 20 to be described later have a third bar 73 and a first bar 71 sequentially from the upper side. ), and it can be grasped that a plurality of second bars 72 are mounted.

In addition, the support 70 is a plurality of fixed installation along the vertical direction of the first bar 71, the intermediate reinforcing frame 74 for fixing and supporting each of the plurality of first bars 71 in a circular ring shape. You may be able to provide more.

On the other hand, the angle adjusting means 20, referring to FIG. 3, with respect to the support 70 on which each of the plurality of camera modules 10 is installed, the camera 11 provided in each of the plurality of camera modules 10 is It may include a hinge 21 for tilting up and down, and a tilting actuator 22 for forward and reverse rotation of the hinge 21 by receiving a driving force.

On the other hand, the focus marking means 30, the support bar 31 and the support bar 31 which are detachably disposed at a designated position as shown in FIG. 3 and stand in the center of the ground, more specifically, the base 60, It is mounted on one side, the camera module 10 may be applied to an embodiment of the structure including the recognizable marking sphere (32).

The marking sphere 32 may be provided in the form of a spherical illumination so that light can be irradiated in all directions so that the camera 11 of each of the camera modules 10, that is, the lens can be clearly recognized.

Of course, the marking sphere 32 may be provided in a spherical shape that omits illumination and the cameras 11 are clearly recognizable under natural light.

Accordingly, each of the plurality of camera modules 10 is tilted up and down by the angle adjusting means 20 so that the lenses of each of the plurality of camera modules 10 are oriented toward the marking sphere 32 .

In other words, as described above, the image taken by each camera module 10 according to the "designated location", that is, whether the marking sphere 32, that is, the "specific mark" is disposed in the "designated location" on the screen. Accordingly, the angle adjustment of the camera module 10 by the angle adjustment means 20 is completed or continued.

That is, in the controller 12, the designated position appearing on the shooting screen, which is the center point on the screen or the point set by the photographer, matches the specific mark that the marking tool 32 provided in the focus marking means 30 appears on the shooting screen. The conversion angle is calculated and determined by comparing the

Therefore, as the controller 12 gives an angle adjustment command to the angle adjustment means 20, if the angle adjustment means 20 tilts only the upper and lower angles of each of the camera modules 10, a series of matching the specified position and the specific mark It will be possible to perform the angle adjustment process quickly, reliably and efficiently.

Hereinafter, a method for automatically adjusting a large amount of camera angle for three-dimensional imaging according to various embodiments of the present invention will be described in more detail with reference to FIGS. 1 to 3 and FIGS. 4 and 5 .

For reference, in the embodiment shown in FIG. 4 , the position of the camera module 10 is moved forward or backward by the distance adjusting means 80 before or after the subject 40 is photographed, and then the angle is adjusted. It can be said to be a series of algorithms that are started for

First, the focus marking means 30 is arranged in the center of the base 60 to photograph the subject 40 , and an image is taken in which the plurality of camera modules 10 capture the image of the focus marking means 30 .

The object of image capturing here is not the subject 40 but the marking sphere 32 of the focus marking means 30 .

Thereafter, a specific mark, which is the position of the marking sphere 32 provided in the focus marking means 30 displayed in the captured image of each of the plurality of camera modules 10 output on the screen, is a point set to photograph the subject 40 . The camera processor 50 compares and analyzes whether it matches the designated position.

At this time, if the specific mark and the designated position do not match the output on the screen as shown in FIG. 5 , the controller 12 operates the angle adjusting means 20 provided in each of the plurality of camera modules 10 , so that the plurality of camera modules (10) By adjusting each angle, the specific mark and the specified position are matched.

That is, if each of the camera modules 10 exactly faces the marking sphere 32, the specific mark and the specified position will be output on the screen to match, but if the specific mark and the specified position do not match, the white point below the specified position or Since a specific mark, which is a red dot above, will be output, the process of matching these white and red dots to one point is necessary.

Therefore, the focus marking means 30 is positioned in the center of the base 60, and then the focus marking means 30 is photographed, and then the controller 12 sees the image taken on the screen and checks whether the specified position and the specific mark match. After determining, the camera processor 50 determines whether to issue an angle adjustment command to the controller 12 provided in each of the plurality of camera modules 10 according to whether the specified position and the specific mark match or do not match.

In other words, it can be said that the embodiment shown in FIG. 4 shows the angle adjustment process of the angle adjustment means 20 according to the controller 12 gives an angle adjustment command to the angle adjustment means 20 .

Therefore, if the image captured by each of the plurality of camera modules 10 is checked through the screen as shown in FIG. 5 , a white dot will be seen in the center of the screen, and the white dot is a “designated position” preset by the photographer as described above. "It will be

If the white dot indicating the "designated position" is not seen, and the red dot "specific mark", that is, the position where the marking sphere 32 was photographed, is visible in the place where the white dot should be, that is, the "designated position" and the "specific mark" match In this case, it is enough to remove the focus marking means 30 from the base 60 and position the subject 40 to start the main photographing.

However, when a white dot indicating a “designated position” and a red dot indicating a “specific mark” are seen together, that is, a “specific mark” is located below or above the “designated position” as shown in FIGS. 5(a) and 5(b). When it appears, as described above, the camera processor 50 transmits the angle adjustment command of the angle adjustment means 20 to the controller 12 provided in each of the camera modules 10 .

That is, as described above, the controller 12 compares whether the "designated position" matches the "specific mark" that the marking sphere 32 appears on the shooting screen, and is below or below the "designated position" according to a preset angular function. It is to calculate and determine the transformation angle required to match the "specific mark" located above with the "designated position".

Therefore, when the controller 12 gives an angle adjustment command to the angle adjustment means 20 by the conversion angle calculated by the preset angle function, the angle adjustment means 20 adjusts the angle corresponding to the conversion angle to the camera module ( 10) By tilting each up and down, the specified position and the specific mark are matched as shown in FIGS. 5(a) and 5(b).

Thereafter, the angle adjustment means 20 receives the angle adjustment command of the controller 12 and adjusts the angle of the camera module 10 from bottom to top as shown in FIG. 5(a), or from top to bottom as shown in FIG. 5(b). By tilting, when the "designated position" and the "specific mark" are matched, that is, only the red dot is visible, the main shooting using the subject 40 can be started.

As described above, the present invention provides a three-dimensional imaging apparatus and an automatic camera angle adjustment method thereof, which can reduce the time and cost required for three-dimensional imaging by enabling the camera angle adjustment operation to be automatically and simultaneously executed in each camera. It can be seen that the basic technical idea is to provide.

And, within the scope of the basic technical spirit of the present invention, many other modifications and applications are also possible for those of ordinary skill in the art.
