Description

Track for stereoscopic recording {3d photo track}

The present invention is a transfer device for producing a high-resolution stereoscopic image as a device for transporting a high-resolution stereoscopic image in a near distance circumferentially moving the distance between the main subject and the recording device with a radius value in high-speed continuous shooting, or when moving in a long distance in parallel Designed to shoot high-speed continuous shooting, this is a 3D recording track. The distance between the shooting device and the main subject, the size of the whole subject, and the continuous shooting speed of the shooting device can be adjusted. When the distance between the subject and the photographing device is set to a radius value, the material of the variable orbit is made of an elastic material and the radius value of the variable orbit can be freely adjusted, and the head fixing part coupled to one moving rotation shaft and two roller contacts The camera is connected to a known camera head and fixed at the top of the main subject. As the axis of rotation is rotated counterclockwise at the same time, toward the center point of the circumference, at the same time, the circumferential movement is carried out and high-speed continuous shooting is performed. Therefore, all the image information of a plurality of shots taken at regular intervals or at an angle are placed so that the main subject is in the center position. Since the images are superimposed, there is no problem of resolution loss when using only the superimposed image after cutting out the non-overlapping part, which is a problem of the two-dimensional or multi-eye photographing method, which is a general stereoscopic image capturing method. Or it is a three-dimensional image recording track having a linear orbital and orbital curve trajectory designed to represent a stereoscopic image as the highest resolution value of the film.

As a general shooting method used to produce a three-dimensional image of the conventional left using a binocular camera or a multi-eye camera. The method of taking images of the right eye at the same time and the method of taking a left eye image using a single general camera first, and then moving the right eye image by about the distance of both eyes to the right side are used. A slider having a simple structure was assembled with the camera to prevent the back from occurring. In addition, the shooting method for producing a three-dimensional image also did not deviate significantly from the above-described shooting method, two cameras (camcorder) were installed in the horizontal direction of the binocular distance, respectively, and then the method of shooting was mainly used.

However, the image information of 2 to 5 cuts obtained by such a photographing method is remarkably insufficient compared to the total amount of image information that a person sees with his eyes and feels in three dimensions in the brain, and is produced only by the image information obtained by the photographing method. The resulting 3D image is dizzying for many people. headache. It also caused a feeling of vomiting, which led to serious problems that slowed the development of the 3D industry as a whole.

In order to solve these problems, some stereoscopic enthusiasts can shoot 10 different cameras horizontally and synchronize them as a way to increase the total amount of image information that can be obtained when shooting, or even modify several cameras at once. In some cases, the camera was produced like a camera, but due to the size of the camera itself, it was impossible to shoot at close intervals, and the parallax value was so large that it was taken out of a certain interval among the images taken due to the nature of lenticular lenses. There is a problem that can not be used, and even spherical aberration for each camera lens even with the same camera. Although the optical characteristics of the lens, such as chromatic aberration, are minute but different from each other, they are not suitable as a photographing method for producing a high-resolution three-dimensional image.

Therefore, the present invention is to solve the above problems, while using a high-speed continuous shooting function or a Full HD video recording function of the recently marketed shooting device to move the photographing equipment in parallel or circumferentially to match the type of the subject It is intended to provide a track for stereoscopic imagery that can be configured so that the direction of the photographing equipment always faces the main subject, and easily obtain sufficient image information to produce high-resolution stereoscopic images by using a high-speed continuous shooting method using a single photographing device. .

The three-dimensional image recording track for easily obtaining image information of multiple cuts with a single photographing device is a slider in which an x-axis linear motion guide (1) of about 1 m and a y-axis linear motion guide (2) of about 30 cm are orthogonally assembled. It has a structure of the form, two fixed tracks (3) made of an elastic material pipe or rod is parallel to the x-axis linear motion guide (1) and assembled with the radial value adjusting nut (10) at both ends Axis of rotation

It is fixed to (11) and configured to be parallel and circumferential movement, the head fixing portion 5 assembled with the upper block (4) of the y-axis linear motion guide (2) has one moving rotary shaft (6) and two places Composed of the roller contact portion (7) and coupled with the variable orbit (3), by adjusting the radius value adjusting nut (10) installed at both ends of the variable orbit (3), forward and reverse rotation to capture the shape of the variable orbit (3) The distance between the device and the main subject can be varied in the shape of a bow with a radius value.

In addition, a well-known 3-way head 9 or a ball head 9 is used together with a photographing apparatus at the upper end of the head fixing part 5 of the three-dimensional image recording track. Cut the required image according to the combination of the number of shots, the point-per-inch (LPI) depending on the type of lenticular lens, and the output resolution of the final stereoscopic image and the point-per-inch (LPI) of the lenticular lens). In consideration of the lighting of different numbers, the motor driving device and the control unit 8 of the x-axis linear motion guide 1, which can control the movement distance and the acceleration / deceleration, to suit the inherent characteristics of the photographing apparatus used, are included. , The stopper 12 and the leaf spring 13 are closely assembled to both lower ends of the two fixed rotary shafts 11 assembled with the radius value adjusting nuts 10 installed at both ends of the variable track 3, and thus the two fixed rotary shafts The left side of (11) is clock room On the right side, since the proper rotational tension is always generated to rotate in the counterclockwise direction, and also due to the influence of the tension spring 14 connected from the front direction, the head fixing portion 5 always generates an appropriate tension that is pulled in the forward direction, Hunting (shake), which can occur when the motor is sometimes under load during continuous shooting, is prevented, so that high-speed continuous shooting can be performed smoothly during parallel movement or circumferential movement of the photographing equipment. You can do it.

In addition, the head fixing part 5 is connected to the upper block 4 of the y-axis linear motion guide 2 and one moving rotation shaft 6 connected to the tension spring 14 from the front direction, and then two rollers. Since the contact portion 7 is configured to be connected and assembled with the variable track 3, the photographing apparatus assembled with the known 3-way head 9 or the ball head 9 at the top of the head fixing portion 5 is always main. A direction toward the subject, that is, a center point of the circumference, is rotated at a low speed in the counterclockwise direction with respect to the central axis of rotation 6, and circumferentially moved, and high-speed continuous shooting can be taken at an angle. Since the main subject is always placed in the center of the captured image file or film, the loss of image information does not appear at all when rearranging the images of a plurality of shots and making a stereoscopic image on a lenticular lens or a parallax barrier screen. It is possible to provide a three-dimensional image recording track that can easily obtain a large number of cut image information sufficient to produce a high-resolution three-dimensional image.

As described above, by using the three-dimensional image recording track according to the present invention, by using a high-speed continuous shooting function or a Full HD video recording function of near-by-person or far-to-mainly landscape, the circumferential movement or When moving in parallel and expanding the parallax value for the purpose of increasing the average binocular distance or three-dimensional sensitivity of a person, when shooting beyond the binocular distance, the high resolution of multiple cuts per very close angle or interval without the limitation of the shooting interval due to the size of the recording device itself There is an effect that can easily obtain image information.

In addition, in the conventional stereoscopic imaging method, since the non-overlapping portion is cut out and only the overlapped image information is used, there is a problem in that the maximum resolution inherent in the photographing apparatus cannot be properly expressed. Since the depth of field of the device becomes very shallow, the conventional photographing method such as moving in parallel to the front face is different from the point of focus of the photographing device toward the left eye image and the right eye image, and from the left and right lens positions to the respective focus positions. Since the distances are not exactly matched, the images of the left and right eyes formed on the film or the image sensor due to the minute distance difference are often taken unclearly, which makes it difficult to produce a high resolution stereoscopic image. Jupiter when taking close-up shots of people using the shooting track With the focus on exactly one part of the chain portrait, the radius adjustment nut 10 is forward and backward adjusted to set the distance between the photographing device and the focus position as the radius value. After adjusting the variable trajectory (3) in a curved shape, high-speed continuous shooting is performed with a single photographing device, so that even when taking a close-up shot of a shallow depth of field or the like, the sharp image information of multiple cuts superimposed at every fine angle Can be obtained easily.In particular, when producing high resolution stereoscopic image by capturing image information acquired by Full HD video recording technique and rearranging it to lenticular lens, video or animation effect is about 5-6 seconds. It can be expressed as, it is possible to produce time-consuming high-resolution 4D photos.

Therefore, when the present invention is described in detail with reference to the three-dimensional image recording track as described above, the x-axis linear motion guide (1) of about 1m and the y-axis linear motion guide (2) of about 30cm in the form of an orthogonal slider shape The variable track 3, which is made of an elastic material pipe or rod, is parallel to the x-axis linear motion guide 1 and has a double track, and is a three-dimensional image recording track, and at both ends of the variable track 3 Two fixed rotation shaft 11 including the radius value adjusting nut 10 is fixed to the outside of the stroke away from the x-axis linear motion guide (1).

At this time, the motor drive device and the control unit 8 that can adjust the movement speed and the movement distance when the parallel movement of the x-axis linear motion guide (1) is included, and although not shown in the figure, the upper block of the x-axis linear motion guide and y When the linear motion guide is assembled in the form of an orthogonal slider, it is connected by one rotational axis. When shooting, it is maintained at an orthogonal state, that is, at an angle of 90 degrees. and a positioning screw portion configured to hold the y-axis linear motion guides in parallel with each other.

In addition, the head fixing part 5 is assembled with the upper block 4 of the y-axis linear motion guide 2 and one moving rotational shaft 6 connected to the tension spring 14 from the front direction, and again two The roller contact portion 7 is coupled to the variable trajectory 3, and the radial value adjusting nut 10 installed at both ends of the variable trajectory 3 is forward and reverse rotated to straighten the shape of the variable trajectory 3. Or it is possible to variably adjust the shape of the arch, so when taking a distant picture, the trajectory (3) can be made in a straight line to move in parallel. In the case of near-field photography, the shape of the variable trajectory (3) is formed in the shape of a bow-shaped curve having the distance between the photographing device and the main subject as a radius value so that the focusing point of the photographing apparatus can be adjusted to the main subject so that the high-speed continuous shooting can be performed. do.

Therefore, when taking close-up pictures of people, the recording equipment always faces a fixed focus position before the start of shooting. Therefore, the camera moves circumferentially and rotates circumferentially at the center of the rotational axis (6). Since the captured image information is always superimposed on a specific position of the main subject in a state where all of the images are superimposed, the alignment is performed when rearranging images of a plurality of cuts, which is the first step in the process of expressing a stereoscopic image on a lenticular lens after shooting. In addition to the advantage that the process is not necessary, it is possible to easily obtain a high-resolution image of a large number of cuts without losing image information, thereby producing a high-quality, high-resolution stereoscopic final result.

In addition, as described above, the stopper 12 and the leaf spring 13 are closely assembled to both lower ends of the fixed rotation shaft 11 provided at both ends of the variable track 3, so that the left side of the two fixed rotation shafts 11 In the clockwise direction, an appropriate rotational tension is generated to rotate in the counterclockwise direction and an appropriate tension is generated in which the head fixing part 5 is pulled in the forward direction under the influence of the tension spring 14, so that the parallel movement of the photographing apparatus is performed. Alternatively, silent high-speed continuous shooting can be performed when moving circumferentially, and hunting can be prevented, which can occur when the motor is sometimes subjected to a load during continuous shooting.

Although not shown in the drawing, the lower end of both ends of the three-dimensional image recording track configured as described above includes a screw for fastening the tripod for coupling with a known tripod, and the upper part of the head fixing part 5 has a well-known 3-way head 9. Alternatively, the ball head 9 may be assembled with a photographing apparatus to adjust the distance between the photographing apparatus and the main subject as a focal length, that is, to a radius value of a curved orbit, when photographing a person or a landscape at a long distance. By adjusting the shape, it is possible to provide an optimized photographing method in each case, and to complete a stereoscopic image recording track having straight and variable curve trajectories, which can easily obtain high-resolution stereoscopic image information of multiple cuts.
