The present invention relates to a three-dimensional integrated imaging method, a system and a recording medium on which a program for executing the same is recorded. More particularly, the present invention relates to a three-dimensional integrated imaging method, a system and a recording medium on which a program for executing the same are recorded. will be.

 Recently, researches on 3D image and image reproducing technology have been actively conducted, and have attracted much attention all over the world. Imaging technology is advanced and high technology integration is taking place. Accordingly, the demand for 3D images is increasing because 3D images are more realistic, natural, and closer to humans than 2D images.

3D image reproducing technology refers to a technology of displaying a stereoscopic image so that an observer can feel a three-dimensional and realistic three-dimensional image rather than a flat image. Currently, various techniques such as stereoscopy, holography, and integrated imaging techniques have been researched and developed to reproduce 3D stereoscopic images.

Stereoscopy is a method that mimics the human visual system. In the stereoscopic method, images corresponding to both left and right eyes are distinguished and inputted respectively. In other words, the stereoscopic method divides an image into a left eye image and a right eye image, and then enters the left and right eyes of an observer wearing glasses made of polarized liquid crystal plates, respectively, to make a stereoscopic image. The stereoscopic method is the simplest structure that makes a stereoscopic sense through stereo disparity using left and right images.

 However, stereoscopic methods are generally limited to horizontal parallax. In addition, the difference between the parallax of the two images coming into both eyes and the focus function of the human being causes dizziness and eye fatigue. Therefore, the stereo system has been greatly limited in use as a long time stereoscopic image reproducing system.

In the holography method, when a light source is illuminated on the holography, an observer observes a virtual image of the virtual image while looking at the holography at a certain distance from the front of the holography. The holography method is a method of observing holography produced using a laser, and it is possible to feel the same stereoscopic image as the real one without wearing special glasses. Therefore, the holography method is known to be the most ideal way to feel the three-dimensional image without the fatigue and excellent stereoscopic feeling.

However, the holography method not only has to synthesize holograms using a laser in a dark room, but also has a problem in that the light source used is limited and expresses a long distance object. In addition, the holography method is difficult to real-time transmission and image playback due to the excessive amount of information of the conventional method is substantially limited in practical applications.

Integrated imaging was first proposed in 1908 by Lippmann. Since then, the integrated image method has been studied with the next generation 3D image reproduction technology. However, the integrated imaging method has not received much attention during that time. However, the integrated image method has recently received great attention due to the development of a high-resolution image detection device such as a flat display device such as a liquid crystal display (LCD) and an image sensor (Charge Coupled Device (CCD)).

In general, integrated image technology is largely divided into an image acquisition step and an image reproduction step. The image acquisition step consists of a two-dimensional detector such as an image sensor and a lens array, wherein the three-dimensional object is located in front of the lens array. Various image information of the 3D object is then passed through the lens array and stored in the 2D detector. At this time, the stored image is used for 3D reproduction as an element image. The image reproducing step of the integrated image technology is a reverse process of the image acquiring step, and the image reproducing device such as a liquid crystal display and a lens array (the image reproducing step is referred to as a lens array hereinafter to distinguish it from the lens array of the image acquiring step). It is composed. Here, the element image obtained in the image acquisition process is displayed on the image reproducing apparatus, and the image information of the element image passes through the lens array to be reproduced as a 3D image in space.

Integrated imaging has the advantage of providing full parallax and continuous view like holography. The main feature of the integrated imaging method is that it does not require glasses or other tools to observe stereoscopic images and can provide continuous vertical and horizontal parallax within a certain viewing angle rather than a viewpoint. In addition, the integrated image system is capable of reproducing a full color real-time image, and is highly compatible with a conventional planar image device.

However, despite the many advantages, the integrated image method requires much improvement in view angle, depth, and resolution to achieve full commercialization. In addition, according to the technology of the image reproducing apparatus in the image acquisition step has a problem that different methods should be used.

Accordingly, the present invention has been made to solve the above problems, the present invention provides a three-dimensional integrated image method and system that can display a three-dimensional integrated image regardless of the technology of the image reproducing apparatus using a depth map. It is to.

In addition, the present invention is to provide a three-dimensional integrated imaging method and system in terms of depth and resolution using the element image.

In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a view for explaining a three-dimensional integrated imaging system using a component image according to a first embodiment of the present invention, Figure 2 is a view for obtaining a two-dimensional image and depth map of an active depth camera according to an embodiment of the present invention It is a figure for demonstrating.

As shown in FIG. 1, in the 3D integrated imaging system using an element image according to an exemplary embodiment, an image input unit 100, a sectioning image processor 200, and an element image generator 300 may be used. And an image reproducing unit 400.

The image input unit 100 obtains an image from the 3D object 500. The acquired image may include a 2D image 111 and a depth map 112. The image acquisition method may be, for example, image acquisition using a lens array, image acquisition using a stereo camera or an active camera.

Here, the 3D object 500 includes one 3D object 500 or a plurality of objects positioned on the 3D space to be an imaging object. That is, in the latter case, the individual objects may be two-dimensional objects, but by being located together in three-dimensional space, one three-dimensional object 500 that becomes the imaging object of the present invention may be formed.

In general integrated imaging technology, a basic array of images is acquired using a lens array. An image acquisition method using a lens array acquires a plurality of basic images having different parallaxes with respect to the position of each primary lens using a continuous array of primary lenses. An image acquisition method using a lens array has a simple implementation of an optical system, and has an advantage of providing a continuous image for a plurality of viewpoints during reproduction with one image acquisition. However, the above-described image acquisition method has a phenomenon in which the depth is reversed because the acquisition of the base image is performed through the lens array at the point of time in which the base image is acquired. This has a different disadvantage.

Stereo cameras consist of two very similar characteristics. Stereo cameras are spaced parallel to each other like human eyes. The image obtained by the stereo camera is obtained with the left image and the right image. Left and right images have a large parallax for objects near the camera, while their depth information has a small value.

The stereo camera method can obtain the depth map 112 of the object using devices readily available under normal lighting. The left and right images extract a depth map 112 through a stereo matching process. Stereo matching is achieved by using the features of the objects extracted from the left and right images. The extracted feature may be a large dispersion point or contour information of an object in left and right images. The correlation of the extracted features is obtained by stereo matching. The distance to the object points can be calculated from the parallax of the corresponding points obtained by this stereo matching.

The method for obtaining disparity information is to find a corresponding point of another image satisfying a cost function in one image, and there are a method of pixel unit, block unit, object base, and feature point unit. That is, in a method of finding a corresponding point by comparing the left and right images, the unit may be set in units of pixels, blocks, objects, or feature points. However, the method of obtaining the depth map 112 using the stereo camera has a disadvantage in that it takes a long time by extracting the features of the left and right images. In addition, when there are similarities in the extracted features of the left and right images, the stereo matching process is not clear.

Unlike the above-described method, the active camera method acquires an image using one camera. In particular, as an embodiment of the present invention, the image input unit 100 may be a three-dimensional active camera (hereinafter referred to as an active depth camera) 110 to which depth-sensing processing function is added to the two-dimensional video.

The principle of the active depth camera 110 is to generate a beam of regular intervals within the field of view to obtain the depth map 112, and to detect the beam reflected by the three-dimensional object 500, the depth map 112 and the three-dimensional The 2D image 111 is obtained. The active sensor provides a black and white video stream for the distance area that matches the resulting two-dimensional image 111. In addition, since the active depth camera 110 may acquire the depth map 112 together with the pixel value of the image obtained from the 3D object 500, the active depth camera 110 may have a gray level value corresponding to distance 3. The depth map 112 for the dimensional object 500 may be extracted.

The gray level of the depth map 112 may determine a predetermined interval as one gray level. The depth map 112 may limit generation of too many sectioning images 201 according to too many gray levels by determining the same gray level at regular intervals. In addition, the determination of the predetermined range as one gray level may be for determining an object having a same sense of depth as one gray level. In addition, the gray level depends on the distance between the three-dimensional object 500 and the active depth camera 110, the value can be set arbitrarily. That is, as the distance between the 3D object 500 and the active depth camera 110 increases, the gray level may be set larger or vice versa.

Accordingly, the active depth camera 110 may obtain the 2D image 111 corresponding to the depth map 112 obtained from the active sensor. And all of this is done in real time. The active depth camera 110 method can provide a high depth resolution in a real environment. The method using the active depth camera 110 has an advantage of obtaining the depth map 112 in real time as in the 2D image 111.

The sectioning image processor 200 and the element image generator 300 perform image processing in the 3D integrated image system. Sectioning of the 2D image 111 and generation of the element image for reproducing the image acquired from the 3D object 500 as a 3D stereoscopic image are performed.

According to an embodiment of the present invention, the sectioning and the element image generation may be a method of creating and executing a program as a part that can be processed by a program on a computer. Therefore, sectioning and element image generation have advantages of fast data processing and efficient processing. Details of sectioning and element image generation will be described later.

The image reproducing unit 400 reproduces the 3D image by using the generated element image. Unlike image reproduction in a general integrated image method, a 3D image is reproduced by projecting onto a lens array 430 using a projector 410 to use an element image. A detailed description of the image reproduction will be described in detail with reference to FIG. 7.

As shown in FIG. 2, the image acquisition according to an embodiment of the present invention obtains the 2D image 111 and the depth map 112 from the 3D object 500 using the active depth camera 110. .

Referring to FIG. 2, papers in which A, B, and C are written in different colors are placed at different distances from the active depth camera 110 as the three-dimensional object 500. The active depth camera 110 acquires a 2D image 111 of the 3D object 500 and generates beams at regular intervals from a light source embedded therein. The active depth camera 110 detects a beam in which the generated beam is reflected by each paper and returned. The active depth camera 110 obtains the depth map 112 by mapping the same time to the same gray level in consideration of the time when the beam is detected.

Accordingly, the active depth camera 110 may acquire a two-dimensional image 111 and at the same time obtain a depth map 112 from a three-dimensional object 500 called paper of different colors and distances A, B, and C. .

3 is a diagram for describing a configuration of a sectioning image processor according to an exemplary embodiment of the present invention.

As shown in FIG. 3, the sectioning image processor 200 according to an embodiment of the present invention includes a first processor 210 and a second processor 220.

The first processor 210 extracts pixel position information corresponding to a predetermined gray level from the depth map 112. For example, when there are three pixels having a gray level of 1, the first processor 210 stores position information of three pixels.

The second processor 220 generates the sectioning image 201 by extracting the pixel value of the corresponding 2D image 111 by using the position information of the pixels extracted by the first processor 210. For example, the second processor 220 extracts pixel values of three pixels corresponding to position information of pixels having a gray level of 1 in the 2D image 111. The second processor 220 generates one sectioning image 201 using position information and pixel values of three pixels in the 2D image 111. The second processor 220 performs this process at each gray level. That is, the second processor 220 may separate one two-dimensional image 111 into a plurality of sectioning images 201 corresponding to each gray level.

4 is a view for explaining a sectioning image processing method according to an embodiment of the present invention.

As shown in FIG. 4, the sectioning image 201 processing according to an embodiment of the present invention uses a depth map 112 to convert one two-dimensional image 111 into a plurality of sectioning images 201. To separate.

Referring to FIG. 4, the black and white depth map 112 shows different gray levels depending on the distance. Referring to FIG. 2, A has the lowest gray level because it is the farthest. Also, the closest C has the highest gray level because it is closest, and B has a medium gray level. The sectioning image processor 200 extracts location information of pixels corresponding to each gray level.

The sectioning image processor 200 separates the 2D image 111 for each pixel having the same gray level. That is, one sectioning image 201 may be an image having a value only for pixels corresponding to the same gray level, and the remaining pixel values have a zero value. Therefore, the sectioning image processor 200 may generate three sectioning images 201 of an A-only image, a B-only image, and a C-only image as one 2D image 111.

4 is a simple experiment by way of example, it is apparent to those skilled in the art that the number or spacing of gray levels may vary according to the three-dimensional object 500.

5 is a view for explaining a method of generating an element image array according to an exemplary embodiment of the present invention.

As illustrated in FIG. 5, the element image array 330 may be generated by a plurality of sectioning images 201, a pinhole array 320, and a pickup plane 310.

One element image is generated by combining a plurality of sectioning images 201. Referring to FIG. 5, the plurality of sectioning images 201 are arranged at regular intervals.

Each sectioning image 201 is projected onto one pinhole 321 of the pinhole array 320 to be imaged on the pick-up surface 310. Each projected sectioning image 201 is imaged on the pick-up surface 310 to produce one element image. One element image may be generated by combining images of a plurality of sectioning images 201 through one pinhole 321.

Each element image may be combined according to an image forming position to generate an element image array 330. The element image array 330 may be generated by combining one element image, and the element image array 330 is an image projected by the projector 410 to reproduce a 3D image.

The pickup surface 310 refers to a plane on which one element image is generated, in which a plurality of sectioning images 201 are formed. The pickup surface 310 may be a plane that generates the element image array 330 according to a position where the element image is formed.

The pinhole array 320 projects the sectioning image 201 into a collection of a plurality of pinholes 321 to be combined at the pickup surface 310. As described above, one pinhole 321 may generate one element image.

Accordingly, the element image is generated by the plurality of sectioning images 201 projected onto one pinhole 321, and the element image array 330 is formed by forming a plurality of element images on the pickup surface 310.

6A and 6B illustrate a principle of generating an element image according to an exemplary embodiment of the present invention.

6A and 6B, the element image is generated by combining the sectioning image 201 projected through the pinhole 321.

The sectioning images 201a and d are projected onto the respective pinholes 321 to form an image, and the sectioning images 201d closer to the pickup surface 310 than the pinholes 321 are formed without being inverted. In addition, the sectioning image 201a formed through the pinhole 321, that is, closer to the pinhole 321 than the pickup surface 310, is inverted and formed.

In the sectioning image 201, the size of an image formed on the pick-up surface 310 is determined according to the distance from the pinhole 321. The image formed on the pick-up surface 310 becomes smaller as the distance from the pinhole 321 increases. This is because, like the sectioning image 201a that is inverted, the sectioning image 201d that is not inverted does not pass through the pinhole 321, but the size of an image formed by the distance to the pinhole 321 is determined in the same principle. .

As described above, when each sectioning image 201 is projected onto one pinhole 321 to be imaged on the pick-up surface 310, one element image may be generated.

7 is a diagram for describing a configuration of an image reproducing unit according to an exemplary embodiment of the present invention.

As illustrated in FIG. 7, the image reproducing unit 400 may include an element image display apparatus, an imaging lens 420, and a lens array 430.

The image reproducing unit 400 is an integrated image reproducing system for reproducing the generated element image array 330 as a 3D image. Referring to FIG. 7, the element image display apparatus may be a projector 410.

In the 3D image, the element image array 330 is projected from the projector 410 and reproduced in space through the lens array 430.

The imaging lens 420 may be disposed in front of the projector 410 to adjust the size and sharpness of the element image array 330 to be projected in accordance with the lens array 430.

At this time, one element image to be projected is matched with one lenslet of the lens array 430. The element image is projected onto one lenslet of the lens array 430, and each projected element image is reproduced as one three-dimensional image.

Matching one element image to one lenslet is intended to allow the reproduced image to be reproduced in space without distortion.

The 3D image at this time is an image corresponding to the image pickup object of the 2D image 111 in which the element image is generated. The image reproducing unit 400 is similar to the principle of reproducing a 3D image in space by projecting the image onto the lens array 430 in the 3D integrated image method.

8 is an exemplary diagram for describing a 3D integrated image method using an element image according to an exemplary embodiment of the present invention.

Referring to FIG. 8, the 3D reproduced image may sense various stereoscopic feelings according to various angles of the active depth camera 110 when capturing the fixed 3D object 500.

The right image 601 reproduces the fixed three-dimensional object 500 and the two-dimensional image 111 in which the active depth camera 110 is located on the right side of the front image 600 and photographed. It was expressed as being far away.

The left image 602 reproduces the fixed three-dimensional object 500 and the two-dimensional image 111 where the active depth camera 110 is positioned on the left side of the front image 600 and photographed. Expressed as being close.

The lower image 603 reproduces the fixed 3D object 500 and the 2D image 111 in which the active depth camera 110 is positioned below the front image 600 and photographed. Expressed as being close.

The upper image 604 reproduces the fixed three-dimensional object 500 and the two-dimensional image 111 in which the active depth camera 110 is positioned above the front image 600 and photographed. It was expressed as being far away.

That is, the right, left, bottom, and top images 601, 602, 603, and 604 transmit different stereoscopic feelings due to different angles of looking at the 3D object 500 compared to the front image 600. Accordingly, it can be seen that the present invention provides a three-dimensional three-dimensional effect even when the fixed three-dimensional object 500 is photographed by reflecting the distance from the object through the depth map 112.
