Hereinafter, the present invention will be described in more detail with reference to preferred examples. However, these examples are intended to illustrate the present invention in more detail, it will be apparent to those skilled in the art that the scope of the present invention is not limited thereby. The present invention will be described in detail with reference to the accompanying drawings based on the preferred embodiments of the present invention for clarifying the solution of the problem to be solved by the present invention, and a detailed description of known functions or configurations related to the present invention and If it is judged that various other matters may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a view of color information for each line of sight scanned by a light source into an observer's observation range.

The color information has a value between 0 and 255 of each of the R, G, and B values in the RGB set, and a total of 256 * 256 * 256 different colors can be designated as the RGB set. For example, 0/0/0 is black, 255/255/255 is white, and 255/0/0 is red. Meanwhile, the brightness information in the RGB color space may be expressed by increasing or decreasing the values of R, G, and B in the same ratio.

Each cell shown in FIG. 1 corresponds to one light source unit, and one light source unit combines R, G, and B light sources to generate one pixel of a color image.

2 is a block diagram of a 3D image display apparatus using a laser according to an embodiment of the present invention.

Referring to FIG. 2, the 3D image display apparatus according to the present exemplary embodiment includes a database unit 210, an optical scan data determiner 220, a light source controller 230, and a light source unit 240.

The database unit 210 stores the acquired image according to the viewpoint of viewing the image.

The optical scan data determiner 220 determines the optical scan data to be scanned by the light source 240 according to the image stored in the database 210.

On the other hand, it is also possible to generate a single laser-generated image by arranging the color information to be scanned for each light source 240 relative to each other, and then scan the generated laser image to a lens or a convex mirror to scan a variety of eyes simultaneously. Do. The laser generation image may be implemented as a computer program that converts the gaze information provided for each light source unit 240 into a laser generation image.

Therefore, one light source 240 may scan all of the points of the image in the observation area observed by the observer, or may separate two or more points of the image according to the refractive index of the laser and scan the points in the observation area.

The light source controller 230 controls the light source unit 240 so that the light source unit 240 can scan a laser beam to the observer's eye. The light source controller 230 may be implemented using MEMS (Microelectromechanical Systems) for controlling the position of the light source 240.

The light source unit 240 generates and scans the optical scan data. The light source unit 240 provides a color or contrast of a pixel to be provided for each observer's line of sight using a laser in accordance with the direction of the line of sight. The arrangement of the light source units 240 to scan the laser light may be configured in various physical forms including a plane or a sphere, depending on the implementation method.

On the other hand, the light source unit 240 is configured as a three primary color laser light source for displaying a full color image. The three primary laser light sources are preferably composed of R (red), G (green), and B (blue) light sources.

3 is a conceptual diagram of a 3D image display apparatus using a laser according to an embodiment of the present invention.

Referring to FIG. 3, a plurality of light source units 240 form an array, and each light source unit corresponds to one pixel. Each light source 240 scans the laser in both eyes of the human, but the right and left eye images are preferably scanned differently according to binocular parallax.

In particular, in order to make the 3D stereoscopic image more realistic, it may be desirable to allow different images to be viewed when the position of the human eye is above, middle, or below.

To this end, the database unit 210 stores images acquired from above, middle, and bottom, and the optical scan data determiner 220 scans the light source 240 to scan according to the images obtained from above, middle, and bottom. The data will be determined. The light source unit 240 scans a laser beam into the human eye according to the optical scan data determined by the optical scan data determiner 220. At this time, since the image scanned in the eyes of the person located in the middle, up and down, slightly different, the color pixel scanned by the light source unit 240 may also be different.

The light source unit 240 sequentially scans the laser to the eyes positioned above, the middle and the bottom, but should be synchronized with the other light source unit 240 so that several pixels of the same image can reach the eye at the same time.

4 is a conceptual diagram of a 3D image display apparatus using a laser according to another embodiment of the present invention.

Referring to FIG. 4 as in FIG. 3, a plurality of light source units 240 form an array, and each light source unit corresponds to one pixel. Each light source 240 scans the laser in both eyes of the human, but the right and left eye images are preferably scanned differently according to binocular parallax.

Meanwhile, in order to make the 3D stereoscopic image more realistic, it may be desirable to allow different images to be viewed when the position of the human eye is on the left, the middle, and the right. To this end, the database unit 210 stores the images obtained from the left, the center, and the right.

The optical scan data determiner 220 determines the optical scan data to be scanned by the light source unit 240 according to the images obtained from the left, the middle, and the right. The light source unit 240 scans a laser beam into the human eye according to the optical scan data determined by the optical scan data determiner 220. In this case, since the image scanned by the eyes of the person located on the left, the center, and the right is slightly different, the color pixels scanned by the light source unit 240 may also be different.

FIG. 5 illustrates an image stored differently in the database unit 210 according to the position of the human eye as shown in FIGS. 3 and 4.

In addition to the upper, middle, and lower images in FIG. 3 and the left, middle, and right images in FIG. 4, the images existing therebetween may be estimated by an interpolation method.

As shown in FIG. 5, color information of a laser scanned by the light source unit 240 may also vary according to an image stored differently according to the position of the camera.

Meanwhile, in the 3D image display apparatus using the laser according to another embodiment of the present invention, each light source unit 240 scans an image that varies depending on the position of the camera for each unit region in which the image is displayed, so that each light source unit 240 The images of the left and right eyes may not need to be considered separately.

6 is a conceptual diagram illustrating that some laser beams scanned by the light source unit may form an image in an eye at a different distance from the light source unit.

Referring to FIG. 6, it can be seen that an image may be formed not only on a certain distance from the light source but also on another distance.

Meanwhile, gazes starting from the same light source and having the same direction may be treated as one gaze. When the observer's position is outside of the object to be observed, the gazes of the eyes that are started from the same light source and have the same direction have the same color or contrast information, so they are treated as a single gaze information. You can.

In addition, the optical scan data generated by the optical scan data determiner 220 may be grouped into ones obtained from the same light source so that the light source 240 generates a laser light source which is actually scanned.

FIG. 7 illustrates an optical apparatus for refracting a laser to scan a laser in a range of observation areas when scanning a laser from a light source unit.

As an example, the concave lens is illustrated in FIG. 7, but is not limited thereto, and may be configured by a combination of various lenses. In addition, any device that refracts the laser to a particular area within a range of areas is possible.

In addition, as another example of an apparatus for scanning a laser, a method of scanning while changing the direction of a laser gun arranged for each light source using a mechanical device such as MEMS at a high speed is possible.

Since the refractive index of the laser can vary with frequency or wavelength, it may be possible to have a constant refractive index by placing the filter in front of the optical device. In this case, a monochrome image will be injected into the human eye.

FIG. 8 illustrates a method of acquiring an image of an object using an image acquisition device such as a camera from various viewpoints.

The image will change slightly depending on the position of the image acquisition device, that is, the position of the eye of the observer. The light source 240 stores the data in the database 210 to reflect the scanned image. An example of a stored image is shown in FIG. 5.

In the image acquisition device illustrated in FIG. 8, the eyes of an actual observer are positioned, and color information or contrast information for each line of sight is generated and stored in the database unit 210 according to an observation position within a range where the observer's eyes may be located. desirable.

Observation gaze information viewed by an image acquisition apparatus may be generated by generating a stereoscopic information of an object to be observed by a camera or a 3D scanner or by recording stereoscopic information of a designed product into a computer file. According to another embodiment, the observation gaze information is collected from images photographed at various positions of the observation object, and the observation gaze information of the observation position at which the photographing is not taken may include observation gaze information generated from an image photographed at a nearby location. Based on the mathematical interpolation can be generated approximately.

In operation 910, the 3D image display apparatus determines light source data to be scanned by each of a plurality of light sources constituting the light source array.

In this case, the light source data may be color information or contrast information for each observer's gaze. In addition, the image at the observation position existing on the path of the light source laser scanned from the light sources is formed by using the light source lasers from the plurality of light sources passing through the observation position, thereby reducing the amount of light source data. have.

The light source data may be determined based on other images acquired according to the viewpoint of the observer looking at the image in order to display more realistically.

However, according to the observer's viewpoint, the image of the viewpoint which is not acquired may be estimated and generated from the acquired image.
