Edge blending system based on multi-beam projector, and Edge blending method based on multi-beam projector

The present invention relates to an edge blending system and an edge blending method based on a multi-beam projector. More specifically, the boundary between projector screens generated when expressing content on a large screen in an exhibition or exhibition space using multiple projectors. The present invention relates to a multi-beam projector-based edge blending system and an edge blending method for natural connection between projections when using a projector to solve the problem of overlapping projection projections.

In order to realize a large screen at an exhibition, a large screen is displayed by using two or more projectors instead of LCD for cost reasons. What happens in the use of such a beam projector is that there is overlap in the contact portion between the beam projects. To solve this problem, referring to FIG. 1, the beam projector edge blending is described. In other words, in order to express an extremely long image using the beam projector, it is necessary to connect several beam projectors. Therefore, the overlapping part of the beam projectors becomes brighter, indicating that the beam projectors are connected in multiple ways. This technique is called edge blending to reduce brightness and match colors to the brightness within the beam projector.

There is equipment that handles these functions in hardware, but if it is too expensive and the position of the beam projector is difficult to keep horizontal due to the situation of exhibition space, it is impossible to process overlapping parts of the image.

In other words, in order to remove such overlap, the equipment which blends the edges of the contact with hardware is used. However, since the equipment is quite expensive, it is not normally used. In addition, even if correction is made, the number of beam projectors is limited.

Can be easily deduced to the average expert in the field of < / RTI >

The content production module 20 performs the storage to the storage medium 50 by setting the number of screens for implementing the beam projector group and registering the content implemented for each screen number. That is, the number of screens to be represented by the group of beam projectors is set, and the content shown for each screen may be multimedia content such as an image, an image, a flash, 3D data, and sound. On the other hand, the beam projector group here is the render-to-texture beam projector 1 70-1 to the render-to-texture beam projector n (70-n: n is a natural number of two or more), "n" by the content production module 20 It is preferable that it is the number of screens to be set. In the present invention, the storage medium 50 may be formed as a main memory device or an auxiliary memory device in the system. In this case, the stored medium 50 is maintained and not deleted even when power is not supplied as a non-volatile memory (NVM). , A flash memory, a magnetic random access memory (MRAM), a phase-change random access memory (PRAM), a ferroelectric RAM (FRAM), or the like.

The content viewer module 30 implements the content registered on the screen divided by the number set by the content creation module 20 as the output medium 60 according to the multiple render-to-texture rendering method. When the content viewer module 30 completes the production of the content by the content production module 20, the content viewer module 30 displays the number of beam projectors set on the output medium 60 by using the multiple render-to-texture rendering method through the viewer. The area is divided so that the registered content is displayed on the screen.

More specifically, the content viewer module 30 according to the present invention uses a 3D rendering technique to process edge blending for the screen set by the content creation module 20, and renders to textures among the 3D rendering techniques. texture) technique, which uses the 3D engine to project the portion of the screen's camera onto the texture when rendering to the screen. To this end, in the present invention, as described above, the setting for the render-to-texture beam projector 1 (60-1) to the render-to-texture beam projector n (60-n: n is a natural number of 2 or more) is performed in the content creation module 20. Will be.

In general, the render-to-texture technique is used as shown in FIG. 3 to map a texture to an object to express an object to be expressed. That is, the present invention develops a render-to-texture technique to set multiple cameras as render-to-texture beam projectors 1 (60-1) to render-to-texture beam projectors n (60-n) to render multiple objects to multiple textures. We use the multiple render-to-texture technique to make two-to-texture and render it to a 3D object.

Multi-render-to-texture processing, on the other hand, uses a new technique that uses multiple cameras for render-to-texture rendering, using a single camera in the 3D rendering engine, with separate render-to-textures for each additional number of beamprojects. There is an advantage that can be set. Accordingly, as shown in FIG. 4, two render-to-texture cameras forming the first screen and the second screen may be generated, and two separate screens may be created and displayed on the screen in real time.

Accordingly, the blending manager module 40, which will be described later, is a boundary surface when several projectors, render-to-texture beam projector 1 70-1 to render-to-texture beam projector n (70-n: n is a natural number of 2 or more), are used. It is possible to provide a software technique that provides a natural connection in the edge region corresponding to.

The blending manager module 40 generates an edge control point (ECP) for an overlapping area on the screen implemented by the content viewer module 30, and automatically centers each edge control point (ECP). After performing the position shift with respect to the adjacent screen, and stores the position adjustment value on the storage medium (50).

That is, the blending manager module 40 generates at least one edge control point (ECP) for the overlapping portions on each screen and automatically fits the connection portions between the edges, as shown in FIG. 5, between the first screen and the second screen. In the edge area, two upper edge control points (ECP-1) and lower edge control points (ECP-2) are preferably formed in two. On the other hand, if necessary, the operator can manually move the control point of the edge to adjust the overlap naturally.

In addition, the braiding manager module 40 performs brightness adjustment on two screens which are moved based on the edge control point ECP, and then stores the brightness adjustment value on the storage medium 50. That is, the braiding manager module 40 adjusts the brightness corresponding to the brightness of the overlapping part of the screen through image processing after adjusting the overlapping part on the screen, and the brightness control value at this time is an external setting file. The service is executed by loading the stored value in real service.

The control screen implemented by the blending manager module 40 includes two multi-screens as shown in FIG. 6, in which the edge area is controlled in software by the blending manager module 40. By adding a control point on the boundary of the software, it controls the position, and selects an area on the overlapping portion to perform image processing to provide a natural software connection.

Referring to FIGS. 1 to 7, the content creation module 20 performs storage to the storage medium 50 by setting the number of screens to be implemented as the beam projector group and registering the contents to be implemented for each screen number (S11).

Here, the beam projector group may be configured as render-to-texture beam projector 1 60-1 to render-to-texture beam projector n (60-n: n is a natural number of 2 or more and the number of screens set in step S11).

After the step S12, the content viewer module 30 implements the content registered on the screen divided by the number set in the step S11 as the output medium 60 according to the multiple render-to-texture rendering method (S12).

After step S12, the blending manager module 40 generates an edge control point (ECP) for an overlapping area on the screen implemented in step S12, and then automatically sets each edge control point (ECP). After the position movement with respect to the adjacent screen with respect to the center, and stores the position adjustment value on the storage medium (50) (S13).

After the step S13, the braiding manager module 40 performs brightness adjustment on the two screens which are moved based on the edge control point ECP, and then stores the brightness adjustment value on the storage medium 50. (S14).
