1 is a block diagram of a multi-image control system according to an embodiment of the present invention.

Referring to FIG. 1, a multi-image control system according to an exemplary embodiment of the present invention includes an image divider 110 for dividing an image source into a plurality of image layers, and a mapping unit for mapping the plurality of image layers onto a three-dimensional space. 120, a warping processor 140 for warping the plurality of image layers to correspond to the curved surface in the three-dimensional space, a blending processor 150 for blending an overlapping region between the plurality of image layers, and The controller 130 may be configured to control the plurality of projectors 200 so that the plurality of image layers mapped in association with the timeline are projected on the 3D space.

First, the image divider 110 may divide an image source into a plurality of image layers. The image source may be, for example, image data constituting a background which is one of stage apparatuses used for a musical, a theater stage, and the like.

The image divider 110 automatically divides an image source into a plurality of image layers according to a preset number, or automatically divides the number of projectors 200 connected to the multiple image control system and the number of image layers allocated to each projector 200. After the calculation, the image source may be divided into a plurality of image layers according to the calculated number.

The mapping unit 120 may map the plurality of divided image layers on the 3D space. The three-dimensional space may be, for example, a stage on which musicals or plays are performed and may include any object having a volume and installed on the screen and the stage.

The mapping unit 120 defines a virtual projection surface for projecting a plurality of image layers and performs auto-calibration to perform mapping so that each image layer can be projected to an accurate point in three-dimensional space. can do.

The mapping unit 120 may map a plurality of image layers on a three-dimensional space using, for example, a camera tracking method.

The mapping unit 120 may set the 3D coordinates of the projection surface of the image data photographed by the camera by extracting information about a focal length, a motion, a view angle, etc. of the camera which actually photographs the 3D space. A plurality of image layers may be mapped to correspond to the set three-dimensional coordinates.

The mapping unit 120 may adjust at least one of positions, tilts, and sizes of the plurality of image layers to match the space to be mapped. For example, the mapping unit 120 may adjust at least one of a position, an inclination, and a size of the plurality of image layers to match the projection surface by using coordinates of the projection surface calculated through a camera tracking method.

The warping processor 140 may warp the image source or the plurality of image layers to correspond to the curved surface in the 3D space. The warping unit may perform a warping process of converting an image layer to correspond to an environment such as a bending angle of the curved surface by reducing or expanding a portion of the image layer so that the image projected on the curved surface in the 3D space is not distorted or distorted. .

The warping processor 140 may apply, for example, a screen adjustment and a partial image compression method in units of pixels or grids.

The blending processor 150 may blend the overlapping areas between the plurality of image layers. When a plurality of divided image layers are projected on a three-dimensional space, two image layers overlap each other in an overlapping area, so that brightness becomes brighter and appears to be brighter than the surroundings. The blending processing unit 150 may remove the drooping of the overlapping region by adjusting the brightness and contrast of the overlapping region.

The controller 130 may control the plurality of projectors 200 such that the plurality of image layers mapped in association with the timeline are projected on the 3D space.

The controller 130 may control the plurality of image projectors to be projected by controlling the plurality of projectors 200 arranged around the 3D space. The plurality of projectors 200 may project at least one image layer, and the number of image layers projected by each projector 200 may be set differently.

The controller 130 may control the plurality of projectors 200 to project an image layer in association with the timeline. The timeline may mean a time axis variable that is arbitrarily set. For example, the timeline may be a cue sheet used for a musical, a play, a broadcast, or the like.

A cue sheet is a table that arranges various cues according to a time table when making a play, a radio or a television program. In one embodiment of the present invention, an action cue used as a basis for a scene change in a musical or a play, etc. The table summarized according to the time table will be described as an example.

The controller 130 may control each projector 200 according to the cue sheet, and the projection time of each image layer may be independently controlled.

The controller 130 may control at least one of the lighting device and the sound device in association with the timeline. The lighting device and the sound device may be one of stage devices used in a musical, a play, and the like, and the controller 130 may control at least one of the lighting device and the sound device in association with the cue sheet.

2 is a conceptual diagram illustrating the operation of the controller 130 according to an embodiment of the present invention.

There are six projectors arranged around a three-dimensional space, and each projector is set to project at least one image layer.

Each image layer is independently controlled according to an action cue, and is configured to additionally control a lighting device and a sound device.

3 is a diagram illustrating a projector projection area in a three-dimensional space according to an embodiment of the present invention, and FIG. 4 is a diagram for describing a three-dimensional space in which a plurality of layers are projected according to an embodiment of the present invention.

Referring to FIG. 3, a three-dimensional space according to an embodiment of the present invention may include an object of a rectangular parallelepiped having an arbitrary volume in the center of an open space formed of four surfaces.

Each projector is arranged to have a constant projection angle around a three-dimensional space, and is set to project an image layer onto a four-sided or cuboid object.

Referring to FIG. 4, a plurality of image layers are projected on a three-dimensional space to project an image source having a three-dimensional effect. Each image layer is warped and blended, and is mapped by a camera tracking method to be projected at an accurate position in three-dimensional space.

The term '~ part' used in the present embodiment refers to software or a hardware component such as a field-programmable gate array (FPGA) or an ASIC, and '~ part' performs certain roles. However, '~' is not meant to be limited to software or hardware. '~ Portion' may be configured to be in an addressable storage medium or may be configured to play one or more processors. Thus, as an example, '~' means components such as software components, object-oriented software components, class components, and task components, and processes, functions, properties, procedures, and the like. Subroutines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functionality provided within the components and the 'parts' may be combined into a smaller number of components and the 'parts' or further separated into additional components and the 'parts'. In addition, the components and '~' may be implemented to play one or more CPUs in the device or secure multimedia card.
