Description

  The present invention relates to an illuminating device that irradiates irradiation light so as to cover a surface of a controlled device having an arbitrary shape.

  Conventionally, as described in Non-Patent Documents 1 and 2 below, as an illuminating device that irradiates light of an arbitrary shape, a filter called a gobo or a mask is installed in a projection device, and the projection device The projection part from which the irradiation light is emitted is shielded. Thereby, the irradiation light which passed the filter will be in the state cut out to the specific shape. Specifically, in a conventional illumination system, a filter (gobo or the like) cut out in a base shape composed of circles, triangles, squares, and the like is attached to a projection device to shape the outline of irradiation light.

  In addition, in a conventional illumination system, when it is desired to irradiate only the object to be irradiated, the projection position of the irradiation light emitted from the projection device is adjusted to the position of the object to be irradiated, and then roughly adjusted by the aperture function and zoom function of the projection device. The operation of matching the contour of the irradiated light with the shape of the irradiated object is performed.

  Further, conventionally, there is an illumination system that performs a space effect by using a projector, which is a projection device, instead of a lighting fixture (light). The lighting fixture used for this lighting system is also called a moving projector. This moving projector emits image light as irradiation light. For this reason, the shape and color of irradiation light can be freely set and changed as a moving image.

  However, even with this illumination system, when shaping the illumination light, a technique is used to roughly match the contour of the illumination light to the shape of the object to be illuminated, using the base shape, as with conventional illumination systems. Has been.

  Further, conventionally, a technique described in Patent Document 1 below is known as a stereoscopic display device that can effectively express the surface texture of an object in a stereoscopic model.

  However, in the above-described conventional illumination system, although the outline of the irradiation light can be changed according to the shape of the irradiated object, it is based on the outline of the irradiation light by a filter composed of circles, triangles, squares, etc. Although it is possible to roughly match the shape of the irradiated light with the contour of the irradiated object, it is difficult to accurately match the shape of the irradiated light with the contour of the irradiated object. That is, in the conventional illumination system, it is difficult to change the contour of the irradiation light in accordance with an object to be irradiated having an arbitrary shape.

  Then, this invention is proposed in view of the situation mentioned above, and it aims at providing the illuminating device which can coat the irradiation object of arbitrary shapes with irradiation light with high precision.

And a second coating correction unit that corrects the contour of the corrected coating light.

  According to the present invention, the contour of the coating light in the irradiated light is cut in accordance with the shape of the irradiated object, and further, the coating light is changed according to the positional relationship between the origin position of the irradiated object and the irradiated light projection means. Since the contour is corrected, the irradiated object can be coated with the irradiated light with high accuracy based on the shape of the irradiated object and the positional relationship between the irradiated object and the irradiated light projection unit.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The present invention is applied to a coating illumination apparatus including an illumination control apparatus 1 and an irradiation light projection unit 2 configured as shown in FIG. This coating illumination apparatus projects irradiated light toward an irradiated object 20 having an arbitrary shape, so that the irradiated object 20 is coated with the irradiated light 20 in a single color as shown in FIG. Is to be observed. Moreover, the coating illumination apparatus may coat the irradiated object 20 with not only single color irradiation light but also multiple colors or video irradiation light.

  Normally, when monochromatic irradiation light is emitted from the projector over the entire irradiation light projection range, irradiation light is irradiated in addition to the irradiation object 20 and a shadow is formed behind the irradiation object 20 as shown in FIG. End up. On the other hand, as shown in FIG. 2, the coating illumination device projects monochromatic irradiation light only on the surface of the irradiated object 20, and projects background color irradiation light on the background of the irradiated object 20. Thus, the irradiated object 20 is coated with the monochromatic irradiation light. In the following description, the irradiation light for coating the irradiated object 20 as shown in FIG. 2 is referred to as “coating light”, and the irradiation light that is the background of the irradiated object 20 is referred to as “background light”. .

  The irradiated object 20 is a three-dimensional object having an arbitrary shape as shown in FIG. As shown in FIG. 4B, the irradiated object 20 is reproduced three-dimensionally by computer graphic technology, and shape data in all directions is analyzed. Further, the irradiated object 20 may be reproduced three-dimensionally from a captured image of the irradiated object 20 by image sensing technology. This shape data is supplied to the illumination control device 1 and used for correction processing in a first coding correction unit 12 and a second coding correction unit 13 described later.

  As will be described later, in order to coat the object to be irradiated 20 with the irradiation light, the coating illumination apparatus performs a distortion correction process on the irradiation light signal and outputs the irradiation light from the irradiation light projection unit 2. Therefore, the irradiated object 20 is not particularly limited, and may be a concavo-convex object or a space constituted by a uniform plane (or curved surface). However, in order to improve the reproducibility of the color of the irradiation light projected from the irradiation light projection unit 2, the surface of the irradiated object 20 is preferably processed with a screen material or the like.

  The irradiation light projection unit 2 includes a projector that receives the irradiation light signal transmitted from the illumination control device 1 and emits irradiation light composed of coating light and background light.

  The illumination control device 1 includes an irradiation light generation unit 11, a first coating correction unit 12, and a second coating correction unit 13. In addition, although the illumination control apparatus 1 shown in FIG. 1 is comprised by the hardware by the computer provided with CPU, ROM, RAM, a storage apparatus, etc., in FIG. 1, it divides | segments for every functional block for convenience, Give an explanation.

  The irradiation light generation unit 11 functions as an irradiation light signal input unit that inputs an irradiation light signal. The irradiation light generation unit 11 may receive an irradiation light signal from an external personal computer, or may generate a single color irradiation light signal by designating the color of the single color light. The irradiation light signal is generated as a planar image.

  This irradiation light signal is, for example, a monochrome image signal in the entire irradiation light projection range when monochromatic illumination light is used as coating light as shown in FIG. The irradiation light generation unit 11 is a video signal in which the entire irradiation light projection range is a pattern image or video even when the irradiation light that is a pattern image or video of multiple colors is used as coating light. . The irradiation light signal input or generated by the irradiation light generation unit 11 is supplied to the first coating correction unit 12 and the second coating correction unit 13.

  The first coating correction unit 12 and the second coating correction unit 13 are supplied from the irradiation light generation unit 11 so as to coat the irradiated object 20 with the irradiation light when the irradiation target object 20 is irradiated with the irradiation light. The irradiated light signal is corrected. The first coating correction unit 12 and the second coating correction unit 13 correct the irradiation light signal so that the contour of the coating light included in the irradiation light matches the contour of the irradiated object 20.

  The first coating correction unit 12 corrects the irradiation light signal so as to cut the contour of the coating light included in the irradiation light in accordance with the shape of the irradiated object 20. Thus, the first coating correction unit 12 performs the cutting process on the coating light irradiation range so that the coating light is projected only on the irradiated object 20 and the background light is projected on the area other than the irradiated object 20.

  As shown in FIG. 5A, the first coating correction unit 12 receives a planar image 100 created by the irradiation light generation unit 11. Next, the first coating correction unit 12 inputs the shape data 20 ′ of the irradiated object 20 as coordinate parameters as shown in FIG. 5B, and the planar image 100 is input to the shape data 20 ′ of the irradiated object 20. Perform pasting mapping process. This mapping processing calculates which part of the illuminated object 20 each pixel of the planar image 100 is projected when the illuminated object 20 is viewed from the user's viewpoint position. By this mapping process, the first coating correction unit 12 determines the correspondence between each pixel of the planar image 100 and the coordinates on the irradiated object 20.

  As a result, the planar image 100 becomes a three-dimensional image 100 ′ whose coordinates are converted by the shape data 20 ′ as shown in FIG. Here, in the planar image 100, the image portion outside the shape data 20 'is excluded, and only the image portion that can be mapped on the shape data 20' is left. That is, the portion that does not become the coating light becomes the background light.

  The three-dimensional image 100 ′ is processed by the first coating correction unit 12 to be projected onto the display surface of the projector that is the irradiation light projection unit 2 as shown in FIG. This process calculates which part of the irradiated object 20 the projection surface of the irradiated light projecting unit 2 is projected when the coating light is projected onto the irradiated object 20 from the installation position of the irradiated light projecting unit 2. And this process is a correspondence between the projection surface of the irradiation light projection unit 2 and the coordinates of the irradiated object 20, and the correspondence between the coordinates of the irradiated object 20 obtained by the above mapping process and each pixel of the planar image 100. From the relationship, the correspondence between the projection surface of the irradiation light projection unit 2 and each pixel of the planar image 100 is obtained. Accordingly, the first coating correction unit 12 converts the planar image 100 to reconstruct the planar image 100 ″ shown in FIG. This process will be described in more detail with reference to FIGS.

  By performing such a mapping process, the first coating correction unit 12 maps the planar image 100 supplied from the irradiation light generation unit 11 only on the irradiation object 20 having an arbitrary shape, and the irradiation object 20 It can be set as the video which is not mapped to other parts. The image subjected to the mapping process becomes a video signal for projecting the coating light onto the irradiated object 20 by the first coating correction unit 12. The background light with respect to the coating light becomes a video signal that becomes a video portion other than the video portion corresponding to the coating light. The first coating correction unit 12 supplies the second coating correction unit 13 with an irradiation light signal including a video signal of coating light projected on the irradiated object 20 and a video signal of background light.

  Here, when the center axis (origin position) of the irradiation object 20 coincides with the center axis of the projection range of the irradiation light projection unit 2, the irradiation light signal corrected by the mapping process described above is used. The irradiated object 20 can be coated with coating light with high accuracy. However, when the positional relationship between the origin position of the irradiated object 20 and the central axis of the projection range of the irradiated light projection unit 2 is not directly opposed, the first coating correction unit 12 alone has high accuracy with the irradiated object 20. Cannot be corrected enough to light the coating. That is, when the optical axis of the irradiation light projection unit 2 is deviated from the origin position of the irradiated object 20, it is necessary to correct the irradiation light signal using the position of the irradiation light projection unit 2 as a parameter.

  For this purpose, the coating illumination apparatus further performs a correction process on the irradiation light signal by the second coating correction unit 13 according to the relationship between the origin position of the irradiated object 20 and the position of the irradiation light projection unit 2. Do. In this correction processing, the video display parameters are changed by performing parallel movement conversion and rotational movement conversion on the video display parameters necessary for video creation. In this case, the image display parameter is changed by converting the image display parameter into an asymmetric value in the vertical and horizontal directions along the irradiation light projection range. As a result, even when the irradiation light is projected from the irradiation light projection unit 2 onto the irradiated object 20 from an arbitrary direction, the coating illumination device projects the coating light only on the irradiated object 20 with high accuracy. Further, the contour of the coating light is corrected.

  Specifically, the second coating correction unit 13 inputs in advance the position of the irradiated object 20 and the position of the irradiated light projection unit 2, and uses the posture parameters of the irradiated object 20 with respect to the irradiated light projection unit 2. A certain correction parameter is acquired. And the 2nd coating correction | amendment part 13 performs parallel displacement conversion and rotational displacement conversion based on a correction parameter.

  In addition to the positional relationship between the irradiation light projection unit 2 and the object 20 to be irradiated, the coating illumination apparatus performs the performance and observation of the irradiation light projection unit 2 such as the projection field angle of the irradiation light projection unit 2 and the optical axis shift amount. The irradiation light signal may be corrected in consideration of the position of the person. Specifically, the coating illumination device inputs a preset observer position, the shape of the irradiated object 20, and the relative position and orientation of the irradiated light projection unit 2 and the irradiated object 20. Then, a correction table is created as a correction parameter that can be coated with high accuracy when the irradiation light is projected onto the irradiated object 20. This correction table is a correspondence map between a flat projection surface and a mesh model of the projection surface of the irradiated object 20 having an arbitrary shape. This correspondence map is used to perform coordinate conversion according to the correction table and convert a video signal for flat display into an output video signal for display in an arbitrary shape for each pixel of the irradiation light signal.

  Further, such a correction table is prepared for each position of the observer, the shape of the irradiated object 20, the relative position and posture of the irradiated light projection unit 2 and the irradiated object 20, and the second coating. Correction may be performed by selecting the correction unit 13.

  Further, when the coating illumination device projects the image coating light onto the irradiated object 20 as described above, the coating illumination device performs image distortion correction processing using the observer's viewpoint position as a correction parameter, as shown in FIG. It is desirable to include a third coating correction unit 21 to perform.

  When there is a viewpoint position of the irradiation object 20 recommended in advance, the third coating correction unit 21 has a correction table for correcting the image distortion when the irradiation object 20 is observed from the viewpoint position. Stored. Then, when the irradiation light signal is supplied from the second coating correction unit 13, the third coating correction unit 21 performs coordinate conversion on each pixel of the irradiation light signal according to the correction table so that an image without image distortion is obtained. To do. Accordingly, the coating illumination device can distort the image light so that the image projected without being distorted when the image projected on the irradiated object 20 is viewed from the viewpoint position of the observer.

  In addition, when a value obtained by measuring the observer's viewpoint position is input, the third coating correction unit 21 may calculate a viewpoint position parameter from the measured value. Thereby, the 3rd coating correction | amendment part 21 can produce | generate the coating light which coats the to-be-irradiated object 20 so that it can watch without distortion from a viewpoint position, even after the movement of a viewpoint position.

  As described above, according to the coating illumination apparatus to which the present invention is applied, the irradiation light signal is corrected based on the shape of the irradiated object 20, and the positional relationship between the irradiated light projection unit 2 and the irradiated object 20. Since the irradiation light signal is corrected based on the above, only the irradiated object 20 can be irradiated with the coating light with high accuracy.

  Further, according to this coating illumination device, it is possible to project an image that has been corrected in advance so as to eliminate distortion in the irradiated object 20 that is configured in an uneven shape including furniture. For example, the vehicle design can be reviewed by projecting a car image on the irradiated object 20 in the shape of a car. It can also be used for arbitrarily shaped advertising signs and decorations.

  Next, in the above-described coating illumination device, it will be described that even if an image is projected onto the irradiation object 20 having an arbitrary shape as shown in FIG. 6 or 7, the image can be seen without distortion.

  For example, as shown in FIG. 8, let us consider a flat object 30 that is spaced apart from the user U by a distance L and is inclined with respect to the user U as the irradiation object 20 having an arbitrary shape. The flat object 30 is viewed from the viewpoint position P1 of the user U at a viewing angle θ1. The distance from the point P2 on the flat object 30 intersecting the user U's visual field center to the user U is a distance L1.

  In the positional relationship between the viewpoint position P1 and the point P2 on the flat object 30, as shown in FIG. 9A, a lattice-like planar image 100 (coating light) shown in FIG. Consider the case of viewing on the flat object 30 via the viewing image plane 40U. In this case, when the same image is displayed on the flat object 30 as the flat image 100 shown in FIG. 9B is displayed on the image surface 40U, each coordinate on the image surface 40U and each image on the flat object 30 are displayed. It is necessary to obtain the correspondence with the coordinates. 9A, the points b1, b2, b3, b4, and b5 on the image plane 40U correspond to the points a1, a2, a3, a4, and a5 on the flat object 30. ing. Therefore, the images displayed at the points a1, a2, a3, a4, and a5 on the flat object 30 are visually recognized by the user U as points b1, b2, b3, b4, and b5 on the image plane 40U.

  As shown in FIG. 10, the point P2 where the line of sight of the user U intersects with the flat object 30 and the projection position P3 of the irradiation light projection unit 2 are a distance L2. Further, the irradiation light projection unit 2 projects the projection light within a predetermined projection angle of view θ2.

  In this case, the positional relationship between the image plane 40P of the irradiation light projection unit 2 and the flat object 30 is such that the points a1, a2, a3, a4, and a5 on the flat object 30 are as shown in FIG. It corresponds to points c1, c2, c3, c4, and c5 on 40P. That is, points on a straight line obtained by extending the points c1, c2, c3, c4, and c5 on the image plane 40P from the projection position P3 of the irradiation light projection unit 2 are points a1, a2, a3, a4 of the flat object 30. a5.

  From such a relationship between the viewpoint position P1 and the viewing angle θ1 of the user U, the position of the flat object 30, the projection position P3 of the irradiation light projection unit 2, and the projection field angle θ2, the irradiation light projection shown in FIG. When an image is projected onto the points c1, c2, c3, c4, and c5 on the image plane 40P in the unit 2, the image is projected onto the points a1, a2, a3, a4, and a5 on the flat object 30. As a result, the points a1, a2, a3, a4, and a5 on the flat object 30 are visually recognized as the points b1, b2, b3, b4, and b5 on the video screen 40U in FIG. Therefore, in order for the user U to visually recognize the planar image 100, the irradiation light projection unit 2 sets the coordinates on the flat object 30 corresponding to the coordinates on the image surface 40U and the coordinates on the image surface 40P. Based on the corresponding relationship with each coordinate on the corresponding flat object 30, it is necessary to project a distorted planar image 100 '' as shown in FIG.

  In order to realize such a projection operation of the coating light, the illumination control device 1 includes a viewpoint position indicating the viewpoint position P1 of the user U, a viewpoint position / posture parameter indicating the line-of-sight direction, and the user U's position as shown in FIG. A viewing angle parameter indicating the viewing angle θ1 is acquired. These user U parameters define the video plane 40U described above.

  Further, the shape data of the flat object 30 onto which the coating light emitted from the irradiation light projection unit 2 is projected is acquired. This shape data is, for example, CAD data. Here, the viewpoint position and orientation parameter is a numerical value that defines a position on the X, Y, and Z axes and a rotation angle around the axis in a three-dimensional coordinate space. This viewpoint position and orientation parameter uniquely determines the distance L1 between the viewpoint position P1 and the flat object 30 and the attitude of the flat object 30 with respect to the viewpoint position P1. The shape data of the flat object 30 is defined as a shape region in a three-dimensional coordinate space based on electronic data created by CAD or the like. This shape data uniquely determines the shape of the flat object 30 viewed from the viewpoint position P1. The shape data of the flat object 30 and the parameters of the user U define the correspondence between the coordinates of the video plane 40U and the coordinates on the flat object 30.

  Further, as shown in FIG. 10, the illumination light projection unit 2 is installed, and the illumination control device 1 is a position indicating the projection position P3 of the illumination light projection unit 2 and the optical axis direction of the illumination light projection unit 2. A projection field angle parameter indicating the orientation parameter and the projection field angle θ2 of the irradiation light projection unit 2 is acquired. The position / orientation parameter and the projection angle-of-view parameter of the irradiation light projection unit 2 represent the image plane 40P that the irradiation light projection unit 2 projects onto the flat object 30. When the image plane 40P is determined, it is determined on which coordinate of the flat object 30 the coating light projected from the irradiation light projection unit 2 is projected via the image plane 40P. That is, the position / orientation parameters and projection angle-of-view parameters of the irradiation light projection unit 2 and the position / orientation parameters and shape data of the flat object 30 are determined by the flat object 30 covered with the coating light emitted from the irradiation light projection unit 2. The range of is uniquely determined. When the irradiation light projection unit 2 is a projector, the projection position P3 is defined by the back focus and the driving angle, and the projection angle of view θ2 is calculated from the horizontal and vertical projection ranges at a fixed distance from the projection position P3.

  Then, the illumination control device 1 includes a straight line connecting the pixels (a1, a2, a3, a4, a5) of the coating light displayed on the flat object 30 and the projection position P3 of the irradiation light projection unit 2, and an image plane 40P. A plane image 100 ″ is formed by arranging pixels at intersections (c1, c2, c3, c4, c5) with the plane image 100 ″, and the plane image 100 ″ is projected onto the flat object 30. The points c1, c2, c3, c4, c5 on the image plane 40P, the points a1, a2, a3, a4, a5 on the flat object 30 and the points b1, b2, b3, b4, b5 on the image plane 40U. In this way, the user U can visually recognize an image without distortion.

  Similarly, even if the irradiated object 20 is not shaped like the flat object 30 but is a dome type, it can be coated without distortion, and the irradiated object 20 can be visually recognized by the user U. Assume that the irradiated object 20 is a dome-shaped object 30 as shown in FIG. 12A, and the user U visually recognizes the grid-like coating light as shown in FIG. 12B. In this case, the user U views the points a1, a2, a3, a4, and a5 on the dome-shaped object 30 on the extension line of the points b1, b2, b3, b4, and b5 on the video screen 40U. On the other hand, the irradiation light projection unit 2 projects the projection light onto the image plane 40P as shown in FIG. The projection light that has passed through the points c1, c2, c3, c4, and c5 on the image plane 40P is projected onto the points a1, a2, a3, a4, and a5 on the dome-shaped object 30, and the image shown in FIG. It is visually recognized as points b1, b2, b3, b4, b5 on the surface 40U. Therefore, the irradiation light projection unit 2 projects the distorted planar image 100 ″ as shown in FIG. 13B on the image plane 40 </ b> P. On the other hand, the user U can visually recognize a flat image 100 without distortion as shown in FIG.

  Next, what added a new structure with respect to the coating illumination apparatus mentioned above is demonstrated.

"Irradiation pattern"
In the coating illumination apparatus, the irradiation light generation unit 11 stores an irradiation light pattern storage unit that stores a plurality of irradiation light signals of the irradiation light pattern in advance, and any irradiation light pattern stored in the irradiation light pattern storage unit. You may provide the irradiation light pattern selection part which selects and reads an irradiation light signal. The irradiation light pattern storage unit includes a storage (not shown), and the irradiation light pattern selection unit includes an operation interface for selecting any one of the irradiation light patterns.

  As the plurality of irradiation light patterns, an irradiation light pattern for coating the irradiation object 20 with a single color coating light as shown in FIG. 3, and an irradiation object 20 with a predetermined pattern of coating light as shown in FIG. And an irradiation light pattern for coating the irradiated object 20 with image coating light as shown in FIG. 6B.

  The irradiation light generation unit 11 in such a coating illumination apparatus includes an operation interface for selecting an irradiation light pattern by an administrator or an observer of the coating illumination apparatus, for example, and any irradiation light based on the operation of the operation interface. Select a pattern. Then, the irradiation light generation unit 11 supplies the selected irradiation light pattern to the first coating correction unit 12 and the second coating correction unit 13.

  Thereafter, the first coating correction unit 12 and the second coating correction unit 13 correct the irradiation light signal of the irradiation light pattern selected by the irradiation light pattern selection unit. The irradiation light projection unit 2 can project the corrected irradiation light signal and coat the irradiated object 20 with the coating light of the irradiation light pattern selected by the irradiation light pattern selection unit.

  Such a coating illumination device can easily and instantaneously switch the irradiation light pattern to be used by preparing a plurality of irradiation light patterns in advance.

"Leakage light suppression"
Further, as shown in FIG. 14, the illumination control device 1 in this coating illumination device may include a leakage light suppression unit 14 that suppresses leakage light that leaks from the irradiated object 20 and is projected behind.

  Here, the above-described coating illumination device projects coating light so as to coat the object 20 having an arbitrary shape. Therefore, if it is going to coat to the edge of the irradiated object 20 with high accuracy by the coating light, the coating light goes out of the irradiated object 20 and is projected behind as leakage light. This leakage light is generated due to minute deviations in the position and orientation parameters of the irradiation light projection unit 2 and the irradiated object 20 and individual differences of the irradiation light projection unit 2 (projector). However, since this parameter and device accuracy are limited, it is very difficult to correct the video signal so that the irradiated object 20 is completely coated so as not to generate leakage light.

  Therefore, this coating illumination device does not cause leakage light by processing the video signal corrected by the first coating correction unit 12 and the second coating correction unit 13, and the generated leakage light is not conspicuous. Like that.

  The leakage light suppression unit 14 is supplied with the video signal corrected by the first coating correction unit 12 and the second coating correction unit 13. The leakage light suppression unit 14 performs processing for suppressing leakage light on the supplied video signal and supplies the processed image signal to the irradiation light projection unit 2.

  The leakage light suppression process of the leakage light suppression unit 14 includes correcting the irradiation light signal so that the coating light is not projected onto an area of the irradiated object 20 that is not larger than a preset size. Specifically, as shown in FIG. 15, in the human-type irradiated object 20, the coating light is projected onto a region 20a larger than a predetermined size, but the hand portion and the foot portion having a predetermined size or less. The coating light is not projected onto the region 20b. Thereby, the coating illumination apparatus suppresses that the coating light projected from the irradiation light projection unit 2 toward the irradiated object 20 leaks from the irradiated object 20 and is projected onto the background of the irradiated object 20. be able to. In FIG. 15, as a user interface, the monitor device 3 that allows the user to confirm how the coating light is actually projected is provided, and the projection state 3 a is displayed on the monitor device 3.

  Further, as shown in FIG. 16, the leakage light suppression unit 14 may change the illumination effect of the coating light projected onto the contour portion 20 c having a predetermined width in the irradiated object 20. For example, the coating portion light is not projected onto the contour portion 20c.

  Thereby, the illumination control device 1 is conspicuous that the coating light projected from the irradiation light projection unit 2 toward the irradiated object 20 leaks from the irradiated object 20 and is projected onto the background of the irradiated object 20. To lose. In this way, the coating illumination apparatus increases the probability of leaking light when the projection area of the coating light is set on a thin part or a fine part of the irradiated object 20, so that the area 20b having a predetermined size or less is set. Exclude from the projection area of the coating light.

  Furthermore, as shown in FIG. 17, the leakage light suppression unit 14 may gradually change the illumination effect of the coating light from the inside toward the outside in the predetermined width of the contour portion 20d. Also in this manner, the illumination control apparatus 1 indicates that the coating light projected from the irradiation light projection unit 2 toward the irradiated object 20 leaks from the irradiated object 20 and is projected onto the background of the irradiated object 20. It can be inconspicuous.

  Specifically, illumination effects to be changed in the contour portion 20d include illuminance, luminance, luminous intensity, luminous flux, color temperature, color rendering, and the like. Then, the leakage light suppression unit 14 changes the illumination effect of the coating light in the contour portion 20d so that the leakage light leaked from the irradiated object 20 is not noticeable even when projected onto the background. For example, the leakage light suppression unit 14 makes the leakage light inconspicuous by reducing the illuminance of the coating light at the contour portion 20 d of the irradiated object 20. Further, the leakage light suppression unit 14 can gradually reduce the leakage light by gradually reducing the projection area of the coating light by increasing the width of the contour portion 20d where the illuminance is set to zero. Further, the leakage light suppressing unit 14 may increase the width of the contour portion 20d until the leakage light disappears. Note that it is desirable that the contour portion 20d set to reduce leakage light is determined according to the reduction area of the projection region of the coating light.

  Furthermore, as shown in FIG. 18, the leakage light suppression unit 14 may correct the video signal so that the coating light is not projected onto the acute angle portion of the star-shaped irradiated object 20. In this case, the leakage light suppressing unit 14 processes so as to round off an acute angle portion of the coating light. Thereby, the acute angle portion becomes a region 20f where the coating light is not projected. In this way, leakage light is likely to occur at an acute angle portion, whereas the coating light is rounded to suppress generation of leakage light.

  Furthermore, the leakage light suppression unit 14 may vibrate the coating light projected by the irradiation light projection unit 2 with a predetermined width. Thereby, even if the coating light which is not projected on the to-be-irradiated object 20 has generate | occur | produced as leakage light, the illumination intensity visually recognized from the user U can be made low by vibration. Therefore, according to the leakage light suppressing unit 14, the coating light projected from the irradiation light projecting unit 2 toward the irradiated object 20 leaks from the irradiated object and is projected onto the background of the irradiated object. Can be eliminated.

  Furthermore, as a configuration for suppressing the leakage light, as shown in FIG. 19, in addition to the irradiation light projection unit 2 that projects the coating light onto the irradiation object 20, the leakage light leaks to the back surface 20 ′ of the irradiation object 20. You may provide irradiation light projection part 2 'which projects the background light which suppresses light. As shown in FIG. 20, the irradiation light projection unit 2 ′ is installed so that the projection range 52 is not included in the irradiated object 20. Thereby, even if the projection range 51 of the coating light of the irradiation light projection part 2 shifts | deviates from the to-be-irradiated object 20, and leakage light generate | occur | produces back 20 ', leakage light can be made not conspicuous by background light.

  The light projected onto the back surface 20 'may be an illumination effect (illuminance, luminance, luminous intensity, luminous flux, color temperature, color rendering) set so as to make leakage light inconspicuous. For example, the irradiation light projection unit 2 ′ irradiates the back surface 20 ′ with white light or the like. Accordingly, the leakage light can be made inconspicuous by utilizing the property that the color becomes white light by overlapping the colors.

  By projecting the background light onto the back surface 20 ′ in this way, as shown in FIG. 21, the object 20 to be irradiated is coated with the coating light, and the back surface 20 ′ is illuminated with the projection range 52 of the background light. You can also produce. In the example shown in FIG. 21, the illumination effect of the back surface 20 'of each irradiated object 20 is performed using two irradiation light projection units 2'. In the example shown in FIG. 21, as shown in FIG. 22, an illumination effect is performed on each irradiated object 20 using the two irradiated light projection units 2, whereas the irradiated object 20 Each irradiation object 20 can be coated using two irradiation light projection units 2 for each.

"Reflector"
Furthermore, this coating illumination apparatus can arrange a reflecting mirror on the optical axis between the irradiation light projection part 2 and the to-be-irradiated object 20, and can adjust the projection distance of irradiation light long, or irradiation light The projection unit 2 can also be arranged at a position where it cannot be seen. Furthermore, even when the irradiation light projection unit 2 has a compact configuration, it is possible to coat the irradiation object 20 having a relatively large size by increasing the projection distance of the irradiation light by the reflecting mirror.

3D image
Furthermore, this coating illumination apparatus may supply an irradiation light signal for displaying a stereoscopic image to the irradiation light projection unit 2 to observe the coating light projected on the irradiated object 20 as a stereoscopic image. The coating illumination device generates an irradiation light signal for the right eye and an irradiation light signal for the left eye, which are given parallax with each other, by the irradiation light generation unit 11, and the first illumination light signal is generated for each irradiation light signal. The correction processing by the coating correction unit 12, the second coating correction unit 13, and the third coating correction unit 21 is performed.

  In this case, the coating illumination apparatus causes the observer to wear polarized glasses with different polarization directions of the image light transmitted through the right eye and the left eye, and to parallax from the irradiation light projection unit 2 in a polarization method or a time division method. And a plurality of types of irradiation light having different polarization directions are emitted. When a stereoscopic image is displayed on the irradiated object 20 by the polarization method, a material that maintains the polarization direction of the image light is used as the surface material of the irradiated object 20, and the two light exit ports of the irradiated light projection unit 2 are used. The right-eye irradiation light and the left-eye irradiation light having different polarization directions are emitted. Further, when a stereoscopic image is displayed on the irradiated object 20 in a time-sharing manner, the right-eye irradiation light and the left-eye irradiation light are alternately emitted in a time-sharing manner from one light exit, and the right-eye irradiation is performed. The emission timing of the light and the irradiation light for the left eye is synchronized with the switching timing of the right eye and the left eye shutter of the liquid crystal shutter glasses.

  Thereby, according to this coating illumination apparatus, coating light is projected only on the irradiation object 20 of arbitrary shapes with high accuracy, and the stereoscopic image on the irradiation object 20 is allowed to be observed without distortion. Can do.

"Change of irradiation light projection range and coating range"
The coating illumination apparatus may change the irradiation light projection range of the irradiation light projection unit 2 by adjusting the angle of view of the irradiation light projection unit 2. Such a coating illumination device can coat the irradiated object 20 with the coating light in the irradiation light projection range in which the angle of view of the irradiation light projection unit 2 is adjusted.

  Further, the coating illumination device may specify a spatial region in which the coating is to be performed in the irradiated object 20. In such a coating lighting apparatus, the coating light is projected onto a portion to be coated in the irradiated object 20 and the background light is projected onto a portion not to be coated in the irradiated object 20. In this way, a signal for distinguishing between a portion coated with coating light and a portion not coated in the irradiated object 20 is supplied in advance to the coating illumination apparatus. Then, the coating illumination apparatus uses the irradiation light signal supplied from the irradiation light generation unit 11 to the first coating correction unit 12 as a coating light only for a portion to be coated in the irradiated object 20, and the other as a background light. The irradiation light signal is corrected and supplied to the first coating correction unit 12.

  Further, the portion that can be coated and the portion that cannot be coated may be changed by an observer. For example, the area to be coated of the irradiated object 20 is 3 from the origin position (base point) specified by the shape parameter of the irradiated object 20, assuming that the entire irradiated object 20 is coated as 100%. Can be set as a percentage of the dimension.

"Coating for multiple irradiated objects 20"
Furthermore, when selecting the part which can coat with respect to several irradiated object 20, all the irradiated objects 20 may be coated similarly, and the part coated with respect to each irradiated object 20 is selected. May be specified. For example, when there are a plurality of irradiated objects 20 in the irradiation light projection range of the single irradiation light projection unit 2, a plurality of coating light projection areas are provided in the irradiation light projection range, Individual irradiated objects 20 can be coated. In this case, the first coating correction unit 12 needs to perform mapping processing on the shape data 20 ′ of the plurality of irradiated objects 20 on the single planar image 100.

  The coating illumination device may select individual irradiation light patterns for the plurality of irradiated objects 20. In such a coating illumination apparatus, an irradiation light pattern is assigned to each irradiated object 20 by the operation interface for selecting the irradiation light pattern. Then, the irradiation light generation unit 11 generates a planar image 100 including each selected irradiation light pattern corresponding to the approximate position of each irradiation object 20 with respect to the irradiation light projection unit 2, and the first coating correction unit 12, mapping processing is performed on the shape of each irradiated object 20 within the irradiation light projection range.

  Furthermore, the coating illumination device includes irradiated object identification means (such as a camera) for individually identifying the plurality of irradiated objects 20 in order to individually assign the irradiation light pattern to the plurality of irradiated objects 20. May be. Then, the coating illumination device designates one of the irradiation light patterns set in advance for each irradiated object 20 and coats with the irradiation light pattern. In addition, the coating illumination device detects the distance between the irradiation light projection unit 2 and the object to be irradiated 20 by a distance sensor, and based on the distance, the distance from the irradiation light projection unit 2 is within a predetermined range. The object 20 may be coated. Note that the distance between the irradiation light projection unit 2 and the object to be irradiated 20 can be detected by attaching a magnetic sensor to each fixed point.

"Shape change of irradiated object 20"
In the coating lighting device, the irradiated object 20 may be able to change its shape according to a preset shape pattern. The position of the irradiated object 20 is fixed.

  Such a coating illumination device includes a drive mechanism that changes the shape of the irradiated object 20 in accordance with an operation performed by an observer on an operation interface. In this coating illumination apparatus, the shape pattern of the irradiated object 20 that is changed by the drive mechanism is set in advance, and the shape parameter corresponding to the shape pattern of the irradiated object 20 is stored.

  When the shape pattern of the irradiated object 20 is changed by the drive mechanism, the coating illumination device calls the shape parameter of the shape pattern, and the first coating correction unit 12 emits the irradiation light as shown in FIG. Perform signal mapping. Thus, the coating illumination device stores the shape pattern of the irradiated object 20 in advance as a shape parameter, so that the first coating correction unit 12 can easily change the shape pattern of the irradiated object 20. Correction processing can be performed, and the shape can be coated with irradiation light.

  Furthermore, the coating illumination apparatus may follow the arbitrary shape change of the irradiated object 20 and perform the mapping process by the first coating correction unit 12. Such a coating illumination apparatus includes a detection unit such as a camera that detects that the shape of the irradiated object 20 is arbitrarily changed by an operation interface operated by an observer, and the contour (shape parameter) of the irradiated object 20. ) Is required.

  In such a coating illumination device, when the shape when the irradiated object 20 is viewed from the irradiation light projection unit 2 is updated by the contour detection unit, the first coating correction unit 12 performs the contour detection unit. The mapping process is performed so as to coat the irradiated object 20 having the contour (shape parameter) detected by the above.

  Thereby, the coating lighting apparatus can perform the mapping process by updating the shape parameter even when the irradiated object 20 changes to an arbitrary shape.

"Displaying Symbols"

The symbol insertion location designation means sets the symbol insertion location at a distance in the three-dimensional direction from the origin position (base point) designated by the shape parameter of the irradiated object 20.

  Unlike the above-described irradiation light pattern, such a coating illumination device can insert a symbol having a specified size at a specified location of irradiation light.

  Also, the coating lighting device can read and insert arbitrary symbols such as characters and designs. This coating illumination apparatus includes a symbol reading unit (for example, a scanner) that reads an arbitrary symbol such as a character or a design, and a symbol image conversion unit that converts the read symbol into an image composed of two colors such as black and white. . This coating illumination apparatus can cut and insert the read symbol into a part of the irradiation light that coats the irradiated object 20. This coating illumination apparatus can insert a handwritten character or design on a paper read by a scanner, or a hand-held image, for example.

  Furthermore, the coating lighting device includes a real-time symbol reading unit (for example, a tablet PC) that reads a handwritten character or design as an image composed of two colors in real time in order to update the cut design in real time. The coating illumination device cuts and inserts a handwritten symbol into a part of the irradiation light that coats the irradiated object 20. This makes it possible to insert characters and designs written on the spot and review them.
