Description

  The present invention is a mark unit that indicates a position on a screen with respect to a pointing device such as a game gun-type controller having an image pickup means, and is particularly detachable and compatible with various types of displays, and is inexpensive and convenient. It is related to a highly reliable mark unit.

  Conventionally, in shooting games, etc., by using a hardware that replicates a gun as a pointing device for inputting the coordinate position on the screen, by shooting the muzzle of the model at the target displayed on the screen, Development of a device to shoot the target is underway.

  The development of such a pointing device is very important in the current situation where interactive multimedia such as interactive television will be widely used in the future, and research is being actively promoted.

Here, as a known example of such a device, a technique disclosed in Patent Document 1 below has been proposed. That is, in the screen device instruction system in Patent Document 1, marks are displayed at four corners on the screen, and a part of the screen including the marks is captured by a gun-type controller having an imaging unit and captured by the image. By detecting the indicated position of the controller from the coordinates of the mark and the coordinate of the indicated position of the gun-type controller provided at the center of the image, and sending the detection data to the game machine, the indicated position of the gun-type controller is determined. It has a means to determine whether it corresponds with a target.
JP 2003-140832 A

  This type of position detection apparatus performs positioning of the image pickup apparatus using position information on the image plane of the four corner marks photographed by the image pickup apparatus, and therefore performs accurate position detection in consideration of projection distortion. In this case, information on the positions of the four corner marks specified on the display is always required. Note that the positions of the marks are not necessarily the four corners of the display as in Patent Document 1, but at least four marks are essential for detection accuracy.

  In such a conventional technique, when the aiming or pointing position of the imaging device is determined in the peripheral area of the display, the mark provided on the opposite side is out of the shooting range, and four marks can be projected on the image plane. As a result, the imaging apparatus cannot be positioned. Therefore, in order to make sure that these four marks are captured within the image plane range, the distance between the display and the imaging device needs to be sufficiently large so that the entire display can be seen.

  Therefore, as shown in FIG. 6, the present applicant has proposed a new mark in which each of the marks 0 to 3 is provided with three index line segments indicating the directions of other marks. These marks 0 to 3 are provided at the four corners of the display. As shown in FIG. 7, when two of the marks (for example, marks 0 and 1) are imaged, they are provided on the marks 0 and 1, respectively. The three index line segments are extended, and the positions of the two marks 2 and 3 that are not imaged are estimated from the intersections. Based on the positions of the two marks 2 and 3 estimated to be the positions of the two captured images 0 and 1, the coordinates of the four marks on the imaging screen W are calculated, and the display is performed based on the coordinates. The indicated position of the gun-type controller on the screen V (the center point 0 of the imaging screen W) is obtained.

  In addition, this mark is provided only in two places at the four corners of the display in advance, and the number of marks placed on the display is reduced by estimating the positions of the remaining two display corners from the imaging positions of the two marks. It can also be used for such methods.

  By the way, in the screen device indicating system shown in the above-mentioned patent document, as a mark provided on the screen for specifying the pointing device pointing position, a conventional method of providing a light source such as an infrared LED on the screen, and recursion A method of attaching a reflector such as a reflector is common.

  However, these two methods have the following problems. First, in the method of providing a light source on the screen, when using a pointing device, it is necessary to use a dedicated display device for the device, that is, a display device incorporating a light source for displaying a mark, or attach a light source to an existing display device. there were. However, a display device incorporating such a light source is very expensive, and even when a light source is attached, the wiring work is troublesome if the number of light sources is large, and the wiring itself becomes an obstacle when using the display device. Therefore, it was unsuitable as a household product. Furthermore, even if such wiring is omitted and battery driving is performed, there is a problem that user convenience is low from the viewpoint of battery life.

  On the other hand, since many conventional reflectors are mounted on the screen using an adhesive, it is difficult to remove them once they are mounted. Further, even when the reflection plate can be peeled off from the screen, the adhesive material may remain on the screen. In addition, the part where the reflector was not affixed on the screen was exposed to the outside, whereas the part that was affixed was covered with the reflector, so after peeling the adhesive, In some cases, the presence or absence of dirt is noticeable or the color unevenness occurs between the pasted part and the other part. As described above, the reflector using the conventional adhesive material is extremely inconvenient.

  In addition, when retrofitting a mark as shown in FIG. 6 above, it is necessary to adjust the position of each mark so that the index line segment provided on each mark always faces the direction of the other mark, Each mark can be easily moved, and after installation, it is necessary to be surely positioned on the display. However, as in the prior art, a mark using an adhesive material cannot be adjusted once it is placed on a display, and is not suitable for fixing a mark having an index line segment.

  Furthermore, recently, since displays with different aspect ratios such as 4: 3 and 16: 9 have been used, it is necessary to change the angle of the index line segment at each mark for each display having a different aspect ratio. In that respect, it is not appropriate to use a conventional technique in which one kind of mark is pasted on a display.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and its purpose is to set the position on the screen relative to a pointing device such as a game gun-type controller having imaging means. As an expression, it is possible to provide a mark unit that is detachable and compatible with various types of screens, and that is inexpensive and highly convenient.

  Another object of the present invention is to provide a mark unit that can easily adjust a mark position and can be used for displays having different aspect ratios when a mark including an index line segment is used.

  In order to achieve the above object, the mark unit according to claim 1 is a mark unit attached to a corner of a display, and the mark unit is composed of at least two orthogonal surfaces, and at least one of the orthogonal surfaces. The surface is characterized in that a pointing device recognition mark of a pointing device is provided on the surface.

Since it is possible, it is easy to attach and detach as compared with the case of providing a light source such as a conventional LED or the case of providing a reflecting plate, and thus is highly convenient.

The invention described in claim 2 is characterized in that, in the invention described in claim 1, a non-slip member is provided on the back of each orthogonal surface to prevent slippage between the display and the display.
In the invention according to claim 2 as described above, since the non-slip member made of, for example, rubber or urethane is provided on the back of each surface of the mark unit, the mark unit can be securely installed on the display. It can be carried out.

  According to a third aspect of the present invention, the pointing position recognition mark of the pointing device is provided on an outer surface of a plurality of the orthogonal surfaces in the invention according to the first or second aspect, and the pointing position recognition mark is a display According to the difference in aspect ratio, it is different from each other.

  In the invention according to claim 3 as described above, it is possible to select a recognition mark surface that matches the display and attach it to the screen according to the size of the display or the aspect ratio of the screen. Is expensive.

According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the indication position recognition mark unit is composed of three surfaces orthogonal to each other.
In the invention according to claim 4 as described above, since the mark unit has a very simple configuration of three orthogonal box shapes, various displays can be used regardless of the type and size of the display. It can be mounted on.

  According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, the orthogonal surfaces are integrally formed and folded through grooves provided in connection portions of the surfaces. It is characterized by being included.

  In the invention according to claim 5 as described above, each surface of the mark unit is integrally formed and is used by being bent through a groove provided in a connecting portion of each surface. Manufacture is facilitated, and each surface is flat when stored, so that space is not required and storage is facilitated.

  The invention according to claim 6 is the invention according to any one of claims 1 to 5, wherein the mark includes index line segments indicating directions of other marks provided at four corners of the display. And

  In the invention according to the sixth aspect as described above, by using the mark including the index line segment, the mark position can be easily adjusted, and it is possible to deal with displays having different aspect ratios.

  According to the present invention, the position on the screen is represented with respect to a pointing device such as a game gun-type controller having an image pickup means, which can be detachably adapted to various types of screens, and is inexpensive and convenient. A highly specific mark unit can be provided.

  Next, various modes for carrying out the present invention (hereinafter referred to as “embodiments”) will be specifically described with reference to the drawings.

[First Embodiment]
FIG. 1 is a perspective view (a) showing the configuration of the first embodiment of the mark unit according to the present invention and a front view (b) showing a state in which the mark unit is attached to the upper left and right corners of the display M.

  As shown in FIG. 2A, the mark unit 10 has a three-sided box shape in which three rectangular plates are orthogonal to each other, and includes a recognition mark surface 2, a display installation surface 3, and a side surface 4, respectively. The recognition mark surface 2 is positioned on the screen V side of the display M, the display installation surface 3 is positioned on the top of the display, and the side surface 4 is positioned on the side surface of the display M.

  The recognition mark surface 2 is provided with three index line segments 21, 22, and 23, each constituting a mark. These three index line segments 21, 22, and 23 are installed at the four corners of the display. This indicates the direction of the mark. That is, on the recognition mark surface 2, index line segments 21 and 22 parallel to the vertical and horizontal sides of the display M and an index line segment 23 coinciding with the diagonal line of the display M are represented. Further, a non-slip member 5 made of rubber, urethane or the like is provided on the back surface of the display installation surface 3 in order to ensure the attachment of the mark unit 10 when installing with various displays. The side surface 4 guides the left and right positions when the mark unit 10 is attached to the display M. That is, if the side surface 4 is attached to the side surface of the display M, the pair of left and right marks are positioned symmetrically.

  Next, attachment of the mark unit 10 having such a configuration to the display M will be described. First, with respect to the upper left and right corners of the display M, the recognition mark surface 2 is placed toward the screen V side so that the back surface of the mark surface 2 is in contact with the screen V. Then, the left and right positioning is performed by aligning the side surface 24 with the side surface S of the display M. In this case, since the mark unit 10 is positioned based on the recognition mark surface 25 and the side surface 24, the width and depth of the display M are not affected at all.

  The mark unit 10 of the present embodiment as described above has the following effects. That is, the mark unit 10 has a very simple configuration of a three-sided box shape with three rectangular plates orthogonal to each other, so it can be attached to various displays regardless of the type and size of the display. Is possible. Moreover, since it is the structure which attaches the recognition mark surface 2 and the side surface 4 together on the screen V side and the side surface S side of the display M, it can be attached and detached as compared with the case where a light source such as a conventional LED is provided or a reflector is provided. Because it is easy to use freely, it is highly convenient.

  Moreover, since it attaches on the basis of the recognition mark surface 2 as mentioned above, the mistake of an attachment direction, an attachment location, etc. can be prevented. Furthermore, since a non-slip member made of rubber, urethane or the like is provided on the back surface of the installation surface 3, the mark unit 10 can be reliably installed on the display M.

[Second Embodiment]
In the second embodiment, the configuration of the three surfaces including the recognition mark surface of the mark unit of the first embodiment is improved. FIG. 2 shows the second embodiment of the mark unit according to the present invention. It is a perspective view which shows the structure.

  As shown in FIG. 2, the mark unit 20 of the present embodiment has a three-sided box shape in which three rectangular plates are orthogonal to each other, and each plate has a difference in screen aspect ratio or screen size. Correspondingly, there are differences in size or configuration. That is, the mark unit 20 of this embodiment includes three recognition mark surfaces 11, 12, and 13 (hereinafter also simply referred to as “surfaces”), and the surface 11 is configured to correspond to an aspect ratio of 4: 3. The surface 12 is configured to correspond to an aspect ratio of 16: 9, and the surface 13 is configured to correspond to a large screen having an aspect ratio of 16: 9.

  That is, as shown in the first embodiment, the recognition mark surface of the present invention is composed of index line segments 21 and 22 parallel to the vertical and horizontal sides of the display M and an index line segment 23 coinciding with the diagonal line of the display M. Of these, as shown in FIG. 3, if the aspect ratios (4: 3 and 16: 9) of the screen are different, the positions of the index line segments that coincide with the diagonal line are different. Therefore, in this embodiment, the surface 11 is configured to correspond to an aspect ratio of 4: 3, and the surface 12 is configured to correspond to an aspect ratio of 16: 9.

  Further, even in the case of a display having the same aspect ratio, in the case of a so-called large screen, it may be difficult to recognize the mark by the imaging device of the pointing device with a normal mark. Therefore, in the present embodiment, the recognition mark surface 13 for a large screen is provided not only for the case where the aspect ratios are different as described above but also for the size of the screen. The direction of the index line segments 21c, 22c and 23c is the same as that of the index line segments 21b, 22b and 23b of the surface 13, but the length of each index line segment is large. It is configured to be longer than the index line segment of the surface 12 so as to correspond to the screen.

  When the recognition mark surfaces are provided on all surfaces as in the present embodiment, the display installation surface in the first embodiment must also play a role. Accordingly, the non-slip members 14a, 14b and 14c having the same configuration as that of the first embodiment are provided on all three back surfaces.

  In the mark unit of the present embodiment configured as described above, a recognition mark surface that matches the type of the display M is selected from the three types of marks according to the size of the display M and the aspect ratio of the screen. It can be attached with the screen side. Therefore, in the mark unit of the present embodiment, in addition to the first embodiment, it is possible to provide a replaceable mark unit corresponding to various types and sizes of screens.

[Third Embodiment]
The third embodiment is configured such that three surfaces of the mark unit of the first embodiment or the second embodiment can be assembled. FIG. 4 shows the configuration of the third embodiment of the mark unit according to the present invention. It is the front view (a) and enlarged perspective view (b) which show.

  As shown in FIG. 4A, the mark unit 30 of the present embodiment has one surface (here, the surface 11) of recognition mark surfaces 11, 12, and 13 having the same configuration as that of the second embodiment. Are connected integrally. Further, as shown in FIG. 4B, a fold line 31 in which a groove having a thinner plate thickness than that of the other portion is provided at the connection portion of these mark surfaces. Each surface of the mark unit 30 is configured such that the surfaces are orthogonal to each other via the fold line 31.

  Further, when the surfaces 11 and 13 of the mark unit 30 are bent through the fold line 31, the connecting members that connect the sides 12a and 13a in contact with each other in order to maintain the box shape of the three surfaces. 32 is provided. In addition, about the specific structure of this coupling member 32, as long as the orthogonal state of both can be maintained, it may be of any known aspect, for example, it may be locked by a concavity and convexity for fitting. I do not care.

  In the mark unit 30 of the present embodiment configured as described above, first, the three surfaces constituting the mark unit are bent so that the respective surfaces are orthogonal to each other via the folding line 31 to form a three-surface box shape. . At this time, the mark surface 121 and the mark surface 13 are coupled by fitting the coupling member 32 or the like. Next, as in the second embodiment, an aspect ratio or size matching the display M is selected, and the selected mark surface is attached to the display M with the screen V side.

  In the mark unit of the present embodiment as described above, each surface is integrally configured via the fold line 31, thereby facilitating the manufacture, and at the time of storage, each surface is made flat so that space It is easy to store.

[Other Embodiments]
The present invention is not limited to the embodiment as described above, and the following aspects can also be realized. In the above embodiment, the mark unit is configured by three orthogonal surfaces. However, the present invention is not limited to such a configuration, and, for example, as illustrated in FIG. Is also possible. In this case, since the mark unit 40 is formed only by the recognition mark surface 41 and the display installation surface 42, the degree of freedom for mounting the display M in the left-right direction due to the presence of the side plate can be increased. For example, when displaying an image with an aspect ratio of 4: 3 on a display M having a liquid crystal screen with an aspect ratio of 16: 9, as shown in FIG. However, it is very effective in such a case.

  Further, as shown in FIG. 5C, even when the speakers 43 are attached to the left and right of the display M, the mark unit 40 can be attached while avoiding the speakers 43. The method or procedure for attaching the mark unit 40 to the display is the same as in the above embodiment.

  Furthermore, in the present invention, as a mark having an index line segment, in addition to the radial mark as described above, a mark in which three index line segments are combined in a triangle shape, and only the apex of the triangle is arranged in a dot shape, It can also be used for a mark that is obtained by calculating an index line segment based on a captured point-like mark. Of course, it is possible to use a conventionally known simple circular or rectangular mark that does not include an index line segment, but in that case, all four marks are imaged to obtain their coordinates.
