BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-position presenting object, a position recognizing device, and a position recognizing method suitable for an object position recognizing mechanism for recognizing an existing position of an arbitrary object in an image processing system or the like. About. Specifically, a plurality of light sources having different blinking patterns are attached to a specific surface of an arbitrary object that can be imaged, so that the position of the light source can be easily specified, and the reference surface of the object is image-processed from the position of the light source.

Images of virtual bodies such as monsters and weapons are displayed in three dimensions. Then, when the observer wears glasses with a liquid crystal shutter and stands in the projection space, it is as if he were at the same place as the virtual object displayed on each display device.

Further, a weapon that an observer holds in a virtual space is imaged by a camera, and image processing is performed so that a virtual body reacts according to the movement of the weapon. This allows the observer to slip back in time to the primitive era thousands of years ago, and perform dinosaur extermination, etc., as if playing a game.

According to the conventional method of recognizing an object, when an image processing system attempts to recognize an object such as a weapon held by an observer in a real space, the method is not effective. The background image including the object is captured, the outline of the object is extracted, and the reference pattern stored in advance and the outline pattern of the object are compared.

Therefore, when only the object is recognized by the image processing system and an attempt is made to synthesize a virtual body image or the like with the object in the virtual space, the amount of calculation for pattern recognition of the image processing system increases. , The load on the arithmetic unit becomes heavy.

If a conventional pattern recognition method is applied as it is when constructing a synthesizing apparatus, it is difficult to easily recognize an object by an image processing system. There is a problem that image processing for recognizing the game becomes complicated or the amount of calculation at that time increases, leading to an increase in the cost of a game device or the like.

Accordingly, the present invention has been made in view of the above-mentioned problems, and has an object for presenting a self-position presenting object in which the position of an arbitrary object that can be imaged can be easily recognized by an image processing system.

According to the self-position presenting object according to the present invention, a plurality of light sources attached to a specific surface of an arbitrary object are controlled to blink by the control means so as to have different blinking patterns. When the object is imaged by a special photographing device such as a device, the position of the light source can be easily specified as compared with the case where the lighting patterns of the plurality of light sources are controlled to be non-blinking. Therefore, the position of the object can be easily recognized by the image processing system from the position of the light source.

An image capture unit 43 is connected to the interface 42. Upon receiving a control command from the CPU 45, a predetermined capture process for acquiring image data of a blinking pattern input from the panning CCD device 23 is performed. The image data of this blinking pattern is expressed as a change in luminance corresponding to the passage of time. An image processing unit 44 as a calculating means is connected to the image capturing unit 43,
Regarding the image data on which the predetermined image processing has been performed, the synchronization deviation of the blinking pattern is corrected, or the reference plane to which the observer belongs is obtained.

The position coordinates of the two light emitting diodes LED1 to LED4 are known, and the position coordinates are (x1, y1), (x2, y2),
(X3, y3) and (x4, y4).

Therefore, the above-mentioned reference plane in the real space can be obtained by calculating a conversion matrix projected onto the mounting positions of the four light emitting diodes LED1 to LED4. Here, the point (xi, yi, 0) on the plane of the real space is moved by a certain translation / rotational motion, and the point projected on the image coordinate system by the perspective transformation is represented by (Xi, Yi).

By connecting 4), the reference plane in the real space shown in FIG. 10 is recognized.

Specifically, on the arrangement pattern shown in FIG. 11, when the moving image pickup direction is the Y axis and the direction orthogonal to the Y axis is the X axis, the image processing unit 44 sets the same direction as the moving image pickup direction. Alternatively, the luminance signal values are added in the opposite direction. When the added value is plotted on the X axis, four positions where the luminance signal value plotted on the X axis is maximum are detected, and the X coordinate values X1 and X corresponding to the four positions are detected.
2, X3 and X4 are determined. Further, when the acquired image is scanned in the Y direction on the arrangement pattern, among the plurality of luminescent points arranged in the Y direction, the luminescent spot position that first emits light has a Y coordinate value Y1 corresponding to the X coordinate value. , Y2, Y3, Y4
Is required.

Here, the position coordinates of the four light emitting diodes LED1 to LED4 in the real space are defined as wi (i = 1 to 4), and the position coordinates wi of the four light emitting diodes LED1 to LED4 on the camera coordinate system. Assuming that the expression vector is Ci, the position coordinates of the four light-emitting diodes LED1 to LED4 on the LCD screen are Pi, the rotation matrix of the panning CCD device 23 is R, and the movement vector is T, the following equation (3) is obtained.
That is, Ci = R · wi + T (3) where Ci = Pi · ki (ki is a scalar). Therefore, the normal CCD imaging device 25
Of the rotation matrix R and its movement vector T,
Using this as a parameter, coordinate conversion between the real space and the virtual space can be easily performed, so that a character image can be synthesized on a reference plane in the virtual space.

Next, the operation of the game apparatus 100 will be described with respect to the method of recognizing the position of the self-position presenting object according to the present invention. In this example, four light emitting diodes LED1 to LED4 having different blinking patterns are mounted on a predetermined surface of a reference surface setting bracelet 1 that can be imaged, and the light emitting diodes LED1 to LED4 are imaged so as to flow in a predetermined imaging direction. Then, the brightness information of the light-emitting diodes LED1 to LED4 captured here is subjected to image processing to obtain four bright spot positions, and an external image to which the observer belongs is placed on a reference plane connecting the bright spot positions in the virtual space. ,
It is assumed that the image of the 3D polygon 10 is three-dimensionally combined.

For example, the observer wears the special glasstron 2 shown in FIG. 5 on the head. First, in step A1 of the flowchart shown in FIG. 12, in order to set an arbitrary reference plane in the real space to which the observer belongs, the observer, for example, sets the reference plane on the left arm so that the plate portion 11 faces upward. The bracelet 1 for use. Thereafter, the power switch SW shown in FIG. 2 is turned on, and a predetermined voltage is supplied from the blinking control circuit 13 to the four light emitting diodes LED1 to LED4 to blink in a predetermined blinking pattern.

In this example, a clock signal C having a predetermined frequency
LK1 is supplied to the light emitting diode LED1 through the resistor R, and a clock signal CLK2 obtained by dividing the clock signal CLK1 by １ ／ is supplied to the light emitting diode LE1 through the resistor R.
D2, the clock signal CLK3 obtained by dividing the frequency of CLK1 by 1/3 is supplied to the light emitting diode LED through the resistor R.
The clock signal CLK4 obtained by dividing the frequency of CLK1 by 1/4 is supplied to the light emitting diode LED4 through the resistor R.
Supplied to

Next, in step A2, a reference plane in real space is photographed using the ordinary CCD image pickup device 25, and a stereo image is displayed on the LCD 26 and the LCD 27. On the other hand, the panning CCD device 23 is used to pan and photograph a reference plane in real space. For example, 3D polygon 1
Since the four light emitting diodes LED1 to LED4 attached to the position where the image of 0 is to be synthesized are blinked so that the blinking patterns are different, the blinking pattern is imaged so as to flow in a predetermined imaging direction.

Thereafter, in step A3, image processing is performed to recognize an arbitrarily set reference plane in the real space to which the observer belongs. In the image processing unit 44, for example, a subroutine shown in FIG. 13 is called, and a video capture process is executed in step B1. Then, in step B2, the light emitting diodes LED1 to LED4 at the four corners are recognized. Specifically, the blinking pattern of the luminance signal by the four light emitting diodes LED1 to LED4 captured by the panning CCD device 23 is converted into a spatial arrangement pattern forming an XY plane including the four bright points P1 to P4. You.

Thereafter, the arrangement pattern is scanned, and
At least the position coordinates (X1,
Y1), (X2, Y2), (X3, Y3), (X4, Y
4) is calculated, and the above-described expressions (1) and (2) are calculated, and the mounting positions of the four light emitting diodes LED1 to LED4 in the real space and the position coordinates (X1, Y) of the four points of the image processing system.
1), (X2, Y2), (X3, Y3), (X4, Y
4) is obtained, and a reference plane is obtained by connecting these four points. Then, in step B3, the image processing unit 44 performs an arithmetic process based on the above equation (3).
The positional relationship between the panning CCD device 23 and the reference plane is detected.

Thereafter, the process returns to step A4 of the main routine of FIG. 12 to superimpose and synthesize the image of the 3D polygon 10 on the reference plane of the virtual space. At this time, in the special glasstron 2 worn by the observer, one of the stereo images obtained by synthesizing the external world image in the real space and the image of the 3D polygon 10 by the LCD 26 is guided to the right eyeball of the observer. The other stereo image obtained by synthesizing the external world image in the real space by the LCD 27 and the image of the 3D polygon 10 is guided to the left eyeball of the observer.

Therefore, although the 3D polygon 10 does not appear on the reference plane in the real space shown in FIG.
In the virtual space shown in FIG.
