Description

说明 Description of the invention (the description of the invention should state: the technical field to which the invention belongs, the prior art, the content, the embodiments, and the drawings) [Technical field to which the invention belongs] The present invention relates to a shooting game machine, especially a The infrared type 4 shooting game machine and method can use a number of reference points arranged at irregular intervals to change the difficulty level 5 and the environment of the game according to the measured distance, thereby providing a realistic and interesting game. [Prior Art] The present invention is an improvement of Korean Patent Application No. 10-2002-43913, entitled "Adjustment of Game Difficulty and Situation", proposed on July 25, 2002. The content of this patent application, which is closely related to this case, is incorporated into this case. Referring to the first figure, the figure shows a perspective view of a conventional shooting game machine. The conventional shooting game machine includes a game case 1, a screen la, an image generator 2 provided in the game case 1, and a semi-transparent reflective mirror surface. 3 15 An infrared generating device 4 for displaying an image generated by the image generator 2 on the screen 1a, for generating a reference point 7 as a basis for calculating coordinates, and for controlling a control of the entire shooting game machine Device 5, and a target detector 6 for detecting the coordinates indicated by the player based on the reference point generated by the infrared generating device 4. 20 In addition, the shooting game machine further includes a model gun 10 for aligning a target on the image displayed on the screen la. The model gun 10 includes a gun body 10a, a trigger 11, a shock-proof member 12, such as a rubber, a charge-coupled device (CCD) camera 13, a lens 14, and an infrared filter 15. 3 Continued pages (Please note and use continuation pages if the invention description page is insufficient.)

Description of the invention continued page The image detected by the CCD camera 13 is transmitted to the coordinate detector 6 through a communication line 16 connected to the model I 10. CCD camera 13 2 The shape of the CCD is approximately rectangular, and the C (: D is used for the side with more pixels and parallel to the horizontal direction. 5 It is used to display the game in the shooting game machine with the structure described above. The display of the image includes a screen la, an image generator 2 and a translucent reflective mirror 3. The game image information transmitted from the controller 5, including _standard stem, is first converted by the image generator 2 into a light belonging to the visible range, and then by the The translucent mirror surface 3 reflects and is finally irradiated to the screen la, so it can be viewed by the player. In this case, the light emitted from the infrared generator 4 is reflected by the translucent mirror surface 3, and then shines on the screen la. Therefore, the reference point 7 which can be used as the basis for detecting the coordinates is indicated. Yuan Zhen aimed the labor screen 1 a with the model gun in his hand. In this case, the image displayed on the screen 1 a and the reference point 7 are It reaches the infrared filter. 15 At this time, the light belonging to the visible range cannot pass through the infrared filter and the filter 15, and the reference point 7, that is, the light belonging to the infrared range, passes through the infrared filter 15. The infrared filter The fiducial point 7 of 15 forms an image on the (: :(: 1) camera 13 through the lens 14, and the 20 fiducial point 7 which has formed an image on the CCD camera 13 is converted into an image composed of electrical signals, and the electrical signals are then composed The image is transmitted to the coordinate detector 6. At this time, when the player pulls the trigger 11, the coordinate detector calculates the coordinates of the reference point and obtains the indication coordinates of 8-1222380, that is, according to the coordinates of the reference point, the player The indicated coordinates on the indicated screen la. The indicated coordinates obtained as described above are transmitted to the controller 5, and the controller 5 compares the coordinates at the time when the player pulled the trigger 11 with the indicated coordinates of the indicated 5, according to To determine whether to hit the target. However, due to the reference points generated by the infrared generating device 4, there are always-or two or more are not distributed in the image week garden according to the specified rules, and the player's instruction coordinate system is assumed to be a model gun 1 〇 It is detected under the condition of no rotation, so the conventional shooting game machine has a missing 10 points that cannot calculate the position correctly. That is, as shown in Figure 4a, in the conventional shooting game machine, two reference points {C The coordinates of the reference point on the CD camera 13 are ρm = (ριχ, Piυ), P2 = (P2χ, Pπ) (assuming the origin of the coordinates of the CCD camera is the upper left corner), and the coordinates of the center of the screen la on the screen la is The 15 (xg 'yg)} stored in advance is arranged approximately symmetrically to the center of the screen la, and only when the CCD camera 13 detects all the reference points, the indicator coordinates are detected. The coordinate detector 6 is used to calculate the CCD The coordinates of the reference point on the camera 13 {Pι = (Ριχ, p1Y), ρ2 = (ρ2χ, ρ2γ)} and the way to obtain the center of gravity to calculate the center of the reference point on the CCD camera η (because these reference points are determined by 20 Arranged symmetrically with «la center, so the center of these reference points becomes the seat of ^)" {ρ〇 == (ρ〇χ, ρ〇γ) The distance D is calculated from -9-1222380. _Stomach d = d (P2X -ριχΫ + (p2Y -Ριγ) 2, so the center coordinate of the CCD camera 13 on the CCD camera 13 is C = (CX, CY) When the distance between each reference point on the screen la is L, the indication coordinate is meaning = ^ + ((^-/ 7. /) # a And find. a 5 Therefore, when the player's position is very close to the screen la or away from the screen la (the CCD camera cannot detect all the reference points), the conventional shooting game machine cannot obtain the correct pointing coordinates. In addition, as in the present invention, When the rotation of the model gun 10 is taken into consideration, the conventional shooting game machine cannot obtain the correct indication coordinates, because the method used by the conventional shooting game machine to calculate the coordinates of the instruction 10 does not take into account the rotation of the model gun 10. In addition, since the conventional shooting game machine uses all the displayed reference points to detect the indication coordinates 8 indicated by the player, and uses the aforementioned method to detect, if the infrared generating device 4 partially fails, some of the benchmarks are caused. When the point is not detected, the conventional shooting game machine will have the disadvantage of being unable to detect the coordinates of the indicator 15 of the indicator 8. In addition, because the conventional shooting game machine can only detect the indication coordinates when all the used reference points are detected, the conventional shooting game machine has the disadvantage that the CCD camera of the same size can detect a small range. In addition, in the conventional shooting game machine, the player can only play the game in a manner of passively responding to the game content provided by the controller 5 20. In addition, the conventional shooting game machine cannot reflect the rotation of the model gun 10 and the change in the distance between the remaining model 10 and the screen 1 a, so -10- 1222380 Invention Description S stomach can not provide a realistic Disadvantages of the game. The distance between the model gun 10 and the screen la can be changed depending on the player. Players in good physical condition can reduce the distance and play the game at a position close to the screen la. Since being closer to the screen la improves shooting accuracy, 5 fair games cannot be played. All players want to play the game near the screen la. In addition, since the CCD camera 13 used in the conventional shooting game machine is not fixed and can be freely moved by the player, an image can be detected by the same CCD. The conventional shooting game machine does not detect the indication coordinates according to the aforementioned restricted reference point distribution, so as to make good use of the resolution. The index used by the shooting game machine to detect the image is the resolution, and the CCD resolution of the CCD camera directly affects the resolution of the image detection. Increasing the CCD resolution is the easiest way to increase the resolution of image detection. However, this method will increase the cost of the CCD and increase the number of data to be transmitted and processed. Therefore, high-speed transmission methods and high-performance processing equipment are required. Therefore, there are restrictions on cost and technology. [Summary of the Invention] The present invention is proposed in order to overcome the aforementioned problems occurring in conventional techniques. 20 The purpose of the present invention is to provide a shooting game machine and method that can change the game environment according to the distance between the model gun and the screen, thereby improving the game environment.

When the distance is large, the player is given a discount. Another object of the present invention is to provide a shooting game machine and method, in which a number of reference points are arranged according to a certain rule, so that the reference coordinates can be calculated using some of the reference points, so not only a CCD with the same resolution is used The camera can calculate the indication coordinates in a wide range, and the low-resolution CCD camera can also calculate the indication coordinates in the same range. 0 15 Another object of the present invention is to provide a shooting game machine and method, which can set a model gun The reference distance from the screen, and if the actual distance is smaller than the reference distance, reduce the size of the target, impose penalties, and increase the azimuth of the bullet to increase difficulty; and if the actual distance is greater than the reference distance When it is large, it increases the size of the target, and provides convenience, etc., to benefit the player. In order to achieve the foregoing object, the present invention provides a shooting game machine including a display for displaying various images including a target; Base-12-1222380 Invention Description $ Selling stomach on-point display for displaying a number of irregularities The intervals are arranged in or around the display as the reference point on which the coordinates are detected; the indicator is used to point to a point indicated by the player on the display; the image detector is mounted on the indicator for detection Measure an image in 5 areas of the area indicated by the indicator; a reference point coordinate detector for receiving the detected image and detecting the coordinates of the reference point; an indicator coordinate detector for detecting based on the detected The reference point coordinates to detect the indication coordinates indicated by the indicator; and a controller for adjusting the difficulty level according to the distance between the display and the indicator, receiving the detected indication coordinates and controlling the entire shooting 10 game machine. The irregular intervals between the benchmarks should be determined by various conditions of the shooting game machine, such as the resolution of the display, the resolution of the image detector, the visible range and rotation limit, and the relationship between the display and the indicator. Distance. 15 The datum point coordinate detector should detect the actual information of the detected datum points based on the distance ratio between the detected datum points if the image detector only detects part of the base points. . The indicator coordinate detector should detect the indicator coordinate based on two of the partial reference points detected by the image detector. 20 The shooting game machine should further include a rotation detector for detecting the rotation of the indicator according to the reference points. The controller should control the image displayed on the display according to the change in the indication coordinate detected by the indication coordinate detector or the rotation detected by the rotation detector. The shooting game machine preferably further includes a distance measuring device for detecting the interval between the reference points on the display stored in advance and the interval between the reference points detected by the image detector 5. Measure the distance between the display and the indicator. The controller should control the image displayed on the display according to the change of the indication coordinate detected by the indication coordinate detector, or the distance between the display and the indicator detected by the distance detector. 10 The controller should control the image displayed on the display based on changes in the coordinates detected by the indicator coordinate detector. Preferably, the indicator should include an image generator, a semi-transparent mirror, and a screen for displaying the image reflected by the semi-transparent mirror. The reference point display is located behind a translucent mirror. 15 Preferably, the indicator should be a model of a gun, tennis racket, baseball bat, stick, or sword. In order to achieve the foregoing object, the present invention provides a shooting game method, which includes the following steps: (a) displaying various images including a target on a display, and displaying a plurality of base points which are used as a basis for detecting coordinates; (B) detecting a partial image of an area of a point indicated by a pointer manipulated by the player; (c) receiving the detected image, detecting the coordinates of each of the reference points, and according to each of the Seat of which the reference point has been detected -14-12380 Description of the invention, _ stomach

The distance D between the display and the indicator should be calculated by the following equation D f (L / d), where f refers to the focal length of a lens, and l refers to the coordinates obtained from each of the reference points stored beforehand. The distance between the reference points, and d refers to the interval between the reference points on a CCD camera; wherein the front end of the indicator is equipped with the lens, and the rear end is equipped with the CCD camera. If the distance D is shorter than the reference distance do, the azimuth angle δo of the pointer should be increased. If the distance D is greater than the reference distance Do, the azimuth angle δo of the indicator 15 is decreased.

Otherwise, if the distance D is greater than the reference distance do, the game situation is set to be beneficial to the player. 5 [Embodiment] With reference to the following detailed description in conjunction with the drawings, the foregoing and other objects, features, and other advantages of the present invention can be better understood. The second figure is a perspective view of a shooting game machine constructed in accordance with the present invention. 10 In addition to the model gun, the game case 1 is equipped with various το pieces constituting a game machine. The screen ia is a device that displays a number of reference points, which are used as a basis for detecting content images including a target and an indication coordinate. The image generator 2 is a device that generates various images, including games and target content. Another brown pot or projector is used for image generator 2. The display for indicating the target includes the screen 1a, the image generator 2 and the semi-transparent mirror surface 3 in structure. However, if the image generator 2 is directly installed at the position of the screen u in the second figure, a display excluding the screen 1a and the translucent mirror 3 can be constructed. 20 The infrared generating device 4 is a reference point display device for generating reference points. These reference points are the basis for detecting the coordinates indicated by the player, that is, the indicated coordinates. The generating device is an infrared laser, and is located on the inside, the outer periphery or the back of the screen. The datum points generated by the datum point display are displayed inside or around the curtain 1 a and form the basis for detecting the coordinates. The details will be described later. 5 The reason why the reference point generating device uses the infrared generating device 4 is because the game image displayed on the screen la is composed of electromagnetic waves of invisible rays, so as mentioned above, the reference point cannot be distinguished from the game image. Use infrared rays and pass light through the infrared generating device 4 to display the reference points, so that the reference points are detected correctly and clearly. 10 In addition, since the present invention uses a specific rule to determine the interval as described later, and then uses the reference points arranged at the interval to calculate the coordinates, in addition to the reference points, points that do not need to be detected can be exempted. , So that the coordinates of the indicator are further detected correctly. The infrared generator 4 is located behind the translucent mirror 3, and the reference point 15 should be arranged along the horizontal axis passing through the vertical axis of the screen 1a. The infrared reference point generated by the infrared generating device 4 passes through the translucent reflecting mirror surface 3 and is displayed on the screen ia. If the structure of the display belongs to the position where the image generator 2 is provided on the screen la without using the screen ia and the translucent mirror 3, the infrared generating device 4 may be provided on the periphery of the screen la or near it. The controller 5 is a tool for controlling the entire shooting game. It transmits the image including the target to the image generator 2 so that the player-17- 丄 222380 description of the invention, the game image can be seen on the continuation page. The player moves to change the game content, and determines if the target is hit in order to manage the game. The controller 5 can be implemented by a general microprocessor. The model gun 10 is a pointer that can be pointed on the screen la by the player, and it can be replaced with a tennis racket, a baseball bat, a stick, and a sword. The model gun 10 includes a CCD (charge transfer device) camera 13, a lens 14, an infrared filter 15, an image detector that can detect the image in the area indicated by the pointer, and a player for the player The trigger 11 is fired when 10 is notified. CCD cameras can be replaced with complementary metal-oxide-semiconductor (CMOS) devices. The function of the red light filter 15 is to receive various images of the game, including targets displayed on the screen, eliminate light in the visible range, and allow electromagnetic waves in the infrared region to pass. 15 The reference point composed of various electromagnetic waves in the infrared region is formed on the CCD camera 13 by the lens 14, and then converted into an electric signal, and transmitted to the coordinate detector 6 through the communication line 16. The coordinate detector 6 includes a 20-reference-point coordinate detector that detects a reference point coordinate using a signal detected by the image detector and transmitted via the communication line 16 and a detection method based on the reference-point coordinate. The coordinates of each reference point detected by the tester are used to detect an indication coordinate detector, which is indicated by the player through the pointer. -18- 1222380 Description of the invention Continuation page The coordinate detector 6 includes a converter that can convert these analog signals into digital signals when the signals transmitted by the model gun 10 are analog signals. The coordinate detector 6 can always detect the indicator coordinates, so that the game content can be changed according to the player's actions when playing the game, or the indicator coordinates can be detected at the moment of pulling the trigger 5 to reduce the control. Burden of the scanner 5 or the coordinate detector. The point indicated by the player is transmitted to the controller 5 when the indication coordinate is detected by the indication coordinate detector, and is compared with the target position coordinate at the moment when the player pulls the trigger 11 to determine Whether player 10 hits the target. The arrangement of the reference points constituted according to the present invention will be described later. The conventional shooting game machine uses one or two reference points. For example, when using three or more fiducial points, they are only used when they are arranged near the screen at regular intervals. In contrast, since the present invention uses a reference distance ratio of 15 points, after considering the screen la resolution, the resolution of the CCD camera, the visible range (the screen u range that can be simultaneously detected by the CCD camera), and the rotation limit ( The maximum rotation angle that can be noticed when the player points at the image) 'and the resolution of the gun, that is, after the model gun 10 can detect the range of the screen la, at least three reference points will be arranged at predetermined intervals. 2 In this article, the process of correctly detecting the coordinates of each reference point can be divided into the following steps, that is, to find the actual information of the detected reference points, that is, to determine the detected reference in the order of the reference points. -19-1222380 where the point occupies. 发明 说明 #Selling stomach step, and the step of detecting the indicated coordinate using the detected reference point. In order to determine the position occupied by the reference points in the order of the reference points, the CCD camera 13 must always detect at least two distances, that is, at least three reference points. Because it is not necessary to detect all the reference points, the coordinates can be detected even with a low-resolution CCD ancestor 13. In order to always detect at least three of the several reference points, the interval between the reference points is the resolution of the CCD camera 13 (if the interval between the reference points is large, a high-resolution CCD camera can be used, and vice versa You can use a low-resolution CCD camera), the rotation limit of the CCD camera 13, the resolution of 10 shots, the resolution of the screen 1a, and the player's main position during the game as the determining factors. At the same time, the reference point display must be adjusted. In order to display these reference points at predetermined intervals. For example, 'If the rotation limit of the CCD camera 13 is limited to 30 degrees, then the entire screen 15 la can be detected within a 30-degree rotation range, but if the rotation angle of the CCD camera 13 exceeds 30 degrees, Then at least three reference points at the end of the screen la will not be detected at the same time. In addition, if the standard position is randomly arranged, if the pointer is closer to the standard position, the image analysis capability of the CCD camera 13 becomes higher. However, if the indicator is closer to any limit point, the end position of the screen cannot be measured. 20 Conversely, if the position of the pointer is far from the standard position, the image resolution of the CCD camera 13 becomes low. Since the screen size can be variously changed, and the standard position is -20-1222380 proportional to the screen size, when determining the interval between the reference points, the resolution, visible range and rotation limit of the CCD camera must be used, and The resolution of the gun is used as a basis, and constants that determine the size of the screen la and the standard position are obtained at the determined interval. For example, if 150 cm is the standard position of a screen of 5 73.66 cm (29 inches), then 258 cm is the standard position of a screen of 127 cm (50 inches). With the foregoing method, for screens 1a of various sizes, various reference point configurations can be used to maintain the same effect. In addition, because the gap between the reference points becomes larger, it is easier to distinguish the known base points from other reference points. Although the reference point display is set outside the periphery of the screen la, the aforementioned reference points can be displayed near the periphery of the screen la. However, as shown in the second figure, the reference point display should be provided behind the translucent reflective mirror surface 3. In order to display these several reference points on the screen la. 15 If these reference points are arranged outside the screen la, then the CCD camera 13 installed on the model gun 10 to detect the image of the area indicated by the player, that is, as shown in the third a, must be on the model gun The 1Q is mounted so as to be offset therefrom, so that the design of the model gun 10 is limited. If these reference points are arranged within the screen 1 a, as shown in Figure 3b 20, the CCD camera 13 can be installed on the model gun 10 to align with its axis, so that the design of the model gun 10 is eliminated. limit. The foregoing reference point configuration restrictions can be corrected with the following mathematical equations: 21- Description of the Invention The continuation page does not show (as shown in Figure 4a, it is based on the number of these reference points along the vertical axis through the labor curtain 1 a Example of horizontal axis arrangement). The peripheral critical difference ET with the minimum distance required by a minimum distance of at least three reference points within a certain distance from the periphery of the screen la (or the periphery of the area where the image is detected), and the periphery of the screen la (or detection with a CCD camera) The general critical error GT used to detect the minimum distance required for the minimum distance of at least three reference points can be calculated by the following mathematical methods when the internal area of the screen la is excluded). 10 The horizontal resolution of the model gun is Sw (because the reference point is indicated along the horizontal axis, so it is not used), the vertical resolution of the model gun is SH 'CCD camera's horizontal resolution is cw, and the CCD camera's vertical resolution When the value is CH, the rotation limit angle of the CCD camera is%, and the rotation angle of the CCD camera is Θ (〇d ^ c), if α (θ) and Α (θ) are defined as / ^ (θ): Mody c " C0se 15 Ρ2 (θ) = sin0J ^) + cw c〇s6 2 ~ 2 ~

2tan0 2 ^ Then calculate it with the following equation

The minimum value becomes the value of ET and GT (if two or more conditions to the right of Ετ (θ) are met, the result is calculated). ΕΤ (Θ) is always defined_ 丨 ⑻ 丨 (present) 2+ (chat) 2 of (D2 (〇) < 〇) (| AW | < | AW |) (_ 丨 、 _ 丨) -22 -1222380 GT # 2 Undefined invention description Continued yin) 2+ (Liao 23 to date) 2+ (continued) 2) Otherwise, if θ ((Κθ < θθ (undefined) is not calculated ET (Θ) and GT (e ), ETT (Θ) and GT (e) do not exist.

The reference points are arranged to maximize the interval between these reference points within a range of 5 domains that meet the conditions of ET (Θ) and GT (e). For example, since ET and GT are 58.58 and 142.99 respectively, if the limit angle is 15 degrees, at least three reference points should be set within a distance of 58.58 from the periphery of the screen la, and the three reference points should be 142.99. Set within the distance to maximize the interval between the reference points. 10 Calculate the value mathematically according to the resolution and visible range of the CCD camera 13, the resolution of the model gun, the resolution of the screen la, and the standard position, and then arrange the reference points based on these values to calculate more accurately. Out of coordinates.

The one shown in FIG. 8a is a view of a method 15 using a CCD camera according to conventional techniques, and the one shown in FIG. 8b is a view of a method using a CCD camera according to an embodiment of the present invention. The actual, mass-produced and commonly used CCDs are manufactured in a 4: 3 ratio to match the aspect ratios of commercial TVs and monitors (320x240, 352x288 '400x300, and 640x480). The resolution of the CCD used is 20 (360x240 and 720x480), where the number of pixels on the vertical axis is greater than the horizontal axis. -23- 1222380 Take a CCD with a resolution of 320x240 as an example, as shown in Figure 8a, because the vertical axis with more pixels is set parallel to the horizontal direction, so the model gun 10 used in conventional shooting game machines can detect the most The resolution of the measured image is 320x240 ° 5 However, if the vertical axis with more pixels is as shown in Figure 8b, it depends on

In the embodiment of the present invention, it is set to be parallel to the vertical direction, that is, the CCD is used after being rotated 90 degrees, and then the reference points will be densely arranged along the horizontal direction according to the rule, so that the vertical axis image detection resolution 80 will not cause problems. Therefore, if the 4 · 3 ratio of a normal screen la is used, the resolution of the horizontal axis which is set to 10 parallel to the horizontal direction is 427 (320x4 / 3). As a result, even with the conventional CCD, the resolution can be increased by (427x320) / (320x240) = 136,640 / 76,800 = 178%, so that the image detection resolution can be increased by 178%. Based on the foregoing configuration, the operation of the embodiment of the present invention will be described later.

The sixth figure is a flowchart of the entire system constructed according to the embodiment of the present invention. When the player points the model gun 10 at the target displayed on the screen la in steps S00 and S01, the reference point is detected by the CCD camera 13 mounted on the model gun 10 at step S02. The reference point detected by the CCD camera 13 is transmitted to the coordinate detector 6 via the communication line 16, and the coordinate detector 6 will be eliminated in step S03. -24-1222380 Description of the invention _ stomach

Interference points that can interfere with the reference point. Since the information of the reference point has been stored in the shooting game machine in advance, the detected points are compared with the reference point information to determine whether each detected point is a reference point, and the interference point can be eliminated. / 5 / After removing the interference points, determine whether the number of remaining points is three or more in step s04. The reason for this is that if the number of detected reference points is three or more, the coordinates of the present invention can be detected. If the remaining points are more than three, then use the seat that will be explained later in step s05; the algorithm calculates the indication coordinates, and calculates the distance between the labor curtain 10 la and the player, and the rotation of the model gun 10 angle. If there are less than three points remaining, return to the initial step. The indication coordinates, the distance between the screen la and the player, and the rotation angle of the model gun 10 are transmitted to the controller 5 and reflected in the game content including various images and target sizes. After 15 h, determine whether the player has pulled the trigger at step SG6. If the player does not pull the trigger, it returns to the initial step. If it has been pulled, then in step S07, compare the current indicated coordinate with the target coordinate to determine whether the target has been hit. Finally, it is determined at the step whether the game has ended '. If the end signal is not quietly detected, it returns to the initial step. 20 What is not shown in FIG. 7 is a flowchart of coordinate calculation algorithm according to an embodiment of the present invention. Take the following as an example. The screen la has a resolution that can be plotted in the range of 0 to 400 -25-1222380 in the horizontal direction. The CCD camera 13 has a resolution of 320x240. Use the side with a high resolution parallel to the vertical direction (the center coordinate of the CCD camera is (120, 160)), and the reference point is arranged at (19, 43, 58, 14 and 175, 200, 5 225 , 259, 342, 357, 381).

The position of the reference point is stored in the shooting game machine in advance, and the interval between adjacent reference points is (24, 15, 83, 34, 25, 25, 34, 83, 15, 24), and the interval ratio of adjacent reference points is (0.625000, 5.533333, 0.409638, 0.735294, 1.000000, 1.36000, 10 2.441176, 0.180722, 1.60000) 〇 At step S001, when the player points the model gun 10 to the screen la or rotates the model gun 10, if it is the reference input via the CCD camera 13 When the number of points exceeds three, the process of sensing the movement and detecting the coordinates is started. If the number of previously entered reference points is more than three, the interval between the reference points is calculated in step S002.

When the distance between the adjacent reference points is calculated, the ratio of the intervals between the adjacent reference points is sequentially calculated in step S003. After calculating the interval ratio between adjacent reference points in step S003, if the number of input reference points is three, then in step S015, the reference point with the most appropriate interval ratio and the specified interval ratio of 20 is found. In the previous example, if three reference points are input and the interval ratio is 0.42, then 0.409638 is the closest value, and the detected reference points are regarded as the third, fourth, and -26-1222380.发明 说明 # Stomach five benchmark. In step S003, in step S025, if the number of input reference points is four or to find the reference point of the position interval with the smallest error of the specified interval ratio. In this example, if five reference points are entered, and the ratio is in order of magnitude: 4.07, M3, and 2.42 Risi, then when the continuous reference points are estimated from the interval ratio and compared with each other, the minimum errors are 0.735294, L360000 and 2.441176, so the detected reference points are the fourth, fifth, sixth and seventh reference points.

10 ^ In this case, if the seventh reference point cannot be detected due to the failure of the reference point display, the fourth, fifth, and sixth reference points are detected, so that the coordinates can be calculated. The coordinates of the reference point are detected by the reference point coordinate detector based on the previously detected reference points. In step S006, the coordinates of the point indicated by the playbook can be obtained in the following manner.

The number of reference points used to calculate the coordinates is two. When detecting three reference points, the two reference points on the left are used to calculate the coordinates. When detecting four or more reference points, two reference points should be used, including the reference point closest to the center of the CCD camera and the reference point next to the closest reference point to calculate the indication coordinates. If the coordinates of the two reference points on the CCD camera 13 (assuming the upper left corner is the origin) are A 仏) and P2 = (/ v ~), the center coordinates of the CCD camera 13 are C = (c; 〇cv ), According to the size order and reference point -27-1222380 Invention description The predetermined values corresponding to the continuation page are II and 込, and e and d are defined as e =-/ ^, / ^ 一 ~) and ^ = V ( P2X ~ P \ x) 2 + ^ Ρ2Υ ^ Ρ \ γ) 2 'are used to calculate the X and Y coordinates respectively. In this case, assuming that a lamp is located at the center of the monitor, 5 is the calculation equation for the X and Y coordinates. If the lamp is not in the center, the calculation equation is different.

If it is assumed that the origin of the coordinates on the screen la is the intersection between the extension line of the screen la reference point and the left, then the previously defined values ^ and 12 should be the coordinates of the horizontal axis of the screen la. For example, when the third and tenth reference points are used to calculate the indication coordinates, the values of I and I2 are 58 and 121, respectively.

After calculating the indication coordinates indicated by the player, it is convenient for step S07 to calculate the inclination of the indicator based on the coordinates of the known reference point and the coordinates of the previously entered reference point, and then to obtain the rotation angle of the indicator. The equation for the 15 rotation angle is cos- ^ Pu-PM / V ^) (radians). If the sign of (Pu--Ar) is positive, the positive sign indicates that the indicator has rotated to the right. If the sign is negative, the negative sign indicates that the indicator has been rotated to the left. After calculating the rotation angle of the pointer, the distance between the reference point on the ccd20 camera 13 and the reference point on the screen la obtained by previously inputting the reference point coordinates is measured at step s08. Actual distance. The distance between the screen u and the indicator and the CCD camera 13 have been checked -28-12222380 Invention description, the distance between the reference points on page M is D and d, and the focal length of the lens 14 and the coordinates of the reference point according to the previous input When the distances between the obtained reference points are f and L, respectively, the distance 0 between the screen la and the pointer is obtained as 0 and f (L / d). 5 The figure 10 shows the process of changing the difficulty and situation of the game according to the distance d between the screen la and the pointer. Referring to the tenth figure, the player aims the target on the screen 1a with the model gun 10 at step S101, and then shoots with the model gun 10. At this time, when the position of the model gun 10 is changed in step S102 ', that is, the distance D between the model gun 10 and the screen la is measured in the shooting game machine without interruption. In step S103, the shooting game machine determines whether the measured distance is properly maintained. That is, as shown in the ninth figure, the distance between the screen 1 & and the pointer changes depending on the player's motion. The appropriate distance is now defined as the reference distance D0. At this time, if the reference distance% is not a point, but 15 is a distance having a certain change range, the change range is set to DGa ~ DGb. In step S104, if the distance D is measured and the measured distance D is within the variation range, the normal state is maintained in step 104 and a normal game is provided. If the measured distance 0 does not match the change range, that is, the measured distance D is a shorter distance Di or a larger distance 20 DG, then the difficulty or situation of the game is changed in step S105. That is to say, a difficult-to-condition game environment is provided according to the distance from the model gun 10, thereby arousing player's interest in the game. -29- 1222380 5 10 15 Description of the Invention _ Stomach 10th-_10th-e is a specific example of changing the difficulty of the game and the situation of the game. The eleventh a $ 丨 丨 丄 a to eleven e are flowcharts of various examples for changing the difficulty and the situation of the game. Referring to the eleventh figure a, after the distance D and the change range D0a ~ D0b have been evaluated in step SU0, if the distance D is less than the change range, that is, the position of the model record 10 is close to the screen. Distance Di), when the player pulls the trigger 11 in step S111, 'the bullet fired will deviate from the position ^ That is, the bullet misses the player's alignment mark' but instead hits the target in a direction Skewed coordinates. This will reduce the possibility of hitting the target when the player shoots with the model gun 10. Therefore, it may be that something other than the target was hit. The equation of the specific example at this point is as follows. Figures twelve a and twelve b are views of this view. The twelfth figure (a) shows only the bullet traces when the pure angle error center inherent to the model gun 10 itself is stored. The one shown in Figure 12b is not only a pure error angle Ss, but also an error angle of 5s when the shooting game machine will cause the bullet to deviate. This equation is for illustration only and can be modified freely. δ〇 == lSs ^ Um- (kx \ ds-d \) (d < ds) V Other aspects

Ss ·· the inherent error angle ds of the model gun ·· the critical distance between the model gun and the screen k: a constant determined according to the model gun -30-1222380 Description of the Continuation of the Invention Conversely, if the distance D is greater than any After a distance, an action is taken to increase the shooting accuracy at step S112. In other words, even if a bullet deviates from the target, it can be regarded as a bullet that has hit the target. 5 Referring to the eleventh figure b, after the distance D and the change range D0a ~ D0b have been evaluated in step S120, if the distance D is less than any distance in the change range, it is reduced when the player pulls the trigger n in step S121. Target size. That is, the target size is adjusted according to the distance from the model gun 10, so that the same or difficult 10 conditions are provided regardless of the position of the model gun 10, thereby reducing the possibility of hitting the target. The following is an example of an equation on this point. (Lx ^ \ ds-d \ (d < ds) VL other reduced length ds: critical distance between the model gun and the screen k: a constant set according to the target 15 Conversely, if the distance D is greater than any of the change range The distance is to increase the size of the standard trunk at step S122. Referring to the eleventh figure, after evaluating the distance D and the change range DorDob at step S13, if the distance D is less than any distance in the change range, then the step S131 imposes a 20 penalty on the player when the player pulls the trigger u. The penalty imposed can be various, for example, during a period of -31-1222380, the player's movement rate in the game environment is greatly reduced. This prevents the player from cooperating with the game environment. When the player jumps in the game environment, the player can limit the jumping height or increase the shooting interval to make continuous shooting difficult, or increase the speed of the target so that the player cannot easily follow the target. Conversely, if 5 The distance D is greater than any distance in the variation range, that is, in step § 13 2 to provide the player with the normal game as usual, or to give the player a reward. See FIG. 11d, which was evaluated in step S140. After the distance d and the change range D0a ~ D0b, if the distance D is less than any distance in the change range, the size of the screen displayed on the screen is reduced in step S141. This 10 moves are to reduce the target sight size, Therefore, the size of the target is reduced. On the contrary, if the distance D is greater than any distance in the variation range, the size of the target is increased in step S142. That is, as the distance increases, the target size also increases with the distance. It is proportionally increased so as to maintain the player's ability. Figures 13a and 13b are examples of the foregoing process. Figures 15a and 13a are shown when the model gun 10 is away from the screen u, The size of the picture displayed on the screen la. The one shown in Figure 13b is the size of the picture displayed on the screen 1 & when the position of the model gun 10 is close to the screen 1 & Changes D〇a ~ D〇b are evaluated at step 20 s 150. If the distance D is less than any distance between changes D〇a ~ D〇b ', then the game is changed when the player pulls the trigger 11 at step S151. A game situation means that the game has an indirect effect Set or back-32-1222380 scene. Conversely, if the distance D is greater than any distance in the change, that is, while maintaining the same scene and background in step S152, make the standard rounds clear, so that It is easy for the player to aim at the target. As mentioned earlier, when the player holds the indicator, that is, the model gun 5 10, the point at which the player is aligned on the screen 1a is correctly calculated. Taking the rotation into consideration, the pointing position can also be calculated correctly. In addition, even when a part of the reference point is detected by the CCD camera 13, this pointing coordinate detection method can also calculate the pointing position. Therefore, as shown in Fig. 4b, even if a CCD camera 13 having the same CCD resolution is used, those indicating coordinates can be detected in a wide range. With a low-resolution CCD camera, the index coordinates can be calculated in the same range. In addition, as shown in Figure 5a, if some of the reference point displays fail, and thus some of the reference points cannot be displayed, the conventional shooting game 15 can calculate its tf coordinate. In the present invention, as shown in FIG. 5b, although some of the infrared generating devices 4 fail, and thus some of the reference points are not shown, the point indicated by the player can still be calculated. The distance between the pointers increases the useful life of the shooting game machine. 20 Furthermore, the present invention can calculate the rotation of the pointer and the distance between the screen 1 & and the pointer, and the controller 5 can adjust the difficulty of the game and automatically change the image of the game based on the calculated rotation and distance. . -33- 1222380 发明 说明 # Selling page In other words, if the player approaches the screen la, he can easily hit the target, so that the controller 5 can increase the moving speed of the target or reduce the size of the target to increase difficulty. Conversely, if the player is away from the screen la, the controller can reduce the target's moving speed or increase the size of the target to reduce the difficulty.

In addition, the conventional shooting game machine does not care about the player's actions when processing the game, but the controller 5 of the present invention changes the image of the game in response to the rotation or movement of the pointer or the distance from the pointer. Therefore, since the player can change the difficulty and progress of the game as the player responds to the action 10, the player can play a more realistic shooting game. The above embodiments are only used to illustrate the present invention, and are not intended to limit the scope of the present invention. Various modifications or changes that do not meet the spirit of the present invention are within the scope of the present invention.

15 As mentioned above, the present invention can change the game environment according to the distance between the model gun and the screen, so that the player is very interested in the game. The present invention is to increase the interest in the game by changing the game video or providing different levels of difficulty, based on which the progress of the game is changed. In addition, according to the present invention, if the actual distance is shorter than the reference distance set between the model gun and the screen, it will make the game more difficult, and if the actual distance is shorter than the reference distance, the player will be given a discount, so Provides effects that allow fair handling of the game. For example, if the actual distance is -34- 1222380

Description of the Invention When the stomach reference distance is short, the target size is reduced, penalties are imposed, and the 10,000-degree angle of the bullet is increased to increase difficulty. If the actual distance is greater than the reference distance, the size of the target is increased, and convenience is provided to benefit the player. 5 Therefore, as players play this game,

In response to changes in the rotation or distance of the type gun, the difficulty and progress of the game are changed, so the present invention has the effect of providing a shooting game that is consistent with reality. In addition, there are several reference points arranged in accordance with a specific rule, so that only a part of the reference points can be used to calculate the indication coordinates, so not only can a CCD camera with the same resolution be used to calculate the indication coordinates in a wide range, but also A low-resolution CCD camera can also calculate the index coordinates in the same range. -35- Continued description of the invention [Simplified description of the drawings] f A picture is a perspective view of a conventional shooting game machine; 々 The second picture is a perspective view of a county-level machine constituted by the present invention; A schematic diagram of a conventional model gun material screen, and the one shown in FIG. 3b is a schematic diagram of a model gun aimed at the screen according to an embodiment of the present invention;
