The starting point of the drawing corresponds to the X of the X-axis and the Y-axis coordinates 値x2 and y2 at time t2, and the end point of the drawing is determined. In the present invention, the three-dimensional coordinate 指示 of the pointer is calculated with one fixed point as a reference point. Further, the drawing image generated by the drawing means determines the image type corresponding to the position of the Z-axis coordinate 値zl at the time t1, that is, the position in the depth 〇 direction of the pointer. In a preferred embodiment of the present invention, the drawing image in the presentation system may be a line 'in the case where the z1 is relatively close to the display surface, and the image correction is performed on the relatively thick line, and in the zl In the case where the 値 is relatively far from the display surface, the image correction for making a relatively thin line is performed. According to the preferred embodiment of the present invention, when the pointer approaches the display surface, the relatively thick line is drawn to mean that the line is drawn away from the display surface. In general, the publisher has the habit of bringing the pointer closer to the display surface in the case where the portion to be emphasized is indicated. Therefore, in the part that you want to emphasize, draw a thick bottom line or a thick mark. Thus, the preferred embodiment of the present invention is a presentation system that more closely matches the preferences of the publisher. However, in the present invention, the image correction is not limited to the preferred embodiment, and may be corrected to a relatively thin line, for example, when the pointer approaches the display surface. In another embodiment of the present invention, the presentation system may further have a depth, a memory, and a depth determination means for memorizing the predetermined depth ;; the depth determination means compares the z and the depth 该 of the z1, in the zl When the depth 满足 is satisfied, the drawing means generates the drawing image. According to the preferred embodiment, the drawing is performed when the pointer is at a depth of a fixed range. For example, when the presenter moves closer to the display surface and moves the pointer, the drawing is performed. The operation of the pointer near the podium is defined as an operation for inputting a command, and the presentation system can also be constructed as such. In general, the presenter has a habit of moving toward the fixed depth direction on the display surface or the like in the display surface when the image is created such as a slide. Therefore, the preferred embodiment is a presentation system that more closely matches the publisher's habits. In another embodiment of the present invention, the presentation system may further have a moving distance 値 memory unit and a first operation determining means for storing the predetermined moving distance ;; the first operation determining means may calculate the time at the time ti The distance between the position of the pointer and the position of the pointer at time t2 is compared with the moving distance ,, and when the calculated distance satisfies the moving distance ,, the first predetermined operation is performed. According to the preferred embodiment of the present invention, when the pointer moves at a specific speed, 200947261, it is determined that a predetermined operation (e.g., an input command) is input, and a predetermined operation such as changing the display image can be performed. In general, the "publisher has the habit of quickly moving the pointer when asked to feed a slide or the like" and slowly moving the pointer when explaining the slide. Thus, in the preferred embodiment, by adding an input of a predetermined operation by changing the moving speed of the pointer, it becomes a presentation system more in line with the taste of the publisher. A predetermined operation is exemplified, which is a page inversion of a created image, a stop of a so-called animation in which a change in image is displayed, a stop of sound generation, and the like. The invention described above, the preferred embodiments of the invention, and the constituent elements contained therein may be combined and implemented as much as possible. [Effect of the Invention] According to the present invention, the three-dimensional coordinate 指示 of the pointer is calculated with one fixed point as a reference point. This fixed point is fixed between the continuous stabilization function of this presentation system. Therefore, only the three-dimensional coordinate 値 calculation processing is performed on the pointer. Therefore, the calculation efficiency is improved. Further, it is a briefing system that increases the processing speed, prevents malfunctions, and the like.

[Embodiment] Hereinafter, a briefing system 1 according to an embodiment of the present invention will be further described with reference to the drawings. The dimensions, materials, shapes, relative positions, and the like of the members or portions described in the embodiments of the present invention are intended to be illustrative only and not intended to limit the scope of the present invention. 200947261 Fig. 1 is a block diagram of the briefing system 1. The presentation system 1 is composed of a display surface 2 belonging to a screen, a pointer 3, a first camera 4, a second camera 5, and a system controller 8. The image display of this embodiment is performed using the projector 6 and the screen. However, in the present invention, the display surface 2 is not limited to a screen, and may be, for example, a display surface of a liquid crystal display or the like. The display surface 2 is a plane that expands in the X-axis direction and the γ-axis direction. In the present invention, the plane includes a geometrically defined plane and a curved surface that is adapted to the characteristics of the projection machine or display. Further, in the present invention, the X-axis and the Y-axis are the relative relationship between the Z-axis indicating and expressing the distance from the display surface. The first camera 4 and the second camera 5 are cameras for capturing a three-dimensional space including the display surface 2, and may be a motion picture camera or a still image camera. However, in order to perform a smooth drawing or the like, since the image is preferably obtained at a speed of, for example, about 60 frames per second or more, the first camera 4 and the second camera 5 are preferably moving image cameras. For example, a CCD camera can be used for the first camera 4 and the second camera 5. Θ The first camera 4 and the second camera 5 preferably have the entire surface of the display surface 2 as a field of view. As shown by the field of view 7 in Fig. 1, the field of view including the contour area of the display surface 2 is preferable. The camera included in the single presentation system is not limited to two, and may be three or more. The indicator 3 is, for example, a red or green object. The shape of the object is, for example, a sphere or a cube. In order to facilitate the operation of the presentation system 1 by the movement of the pointer 3, it is preferable to attach the indicator 3 to the front end of the stick. Further, the presenter may wear a glove such as red or green in one hand, and the -10-200947261 glove as the indicator 3. The indicator 3 is a means of operating the presentation system 1. The pointer 3 moves or stops in the field of view of the first camera 4 and the second camera 5. Also, move to or stop beyond the field of view. The indicator in the field of view is detected and the presentation system 1 is operated. The system controller 8 is, for example, a computer. The system controller 8 includes a created image recording unit 11, a target color LUT12 belonging to the target color lookup table, a three-dimensional coordinate storage unit 13, a lens correction coefficient storage unit 14, an image-space conversion coefficient storage unit 15, and a moving distance 値 memory. The unit 16 , the drawing image type storage unit 17 , the drawing correction storage unit 18 , the depth 値 memory unit 19 , the photographic image storage unit 31 , the lens corrected image storage unit 32 , and the memory unit of the indicator suffix memory unit 33 The means for creating the image selecting means 21, the display control means 22, the coordinate calculating means 23, the drawing means 24, the first operation determining means 25, the command control means 26, the target color determining means 27, the depth determining means 30, and the main control The unit 28 and the peripheral device control unit 29. The above means can be obtained by a program loaded by a computer, a CPU, a RAM, a ROM, and the like. Each of the above-described memory sections can be obtained, for example, by assigning a fixed portion of the hard memory of the computer. Further, the created image selecting means 21 can use, for example, a program for a briefing system on the market. The main control unit 28 performs overall operation control of the system controller 8, and the like. The peripheral device control unit 29 performs operations of the first camera 4, the second camera 5, image processing, and control of the projector 6. Further, the system controller 8 has a system display device 41 and an input device 42. The system display device 41 is a liquid crystal display attached to a computer, and the input device 42 is a keyboard and an indicator such as a mouse. (Start setting) -11 - .200947261 Describes the operation of the initial setting of the presentation system 1, and so on. The created image displayed on the display surface 2 is created and stored in the created image memory unit 11. The created images are text, graphics, photos, illustrations, motion pictures, and mixtures of these. Also, the created image may be an image of white paper. A specific example of the created image is a slide original for presentation. The type of the drawing image is memorized in the drawing image type storage unit 17. The types of drawing images are, for example, solid lines, broken lines, a little chain line, a circular mark, a triangular mark, a quadrangular mark, an arrow, and the like. The type of graphic image that is memorized is also —. The correction of the drawing image is memorized in the drawing correction storage unit 18. The correction items are, for example, the thickness of the line, the shade of the color, the hue, and the like. Moreover, the relationship between zj値 and zl値 is described. For example, the thickness of the correction line is described as the thickness of the line 100 pixels in the case of 0Szl < 50, the thickness of the line 70 pixels in the case of 50Szl < 100, and the thickness of the line in the case of 100Szl < 150. Pixel. Further, for example, if the color tone is corrected, it is described as red in the case of 〇 $ zl < 100, orange in the case of 1 〇〇 $ Zl < 200, and yellow in the case of O 2 00 Szl < 300. (Environment setting) Next, set the environment. The environment setting is to set the presentation system 1 to the actual use place, and to input the desired data to the presentation system 1 in accordance with the illumination state, the range of the pointer movement, and the like. The presentation system 1 is set in the presentation place, and the display surface 2 and the projector 6 are arranged. The first camera 4 and the second camera 5 are arranged, and the camera field of view 7 is adjusted. The camera field of view is fixed during steady operation in the subsequent environment settings. Next, the presentation system 1 is taught to recognize the object color. Fig. 3 is a diagram -12- 200947261 A flowchart of the color teaching process of the object, and Fig. 2 is a description of the content of the object color LUTl 2. The pointer 3 is positioned in the camera field of view 7 at S11', and the image including the indicator 3 is captured by the first camera 4 and the second camera 5. In si2, the captured image of the first camera 4 and the captured image of the second camera 5 are stored in the captured image storage unit 31. The captured image of the first camera 4 is called from the photographic image storage unit 31 at S13' and displayed on the system display device 41. At S14, the pointer 3 area on the system display device is designated by the input device 42 φ. The first recognition target color C1 is taught by this operation. At S15, the first recognition target color C1 is stored in the target color LUT12. The non-indicator area is designated in the same image displayed on the system display device 41 at S16'. The first non-identification target color NC1 -1 is taught by this operation. The first non-recognition target color N C 1 - 1 is stored in the object color LUT 12 at S 1 7 '. S16 and S17 are repeated to teach other non-identifying object colors. Ο Here, in S16, when the same image displayed on the system display device 41 has no non-recognition target color to be taught, it is repeated from the following photographing operation. That is, the image including the specific non-identification target color is displayed on the display surface 2, or the object of the specific non-identification target color is positioned in the camera field of view 7, and is captured by the first camera, and then S12 and S13 are performed. , S16 and S17. As described above, the first recognition target color C1' and the first non-recognition target colors NCI_1, NC1 - 2.....NC1 -η' are taught to the first camera image and stored in the target color LUT12. -13- 200947261 Next, the process proceeds to S19, and the operations of S13 to S18 are repeated for the second camera image. The second recognition target color C2 designated in S14 is substantially the same as the first recognition target color C1 described above, but each is a color material reflecting the color characteristics of the second camera and the first camera. When the teaching of the above-mentioned recognition target color is completed, as shown in FIG. 2, in the target color LUT 1 2, the first camera photographic image memory recognition target color C1 and the non-identification target color NCl-1, NC1-2... ..NCI - η > and recognize the object color C2 and the non-identifying object ❹ color NC2 - 1, NC2-2.....NC2 - η for the second camera photographic image memory. In a briefing system including three or more cameras, a third camera photography image or the like is taught to recognize the target color and the non-identifying target color. Next, referring to Fig. 4, an environmental setting relating to image-to-space conversion will be described. At S21, the image of the reference point for correction has been displayed on the display surface 2. Instead of displaying the image, the same printed matter can be attached to the display surface. The image of the reference point for correction is drawn, for example, a square image or a checkered image. 〇 Then, the display is captured by the first camera 4 and the second camera 5. At S22, the captured image of the first camera 4 and the captured image of the second camera 5 are stored in the captured image storage unit 31. At S23, the captured image of the first camera 4 is called from the photographic image memory unit 31 and displayed on the system display device 41. The image coordinates of the correction reference point on the display image are detected. At S24, the correction reference point for the three-dimensional coordinates (cosm coordinates) is associated with the image coordinates detected at S23. At S25', the three-dimensional coordinates and image coordinates are recorded in the temporary memory. For the other correction reference points, the operations of S 23 to S 25 are repeated. , 14 - 200947261 In S26, the three-dimensional coordinate group and the one-to-one corresponding image coordinate group are called from the temporary memory, and the lens correction coefficient of the first camera image and the first camera image are calculated from the two groups. Image-space conversion factor. The lens correction factor is the coefficient 値, and the image-to-space conversion coefficient is the matrix 値. At S27, the lens correction coefficient of the first camera image is stored in the lens correction coefficient storage unit 14. At S28, the image-space conversion coefficient of the first camera image is stored in the image-space conversion coefficient storage unit ❹15. At S29, the second camera photographic image is operated in the same manner as S23 to S28. By this operation, the lens correction coefficient of the second camera image is stored in the lens correction coefficient storage unit 14, and the image-space conversion coefficient of the second camera image is memorized in the image-space conversion coefficient memory unit. Operation 1) Next, the steady operation processing will be described with reference to the flowchart of the steady operation shown in FIG. 5 and the flowchart of the three-dimensional coordinate determination processing of the pointer 3 shown in FIG. At S40, stable operation is started. In steady operation, the indicator 3 moves or stops according to the operation of the presenter. At S41, the created image selecting means 21 selects one image from the created image memory unit 11. At S42, display control means 22 displays the image on display surface 2. In S430, the first camera 4 and the second camera 5 simultaneously capture the respective fields of view, and the three-dimensional coordinates of the pointer 3 are calculated from the position of the pointer 3 in the captured image. The detailed processing of S430 will be additionally described below. -15-.200947261 By this calculation, the three-dimensional coordinates 値x1, yl, zl of the pointer 3 at time t1 and the coordinates 値x2, y2, z2 at time t2 are memorized in the indicator coordinate memory unit 33. In S51, the drawing means 24 selects one type of drawing image from the drawing image type storage unit 17. For example, in a stable operation, the type of the drawing image may be edited in advance to always select the same drawing image type, or the program may be edited to select the drawing image type corresponding to x1, yl, and zl. At S52, the drawing means 24 refers to the indicator body coordinate storage unit 33, and corrects the drawing image corresponding to 値 of z1. In the case where the drawing image is a line, for example, when the 値 of z 1 is relatively close to the display surface, image correction for making a relatively thick line is performed, and in the case where 値 of z1 is relatively far from the display surface, Perform image correction for relatively thin lines. At S53, the drawing means 24 determines the start point of the drawing image by referring to the x of x1 and yl of the body coordinate storage unit 33. At S54, the drawing means 24 refers to the x of x2, y2 indicating the body coordinate storage unit 33, and determines the end point of the drawing image. © In S55, the drawing means calls the created image which is selected from the created image memory unit 11 and which is selected in S41 and is now displayed on the display surface 2. The process of superimposing the corrected drawing image on S51 to S54 and the created image is performed. The drawing process may also display the drawing image at the forefront, and may not see the form of the superimposed image, for example, it may be a graphic drawing of 50% over-extraction. Then, the image is transmitted to the display control means 22. At S56, the display control means 22 displays the superimposed image on the display surface, if S56 ends, and defines the -16-2° 200947261 data of x2, y2, and z2 in the coordinate unit memory unit 32 as the new xl, yl, zl. . (Stable Operation - 2, Three-Dimensional Coordinate Determination Processing) The three-dimensional coordinate determination processing at S430-3 will be described with reference to Figs. 6 and 7. At S61, the first camera 4 and the second camera 5 simultaneously capture the image at S62, and the captured image of the first camera 4 and the second camera 5 are recorded in the captured image storage unit 31. At S63, the first camera 4 ❹ image is called from the photographic image recording unit 31. At S64, the first camera photographic image is corrected using the lens correction coefficient of the photographic image stored in the lens correction coefficient storage unit. At S65, the image recorder 32 corrects the image storage unit 32 with the lens corrected by the first camera. At S66, the second camera photographic image is subjected to S61 to S65. The lens correction coefficient used in this processing is the second camera photographic lens correction coefficient. Therefore, the second camera has the lens correction image and the lens correction image storage unit 32. 〇 At S67, the first point between the three-dimensional memories memorized by the three-dimensional coordinate storage unit 13 is extracted. The coordinates of the points extracted are referred to as "extracting three 値". The three-dimensional coordinate space is the space that contains the display surface 2 (in the X-axis and Y-expansion) and extends from the display to the front (the direction in which the presenter, the listener is located, and the rear). At the same time, the three-dimensional coordinate space is the space captured by the camera. In the three-dimensional coordinate memory unit 13, the memory divides the three-dimensional space into a small cube or a small rectangular parallelepiped space. Although the Z-axis positive and negative of the three-dimensional coordinate 定义 is defined by the right-handed coordinate system, the Z-axis positive and negative can be corrected as needed. The image is invisible. The image I 1 phase is memorized in the image of the image, and the memory is in the coordinate direction of the coordinate axis (Ζ axis). The field of view 7 coordinates the empty punctuation. However, only -17-200947261 at S68, the coordinate calculation means 23 converts the extracted three-dimensional coordinates into the first camera photography using the image-space conversion coefficient of the first camera photographic image stored in the video-space conversion coefficient storage unit 15. The image coordinates of the image. The converted image coordinates are referred to as "extracted image coordinates". In S69, the target color determination means calls the first camera lens correction image, and refers to the recognition target color C1 for the first camera image in the target color LUT 12, and the non-identification target colors NC1-1, NC1 - 2. ...NCl-n, it is determined whether the pixel of the image coordinates is extracted to match the color of the recognition object. In the case where the color of the recognition target is met, the process moves to S70. When the color of the recognition target is not satisfied, the process returns to S67, and the second point of the three-dimensional coordinate space memorized by the three-dimensional coordinate storage unit 13 is extracted, and the processing of S68 and S69 is performed. At S70, the lens-corrected image of the second camera is processed in the same manner as S68 and S69. At this time, the image_space conversion coefficient used for the conversion of the extracted image coordinates is the image-space conversion coefficient of the second camera image. Further, the color 〇 data in the target color LUT 12 referred to by the target color determination means is the recognition target color C2 for the second camera photographic image, the non-identification target color NC2-1, NC2 - 2.....NC2-n . In S71, the target color determining means 27 determines whether or not the recognition target P color is detected in the first camera captured image and the second camera captured image. In other words, when the pixel of the extracted image coordinate point of the second camera image is determined as the color of the recognition target, the three-dimensional coordinate is extracted as the detection coordinate point of the pointer 3, and is used as the detection target coordinate point. The three-dimensional coordinates are extracted and stored in the indicator coordinate memory unit 33. When the color of the recognition target is not detected in the second camera image, the process returns to S67, and the second point of the three-dimensional coordinate space memorized by the memory unit 13 is extracted, and then the same as S68 and S69. deal with. At S72, the processing of S67-S71 is repeated, and the recognition target color detection processing is performed at all points of the three-dimensional coordinate space. In S73, if the color of the recognition target is detected in the above processing, the process proceeds to S74. If the color of the recognition target is not detected in the above processing, the process moves to S76. At S74, the detection target body coordinate group stored in the indicator body 値 memory unit 0 33 is determined as a point by the coordinate 値 calculation means. Regarding the determination of the point, for example, the center of gravity of the target group of the indicator can be obtained, and the coordinates of the point closest to the display surface can be selected in the group of the indicator body. At S75, the determined detection target body coordinate point is stored as xl and y1'zlo at time t1 in S76, and the process returns to S61, and the target image is detected on the photographic image in the next frame (time t2). Therefore, the coordinates Q points x2, y2, and z2 of the pointer at time t2 are stored in the indicator coordinate memory unit 33. Further, in the case where the camera is three or more presentation systems, then the processing of the lens correction image S 6 8 and S 6 9 of the second camera pair S 70 is performed, and the sum of the lens corrected images of the third camera is performed. , S69 - like processing. In the presentation system using the huge display surface 2, the above-mentioned operation is performed with the environment setting related to the image-space conversion, and the three-dimensional coordinate of the indicator is calculated in the stable operation as long as the range of the extracted three-dimensional coordinate 値 is limited to the indication. The range of body movement can be. In this way, the effect of improving the calculation speed and the like can be obtained. -19-200947261 (Second Embodiment) A briefing system ι (second embodiment) for determining the depth position of the additional indicator of the preferred embodiment will be described. The added depth position determination is a process of determining whether or not to perform a drawing process based on the depth position of the pointer in the three-dimensional space. Figure 8 is a flow chart showing the second embodiment. In the second embodiment, in the stable operation described above, the processing of S81 to S84 is inserted between S430 (determining the three-dimensional coordinates of the pointer) and S51 (starting the drawing). 0 The threshold of the Z axis of the indicator is stored in advance in the depth memory unit 19. Or, the two ends of the Z axis are memorized in advance. In the case of the threshold, it is described that when z 1 is larger than the threshold (or small), the purpose of the drawing process is moved. In the case of both ends, the description goes to the drawing process when zl is located between the two ends (or when it is over). The above-mentioned depths are recorded in the memory and conditions of the 1 million memories. After the detection of the body coordinates in accordance with S430, the depth determination means 30 compares the 记忆 stored in the depth 値 memory unit 19 with the z of the pointer coordinate © 値 memorized by the memory unit 3 3 at S81. In S82, if zl satisfies the threshold condition, the process moves to S83. Further, if zl値 does not satisfy the threshold condition, the process moves to S84. At S83, the process moves to S51 to perform drawing processing. At S84, for example, the command recognition process is started. In the case where command recognition is not performed, return to S5 1 » Command recognition is based on the indication coordinates (xl, yl, zl) (x2, y2, z2) at a plurality of times t1, t2, ..., tn... The combination of xn, yn, zn) is recognized as the processing of a particular command. Entering the command recognition process, if the command is not recognized, return to -20- 200947261 S430 ° The above command processing is an example of the predetermined processing. In the case where the condition of the threshold is not satisfied, the predetermined processing may not be performed, but only the return to S430 » (Third embodiment) The briefing system 1 for explaining the moving speed judgment of the additional indicator belonging to the other preferred embodiment (Third embodiment). The added movement speed judgment is based on the movement speed of the pointer in the three-dimensional space, and it is judged whether the drawing 0 processing or the predetermined operation is performed. Figure 9 is a flow chart showing the third embodiment. In the third embodiment, in the stable operation described above, the processing of S91 to S96 is inserted between S430 (determining the three-dimensional coordinates of the pointer) and S51 (starting the drawing). The moving distance of the pointer is stored in advance in the moving distance 値 memory unit 16. In the present embodiment, the moving distance 値 is a single 临 (premium 値). After the detection of the body coordinates in accordance with the detection of S4 30, the first operation determining means 25 calculates the position of the pointer indicating the time stamp t1 stored in the body coordinate storage unit 33 and the pointer at the time t2 in S91. The distance of the position (calculate the moving distance). In S92, the first operation determining means 25 compares the moving distance 记忆 between the moving distance 値 memory unit 16 and the calculated calculated moving distance. When it is calculated that the moving distance is larger than the moving distance 临 (premise 値), the process proceeds to S93. When it is calculated that the moving distance is smaller than the moving distance 临 (premise 値), the process proceeds to S96. At S93, the first operation determining means transmits a command signal to the command control means 26. At S94, the command control means 26, which has received the command signal, performs the predetermined processing on the created image or the created image selection means in the -21 - 200947261 display. At S95, the display control means 22 displays the image which has been created by the display processing on the display surface 2. At S96, the process proceeds to S51, where the drawing process is performed. The movement distance 値 the memory of the memory unit 16 and the determination by the first operation determination means 25 can be, for example, as follows. (1) Memorize a single threshold, and determine and calculate the magnitude of the moving distance. (2) The two ends of the single range are memorized, and a comparison judgment is made to calculate whether the moving distance is within or out of range. (3) The two ends of the 2 range are memorized, and a comparison judgment is made to calculate the moving distance in any one of the ranges. The command control means 26 that receives the command signal can also perform page inversion for the created image, start and stop the animation, and can also stop the generation of the sound β ® [Simple description of the drawing] Fig. 1 is a briefing system 1 The composition of the figure.
