New description: [New technical field] This creation is about a cursor control method and a briefing system using the cursor control method, aiming to provide a briefing system for an external cursor and an internal cursor. [Prior Art] In the conference report, it is often necessary to convert the ideas and information that the reporter wants to transmit into text, charts and patterns onto the screen or wall by the projector. Liquid crystal projectors (Liguid Crystal Display) and DLP (Digital Light Processing) projection devices are often used as image projection sources, and these images are the charts, texts, and patterns that users want to express. These images are made by personal computers (PCs). Or a notebook computer (notebook); the computer generates a projection software, such as microsoft PowerPoint, to generate the projection image that needs to be generated when the presentation is made; and the computer output image format has a standard VGA format, super VGA or XGA format. The way LCD is equipped with _ PC for presentation work has gradually replaced the traditional transparent slides and has gradually become another new trend. Usually, the optical indicator is used to indicate the projected image, so that the viewer can immediately know the part that the presenter wants to explain, and the external cursor formed by the optical indicator and the internal cursor of the computer often make the audience Confusion, there is a briefing system on the market that can move the external cursor and the internal cursor synchronously. As shown in the first figure, the computer 10 is connected to a projector (llor) and a camera 12 respectively. The projector 11 projects the image 13 output from the brain 3 to the projection plane 14, such as a screen. An optical pointer 15 projects the outer cursor 16 onto the projection plane 14. The camera 12 captures the image 13 on the projection plane 14 and the external cursor 16. Thereafter, the captured image 13 and the external cursor 16 are processed via the computer 1 and an appropriate control command is generated to move the internal cursor 17 to a position near the outer cursor 16. However, when the camera 12 is not on the projection optical axis of the projector u, when the projector 11, the projection plane 14 or the camera 12 is moved, the relative positional change between them will cause the size of the image of the captured image to change and the cursor position There is an error, so it needs to be recalibrated before the internal cursor 17 is used. Li [New content] There is a clock here. The main purpose of this creation is to provide a briefing system for the mutual alignment of the cursor and the internal cursor. In order to achieve the goal, the cursor of the creation (4) method group external cursor and the internal cursor are aligned with each other on the --surface, the n-method ❹ 部 游 cursor Leilian #, # inside. The 卩/軚 軚 is generated by a computer, and the electric film is projected onto the developing device through the projection device and can simultaneously capture images and materials on the imaging plane; 2 filtering the light to reflect the external cursor to the image sense The detector is detected by the ^ 测 料 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ It is not necessary to recalibrate the coordinate change each time it is not triggered due to the cast. [...] The relative position of the image plane is changed. [Embodiment] In order to make the 遂 遂; ^ I „ and the implementation method: ～ 委 清楚 clearly understand the main technical content of this creation, the paper with the diagram is as follows: There are: In the fourth picture, the presentation system 2 of this creation includes at least one computer 21; - projection slaughter " storage 1 and projection light machine (Fig. 2, 'the projection device 22 is provided with a lens 221 The projection device 22 is connected to the computer 21 by the projection device 22, and the image is outputted with a lens 221' to receive the computer 21, and the projector can be recorded to project the image onto the development plane 23 Wherein, the image 31 and the external cursor 42 on the projection hi 3, the image projection of the optical machine via ά f § 1 > and the captured image are located on the optical axis of the projection light machine = plane of the lens image; the imaging plane 23 For displaying the image, the image has an internal cursor 24 generated by the computer 21; at least one optical indicator 41 for projecting an external cursor 42 on the imaging plane 23; In the present embodiment, the optical component is mainly composed of a filter 25, The image 31 projected by the projection device 22 and the external cursor 42 are received, and the external cursor 42 is reflected or refracted to the image sensor 26; an image sensor 26, the image sensor 26 can be complementary a composite metal-oxide semiconductor (CMOS) or a charge coupled device (CCD), the image sensor 26 is connected to the computer 21, in the embodiment shown in the figure, the image The M374605 sensor 26 and/or the filter 25 can be disposed in the projection device 22 and measure the external cursor 42 at the first position A1 of the image 31. In actual use, the computer 21 transmits the signal to the projection. The device 22 outputs an image 31, which is outputted to the development plane 23 via the lens 221 and projects the external cursor 42 onto the development plane 23, and simultaneously captures the image on the development plane 23. And the external cursor 42 captures the image through the lens 221 and receives the light to the filter 25. The light of the external filter 42 can be reflected or refracted to the image sensor 26 by the filtering action of the filter 25. Again, the newsletter system is the first In the second use, the image 31 on the imaging plane may be first aligned with the four points (P1^P2, P3, P4) of the sensing pixel array 261 in the optical sensor as shown in the fourth figure, so that The sensing pixel array 261 of the optical sensor can correspond to the image 31 of the imaging plane. The library closes the Hr domain 42 and the (4) cursor 24 to correct and obtain mutual gold: the image sensor 26 has an imaging plane The 23 phase heart, the dan, for example, corresponds to the outer cursor 42 in the image "raw == y. ,), and the external cursor 41 moves to: and the computer 21 can also obtain the internal swim 2) and = the cursor 24 moves to the second position 2 with its "X2"; the internal cursor 24 can be based on the above-mentioned outer cursor position difference The amount of compensation value is set, and the correction step is close to the first position. The external cursor 42 moves and the younger one is used. The same internal cursor 24 is moved to move the M374605 value, so that the external cursor 42 can be internalized. The cursor 24 moves synchronously. It is worth mentioning that this creation has the following advantages compared to Xiyou: 1. This creation does not require additional use of the camera, and the cost is lower. 2. Capture or project images directly through the projection lens. 3. In the briefing system, the camera is not on the projector's projection light. As shown in Figure 5 (A), the projector is at position A, and camera J is at position B, and when the projector is projected. When the plane or camera is moved, • The relative position change between them will cause the picture size of the captured image to become φ 4匕. As shown in the fifth figure (B), the original image is C1-C4, and the relative position is changed. The image is Cl'-C4'; in this creation, the image projection and the captured image of the projection device are all located on the same optical axis, as shown in the sixth figure (A), the image projection A of the projection device and the capture The image B is located at the position C (C=A=B), so when the relative position of the projection device and the developing plane is changed, as shown in the sixth figure (B), the captured images are not moved to the original position and the projection is not made. The image on the imaging plane is skewed. 4. At least one set of external cursors can be used and can be tracked accordingly. As mentioned above, this creation provides a better and feasible briefing system, and the application for a new type of patent is submitted in accordance with the law; however, the above description and drawings show that the preferred embodiment of the present invention is not limited thereto. This creation is based on the fact that the structure, installation, characteristics, etc. of the creation are similar, and the same should be the creation purpose of the creation and the scope of patent application. w/4605 [Simple description of the diagram] The first picture is the perspective view of the structure of the first type A/r-F1 injury.
