The cursor emitter 50 can switch between external cursors that project multiple colors. In the present embodiment, the cursor emitter 50 is provided with a first button, a first button and a second button, and the cursor emitter 5 发出 can respectively emit external cursors of three colors of green, red and blue. The image capturing module 1 includes a finder frame 101, a photographic camera 102' range finder 103, an image processing unit 104, and a coordinate compiling unit 105. The finder frame 1 用于 1 is used for locating the camera 6 201039229 angle of the photographic camera 1 〇 2 so that the photographic camera 102 can be respectively aligned with the display screen of the computer 20 and the projection screen 40 . The photosensitive camera 102 is configured to capture a display screen of the computer 20, the projection screen 40 and the external cursor. The range finder 103 emits infrared illuminating light for sensing the distance between the display screen of the computer 20 and the image capturing module 100 and sensing the projection screen 40 and the image 撷Take the distance between the modules 100. The image processing unit 104 is connected to the photosensitive camera 102 and the range finder 103, and calculates the display screen size of the computer 20 and the projection of the projection screen 40 according to the input data of the photosensitive camera 102 and the range finder 103. The size of the area, as well as the color of the external cursor. The coordinate encoding unit 105 receives the image signal transmitted by the photosensitive camera 102, converts the image signal of the projection screen 40 into a first coordinate with the center point as a coordinate origin, and displays the image signal of the screen of the computer 20 as J^ The heart point is converted into a second coordinate from the coordinate origin, and the position coordinates of the external cursor in the first coordinate are acquired according to the external cursor captured by the photosensitive camera 102. When the image capturing module 100 is in an initial state, the finder frame 101 is located on the display screen of the computer 20, the photographic camera 102 captures the display screen of the computer 20, and the finder 103 measures the location The distance between the display screen of the computer 20 and the image capturing module 100 is calculated. The image processing unit 104 calculates the size of the screen lighting area of the computer 20, and the coordinate compiling unit 105 displays the image of the screen of the computer 20. The signal is converted to the second coordinate with its center point 7 201039229 coordinate origin. The finder frame 101 is positioned on the projection screen 40, the photographic camera 102 captures the projection screen 40, and the finder 103 measures the relationship between the projection screen 40 and the image capturing module 100. The image processing unit 104 calculates the projection area size of the projection screen 40, and the coordinate compiling unit 105 converts the image signal of the projection screen 40 into a first coordinate with the center point as a coordinate origin. When entering the normal use state, the photosensitive camera 102 captures the projection screen 40 and the external cursor, the image processing unit 104 acquires the color of the external cursor, and the coordinate compiling unit 105 acquires the external The coordinate position of the cursor. The cursor signal processing module 200 is connected to the image capturing module 100, and includes a digital signal processing unit 201, a cursor movement processing unit 202, and a cursor click processing unit 203. The digital signal processing unit 201 is connected to the image processing unit 104 and the coordinate compiling unit 105, and the input signal of the image processing unit 104 is used to calculate the projection area size of the projection screen 40 and the electric brain. 20: displaying a ratio between screen sizes, and calculating a coordinate position of the internal cursor of the computer 20 in the second coordinate according to the scale in combination with the coordinate position of the external cursor in the first coordinate. For example, when the ratio between the projection area size of the projection screen 40 and the display screen size of the computer 20 is A, the coordinate position of the external cursor is (ζ, Ό, then the internal cursor is in the second The position coordinate in the coordinate is x'=4ax 5 y'=4ay. The digital signal processing unit 201 transmits the coordinates of the internal cursor at the position of the second seat 8 201039229 to the cursor movement *% of the digital signal The processing unit 201 knees only & 202 t, the same data _ in the filament (four) processing unit plus the cedar cursor color "== rational unit 2 ° 2 generated by the internal cursor in the position coordinates of the second seat The internal cursor moves the signal. The light of the factory is clicked on the processing unit 2〇3 by the external light: click the signal. In the present embodiment, when the acquisition is replaced by the color of the A, the no-click is issued. When it is blue k, the right click signal is issued. The cursor driving module drives the internal cursor to move to the corresponding position according to the coordinates of the internal cursor at the position of the second coordinate, and performs corresponding click operation according to the internal cursor color. The cursor driving module is connected to the cursor signal processing module 2 and the computer 2, and the signal output by the cursor movement processing unit 202 moves the internal cursor to the corresponding position, and is clicked by the cursor. The signal output by the processing unit 2〇3 drives the internal cursor to perform a corresponding click operation. In the embodiment, the cursor driving module 300 is connected to the computer 2 by a USB interface. The image capture module 1 captures the size of the projection area of the display screen of the computer 20 and the projection screen 40. The cursor signal processing module 300 calculates the display screen and the projection screen 30 of the computer 20. The ratio between the size of the light-emitting area, the coordinate compiling unit 1〇5 converts the image signal of the projection screen 40 to the first coordinate with the center point as the coordinate origin, and displays the image signal of the computer 20 as the center point. The coordinates origin is converted to the second coordinate. When entering the working state, the user uses the cursor 9 201039229 transmitter 50 to emit an external cursor to the projection screen 4〇, the image 撷-module 100: Acquiring the color of the external cursor, the coordinate compiling unit • still obtaining the position coordinates of the external cursor at the first coordinate command, the cursor signal processing module 300 is displayed by the computer 2 and the projection screen% of the light emitting area The size ratio is combined with the position coordinates of the external cursor in the first coordinate to calculate the coordinate position of the internal cursor in the second coordinate. The cursor signal processing module 3 (9) generates an internal cursor driving signal by the internal cursor in the second coordinate position coordinate, externally The cursor color generates a cursor click signal, and the cursor driving module 300 generates an internal cursor by the cursor signal processing module 3 signal and drives the internal cursor to perform corresponding operations. Referring to FIG. 4, it is a computer control method flow. The computer control system includes a computer and a projector. The data in the computer is projected by a projector onto a projection screen. The projection screen is projected by an cursor to project an external cursor. The computer control method includes The following steps: S101 'Using a camera unit to capture the computer display screen, projection screen and The external cursor 'measures the distance between the computer display screen and the projection screen and the camera unit' to calculate the size of the computer display screen and the projection screen projection area; S102, converts the projection screen image signal to the first coordinate with the center point as the coordinate origin.
