Electronic whiteboard capable of simultaneous writing and projection storage

An electronic whiteboard capable of simultaneous writing and projection storage, comprising an electronic whiteboard body, an optical reflection bar (2) being disposed on an inner side of a frame (1) of the electronic whiteboard body, wherein two groups of infrared camera modules are disposed in the middle of the frame (1), the two groups of the infrared camera modules are mirror-symmetrical on the left and right and separate the electronic whiteboard body into a left-region electronic whiteboard (4) and a right-region electronic whiteboard (5);

• each group of the infrared camera module comprises infrared cameras (3) disposed on upper and lower ends of the inner side of the frame (1), the two infrared cameras (3) on the left face leftwards, and the two infrared cameras (3) on the right face rightwards;
• touch mainboards (14) of the left-region electronic whiteboard (4) and the right-region electronic whiteboard (5) are each connected to the two infrared cameras (3) of the electronic whiteboard in the corresponding region;
• a first projector (6) connected to the left-region electronic whiteboard (4)/right-region electronic whiteboard (5) is disposed at the top of the left-region electronic whiteboard (4)/right-region electronic whiteboard (5);
• the left-region electronic whiteboard (4) and the right-region electronic whiteboard (5) are each provided with a built-in touch mainboard (14);
• the touch mainboard (14) of the left-region electronic whiteboard (4)/right-region electronic whiteboard (5) without the first projector (6) is connected to an input end of a computer host of an electronic whiteboard computer (13);
• and an output end of the computer host is connected, through the first projector (6), to the touch mainboard (14) of the left-region electronic whiteboard (4)/right-region electronic whiteboard (5) that is provided with the first projector (6).
