The present invention relates to an electronic teaching desk system using image processing based on binocular vision. The electronic teaching desk system comprises a teaching desk, a transparent board, left and right cameras, a system control unit and an image output device. The transparent board is arranged on the teaching desk, and enables writing on a blackboard. The left and right cameras are arranged on the rear left and right of the transparent board and respectively obtain left and right images including writing information written on the transparent board. The system control unit receives the left and right images respectively obtained from the left and right cameras and extracts a writing image by removing a background image and reversing the left and right. The image output device receives the writing image extracted from the system control unit and outputs the same on a screen. 본 발명은 쌍안시 영상처리를 이용한 전자 교탁 시스템에 관한 것으로, 교탁과, 투명보드와, 좌,우측 카메라와, 시스템 제어부, 및 영상출력장치를 포함한다. 투명보드는 교탁에 배치되며, 판서가 가능하게 형성된다. 좌,우측 카메라는 투명보드의 후방 좌,우측에 배치되며, 투명보드에 판서된 판서 정보를 포함한 좌,우측 영상을 각각 획득한다. 시스템 제어부는 좌,우측 카메라로부터 각각 획득된 좌,우측 영상을 제공받아 배경영상 제거 및 좌우 반전시켜 판서 영상을 추출한다. 영상출력장치는 시스템 제어부로부터 추출된 판서 영상을 제공받아 화면에 출력한다.
