Abstract
This thesis shows how you can use two simple webcam, to create smart
board. To do this, we have a simple whiteboard and two cameras. You
can track the writings on the board with the camera images taken
from board. The cameras features is almost same. The first camera in
the top right corner of the board and the second camera in the bottom
left corner will be installed. Both cameras are set up in ways that
provide a complete picture of the entire board. The cameras are
connected to a laptop or computer and Received images from them be
processed online. Processing video from cameras is performed with a
program written in C ++ and using OpenCV library. The program, read
each video frame by frame. Also, a single image from the board and
from the angle of the face is taken. In the first stage with image of the
face, each frame of the right camera is transformed by turning
perspective. Next, the frame of the left camera is also transformed
using perspective transform. The images obtained from the two
previous stage, are calibrated to each other with the help of the two
corresponding point. In the next step we have two images to become
an image that contains two images information, using bit operations.
Finally, the image of One Step Before will be processed, using the bit
operations based on watershed transform, and additional objects, such
as a writer on-board will be deleted and only the text remains on the
board. In this way, the output will be a video that works to track and
display writhing on the board.
