The authors have developed a device consisting of a system of perception of images of printed characters and a personal computer (PC), which determines the types of characters. According to the program developed by the authors, the PC contours the image of the printed symbol in a rectangular matrix consisting of the cells of the PC's storage device. As a result of the edging of the shape of the printed symbol, essential and necessary signs were determined - the directions of the elements of the shape of the symbol, according to which, using the developed algorithm, the PC determined the type of this symbol relative to others. The perception system includes a small-sized television tube - a vidicon with a generator of sweeps of a vidicon beam on its screen vertically and horizontally, two channels and a coincidence circuit. The developed system of perception is distinguished by: simplicity of design, compactness, efficiency.
