In this paper consideration is given to the application of the measurement reduction method to the problem of introducing graphical information into a computer with a digitizer. An algorithm is described, which takes into account the errors arising in the graph pickup and the position of the graph on the digitizer plotting board. The algorithm makes it possible to obtain the most precise values of the coordinates of the graph points. Estimates for the concomitant error are presented.
