A machine vision process and apparatus for reading a plurality of separated figures, such as the hole-position diagram of a printed-circuit board; the apparatus comprises an X-Y table to be moved on a plane and to be positioned at a given position, two photographing devies such as camaras being mounted over the X-Y table, and an image processing unit. The X-Y table is used for placing a diagram or the like so as to facilitate a first camera to photograph a large area and to facilitate a second camera to photograph a small and detailed separated figure. The image signal obtained will be transmitted to the image processing unit to find out the center coordinates of every separated figure, and the size and shape of every separated figure classified so as to find out the control data of size, position and the moving path in the real production process.
