A vision measuring system includes a vision measuring apparatus. The apparatus includes a first body mechanism, a carrying stage movably mounted in the first mechanism for supporting an article thereon, a second body mechanism spanning the first mechanism, a third body mechanism movably mounted on the second mechanism, and an imaging device movably mounted to the third mechanism for picking up images of the article. Adjusting structures are installed on the apparatus for ensuring the device to be movable relative to the article in three directions perpendicular to one another. The system further includes a motion controller for controlling movements of the stage, the third mechanism, and the device, an input unit, a computer system for converting operating orders from the input unit into electronic signals and sending the electronic signals to the controller, and analyzing image data from the device, and an output unit for displaying analyzing results.
