The error analysis of the on-line measurement system used in the processing parts of numerically-controlled machine is investigated, and the image processing technilogy is analyzed through the investigations on error source, error analysis and geometrical error analysis, in which, much consideraton is paid to the image treatment and the object margin extracting process conducted to the images segmented and disposed in terms of image preprocessing and segmentation. Therefore, such an investigation is of great importance to enhance the machining precision of parts.
