Visual image technology has been widely used in the defects detecting, classification, automatic recognition and
measuring of industry production. However, it is hard to enhance the resolution and precision of image measurement.
The imaging quality depends on the quality of the device, such as image sensor, image acquisition card and so on.
Without increasing the device quality, a new method is presented to solve the above problems. The directional
measurement technology of high-reflective metallic surface is studied through different measurement angles. With the
multi-angle measurement results, the realization possibility will be analyzed. On this basis, we will find the method of
measuring image information by multi-angles and the proper image processing technology. It is demonstrated by
extensive experiments, compared with the single image of product, that the multiple images could be processed more
flexibly and more effectively. Therefore, the system of image vision can acquire the different level of contrast, and thus,
to much extent, higher level of resolution of image can easily be obtained. This method improves the performance of
system in robustness and accuracy.
