● Improve the accuracy of 3D scanner

   The automatic calibration method greatly increases the calibration accuracy of the

   three-dimensional scanner and ensures the calibration accuracy of the 

   three-dimensional scanner. The positioning accuracy is as high as 0.001mm.

 ● Improve recognition rate

    The photolithography process is adopted to ensure that the pattern boundary is clear,

   complete, sharp and good recognition.

 ●Automatic corner detection function

   There is no need for complex point and corner process, with obvious black-and-white

   contrast of pattern quality, special instrument, target cell grid by grid calibration, and 

   overlay corner grid by grid calibration technology.
