查询词典 displacement

The apparatus regards the laser beam, emanating from the laser device, which can emit the perpendicular laser to the earth, as the measuring norm. The facula on the autodyne, which clings to the guide way during the measuring, is sampled to computer with a CCD camera and an image acquisition card. By computer image proce~sing, the measuring apparatus can identify the displacement of the facula center .By this way it determines the verticality error of the guide way at the measuring position, which can be recorded automatically at the same time.
