The distance in pixel between the crosshair and its image returned from the plane mirror is calculated to achieve angular metrology on the basis of software algorithm. Compared with the conventional autocollimation, the angular measuring method may avoid artificial error and enhance measuring efficiency enormously, accordingly make the course more quickly and handily, and be available to the automatic detection of CNC positioning accuracy.
