Embodiment 1
[0064] Such as figure 1 As shown, by measuring the basic parameters a' and φ of the projected ellipse, the major axis a of the real ellipse can be expressed by using mathematical functions; as Figure 8 As shown, the oblique section of the cylindrical element is projected through the projection module (CCD camera); and the oblique section projection profile of the cylindrical element is received and displayed through the receiving module. Such as Figure 4 As shown, the wedge angle plane is in the shape of an ellipse, and then the minor axis of the ellipse is marked as a by the minor axis marking module and the major axis marking module is marked as b. Place the measured element horizontally along the axis, and place the projection module (CCD camera) vertically in the direction of the axis of the ellipse to collect the ellipse contour projection. Such as Figure 5 shown. We observe that the minor axis of the ellipse is a, and the projections of the major axis b on the mi...
