Embodiment
[0030] Use the method of the present invention to measure such as figure 1 The measured slewing body shown needs to measure the axial size of each abrupt cross-section. The steps are as follows:
[0031] 1. The high-precision linear array CCD sensor and the parallel light emitter are located on the symmetrical sides of the rotating body, the contour of the rotating body is imaged on the CCD, and the optical image processing technology is used to output two measured values in the radial direction of the rotating body at this point When the CCD sensor moves along the axial position in sequence, two contours of the revolving body are obtained, which constitute a longitudinal section of the revolving body. Due to the installation error of the revolving body, the shape of the revolving body obtained by the measurement has a certain tilt, such as figure 2 Shown.
[0032] 2. According to the measured longitudinal section profile data, find the symmetry axis of the two busbars, such a...
