Profiler Meter detection method: This method involves using standard cylinders and standard rollers to position through mobile fixtures, and then moving the probe on the spherical base surface of the roller to be measured to obtain the original contour of the entire spherical base surface. The radius of curvature of the spherical base surface is calculated and analyzed by the instrument program to obtain the detection result.
Image processing method: This method includes steps such as grayscale enhancement, threshold segmentation, and circular radial search. These steps can improve the contrast between the target and the background, better segment the foreground, and realize the contour key point capture through circular radial search, and then fit the center and radius of the circle to improve the fitting accuracy.
Comprehensive precision detection method: For rolling linear guide pairs, the accuracy requirements are very high, including the parallelism of the slider along the guide rail, height deviation, and variation. By using a detector, the measurement results can be accurately displayed, and the accuracy data can be obtained without complex calculations.
