A machine vision detection method and system for bevel gear wear |
| abstract |
The invention relates to a machine vision detection method and system for bevel gear wear. The method includes: scanning the bevel gear to be inspected with a photographic measuring device to determine a three-dimensional point cloud model of the bevel gear; preprocessing the point cloud data of the wear defect of the bevel gear in the three-dimensional point cloud model of the bevel gear, and determining the preprocessed bevel gear Gear wear defect point cloud; establish a standard coordinate system according to the three-dimensional point cloud model of the bevel gear; extract the contour information of the bevel gear based on the standard coordinate system; according to the bevel gear wear defect point cloud, the bevel gear outer contour The fitted conical profile shape and the fitted conical profile shape of the inner profile of the bevel gear determine bevel gear wear parameters. The invention can improve the work efficiency of the bevel gear wear evaluation, and at the same time ensure the universality of the measurement suitable for different types of bevel gears. |
