AI Technical Summary
Existing technologies have low efficiency in detecting counterboring parameters, making it difficult to achieve comprehensive quantitative analysis. Traditional gauge measurement and coordinate measuring machine (CMM) measurement are inefficient and can damage the counterbored workpiece.
A combination of line laser measuring instrument and zoom microscopy was used to acquire three-dimensional point cloud data of the countersunk hole. The geometric morphology of the countersunk hole was fitted by the RANSAC algorithm, and the countersunk hole parameters were calculated.
It enables efficient and accurate detection of countersunk hole parameters, avoids damage to countersunk workpieces, improves detection accuracy and efficiency, and can fully inspect the inner and outer diameters, axial deviation angle, cone angle and recess depth of countersunk holes.
