Digital Image Processing Applied in Wheel Hub PCD Measurement

Abstract:

The wheel hub PCD (Pitch Circle Diameter) is the diameter of the circle whose circumference connects the centers of all bolt holes in the hub. Common bolt patterns are four, five and six-hole patterns, etc, and the product of the number of holes and PCD is an important parameter of wheel hubs. This article discusses the digital-image-processing-aided precise measurement of geometric data of hole-distributions, such as bolt-hole-center coordinates x0 and y0, pitch circle diameter PCD, angle between adjacent bolt holes θ, axle-hole-center coordinates and the radius from each bolt hole to the center of the axle hole, etc.
