Abstract:
1. A method for automating the measurement of straightness of linear stock material, comprising: determining an end centroid for a perpendicular cross-section of the linear stock material at each end of a segment of the linear stock material; determining at least one intermediate centroid for a perpendicular cross-section of the linear stock material disposed within said segment; establishing a virtual longitudinal axis of the linear stock material between each of said determined end centroids; for each intermediate centroid, determining a measure of displacement from said virtual longitudinal axis; for each intermediate centroid, determining a measure of angular orientation about said virtual longitudinal axis; utilizing each said determined measure of displacement and each said determined measure of angular orientation to identify a direction and magnitude of concavity in the linear stock material; and storing a representation of said identified direction and magnitude of concavity for said segment of linear stock material.
