7.3.4 Bead Tool

The Bead tool is used to inspect parts on which an application of adhesives or sealant material has been
placed. In an industrial setting, this "bead" of material is commonly applied in a strip on a known path. The
Bead tool can look at this pre-defined path and verify whether the adhesive or sealant has been correctly
applied.

For the purposes of this tool, a bead is any long, narrow strip of approximate consistent width and approximately
consistent color. The bead must have sufficient contrast with its background so that a simple grayscale
thresholding scheme, like that used in the Blob Tool, can separate the two. Background clutter and optical
noise (i.e. shiny spots, holes in the bead) are permitted, but their presence may degrade the robustness of a
bead inspection.

The Bead Tool also assumes that the bead material has been applied by a mechanized system and thus is
quite consistent in location and direction. The tool does not attempt to detect, follow, or account for variations
in bead location.

Usage

• Check for uniformity of a bead of adhesive.
• Check for the uniformity of a gap.
