Abstract: In order to measure a distance with high accuracy, a corresponding pixel extraction section reads a projection transformation matrix from a storage section, determines a reference pixel corresponding to a standard pixel, and outputs the pixel value thereof to a correlation value computation section.

A distance computation section extracts the point of the smallest value of an addition value input from the correlation value computation section and the points before and after it, creates a second-order curve passing through the three points, and outputs a distance corresponding to the smallest value of the second-order curve, as the distance of the standard pixel, to a distance image memory.

Abstract: In a protective coating formulation requiring the use of polyamine molecules, oleic acid is used as a very effective additive to remove any excess polyamines. The carboxyl groups of the oleic acid molecules react with the amine groups of the polyamines to form a harmless amide molecule. The oleic acid thus removes excess pollutants from the final coating. In addition, the oleic acid reduces the viscosity of the coating before curing, making it easier to apply to surfaces, and decreases the curing time necessary. However, the addition of oleic acid does not affect the beneficial characteristics of the coating in any way.
