Methodology evaluation of computer vision small dimension hole localization

The collection consists of 5 series of scans of MDF samples with holes of different diameters made in different positions (see Samples.tif).

The samples were made on a self-made milling machine and scanned with a flatbed scanner (Canon CanoScan LiDE 200, CIS technology, 4800 dpi).

Samples with the MVC prefix have the selected holes offset by 0.005 inches. The numerical designation after the prefix indicates the diameter of the drill used to make the holes: 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mm.

The samples with the prefixes M0, M1, M2, M5 have all test holes (half of the number of the holes) shifted by, in order: 0, 0.001, 0.002, 0.005 inches. Drills with a diameter of 1.0 mm are used.

The last letter of sample name is used to distinguish repetitions of a sample with the same layout

Samples were used to develop and test the computer vision methodology of small dimension holes displacement.
