Evaluating image values

Evaluating image values

Images of items are evaluated. A first image of the item, having a view of two or more of its surfaces, is captured at a first time. A measurement of at least one dimension of one or more of the surfaces is computed and stored. A second image of the item, having a view of at least one of the two or...

Zusammenfassung:Images of items are evaluated. A first image of the item, having a view of two or more of its surfaces, is captured at a first time. A measurement of at least one dimension of one or more of the surfaces is computed and stored. A second image of the item, having a view of at least one of the two or more surfaces, is captured at a second time, subsequent to the first time. A measurement of the dimension is then computed and compared to the stored first measurement. The computed measurement is evaluated based on the comparison.
