Abstract
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.
Claims20
A method comprising:
- computing first dimensions of an item based on a first image of the item comprising a view of at least two or more surfaces of the item;
- comparing one or more surface features of the item in a second image with one or more surface features of the item in the first image;
- validating an identity of the item based on the comparison between the one or more surface features in the first image and the one or more surface features in the second image wherein the one or more surface features comprise at least one of a corresponding color characteristic and a corresponding chromatic characteristic of a respective surface;
- in response to successfully validating the identity of the item in the first image and the second image, computing second dimensions of the item based on the second image of the item comprising a view of a single surface of the item;
- comparing the second dimensions of the item based on the second image with the first dimensions of the item based on the first image;
- and
- in response to determining that the second dimensions are not within a predefined threshold of the first dimensions of the item, rejecting the second dimensions based on the second image.

A dimensioning device, comprising:
- a camera configured to capture images of an item;
- a processor configured to:
- compute first dimensions of the item based on a first image of the item comprising a view of at least two or more surfaces of the item;
- compare one or more surface features of the item in a second image with one or more surface features of the item in the first image;
- validate an identity of the item based on the comparison between the one or more surface features in the first image and the one or more surface features in the second image, wherein the one or more surface features comprise at least one of a corresponding color characteristic and a corresponding chromatic characteristic of a respective surface;
- in response to successful validation of the identity of the item in the first image and the second image, compute second dimensions of the item based on the second image of the item comprising a view of a single surface of the item;
- compare one or more surface features of the item in the second image with one or more surface features of the item in the first image;
- and
- in response to determining that the second dimensions are not within a predefined threshold of the first dimensions of the item, reject the second dimensions based on the second image;
- and
- a graphical user interface (GUI) configured to:
- render second dimensions and the second image on a display with a sign that indicates that the second dimensions of the item are inaccurate.

A non-transitory computer readable storage medium comprising instructions, which when read and executed by a computer processor are operable for performing, controlling or causing a process, the process comprising:
- computing first dimensions of the item based on a first image of the item comprising a view of at least two or more surfaces of the item;
- comparing one or more surface features of the item in a second image with one or more surface features of the item in the first image;
- validating an identity of the item based on the comparison between the one or more surface features in the first image and the one or more surface features in the second image wherein the one or more surface features comprise at least one of a corresponding color characteristic and a corresponding chromatic characteristic of a respective surface;
- in response to successfully validating the identity of the item in the first image and the second image, computing second dimensions of the item based on the second image of the item comprising a view of a single surface of the item;
- comparing the second dimensions of the item based on the second image with the first dimensions of the item based on the first image;
- and
- in response to determining that the second dimensions are not within a predefined threshold of the first dimensions of the item, rejecting the second dimensions based on the second image.
