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:
- capturing, by a camera, a first image of an item at a first time from a first perspective associated with a first position of the item, the first image comprising a view of at least two or more surfaces of the item;
- computing first dimensions of the item based on the first image;
- capturing, by the camera, a second image of the item at a second time from a second perspective associated with a second position of the item, wherein the first perspective and second perspective are different, and the second image comprises a view of at least one of the two or more surfaces of the item;
- computing second dimensions of the item based on the second image;
- comparing the second dimensions of the item computed based on the second image with the first dimensions of the item computed based on the first image;
- in response to determining that the second dimensions are within a predefined threshold of the first dimensions of the item based on the first image, determining that the second dimensions are acceptable for computing dimensions of the item;
- and
- in response to determining that the second dimensions are not within a predefined threshold of the first dimensions of the item based on the first captured image, displaying the second dimensions and the second image with a sign that indicates the second dimensions of the item are inaccurate.

A dimensioning device, comprising:
- a camera configured to capture images of an item;
- a processor configured to:
- capture, with the camera, a first image of the item at a first time from a first perspective associated with a first position of the item, the first image comprising a view of two or more surfaces of the item;
- compute first dimensions of the item based on the first image;
- capture, with the camera, a second image of the item at a second time which is subsequent to the first time, from a second perspective associated with a second position of item, wherein the first perspective and the second perspective are different, the second image comprises a view of at least one of the two or more surfaces;
- compute second dimensions of the item based on the second image;
- compare the second dimensions of the item computed based on the second image with the first dimensions of the item computed based on the first image;
- and
- in response to determining that the second dimensions based on the second image are within a predetermined threshold of the first dimensions of the item based on the first image, determine that the second dimensions are acceptable for computing dimensions of the item;
- and
- in response to determining that the second dimensions are not within a predefined threshold of the first dimensions of the item based on the first image, display the second image and second dimensions with a sign that indicates 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:
- capturing, by a camera, a first image of an item at a first time from a first perspective associated with a first position of the item, the first image comprising a view of at least two or more surfaces of the item;
- computing first dimensions of the item based on the first image;
- storing the first dimensions;
- capturing, by the camera, a second image of the item at a second time from a second perspective associated with a second position of the item, wherein the first perspective and second perspective are different, and the second image comprises a view of at least one of the two or more surfaces;
- computing second dimensions of the item based on the second image;
- comparing the second dimensions of the item computed based on the second image with the first dimensions of the item computed based on the first image;
- and
- in response to determining that the second dimensions are within a predefined threshold of the first dimensions of the item based on the first image, determining that the second dimensions are acceptable for computing dimensions of the item;
- and
- in response to determining that the second dimensions are not within a predefined threshold of the first dimensions of the item based on the first captured image, displaying the second dimensions and the second image with a sign that indicates the second dimensions of the item are inaccurate.
