Abstract

Systems and methods for volume dimensioning packages are provided. A method of operating a volume dimensioning system may include the receipt of image data of an area at least a first three-dimensional object to be dimensioned from a first point of view as captured using at least one image sensor. The system can determine from the received image data a number of features in three dimensions of the first three-dimensional object. Based at least on part on the determined features of the first three-dimensional object, the system can fit a first three-dimensional packaging wireframe model about the first three-dimensional object. The system can display of an image of the first three-dimensional packaging wireframe model fitted about an image of the first three-dimensional object on a display device.

Claims

1. A method for fitting a packaging wireframe model to one or more three-dimensional objects, the method comprising:

receiving image data of an area from a first point of view by at least one nontransitory processor-readable medium from at least one image sensor, the area including at least a first three-dimensional object to be dimensioned;

determining that there are insufficient features on the first three-dimensional object to select one or more geometric primitives that are representative of the first three-dimensional object to the packaging wireframe model; and

in response to the determination, generating an output to obtain additional features on the first three-dimensional object from a second point of view in order to select one or more geometric primitives that are representative of the first three-dimensional object to fit to the packaging wireframe model, the second point of view different from the first point of view.

2. The method of claim 1, wherein generating the output to obtain the additional features on the first three-dimensional object from the second point of view comprises generating at least one output comprising an audio output that is perceivable by a user.

3. The method of claim 2, wherein the at least one output indicates to the user a direction of movement of the at least one image sensor with respect to the first three-dimensional object.

4. The method of claim 1, wherein generating the output to obtain the additional features on the first three-dimensional object from the second point of view comprises generating at least one output comprising a visual output that is perceivable by a user.

5. The method of claim 4, wherein the at least one output indicates to the user a direction of movement of the at least one image sensor with respect to the first three-dimensional object.

6. The method of claim 1, wherein the packaging wireframe model is two-dimensional and is fitted about a portion of an image of the first three-dimensional object, the method further comprising displaying an image of the packaging wireframe model on a display on which the image of the first three-dimensional object is displayed.

7. The method of claim 6, wherein displaying of the image of the packaging wireframe model occurs before generating the output.

8. The method of claim 1, comprising determining, from the received image data, a number of features in three dimensions of the first three-dimensional object by at least one processor communicatively coupled to the at least one nontransitory processor-readable medium, wherein the features comprise one of corners, arcs, lines, edges, angles, and radii associated with an external boundary of the first three-dimensional object.

9. The method of claim 8, further comprising, based at least in part on the determined features of the first three-dimensional object, displaying an image of the packaging wireframe model, wherein the packaging wireframe model is two dimensional and is fitted about a portion of an image of the first three-dimensional object, on a display on which the image of the first three-dimensional object is displayed.

10. The method of claim 9, wherein displaying the image of the packaging wireframe model occurs before generating the output.

11. A volume dimensioning system, comprising:

at least one image sensor communicably coupled to at least one nontransitory processor-readable medium;

at least one processor communicably coupled to the at least one nontransitory processor-readable medium; and

a machine executable instruction set stored within at least one nontransitory processor-readable medium, that when executed by the at least one processor causes the at least one processor to;

read image data from the at least one nontransitory processor-readable medium, the image data associated with a first point of view of an area sensed by the at least one image sensor, the area including at least a first three-dimensional object to be dimensioned;

determine from the received image data that there are an insufficient number of features on the first three-dimensional object to select one or more geometric primitives that are representative of the first three-dimensional object to the packaging wireframe model;

responsive to the determination of an insufficient number of features in the image data, generate an output to obtain additional features on the first three-dimensional object from a second point of view in order to select one or more geometric primitives that are representative of the first three-dimensional object to fit to the packaging wireframe model, the second point of view different from the first point of view.

12. The volume dimensioning system of claim 11, wherein the machine executable instruction set comprises instructions that when executed by the at least one processor cause the at least one processor to:

generate an audio output that is perceivable by a user to obtain the additional features on the first three-dimensional object from the second point of view.

13. The volume dimensioning system of claim 12, wherein the audio output indicates to the user a direction of movement the at least one image sensor with respect to the first three-dimensional object.

14. The volume dimensioning system of claim 11, wherein the machine executable instruction set comprises instructions that when executed by the at least one processor cause the at least one processor to:
