Item collection guidance system

1. A method, comprising:

obtaining, by a processor, a task definition including (i) an item identifier, (ii) an original item quantity, and (iii) a normalized item quantity;

presenting, by the processor, the item identifier and the normalized item quantity;

obtaining, by the processor, an image of a collected item set;

deriving, by the processor, collected item data from the image, the collected item data being indicative of, for each item of the collected item set, (i) a collected item identifier, (ii) a collected item size, (iii) a collected item weight, and (iv) a collected item count;

determining, by the processor, whether the collected item data matches the item identifier and the original item quantity;

in response to determining the collected item data matches the item identifier and the original item quantity, generating, by the processor, first output data; and

in response to determining-does not match the item identifier and the original item quantity, generating, by the processor, second output data.

2. The method of claim 1 , further comprising:

prior to obtaining the task definition, obtaining, by the processor, order data including the item identifier and the original item quantity; and

generating, by the processor, the normalized item quantity.

3. The method of claim 2 , wherein generating the normalized item quantity includes:

retrieving an item attribute based on the item identifier; and

generating the normalized item quantity based on the original item quantity and the item attribute.

4. The method of claim 1 , wherein obtaining the task definition includes receiving the task definition from a server at a mobile computing device.

5. The method of claim 1 , further comprising: determining, by the processor, a collected item quantity from the collected item count.

6. The method of claim 1 , wherein the first output data includes a collection status indicator.

7. The method of claim 1 , wherein the second output data includes an error message indicating a mismatch between the task definition and the collected item data.

8. The method of claim 1 , wherein obtaining the image includes controlling an image sensor to capture the image; and

wherein deriving the collected item data includes detecting items from the image.

9. A computing device, comprising:

an image sensor;

an output assembly; and

a processor configured to:

obtain a task definition including (i) an item identifier, (ii) an original item quantity, and (iii) a normalized item quantity;

present the item identifier and the normalized item quantity via the output assembly;

obtain an image of a collected item set via the image sensor;

derive collected item data from the image, the collected item data being indicative of, for each item of the collected item set, (i) a collected item identifier, (ii) a collected item size, (iii) a collected item weight, and (iv) a collected item count;

determine whether the collected item data matches the item identifier and the original item quantity;

in response to determining the collected item data matches the item identifier and the original item quantity, generate first output data; and

in response to determining the collected item data does not match the item identifier and the original item quantity, generate second output data.

10. The computing device of claim 9 , wherein the processor is further configured to:

prior to obtaining the task definition, obtain order data including the item identifier and the original item quantity; and

generate the normalized item quantity.

11. The computing device of claim 10 , wherein the processor is configured, in order to generate the normalized item quantity, to:

retrieve an item attribute based on the item identifier; and

generate the normalized item quantity based on the original item quantity and the item attribute.

12. The computing device of claim 9 , wherein the processor is configured, in order to obtain the task definition, to receive the task definition from a server.

13. The computing device of claim 9 , wherein the processor is further configured to: determine a collected item quantity from the collected item count.

14. The computing device of claim 9 , wherein the first output data includes a collection status indicator.

15. The computing device of claim 9 , wherein the second output data includes an error message indicating a mismatch between the task definition and the collected item data.

16. The computing device of claim 9 , wherein the processor is further configured, in order to derive the collected item data, to detect items from the image.

17. A non-transitory computer-readable medium storing instructions executable by a processor of a computing device to:

obtain a task definition including (i) an item identifier, (ii) an original item quantity, and (iii) a normalized item quantity;

present the item identifier and the normalized item quantity via an output assembly;

obtain an image of a collected item set via an image sensor;

derive collected item data from the image, the collected item data being indicative of, for each item of the collected item set, (i) a collected item identifier, (ii) a collected item size, (iii) a collected item weight, and (iv) a collected item count;

determine whether the collected item data matches the item identifier and the original item quantity;

in response to determining the collected item data matches the item identifier and the original item quantity, generate first output data; and

in response to determining the collected item data does not match the item identifier and the original item quantity, generate second output data.
