Abstract

A mobile dimensioning device, i.e. a mobile dimensioner, is described that uses a dynamic accuracy while still being compatible with the NIST standard. Even if the accuracy division is dynamic and not predetermined, a mobile dimensioning device of the present invention reports the actual dimensioning prior to measurement capture and can therefore be certified and used in commercial transactions.

Claims

1. A device, comprising:

a display;

non-volatile storage;

one or more sensors;

an input subsystem;

one or more processors;

and memory containing instructions executable by the one or more processors whereby the device is operable to;

display, on the display, an object to be measured by the one more sensors;

derive one or more accuracy parameters based on information received from the one or more sensors for a measurement environment of the object being measured;

compute an accuracy level based on the one or more accuracy parameters;

determine if the accuracy level corresponds to a sufficient measurement environment;

if the accuracy level corresponds to the sufficient measurement environment;

display, on the display along with the object, an indication that the measurement environment is sufficient and a capture icon to enable capture of dimensions of the object;

in response to an input received at the capture icon, capture the dimensions of the object;

display, on the display along with the object, at least the dimensions of the object; and

record the dimensions of the object.

2. The device of claim 1, wherein the accuracy level is an accuracy division as defined by the National Institutes of Standards and Technology (NIST) standard.

3. The device of claim 1, wherein the one or more accuracy parameters comprise at least one of a group consisting of:

distance to the object, viewing angle relative to the object, temperature, ambient light, and quality of data from the one or more sensors.

4. The device of claim 1, wherein the one or more sensors comprise at least one of a group consisting of:

optical sensors and measurement sensors.

5. The device of claim 4, wherein the optical sensors are selected from a group consisting of:

a barcode sensor, a camera, and an image sensor.

6. The device of claim 4, wherein the measurement sensors are selected from a group consisting of:

point-cloud projection, structured light, and stereoscopic cameras and n-scopic cameras.

7. The device of claim 2, wherein the sufficient measurement environment is an environment where the accuracy division has a low lower than a predetermined threshold.

8. The device of claim 1, wherein displaying, on the display, an indication that the measurement environment is sufficient comprises at least one of a group consisting of:

displaying an accuracy division, displaying a completed progress bar, and displaying a confirmation icon.

9. The device of claim 1, wherein displaying, on the display, the dimensions of the object comprises displaying the dimensions of the object and a corresponding accuracy divisions.

10. The device of claim 1, wherein computing an accuracy level based on the one or more accuracy parameters comprises running multivariable regression on the one or more accuracy parameters.

11. The device of claim 1, wherein the dimensions of the object and the accuracy level are stored in the non-volatile storage.

12. The device of claim 11, wherein the device is further operable to:

determine that the object being measured has been previously measured; and

retrieved the dimensions of the object and the accuracy level from the non-volatile storage;

display, on the display, the dimensions of the object and the accuracy level from the non-volatile storage; and

record the dimensions of the object and the accuracy level from the non-volatile storage.

13. The device of claim 1, wherein the device is further operable to:

if the accuracy level does not correspond to a sufficient measurement environment;

provide an indication for improving the measurement environment.

14. The device of claim 13, wherein the indication for improving the measurement environment comprises at least one of a group consisting of:

a textual instruction, a graphical instruction, and a graphical icon.

15. The device of claim 13, wherein the indication for improving the measurement environment comprises at least one of a group consisting of:

an indication for shortening a distance to the object, an indication for improving a viewing angle relative to the object, an indication to delay measurement pending a target operating temperature, and indication for improving an ambient light, and an indication for adjusting the one or more sensors to improve a quality of data.
