## Abstract

A multi-dimensional measuring system is disclosed. The measuring system includes a dimensional measuring device that fits over an exterior portion of an item and provides reference measurements in three orthogonal directions. The measuring system also includes a camera to take an image of the item with the dimensional measuring placed thereon and a hardware processor that receives and processes the image to determine the dimensions of the item based upon the reference measurements of the dimensional measuring device.

## Claims

### Claim 1

A measuring device, comprising:
a first side having an inner surface;
a second side having an inner surface, the second side connected to the first side so that the inner surface of the second side is orthogonal to the inner surface of the first side;
a third side having an inner surface, the third side connected to the first and second sides so that the inner surface of the third side is orthogonal to the inner surfaces of the first and second sides; and
an interior corner formed at the intersection of the inner surfaces of the first, second, and third sides.

### Claim 2 (depends on 1)

The measuring device of claim 1, wherein a portion of each of the first and second sides forms an arm extending in an x-direction, a portion of each of the first and third sides forms an arm extending in a y-direction, and a portion of the second and third sides forms an arm extending in a z-direction, and wherein the x-, y-, and z-directions are each orthogonally oriented with respect to each other.

### Claim 3 (depends on 2)

The measuring device of claim 2, further comprising markings disposed on outer surfaces of the first, second, and third sides, the markings configured to delineate length measurements along a length of each arm, and wherein the markings are configured to provide length measurements measured from the interior corner in each of the x-, y-, and z-directions.

### Claim 4 (depends on 2)

### Claim 5 (depends on 2)

The measuring device of claim 2, wherein a length of each arm extending from the interior corner of the measuring device to an end of each arm is the same.

### Claim 6 (depends on 2)

The measuring device of claim 2, wherein each arm further comprises a high contrast marking at each end of each arm.

### Claim 7

A measuring system comprising:
a dimensional measuring device configured to fit over an exterior portion of an item and provide reference measurements in three directions;
a camera configured to capture an image of the item with the dimensional measuring device on the item; and
a hardware processor connected to the camera and configured to:
receive the image from the camera; and
determine the dimensions of the item based on the image and the reference measurements of the dimensional measuring device.

### Claim 8 (depends on 7)

The measuring system of claim 7, further comprising a scale that measures a weight of the item, wherein the scale is connected to the processor, and wherein the software receives the measured weight of the item.

### Claim 9 (depends on 8)

The measuring system of claim 8, further comprising a user terminal connected to the processor, the user terminal further comprising:
a display;
at least one of a keyboard, mouse, or touchscreen; and
