1. A system for dimensioning items or spaces, comprising:
- a two-dimensional imaging optical device having range finding capability; and
a processor and a memory associated with the optical device, wherein the memory stores calibration information related to dimensions of a full field of view of the optical device for a given distance to an object;
wherein the optical device is operable to acquire an image of the item or space to be dimensioned, and to communicate with the processor so that the processor computes the dimensions of the item or space using the range finding capability and the calibration information.

Abstract
A system and method are described for determining the dimensions of items using an optical device, such as a barcode and/or RFID tag reader, for example. The dimensions of the field of view of the optical device are established, indexed by distance, and the dimensions of items in the field of view of the optical device are determined as a percentage of the full field of view of the optical device at the appropriate distance.

7. A method of dimensioning an item or space, comprising:
-
aiming a two-dimensional imaging optical device toward the item or space to be dimensioned such that the item or space is in the field of view of the optical device; determining a distance from the optical device to the item or space to be dimensioned; capturing an image of the item or space with the optical device; and computing the dimensions of the item or space based on the relative field of view occupied by the item or space and stored calibration information for the distance from the optical device to the item or space being dimensioned. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A system for reading RFID tags, comprising:
-
a two-dimensional imaging optical device that provides an image of an item or space; a range-finding component that determines a distance from the optical device to the item or space; an RFID interrogator that reads RFID tag data; and a processor and a memory, the processor being operable to compute dimensions of the item or space based on the image of the item or space and the distance from the optical device to the item or space, and to relate the RFID tag data to the dimensions of the item or space. - View Dependent Claims (17, 18, 19)
