1. A terminal for measuring at least one dimension of an object, comprising:
- a pixel array;
a range camera that projects a visible laser pattern of an outlined shape onto the object, the outlined shape corresponding to the range camera'"'"'s field of view;
a visible camera that produces a visible captured image of an area in which the object is located such that the outlined shape is within the visible camera'"'"'s field of view;
a processor, calculating from the visible image projected onto the pixel array, at least one divergence angle of the laser pattern, a number of pixels in the pixel array corresponding to the laser pattern, and at least one dimension of the object, wherein the divergence angle of the laser pattern is visible on the object and on the pixel array; and
a display connected to said processor, wherein the display presents information associated with an optimal orientation of the range camera and visible camera with respect to the object, and wherein;
the range camera'"'"'s field of view is narrower than the visible camera'"'"'s field of view; and
the display presents (i) the visible image produced by the visible camera and (ii) an outlined shape on the displayed visible image corresponding to the range camera'"'"'s field of view.

Abstract
A terminal for measuring at least one dimension of an object includes a range camera, a visible camera, and a display that are fixed in position and orientation relative to each other. The range camera is configured to produce a range image of an area in which the object is located. The visible camera is configured to produce a visible image of an area in which the object is located. The display is configured to present information associated with the range camera'"'"'s field of view and the visible camera'"'"'s field of view.

10. A terminal for measuring at least one dimension of an object, comprising:
-
a range camera that produces a range image of an area in which the object is located, said range camera also projecting a visible laser pattern onto the object, the laser pattern having an outlined shape corresponding to the range camera'"'"'s field of view; a visible camera that produces a visible captured image on a pixel array of an area in which the object is located such that the laser pattern is within the visible camera'"'"'s field of view; a processor calculating from the visible image at least one divergence angle of the laser pattern and a number of pixels in the pixel array corresponding to the laser pattern, the processor further calculating from an angle of an optical axis of the visible camera the at least one dimension of the object, wherein the divergence angle of the laser pattern is visible on the object and on the captured image; and a display connected to said processor, wherein the display presents information associated with the optimal orientation of the range camera and visible camera with respect to the object; wherein the range camera'"'"'s field of view is narrower than the visible camera'"'"'s field of view; and the display presents (i) the visible image produced by the visible camera and (ii) an outlined shape on the displayed visible image corresponding to the range camera'"'"'s field of view. - View Dependent Claims (11, 12, 13, 14)

15. A terminal for measuring at least one dimension of an object, comprising:
-
a range camera that produces a range image of an area in which the object is located, said range camera also projecting a visible laser pattern onto the object, the laser pattern having an outlined shape corresponding to the range camera'"'"'s field of view; a visible camera that produces a visible captured image on a pixel array of an area in which the object is located such that the laser pattern is within the visible camera'"'"'s field of view; a processor calculating, from the visible image, coordinates in a coordinate system, said coordinates corresponding to break points in the laser pattern on the object, and the processor further calculating the at least one dimension of the object, wherein the break points of the laser pattern are visible on the object and on the captured image; and a display; wherein the display presents information associated with (i) the range camera'"'"'s field of view and (ii) the visible camera'"'"'s field of view and (iii) the optimal orientation of the range camera and visible camera with respect to the object. - View Dependent Claims (16, 17, 18, 19, 20)
