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.

Claims

1. A terminal for measuring at least one dimension of an object, comprising:

a range camera configured to produce a range image of an area in which the object is located;

a visible camera configured to produce a visible image of an area in which the object is located; and

a display;

wherein the range camera, visible camera, and display are fixed in position and orientation relative to each other; and

wherein the display is configured to present information associated with (i) the range camera'"'"'s field of view and (ii) the visible camera'"'"'s field of view.

2. The terminal according to claim 1, wherein:

the range camera'"'"'s field of view is narrower than the visible camera'"'"'s field of view; and

the display is configured to present (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.

3. The terminal according to claim 2, wherein the outlined shape is a rectangle.

4. The terminal according to claim 1, wherein the display is configured to present information associated with the optimal orientation of the range camera and visible camera with respect to the object.

5. The terminal according to claim 1, wherein the display is configured to present (i) the visible image produced by the visible camera and (ii) a symbol on the displayed visible image corresponding to the optical center of the range camera'"'"'s field of view.

6. The terminal according to claim 5, wherein the symbol comprises a crosshair target having three prongs.

7. The terminal according to claim 6, wherein:

the object is a rectangular box; and

the display is configured to show the three prongs of the crosshairs on the displayed visible image in an orientation that corresponds to the optimal orientation of the range camera and visible camera with respect to a corner of the rectangular box.

8. The terminal according to claim 1, wherein:

the object is cylindrically shaped having a medial axis; and

the display is configured to show (i) the visible image produced by the visible camera and (ii) a line on the displayed visible image in an orientation that corresponds to the optimal orientation of the range camera and visible camera with respect to the medial axis of the object.

9. The terminal according to claim 1, wherein:

the object is cylindrically shaped having a base; and

the display is configured to show (i) the visible image produced by the visible camera and (ii) an ellipse on the displayed visible image in an orientation that corresponds to the optimal orientation of the range camera and visible camera with respect to the base of the object.

10. A terminal for measuring at least one dimension of an object, comprising:

a range camera configured to produce a range image of an area in which the object is located;

a visible camera configured to produce a visible image of an area in which the object is located; and

a display;

wherein the range camera, visible camera, and display are fixed in position and orientation relative to each other;

wherein the range camera'"'"'s field of view is narrower than the visible camera'"'"'s field of view; and

the display is configured to present (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.

11. The terminal according to claim 10, wherein the outlined shape is a rectangle.

12. The terminal according to claim 10, wherein the display is configured to present information associated with the optimal orientation of the range camera and visible camera with respect to the object.

13. The terminal according to claim 10, wherein the display is configured to present (i) the visible image produced by the visible camera and (ii) a symbol on the displayed visible image corresponding to the optical center of the range camera'"'"'s field of view.

14. The terminal according to claim 13, wherein:

the object is a rectangular box;

the symbol comprises a crosshair target having three prongs; and

the display is configured to show the three prongs of the crosshairs on the displayed visible image in an orientation that corresponds to the optimal orientation of the range camera and visible camera with respect to a corner of the rectangular box.

15. A terminal for measuring at least one dimension of an object, comprising:

a range camera configured to produce a range image of an area in which the object is located;

a visible camera configured to produce a visible image of an area in which the object is located; and

a display;

wherein the display is configured to present information associated with (i) the range camera'"'"'s field of view and (ii) the visible camera'"'"'s field of view; and

wherein the display is configured to present information associated with the optimal orientation of the range camera and visible camera with respect to the object.

16. The terminal according to claim 15, wherein:

the range camera'"'"'s field of view is narrower than the visible camera'"'"'s field of view; and

the display is configured to present (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.

17. The terminal according to claim 16, wherein the outlined shape is a rectangle.

18. The terminal according to claim 15, wherein the display is configured to present (i) the visible image produced by the visible camera and (ii) a symbol on the displayed visible image corresponding to the optical center of the range camera'"'"'s field of view.

19. The terminal according to claim 15, wherein:

the object is cylindrically shaped having a medial axis; and

the display is configured to show (i) the visible image produced by the visible camera and (ii) a line on the displayed visible image in an orientation that corresponds to the optimal orientation of the range camera and visible camera with respect to the medial axis of the object.

20. The terminal according to claim 15, wherein:

the object is cylindrically shaped having a base; and

the display is configured to show (i) the visible image produced by the visible camera and (ii) an ellipse on the displayed visible image in an orientation that corresponds to the optimal orientation of the range camera and visible camera with respect to the base of the object.
