Abstract

A 3D sensor system with a mounting arrangement is provided. The system includes a 3D sensor that measures 3D coordinates of a surface, the 3D sensor having a body with a slot disposed in a side, the slot further having a recess centrally disposed thereon. One or more slot nuts are disposed in the slot. A mounting bracket is provided having a pair of keystone members and a dowel pin disposed therebetween, the keystone members being disposed in the slot and the dowel pin being disposed in the recess, the mounting bracket having a plurality of holes aligned with the slot. One or more fasteners are provided that extend through the plurality holes and engage the one or more slot nuts to couple the mounting bracket to the 3D sensor.

First claim

What is claimed is:

1. A 3D sensor system comprising:
a 3D sensor that measures 3D coordinates of a surface, the 3D sensor having a body with a first slot disposed in, and extending along a length of, a first side, the slot further having a first semi-circular recess centrally disposed along the length of the first side, the 3D sensor having at least one projector and at least one camera disposed within the body;
one or more slot nuts disposed in the slot;

a planar mounting bracket removably coupled to the 3D sensor, the mounting bracket having a pair of keystone members and a dowel pin disposed therebetween, the pair of keystone members and the dowel pin extending from a side of the mounting bracket, the keystone members being disposed in the first slot and the dowel pin being disposed in the first recess, the mounting bracket having a plurality of holes aligned with the first slot; and
one or more fasteners extending through the plurality holes and engaging the one or more slot nuts to couple the mounting bracket to the 3D sensor.

2. The sensor system of claim 1 , wherein the 3D sensor includes a second slot disposed in a second side.

3. The sensor system of claim 2 , wherein the second side is oriented 90 degrees to the first side.

4. The sensor system of claim 1 , wherein the mounting bracket includes a plurality of recesses on a side opposite the 3D sensor.

5. The sensor system of claim 4 , wherein the mounting bracket is an elongated planar member.

6. The sensor system of claim 5 , wherein the dowel is disposed half-way between the pair of keystone members.

7. The sensor system of claim 6 , wherein the mounting bracket further includes a pair of mounting holes positioned adjacent the ends of the mounting bracket, the pair of mounting holes extending therethrough.

8. The sensor system of claim 7 , wherein the plurality of holes includes a plurality of sensor mounting holes that extend therethrough.

9. The sensor system of claim 8 , wherein the plurality of sensor mounting holes includes a first pair of sensor mounting holes, a first of the pair of keystone members being disposed between the first pair of sensor mounting holes.

10. The sensor system of claim 9 , wherein the plurality of sensor mounting holes includes a second pair of sensor mounting holes, a second of the pair of keystone members being disposed adjacent the second pair of sensor mounting holes.

11. The sensor system of claim 1 , wherein the first slot is defined by a pair of arms that define a channel.

12. The sensor system of claim 11 , wherein the slot nuts are movably disposed within the channel.

13. The sensor system of claim 12 , wherein each of the pair of arms includes a plurality of dimples or recesses spaced apart a predetermined distance.

14. The sensor system of claim 13 , wherein the slot nuts includes a spring loaded sphere that cooperates with the plurality of dimples or recesses to facilitate positioning of the slot nuts.

15. The sensor system of claim 14 , wherein the predetermined distance is 25 millimeters.

16. The sensor system of claim 1 , wherein the 3D sensor includes a third side, the third side having a plurality of Ethernet connectors thereon.

17. The sensor system of claim 16 , wherein the 3D sensor includes a projector and at least one camera disposed on a fourth side opposite the first side.
