Abstract

A three-dimensional (3D) measurement system and method is provided. The system includes a noncontact measurement device, an annotation member and a processor. The noncontact measurement device being operable to measure a distance from the noncontact measurement device to a surface. The annotation member is coupled to the noncontact measurement device. The processor is operably coupled to the noncontact measurement device and the annotation member, the processor operable to execute computer instructions when executed on the processor for determining 3D coordinates of at least one point in a field of view based at least in part on the distance, recording an annotation in response to an input from a user, and associating the annotation with the at least one point.

First claim

What is claimed is:

1. A three-dimensional (3D) measurement system comprising:
a noncontact measurement device operable to measure a distance from the noncontact measurement device to a surface;
an annotation member coupled to the noncontact measurement device;
a laser light source arranged to emit a visible light beam from the noncontact measurement device; and
a processor operably coupled to the noncontact measurement device and the annotation member, the processor operable to execute computer instructions when executed on the processor for determining 3D coordinates of a first point in a field of view based at least in part on the distance, recording an annotation received from a user, and associating the annotation with the first point;
wherein the processor is further operable to execute the computer instructions to perform a method comprising:
highlighting, by the 3D measurement system the first point on the surface by emitting, by the laser light source, from a first position of the 3D measurement system, the visible light beam onto said first point;
locking, by the laser light source, the first point on the surface, in response to an input from the user; and
in response to the 3D measurement system moving to a second position, maintaining the highlight of the first point on the surface by emitting the visible light beam onto the first point from the second position of the 3D measurement system.

2. The system of claim 1 , wherein the annotation member is a microphone arranged to receive sounds from the user.

3. The system of claim 2 , wherein the microphone includes a plurality of microphones, each of the plurality of microphones being coupled to the noncontact measurement device and arranged to receive sound from a different direction.

4. The system of claim 3 , wherein the processor is further operable to determine a direction that the sound is generated based on signals from the plurality of microphones.

5. The system of claim 2 , wherein the processor is further operable to execute a process on the noncontact measurement device in response to a sound received by the microphone from the user.

6. The system of claim 1 , wherein the processor is further operable to perform a method comprising:
in a first instance emitting the visible light beam onto the first point in response to a first input from the user;
in a second instance emitting the visible light beam onto a second point in response to a second input from the user; and
comparing measurement data around the first point and the second point based at least in part on the 3D coordinates of the first point and the second point.

7. The system of claim 1 , wherein the noncontact measurement device includes a camera with the field of view, and wherein the processor is further operable to perform a method comprising:
emitting the visible light beam onto a surface in response to an input from the user;
acquiring an image of the surface with a spot of light from the visible light beam; and
determining 3D coordinates of the spot of light on the surface based at least in part on a baseline distance between the camera and the laser light source.

8. The system of claim 1 , wherein the annotation member further includes a microphone, and wherein the processor is further operable to perform a method comprising:
emitting the visible light beam onto a surface in response to the input from the user;
acquiring an image of the surface with a spot of light from the visible light beam;
recording a sound from the user; and
associating the recording of the sound with the image.

9. The system of claim 1 , wherein the noncontact measurement device includes a camera with the field of view, and wherein the processor is further operable to perform a method comprising:
emitting the visible light beam onto a surface in response to the input from the user;
acquiring an image of the surface with a spot of light from the visible light beam; and
receiving a computer-aided design (CAD) model of an object being scanned; and
defining a reference point on the CAD model based at least in part on the image.

10. The system of claim 1 , wherein the noncontact measurement device includes a camera with the field of view, and wherein the processor is further operable to perform a method comprising:
defining a reference point in a computer-aided-design model; and
emitting the visible light beam onto a feature of an object in response to the input from the user, the feature being based at least in part on the reference point.

11. A method comprising:
acquiring point data about a plurality of points on a surface with a noncontact measurement device;
determining 3D coordinates of the plurality of points based at least in part on the point data;
in a first instance, recording annotation data with an annotation member in response to an input from a user, the annotation member being coupled to the noncontact measurement device;
associating, interactively, the annotation data with at least a portion of the 3D coordinates of points, wherein the portion of the 3D coordinates of points were determined from the point data acquired contemporaneously with the annotation data, wherein the associating comprises:
highlighting the portion of the 3D coordinates by emitting, by a laser light source, from a first position of the noncontact measurement device, a visible light beam onto a first point from the portion of the 3D coordinates;
locking the first point, in response to the input from the user; and
in response to the noncontact measurement device moving to a second position, maintaining the highlight of the first point by emitting the visible light beam onto said first point from the second position of the noncontact measurement device.

12. The method of claim 11 , wherein the annotation member includes a microphone and the recording of annotation data includes recording sound data.

13. The method of claim 12 , wherein the sound data includes an operator's voice.

14. The method of claim 12 , wherein the annotation member includes a plurality of microphones, each of the microphones arranged to receive sound from a different direction.
