THREE-DIMENSIONAL COORDINATE SCANNER AND METHOD OF OPERATION
First Claim
1. A noncontact optical three-dimensional measuring device comprising:
- an assembly that includes a first projector, a first camera, a second projector and a second camera, the first projector having a first light source operable to emit onto a surface of an object a first light having at least one pattern, the second projector having a second light source operable to emit onto the surface of the object a second light;
one or more processors for executing computer readable instructions, the computer readable instructions comprising;
acquiring with the first camera a first image of a first portion of the first light;
determining three-dimensional coordinates of a first point on the surface based at least in part on the first image;
determining the presence of a multipath interference based at least in part on the first image;
causing the assembly to move from a first position to a second position in response to determining the presence of multipath interference;
acquiring with the second camera a second image of a second portion of the second light in response to moving the assembly from the first position to the second position; and
determining three-dimensional coordinates of a second point on the surface based at least in part on the second image.

Abstract
A noncontact optical three-dimensional measuring device that includes a first projector, a first camera, a second projector, and a second camera; a processor electrically coupled to the first projector, the first camera, the second projector, and the second camera; and computer readable media which, when executed by the processor, causes the first digital signal to be collected at a first time and the second digital signal to be collected at a second time different than the first time and determines three-dimensional coordinates of a first point on the surface based at least in part on the first digital signal and the first distance and determines three-dimensional coordinates of a second point on the surface based at least in part on the second digital signal and the second distance.

9. A method of determining three-dimensional coordinates on a surface of an object, the method comprising:
-
providing an assembly that includes a first projector, a first camera, a second projector and a second camera, the first projector having a first light source operable to emit onto a surface of an object a first light having at least one pattern, the second projector having a second light source, the second projector operable to emit onto the surface of the object a second light; acquiring with the first camera a first image of a first area of the surface; determining with one or more processors three-dimensional coordinates of a first point on the surface based at least in part on the first image; determining with the one or more processors the presence of a multipath interference based at least in part on the first image; moving the assembly from a first position to a second position in response to determining the presence of multipath interference; acquiring with the second camera a second image of a second area of the surface in response to moving the assembly from the first position to the second position; and determining with the one or more processors three-dimensional coordinates of a second point on the surface based at least in part on the second image. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
