A noncontact optical three-dimensional measuring device that includes a projector, a first camera, and a second camera; a processor electrically coupled to the projector, the first camera 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. |

1. A noncontact optical three-dimensional measuring device comprising:
an assembly that includes a projector, a first camera, and a second camera, wherein the projector, the first camera, and the second camera are fixed in relation to one another, there being a first distance between the projector and the first camera and a second distance between the projector and the second camera, the projector having a light source, the projector configured to emit onto a surface of an object a first light having any of a plurality of patterns, the first camera having a first lens and a first photosensitive array, the first camera configured to receive a first portion of the first light emitted from the projector and reflected off the surface and to produce a first digital signal in response, the first camera having a first field of view, the first field of view being a first angular viewing region of the first camera, the second camera having a second lens and a second photosensitive array, the second camera configured to receive a second portion of the first light emitted from the projector and reflected off the surface and to produce a second digital signal in response, the second camera having a second field of view, the second field of view being a second angular viewing region of the second camera, the second field of view being different than the first field of view; and a processor, electrically coupled to the projector, the first camera, and the second camera, that executes a computer executable program code that when executed by the processor performs operations that include causing 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, determining 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 determining three-dimensional coordinates of a second point on the surface based at least in part on the second digital signal and the second distance. |
