Abstract
A portable coordinate measuring machine for measuring the coordinates of an object in space is provided including a manually positionable articulated arm portion having a plurality of connected arm segments that include position transducers that provide position signals. A probe assembly connected to an arm segment includes a non-contact measurement device having a projector and a camera separated by a baseline distance. The projector includes a light source that emits a line of light. The camera includes an image sensor having an array of pixels that receives the light reflected from the object in a sensor plane. A first processor of the camera, coupled to the image sensor, determines centroids from the received light. A second processor coupled to the first processor determines three-dimensional coordinates of points on the object based at least in part on the centroids provided by the processor, the positions, and the baseline distance.
