1. A portable coordinate measurement machine (CMM) for measuring the position of an object in a selected volume, comprising:
- a manually positionable articulated arm having opposed first and second ends, said arm including a plurality of jointed arm segments, each arm segment including at least one position transducer for producing a position signal;
a laser scanner at said first end of said arm;
an electronic circuit which receives the position signals from the transducers and provides a digital coordinate corresponding to the position of the first end of said arm in a selected volume;
at least one internally positioned bus within said articulated arm for internally transmitting at least one of power and data signals to said laser scanner, said laser scanner including circuitry communicating with said at least one bus.

27. A portable coordinate measurement machine (CMM) for measuring the position of an object in a selected volume, comprising:
-
a manually positionable articulated arm having opposed first and second ends, said arm including a plurality of jointed arm segments, each arm segment including at least one position transducer for producing a position signal; a laser scanner at said first end of said arms, said laser scanner including a laser, a camera and on-board image processing circuitry; an electronic circuit which receives the position signals from the transducers and provides a digital coordinate corresponding to the position of the first end of the arm in a selected volume; at least one bus internally positioned within said articulated arm for internally transmitting power and data signals to said laser line scanner, said laser scanner including circuitry communicating with said at least one bus; and wherein said on-board image processing circuitry comprises; a digital interface communicating with said camera; a digital signal processor (DSP) communicating with said digital interface for processing images from said scanner and converting image data to dimensional data, said DSP further generating processed data, such processed data being in an amount which is smaller than the amount of data associated with the original data derived from the image received from the camera; a memory communicating with said DSP; and a communications processor communicating with said DSP. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
