3D laser scanner become popular in manufacturing
field because of its capability in measuring various characteristics
of part and reverse engineering. It is found that laser scanner which
categorize under non-contact method is less accurate compared to
the contact method. This is due to the output quality that depending
on digitizing points captured during scanning. These digitizing
points are affected from extrinsic and intrinsic parameters. Some of
the parameters for commercial lasers are already calibrated prior
to delivery. In this paper, extrinsic parameters are discussed based
on LC15 laser scanner with Metris scan 4.1 software. A suggestion
on model of uncertainty is suggested based on propagation of
uncertainty method align with the understanding of extrinsic
scanning parameters
