This paper uses the coordinate measuring machine as the workhorse and develops an alignment procedure for the point laser triangulation probe. We align the orientation of laser probe by phase correlation method and calibrate the reference position of it by using a pyramid artifact. Additionally, the gradient of the surface of pyramid artifact will introduce errors when measured by laser probe. In order to verify the effect of the gradients of the surface of pyramid artifact, we place a inclination adjustable non-specular block gauge on a rotatable platform to form different gradient of the surface of the pyramid artifacts. Finally, we had discussed and analyzed the errors caused by gradient of the surface of pyramid artifact when measured by laser probe for aligning the orientation of laser probe, and decided the optimal surface orientation of pyramid artifact design.
