By using homogenous coordinate transformation principle and Denavit-Hartenberg analysis method, a measurement kinematics model and a error model to arbitrary point of automobile panels in normal mechanical parameter measurement instrument, which the movement of the probe center is relative to machine reference frame is construct. On the basis of using wielding matrix function total differential method, building up the error delivery relation of parameter error of measuring motion model transform to the probe center, and having verified what be built the error model correctness by simulation. The error is enlarge mainly in the process of delivery from angle error, while length error are very minor in error effects. This research can establish a base for studying the measuring-error of portable type measures instrument and it's measuring accuracy.
