Abstract: A method is described of updating a parametric model used to characterise the geometry of a coordinate positioning machine. A length-measuring device is coupled between a first point that is fixed relative to a moveable part of the machine and a second point that is fixed relative to a fixed part of the machine, the length-measuring device being adapted to measure a separation between the first and second points. The machine is controlled into a plurality of different poses, in each of which poses the moveable part of the machine is in a different position and/or orientation relative to the fixed part of the machine. For each of the plurality of different poses, a measurement from the length-measuring device of the separation between the first and second points is recorded, and an error value is determined based on the recorded separation and a separation expected from an existing set of model parameters for the parametric model. An overall error measure is determined from the error values, and a new set of model parameters for the parametric model is determined that would result in a lower overall error measure than for the existing set of model parameters, the new set of model parameters.
