Abstract
A geometrical model of a multi-axis robot equipped with a camera () comprises a first change matrix (T) and a second change matrix T)). A method for adjusting the model comprises: aiming (), with the camera arranged in a first location (k1), at at least two points among L points of the target; determining the coordinates of each point aimed at; moving () the camera; d) aiming (), with the camera arranged in a second location (k2), at the same points (P); determining the coordinates of each point aimed at; calculating (), for each point aimed at, a difference of the difference (v) between the coordinates nt in a base coordinate frame (BF), expressed in using the first and second change matrix calculating () an overall difference value (F, G). Variables (X-X, Δα, Δι, Δθ, Δr) of coefficients of the first and second change matrices (T, T) are determined by minimizing () the overall value calculated during step g). The camera is successively brought into K locations. The product of the number (L) of points of the target by the number (K) of locations minus 6 (L*K−6) is greater than or equal to the number of variables of the geometrical model of the multi-axis robot.
