The invention concerns a three-dimensional measuring device, which comprises: a base (5) intended to be fixed to a support assembly (6) and lying in a first plane, a plate (14) mounted so as to rotate on the base (5) about a first axis (Z), said plate being equipped with a first sensor (c1) determining the angle of rotation (Φ) of the plate about this first axis (Z), a single rocking telescopic arm (2), a first end of which is articulated on the plate (14) about a second axis (X) orthogonal to the first axis (Z), the angle of rotation (&thetas;) of said arm about the second axis (X) being determined by a second sensor (c2), the second end of the single telescopic arm being provided with a measuring feeler (3), and the said single arm being equipped with a third sensor (c3) determining the elongation length (&rgr;) of the arm in translation, so that the spatial position of the measuring feeler is determined by its polar coordinates (&rgr;, &thetas;, Φ) in the fixed three-dimensional reference frame consisting of the base (5) once the latter is fixed to the support assembly (6). |
