Abstract
A method for measuring verticality of a container having a base and vertical wall comprises measuring at each rotational position of the container, at least the position along a first measurement axis, of at least one first measuring point located on the base, and a second measuring point located on the base diametrically opposite to the first measuring point, the position along a third measurement axis, of at least one third measuring point located on the vertical wall at a distance from the base. An angle defined between a first segment passing through the first and second measuring points and a second segment intersecting the first segment and passing through at least the third measuring point is selected to be representative of the container verticality. For each rotational position of the container, a quantity depending on the angle is calculated. Verticality is measured from the variations of the calculated quantity.
