1. A method of determining the capacity of glass containers (1), the method comprising the following steps:using an X-ray computed-tomography apparatus (10) to acquire a plurality of X-ray images (I) of the container at different projection angles;
transmitting the X-ray images to a computer (17); and
analyzing the X-ray images with the computer;
the method being characterized by:
acquiring the X-ray images (I) for an empty container in order to cause only the material of the container to appear in the X-ray images;
determining the support surface of the container; and
analyzing the X-ray images in order to:
construct a digital model (M) of the container from the X-ray images;
determine the inside surface (Sf) of the digital model of the container;
position a filling level plane (Pn) on the digital model of the container parallel to the support surface and at a nominal distance (Hn) from the top of the digital model of the container; and
