Abstract: An in-line method for optically inspecting transparent or translucent containers (3) comprises illuminating each container with a light source that presents light intensity variation in a periodic pattern along at least a first variation direction. A number N greater than or equal to three of images of the container traveling in front of the light source and occupying N different respective positions along the travel path is taken. Between taking successive images, a relative shift between the container and the periodic pattern is created. A geometrical transformation is determined and applied in order to put the pixels belonging to the container in the N successive images of the same container into coincidence. A phase image for each container is constructed using the N registered images of the container. The phase image is analyzed in order to deduce therefrom at least the presence of defects or the quality of the container.

Abstract: A method of inspecting articles of transparent/translucent material with a vision system comprises illuminating the articles with a light source having an angular spectrum that is adapted to the contrast selected for refractive items presented by the articles. An image sensor picks up the light that has passed through the articles to make images of the articles. During a stage of referencing the vision system, a reference standard is in the field of view of the image sensor, the standard including at least one standard item that refracts light in a known range of angles. An image of the standard is taken to measure at least the contrast in the image produced by at least one standard item. During at least one stage of qualifying the vision system, the standard is placed once more in front of the light source and in the field of view of the image sensor.

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.
