Abstract: A method for detecting, on the finish of containers, defects in a horizontal mold seal of the container includes the steps of disposing the container between a light source and a camera and ensuring the rotation of the container on itself according to one rotational revolution. The camera acquires, at each increment of rotation of the container, an image so that the number of images per rotational revolution is greater than 36. The images captured for each container are analyzed such that the profile of the finish edge is detected in each image, the profiles of the finish edge of the images are compared with a reference profile of the finish edge so as to detect deviations between these profiles, and a defect in the horizontal mold seal for a container is detected when at least one image of said container has a deviation.

Abstract: The invention relates to a method, a device and an inspection line for determining the three-dimensional geometry of a container ring surface, including the formation, by two optical systems (24, 24′), of two images of the ring surface of the container, according to two peripheral observation fields having a first and a second observation elevation angle (γ1, γ2) different from each other.
