Method and device for we shall now describe, for the treatment of sequences of images, defects reflective the application and presented by a transparent hollow

摘要

The process according to the invention is to detect defects (8), which reflects the light and presented by a hollow object (2) which is transparent or translucent. According to the invention, the method consists of: to illuminate a region of the hollow object (2) by at least an incident beam (6),.. to ensure the relative rotation with respect to the incident beam of the hollow object according to its central axis (4), to acquire and to treat the reflected light beams (7) by the object, in order to determine whether or not the object has a defect,.. on the basis of the light beams reflected by the object, to form successive images of the object according to a given speed, and to carry out an operation of the comparison between at least two successive images, so as to distinguish between the beams reflected in nature, corresponding to the parasitic reflections, those of a nature that is variable in time and the space corresponding to the defects of the object.
