Abstract

The object of the application is a measuring method for geometrical parameters of a tobacco industry's multi-segment rod-like article (1, 1′, 1″), by means of a beam of electromagnetic radiation (6A) directed at the article (1, 1′, 1″), characterised in that by means of a radiation receiving device (7) a radiation (7A) emitted by the tobacco industry's multi-segment article (1, 1′, 1″) under the influence of excitation induced by the radiation (6A) directed at the tobacco industry's multi-segment article (1, 1′, 1″) is received, and a signal (32) corresponding to the received radiation (7 A) is generated. Furthermore, in the radiation receiving device (7) or using processing means (33) in the control system (30) of such device the signal (32) corresponding to the radiation (7A) received by the radiation receiving device (7) is processed and on the basis thereof an image (P, P′, P″) corresponding to the view of the multi-segment article (1, 1′, 1″) is created. Then, with the use of the processing means (33), based on the difference in intensity of the radiation (7A) emitted by the tobacco industry's multi-segment article (1, 1′, 1″) visible in the created image (P, P′, P″), the geometrical parameters of the article (1, 1′, 1″) are determined. Furthermore, with the use of the processing means (33), based on the position of geometric elements of the article (1, 1′, 1″) in the image (P, P′, P″), the geometrical parameters of the multi-segment article (1, 1′, 1″) are measured.
