(57) A method for automatically detecting and counting bodies passing through a gap (A)
includes the steps of monitoring the gap (A) with means for generating image signals
(3; 4, 9) to obtain a succession of images (4a, 4b; L0, L1, ..., LN) of each body (B) passing through the gap (A), of processing these images (4a, 4b;
L0, L1, ..., LN) to obtain an altimetric map for each body (B) passing through the gap (A) for each
moment considered, of comparing at least one altimetric map obtained with at least
one model of altimetric map stored in a processing unit (5), and of activating a counting
procedure depending on the result of the comparison.
