Abstract: A method to detect and to determine geometrical, dimensional and positional features of products (P) transported by a continuous conveyor (2), particularly of raw, roughly shaped, roughed or half-finished steel products, moving forwards with a transport speed lower or equal to a maximum transport speed (V), comprising the steps consisting of: acquiring (100), through at least an image acquisition device (3) placed crosswise to the forwarding direction (F) of a continuous conveyor and at a distance from it, at least a first series of successive images showing a same area across which runs the continuous conveyor (2), on which rests at least a product (P); identifying (101) in the first image series an initial image including the head end of the product (P) considered in respect to the forwarding direction (F); acquiring (102), through the image acquisition device (3), at least a second series of successive images showing the product moving forward along the forwarding direction (F), with an acquisition frequen
