Quality control of products is everyday more and more demanding. Machine vision is becoming one of the most efficient technologies for the reliable and fast control of different types of products. The more classical techniques in machine vision 2D are valuables in lots of applications, but insufficient when it is necessary a three-dimensional data of the object to study. Classical linear 3D laser detection scanners are not optimized for revolution elements, since the features extraction algorithm needs to be different in each inspection zone and there are shadow zones where the inspection is not possible. In this paper, a novel 3D laser based rotating scanner is described (patent pending request n ES-P200600068). This approach enables inspecting revolution elements avoiding the problems mentioned before. This rotating scanner implementation in a 3D steel tube quality control application is also described
