For years, NUB3D has developed several optical measuring heads for different fields and industrial applications. They are based on continuous research and developped in our laboratories for optical scanning technology. NUB3D was the first company to develop a technology that allows scanning of objects without contact with the object, MML. The MML avoids having to use adhesive marks or targets in order to make the registration of multiple views the result of digitization. The effectiveness of such systems is shown by the increased productivity and quality in design cycles and production of product. Therefore, it makes them indispensable tools for enhancing competitiveness of enterprises. The scanning process uses a combination of optical technology, topometry 3d and digital image processing to extract coordinates of points from the surface of an object. As a single element in the whole process is the light, giving three-dimensional point cloud of great density and high accuracy within seconds. | |  | | The process of acquiring 3D information is performed using the technique known as structured white light triangulation.
On the surface of the part to be measured is projected a series of white vertical stripes and black light. The three-dimensional information is obtained by analyzing the deformation of the projected lines suffer when reflected on the surface of the object. A camera built into the measuring head captures a series of images which show the piece and the deformation of the beam lines. This process of projection and image acquisition takes a few seconds. From these images we calculate a 3D point cloud (coordinates x, y, z) of the object surface. |
