Sažetak
The paper shows usage of modern systems for optical measuring in reverse engineering methods. When due to large dimensions of the measuring object and its complexity it is not practical or possible to use conventional measuring methods, the surface of these objects or points on them can be digitized, and based on that, 3D CAD models can be created. The obtained models represent a good basis for further construction development, analysis and simulation. For this purpose two measuring systems are used: TRITOP and ATOS. High precision measuring system TRITOP determines the 3D coordinates of markers and other visible elements on the surface of the measured object, what allows quick and efficient on site measurement. This system was used in the first example for determining the position of the centerline end-points at the body structure of a city bus. Obtained computer wireframe model was the basis for creation of 3D CAD and FEM models. The second system, ATOS, determines the three-dimensional coordinates of points with two digital cameras which record the object’s surface, based on the principle of triangulation, thus generating a polygon mesh which describes the form of the digitized object. In the second example this system was used to digitize door frame and door. The obtained 3D CAD models were the basis for synthesis and analysis of a new mechanism of side door opening of a personal vehicle adapted for a disabled person.
