发明名称 Method for the creation of tridimensional numerical models
摘要 A method for the creation of numerical models of surfaces by acquisition of points from a tridimensional actual model, comprises the steps of identifying a first group of points (X) on at least one boundary (12a, 13a, 14a) defined on the surface (11) of the actual model (10), acquiring the values of the spatial coordinates of the first group of points (X) by means of an acquisition system, and generating a numerical representation of a theoretical surface whose boundary is defined by these points (X). A subsequent step of the method comprises the operation of the acquisition system in order to acquire the coordinates of a second group of points of the actual model, directing it towards the estimated position of nodal points belonging to the theoretical surface. In a last step of the method, a numerical or mathematical representation of the surface of the actual model is generated which satisfies the condition of passing through at least the points of the second group. The method also preferably comprises a step of optimization of the path of the acquisition system, which can comprise contact or non-contact type probes, or even a processing module to identify data of actual points in a preliminarily defined point cloud.
