The three-dimensional measuring of objects in many areas continues to gain in importance. The concept: The Volpi projector illuminates an object with parallel bars of light or a grid of lines, depending on the application. The industrial camera records the resulting pattern to yield a sort of topography. In a fraction of a second a computer then generates the 3D picture of the recorded object. In doing so, the bars of light are encoded in color or with chronological redundancy. In this way it is possible for the system to define each individual bar clearly and reliably. Depending on the encoding, the procedure, which is based only on standard components, can even collect a 3D data set from a single video image. As a result, it is possible to represent moving objects in three dimensions.
Three-dimensional surveying is employed in numerous industrial and non-industrial fields. |
