| Sumario: | This document proposes a set of processes necessary to convert a 2D topographic map into 3D information. First of all, the image information has to be processed in order to be translated into a digital format. This processing is formed by some sub-steps: image processing, acquisition of the image information (contour lines), contour line processing and number recognition (elevation numbers). The output of these processes could be displayed using either 2D or 3D data. The first can be represented through the same contour map but showing the elevation values by means of a colour range. Otherwise, the relief will be illustrated using a 3D mesh, which can be directly displayed or employing marker-based augmented reality. Some of the main topics included in this document are: image processing, optical character recognition and augmented reality. |
