Study On Reconstruct 3D Model From Isometric Drawing

The aim of this study is to look for a method to reconstruct 3D model from isometric drawing, but the isometric drawing with removing hidden elements lost not only the depth information but also some topology information. It's a key step to reason the hidden elements to recovery the 3D information. This paper presents an algorithm to reason the hidden elements based on connected edges. Reason the hidden information is to reason through analyze these vertexes that have hidden edges, reason the direction and the length of connected edges and the edges that go through connected vertexes. After reasoning, we get some possible vertexes. Validating them with superposition and the edge circuits, we get the correct hidden element's coordinates and those circuits information. Next step is to reason the depth information. It's to seek the lost depth information based on the vertex's coordinates and those circuits information of the edges. After two phases, the topology and depth information were recovery from isometric drawing. A prototype system was developed to validate this method, and proves it is available to reason the hidden element of the solid surround by planes.
