. Converting paper-based engineering drawings into CAD model files is a tedious process. Therefore, automating the conversion
of such drawings represents tremendous time and labor savings. We present a complete system which interprets such 2D paper-based
engineering drawings, and outputs 3D models that can be displayed as wireframes. The system per...
Converting paper-based engineering drawings into CAD model files is a tedious process, and automating the conversion of such drawings represents tremendous time and labor savings. We present a complete system which interprets such 2D paper-based engineering drawings, constructs solid models, and outputs 3D CAD-like files. While most existing system...
A method is presented for segmenting engineering drawings into views and identifying the corresponding view points. A set of 2.5D view-based coordinate systems is introduced as an intermediate between the 2D drawing-based system and the 3D object-based coordinates, and a formal technique is developed for constructing transformation matrices between...
A computer vision system to automatically analyze and assemble an
image of the pieces of a jigsaw puzzle is presented. The system, called
Automatic Puzzle Solver (APS), derives a new set of features based on
the shape and color characteristics of the puzzle pieces. A combination
of the shape dependent features and color cues is used to match the
pu...

... In addition to quantity surveying, the recognition is also useful for other applications, such as 4D modeling, virtual reality, and graphical retrieval system. We note that there has been extensive research on the recognition and 3D reconstruction of mechanical parts from engineering drawings678910111213. Due to the differences between engineering and architecture drawings, we will conclude these methods are not suitable for our intended problem [1,2]. ...

... In the preprocessing step, a standard three-view (two-view is also allowed) drawing of a mechanical part are input from a neutral DXF file, then views in the drawing are separated and identified as the front, side or top view according to their relative positions in the drawing, and finally each view is transformed from drawing-based coordinate system (as shown inFig. 1 (a)) to objectbased coordinate system [9] as shown inFig. 1(b). ...
... Graphical symbols are generally 2D-graphical shapes, including their composition in the highest level of conceptual information. Overall, it plays a crucial role in a variety of applications such as automatic interpretation and recognition of circuit diagrams (10; 11), engineering drawings and architectural drawings (12)(13)(14)(15), line drawings (16), musical notations (17), maps (18), mathematical expressions (19), and optical characters (20)(21)(22)(23). Graphics is often combined with text, illustration, and color. ...

... The development of computational approaches to the solution of jigsaw puzzles using only shape information began as early as 1964, [1]. Much of the ensuing work, e.g., [2][3][4], has focused on traditional rectangular jigsaw puzzles, and leverages assumptions about piece shape and puzzle arrangement in the solving process. Key assumptions among these are that puzzle pieces are four-sided with "indents" and "outdents" and that there are corner and edge pieces which may be identified and assembled separately from interior pieces. ...
