Structure-oriented contour representation and matching for engineering shapes
Conventional shape matching for engineering models primarily considers rigid shape similarity. They do not seek global shape similarity while considering large local deformations. However, engineering models created by some parametric-based design can involve large parametric changes. As a result, they do not share similarity in their global shape. Hence our goal is to develop shape representations for global matching of part models that can have large dissimilarity through stretching and/or bending. This paper presents a strategy of an integrated shape matching for contours of engineering drawings inspired by the divide and conquer paradigm. The original shape is decoupled into two levels of shape representations namely, higher level structure and lower level geometry. The higher level structure matching is then achieved driven by optimal integrated solutions from matching of lower level local geometry. Feature points are first extracted using curve evolution to attain the two levels...
