Explore how to recognize and describe 3-D objects through curves
This book presents a practical approach to matching 3-D curves to identify and position object parts, even when views overlap or objects are partially hidden. It combines theory with step-by-step methods that work in real time.
The work focuses on turning complex 3-D shapes into sequences of local, invariant curve signatures. It explains how to use these footprints to filter candidates, then apply robust 3-D subcurve matching to confirm the best fit. Realistic applications include reassembling broken objects and building full object descriptions from partial views, using hands-on experiments with 3-D curve data.
What you’ll experience
- How to represent curves with local, rotationally and translationally invariant signatures.
- The idea behind geometric hashing to identify long matching subcurves.
- How the Schwartz–Sharir algorithm is used to compute alignments in 3-D space.
- Practical workflows for 3-D curve reconstruction from multiple viewpoints.
Ideal for readers who want a hands-on introduction to 3-D curve matching, object recognition, and curve-based model construction. It’s especially relevant for researchers and practitioners in robotics, computer vision, and CAD.
