6. CONCLUSION AND FUTURE WORK 
This test project demonstrates the feasibility of high precision digital object reconstruction using free-formed curves. 
The accuracy of the reconstructed lines corresponds to the uncertainty of definition of these lines on the car. 
Emphasis was laid.on working with realistic conditions (natural illumination, real-world object, non-targetted lines). In 
the future further tests with lower image resolution are planned. Although a certain level of automation has already 
been achieved, some tiresome user interaction is still required. In order to reduce interactive work we think of using 
hierarchical methods for extracting longer edges. Also we will concentrate on finding optimum matching algorithms for 
edge features.
