| Popis: | 104 With the continuous progress of digital communication technology, making object digitized and use three dimensional printers to reproduce could be achieved by reverse engineering technology. These process utilize digital three dimension model to achieve. However, whether using the Shape-From-Silhouettes (SFS) method with single 2D calibration pattern or Stereoscopic to reconstruct a three-dimension model, there are size limits and difficulty for reconstruction items. The purpose of the study is developing a camera calibration process with multiple 2D calibration patterns and a three dimension model with large-scale could be reconstructed by SFS method. In this study, five different calibration pattern and the corresponding decoding process were designed based on the two-dimension camera calibration, so the placement of patterns around objects could be identified. With the homography estimation method, the solid geometry of calibration patterns was obtained. All patterns of all images were integrated into a global coordinate system. Then both of external and internal parameters in each image were determined. The process mentioned above was integrated a human-machine interface program based on C# programing language. User can obtain the modeling information only by inputting the relevant information. Finally, this study chose three small-scale objects and four large-scale objects to demonstrate the reconstruction of three-dimension model for verifying the feasibility of the proposed method in this study. |
