中文摘要 | 本篇論文針對本實驗室所開發出來之結構光三維掃描器,所建立的三維臉部模型,提出一個快速的佈點演算法。由三維掃描器之變相機結構,可以得到分別對應到每一臺相機之二個三維臉部模型。在所提出之演算法內的合併步驟中,提出了一個有效率的方法,將二個局部的三維臉部模型,合併成為一個完整的三維臉部模型,並以標準的點雲格式輸出。合併後的點雲格式臉部模型,再以所提出之基於二維半調技術的佈點方式,進行佈點。最後,佈點的結果,以雷射內雕機呈現於水晶玻璃之內。由結果可看出,本篇論文所提出的演算法可達到極佳的性能。 |
英文摘要 | This paper presents a stippling algorithm for 3D models scanned by the structured light 3D scanner developed in our laboratory. Two 3D models, one for each side of the face, are obtained from the dual cameras equipped with the scanner. In the merging step of the algorithm, an efficient method is proposed for merging the two facial models to form a complete model of the face with the standard points could format. The merged facial model is stippled by the stippling routine of the algorithm. The stippling routine is based on 2D halftoning techniques. Finally, the stippling result is reappeared in a piece of crystal glass by a laser interior engraver. The result shows that the algorithm achieves an excellent performance. |
