More Information
Summary:The invention provides a dental arch line generation method based on dental arch region skeleton branch deletion. The dental arch line generation method comprises the steps of extracting a dental arch region skeleton, generating a foreground point dictionary, finding out end points and bifurcation points, deleting skeleton branches according to conditions, and performing equal-arc-length sampling to generate a dental arch line. According to the characteristics of the skeleton branches in the dental arch area, the complex and changeable skeleton branches are automatically processed, the branches are quickly searched and deleted, and the dental arch line is generated by adopting an equal-arc-length sampling method; according to the dental arch line generation method, manual intervention is not needed, the skeleton branch processing speed is high, and the accuracy of the generated dental arch line is high. 本发明提出一种基于牙弓区域骨架分支删除的牙弓线生成方法，包括提取牙弓区域骨架、生成前景点字典、找出端点和分叉点、按条件删除骨架分支、等弧长采样生成牙弓线；本发明根据牙弓区域骨架分支的特征，自动化处理复杂多变的骨架分
