摘    要:针对手绘复杂雕刻图案的特点,利用分段三次Bezier曲线实现手绘复杂雕刻图案的矢量化。提出一种自适应区分线条图案和区域块图案及提取区域块图案边界的解决方案。依据检测的角点信息将得到的轮廓边界分解成若干条独立的线段。曲线拟合时,为提高拟合精度,根据线段数据点到曲线的偏移量对线段进一步细分,提出一种实现分段曲线光滑连接的新方法。实验结果表明,该方法对手绘复杂雕刻图案的矢量化具有算法复杂度低、矢量化效果较好的优势,有广泛的实用性。

关 键 词:三次Bezier曲线  角点  曲线拟合  矢量化

Abstract:In view of the characteristic of the complex carving pattern of handcraft drawing, this paper realizes the vectorization of complex carving patterns of handcraft drawing using piecewise cubic Bezier curves. It presents a solution that can adaptively distinguish line patterns and region patterns and extract the boundaries of the region patterns. These boundaries are divided into some independent line segments according to selected corner points. In the curve fitting process, these line segments are further divided according to the offset from the data points of the segment to the curve for enhancing the fitting precision. And a new way of smooth connection of segmented curves is presented. Experimental results indicate that this method has the advantages of lower algorithm complexity and better vectorization effect for vectorization of the complex carving patterns of handcraft drawing, and it has broad practicability.
Keywords:cubic Bezier curves  corner point  curve fitting  vectorization
