基于自然界各类花朵普遍具有的对称特性，提出了一种利用单幅图像的三维花朵建模方法.根据输入的单幅花朵图像，用户通过交互方式描绘花朵每个花瓣的2条边缘曲线，对花朵边缘曲线的顶部顶点和底部顶点进行最小二乘圆锥拟合，利用拟合得到的圆锥计算花朵各花瓣的对称面；根据不同种类花朵所固有的对称特性和各个花瓣的对称面信息，计算花瓣2条边缘曲线上所有采样点的深度，得到其三维构造曲线；利用恢复了深度信息的三维构造曲线作离散化网格处理，构建各个花瓣的三维模型，进而重建整个花朵的三维模型；最后根据输入的单幅图像纹理信息合成花朵的表面纹理，得到了真实感较强的花朵模型.实验结果表明：该建模方法充分利用了花朵的对称特性，用户交互少、建模效率高，能够准确地从单幅花朵图像中恢复其深度信息和整体结构，方便快捷地实现花朵的三维重建.
