摘要 圆柱状构件广泛存在于古建筑仿真中,为了提高古建筑深度图像圆柱拟合的精度,针对古建筑仿真3维建模的特点,提出基于高斯图获取圆柱拟合参数初始值,然后利用圆柱距离函数参数化法进行非线性最小二乘拟合的圆柱拟合方法。实验证明,该方法不仅具有较高的精度,而且拟合结果稳定可靠。 Cylinder components existed widely in ancient building emulation. To improve the precision of cylinder fitting, aiming at the trait of ancient building emulation, a robust cylinder fitting method was put forward, which at first got initial cylinder parameter values by Gauss image, then fit cylinder by nonlinear least squares for parametefized distance function. The experimented results demonstrate the stability and high precision of the method.
