针对各种传统可视外壳生成算法中数据冗余、精确度低、健壮性不足等问题,提出了一种新的可视外壳生成算法,即采用加权线段求交、线段集合中心线性过滤、多边形边界检测等方法重建物体模型.与传统方法相比,本算法能够更稳定地计算线段交集,表面边界提取更加准确,重建结果精确逼近真实物体.实验表明,通过该算法计算的物体可视外壳能够更好地逼近真实模型,精度高.

The traditional volumetric visual hull generating methods were not applicable to huge-volume objects due to redundant calculations.The methods based on segments intersections were sensitive to input perturbations and were hence lack of robustness.This paper represented a new algorithm for reconstructing an object's visual hull from its silhouette.Compared with traditional methods,the approach employs the maximum overlap line segments intersection to calculate line segment intersection stably.In addition,the extraction of the border surface is more accurate.The experiments show that the approach is more accurate and the result of reconstruction approximates the real objects better.
