论文摘要
重建溅射模式的起源领域通常是确定受害者受伤的犯罪现场地区的基本步骤。在这一领域，近十年来，意大利polizia di Stato一直使用Antragos，这是一种法医软件，它实现了一种概率方法，以识别一组血液滴的水平轨迹融合的水平投影（融合区域）并估算出来源的高度。在本文中，我们总结了在已发表的Spater模式数据集上执行的一系列测试，其结果证实了Antragos及其算法的有效性。作为一个侧面结果，在统计和流体动态方法中得出了一些有用的建议，以确定原产地的确定。
The reconstruction of the area of origin of spatter patterns is usually a fundamental step to the determination of the area of the crime scene where the victim was wounded. In this field, for almost a decade, the italian Polizia di Stato has employed AnTraGoS, a forensic software which implements a probabilistic approach to identify the area where the horizontal projections of the trajectories of a set of blood drops converge (area of convergence) and to estimate the height of origin. In this paper we summarize a series of tests performed on a published dataset of spatter patterns, whose results confirm the validity of AnTraGoS and of its algorithms. As a side result, some useful suggestions are derived, concerning the determination of the height of origin, within a statistical and fluid dynamic approach.
