This is a data set of 61 blood spatter patterns scanned at high resolution, generated by controlled impact events corresponding to forensic beating situations. The spatter patterns were realized with two test rigs, to vary the geometry and speed of the impact of a solid object on a blood source - a pool of blood. The resulting atomized blood droplets travelled a set distance towards a poster board sheet, creating a blood spatter. Fresh swine blood was used; its hematocrit and temperature were measured. Main parameters of the study were the impact velocity and the distance between blood source and target sheet, and several other parameters were explored in a less systematic way. This new and original data set is suitable for training or research purposes in the forensic discipline of bloodstain pattern analysis.
这是一个包含61个高分辨率扫描的血迹模式的数据集，由与法医殴打情况相对应的受控撞击事件生成。血迹模式通过两个试验装置实现，以改变固体物体对血源（一滩血）撞击的几何形状和速度。产生的雾化血滴朝着一块海报板行进一段设定的距离，从而形成血迹。使用的是新鲜猪血；测量了其血细胞比容和温度。该研究的主要参数是撞击速度以及血源与目标板之间的距离，还以较不系统的方式探究了其他几个参数。这个全新的数据集适用于血迹模式分析法医领域的训练或研究目的。
