摘　　要：文章研究的感兴趣区域是指安检包裹中所藏匿的炸药所在区域。首先,根据炸药的原子序数特征,确定包裹中感兴趣区域;其次,获取感兴趣区域的坐标位置信息,在材料图像中扫描出感兴趣内高原子序数物体;最后,确定遮挡剔除算法,在双能量图像中逐点将高原子序数物体遮挡剔除。为感兴趣物体图像分割好准备,服务于多视角截面积重建。In this study, the area of interest is the region where explosives hiding in the security wrap. Firstly, according to the atomic number characteristic of explosives, the region of interest is determined; secondly, obtain the coordinates of the location information of region we are interested and scanning the location information of high atomtic material; and finally, determining occlusion culling algorithms, Excluding the Shelter of high atomtic material point to point. It is ready to object segmentation,servicing the cross-sectional area reconstruction in a multi-angle system.
