多视角X射线内部结构不均匀物品密度探测新方法

多视角X射线安检设备密度探测方面由于当前的原理和方法有局限性,不能对被检查的内部结构不均匀物品进行密度检测,对多视角X射线安检设备自动探测效率有很大影响。提出了一种全新的基于变形图像三维空间校正(CAD表的建立)和被检测物品切片面积快速估计的密度探测方法。实验结果表明,该方法对内部结构不均匀物品密度探测有很强的区分性和稳定性,具有实践应用意义。

The New Method of Multi-view X-ray Density Detecting for Internal Structural Inhomogeneous Items

Multi-view X-ray security equipment , as the current principles and methods have limitations, can not be used to detect internal structural inhomogeneous items in the aspect of density detection, so it has great influence on multi-view X-ray security equipment detection efficiency. This paper presents a new density detecting method based on three-dimensional space correction of distorted images (CAD establish) and quick estimating the slice area of items detected. Experimental results show that this method in density detecting has a strong distinction and stability, and it has practical application significance.
