摘要
X射线探测包裹中物体互相遮挡,探测得到的是重叠物体的混合灰度值,无法得到单一物体的图像,这给图像处理工作带来很大麻烦;通过对现有的重叠物质识别算法进行分析,提出了采用边缘检测算法去除遮挡效应的数字图像处理算法,建立了3-D边缘模型和数字化模型,并提出3-D图像阈值化分割的方法;该方法已应用到沈阳地泰检测设备有限公司的DEX9080B型X射线安检机,现场应用的结果表明该方法切实可行。
Objects overlapping problem is ubiquitous in luggage. The gained value of gray image is the result of several objects＇ integrated action, can＇t gain single object＇s image. It will bring prodigious trouble to image transformation. This paper analyzes existing arithmetic and put forward using edge detection operator to wipe off the influence of overlapped objects, establish 3-D edge model and digital model, and put forward the method to divide image. This method has been used in DEX9080B x-ray security inspection equipment of DT inspection equipment limited company. The results of application show that the algorithm is feasible.
