摘　　要：介绍了60Co集装箱检测单源-双视角成像技术的基本原理与特点、系统构成与性能指标以及推广应用。双视角集装箱检测技术通过增加1组探测器阵列,获得两个不同视角的集装箱辐射透射图像,实现对集装箱的双视图对比检测并可生成集装箱的虚拟3D图像,从而实现立体检测,有效改善扫描图像中前后重叠物体和杆状物体的图像分辨效果,显著提高夹藏枪支武器的检出效率。双视角集装箱辐射成像检测技术是常规的单投影集装箱检测技术的重要发展,已在中国海关多个口岸装备运行,并取得巨大的经济社会效益。The research introduced the basic principles and characteristics ,system struc‐ture , performance index and application of dual‐perspective radiography technology using one radioactive source .The technology can obtain two different perspective trans‐mission radiography images of container solely by adding a set of detector array ,so as to realize the three‐dimensional inspection ,effectively improve the image inspection resolu‐tion of overlapping objects and rod‐shaped object ,and significantly improve the detec‐tion efficiency of concealed weapons .The dual‐perspective container radiography inspec‐tion technology is an important development of the conventional single‐projection con‐tainer inspection technology ,and has been widely equipped in China customs ports .It has achieved great economic and social benefit .
