摘　　要：双视角钴-60集装箱检查系统中虽可以对被检大型客体实现虚拟3D显示,但是在人工掏箱检查时,3D检测的定位精度较低。利用双视角图像中可疑物体图像的相对位置差,计算出可疑物体在集装箱内的相对精确位置,大大提高了可疑物体的定位精度和掏箱检查的效率,该方法已应用到中国海关多套双视角钴-60集装箱检查系统中。From the large object images obtained by dual perspectives cobalt-60 container inspection can to be realization of virtual 3D display,but in the artificial dig container inspection,the locating accuracy is lower by3 D inspection. The relative position of the double perspective image of suspicious objects image difference,can be used to calculate the exact relative position of suspicious object in the container,greatly improve the positioning accuracy and the efficiency of digging container to check suspicious object. The method has been applied to China customs multiple sets of double perspective of cobalt-60 container inspection system.
