摘　　要：为解决铁路旅客运输中用X射线安检仪对旅客行包进行安检时,人工判断行包所属旅客工作难度大、效率低的问题,提出一种结合人脸探测及时间关联的人包信息绑定与输出显示系统。在不改变X射线安检仪和装置结构的基础上,在X射线安检仪入口处设置监控摄像机对旅客放置行包过程进行图像采集,通过算法合理计算旅客放行包与安检机采集行包X射线图像时间差,并用人脸分类器快速筛选出含有对应人脸的图像,与行包X射线图像自动绑定。通过实际软硬件调试和人包绑定实验数据分析证明方法的有效性。This paper intends to solve the diffi culty and ineffi ciency in manually judging the ownership of passenger luggage during the security check of passenger luggage using X-ray security scanner in railway passenger transport.It proposes a biding and display system for passenger and luggage information using a new method that combines face recognition with time correlation.The structure of the traditional X-ray security scanner and its devices is not changed.The monitoring camera is arranged at the entrance of the X-ray security scanner to capture images of the passengers’luggage placing process.The appropriate algorithm is applied to calculate the time difference between the luggage placing by the passengers and the X-ray passenger and luggage image acquisition by the security scanner.The face classifi er is utilized to rapidly screen the corresponding face images and automatically bind such face images to the X-ray luggage images.The eff ectiveness of the proposed method is proved by actual hardware and software debugging and binding test data for passenger and luggage information.
