Abstract: This paper intends to solve the difficulty and inefficiency 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 classifier is utilized to rapidly screen the corresponding face images and automatically bind such face images to the X-ray luggage images. The effectiveness of the proposed method is proved by actual hardware and software debugging and binding test data for passenger and luggage information.
