Limited article automatic identification device and method

Abstract

The invention relates to a limited article automatic identification device and method. The method comprises the following steps of: a, high-energy data, low-energy data and a pseudo-color image of a parcel to be identified is acquired by an X-ray machine; b, the high-energy data and the low-energy data serve as data of a first channel and data of a second channel respectively, data of a third channel is synthesized according to a calculation formula, and a self-synthesized security check image of the parcel to be identified is obtained; c, a deep learning model is adopted to extract data features of the self-synthesized security check image, whether a restriction exists in the self-synthesized security check image or not is recognized through a deep learning classifier and a regression algorithm, and a recognition result is output; and d, template registration is performed on the self-synthesized security check image and the pseudo-color image, a restriction identification result is marked on the pseudo-color image according to a registration result, and the restriction identification result is displayed. The identification accuracy is relatively higher, the labor cost of security check is reduced, and the efficiency of security check is improved.

Description

technical field [0001] The application belongs to the technical field of security inspection object identification, and in particular relates to an automatic identification device and method for restricted items. Background technique [0002] Nowadays, railway stations, subways, airports and other places will check the luggage carried by passengers, and passengers are not allowed to carry restricted items on transportation, and necessary safety risk control is carried out. X-ray baggage security inspection equipment is widely used in the fields of maintaining aviation and subway traffic safety, and provides important technical support for security inspectors to inspect compact, messy and highly variable baggage contents within a limited time frame. X-ray baggage security inspection equipment displays organic, inorganic, and mixtures as orange, blue, and green false-color images by irradiating the items in the luggage and through a series of image processing methods such as i...

Problems solved by technology

Its disadvantages are: relatively poor mobility and relatively poor accuracy

During the peak travel period, it is inevitable that there will be machine warnings, but the package that has the warning cannot be located in time. It is difficult to open the package and check for a long time, which greatly delays the security check speed or even misses the check, causing safety hazards
