X-ray imaging and CNN express parcel contraband detection method

Abstract

The invention discloses an X-ray imaging and CNN express parcel contraband detection method, and relates to the field of optical engineering and artificial intelligence, and the method comprises the following steps: (1) obtaining parcel X-ray image information; (2) dividing a wrapped X-ray image sample; (3) extracting features of the wrapped X-ray image; and (4) constructing a random forest contraband parcel identification model. According to the invention, the CNN-RF is adopted to construct an express parcel contraband detection model, a new convolutional neural network model is provided, more and more effective feature information can be extracted, over-fitting can be avoided, two GPUs are used for training, the training speed is greatly increased, and the method is very suitable for accurate and rapid detection of express parcel contraband goods.

Description

technical field [0001] The invention relates to the fields of optical engineering and artificial intelligence, and mainly relates to a detection method for express parcels containing contraband. Background technique [0002] With the development of the economy in recent years, the express delivery market has become increasingly prosperous. The express delivery industry is a labor-intensive industry with long working hours and complicated processes. Due to the lack of professional knowledge of the express business outlets, contraband may be received, causing unnecessary impact on economic and social development and public safety. [0003] Artificial intelligence (AI) is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. It mainly includes robotics, image processing, natural language processing, expert systems, etc. Convolutional Neural Networks (CNN) is a type ...
