Abstract

The invention discloses a radiation image generation method and system. The method comprises the following steps: acquiring a vehicle radiation image obtained after a vehicle is irradiated by radiation rays; obtaining a forbidden article radiation image group obtained after radiation rays irradiate the forbidden article; and carrying out pixel-level fusion on different positions of the prohibited article radiation image group and the vehicle radiation image to obtain a plurality of vehicle radiation images containing the prohibited articles. According to the method, pixel-level fusion is carried out on the radiation images of the forbidden objects collected independently at different positions of the vehicle radiation images, so that rich vehicle radiation images containing the forbidden objects can be obtained, all the obtained images serve as training samples to train the model, and the accuracy of the model can be greatly improved. Meanwhile, due to the fact that the radiation images of the forbidden objects and the radiation images of the vehicles are independently collected, the collection process is simple and convenient, and a large amount of manpower, material resources and time are not consumed.

Description

technical field [0001] The invention relates to a radiation image generation method and system, belonging to the technical field of image generation. Background technique [0002] The current general vehicle inspection technical solution is to place a radiation source on the side of the inspected vehicle for imaging to obtain a radiation image of the vehicle. It is based on the principle that radiation will be absorbed when it passes through matter, and the absorbed portion is related to the material properties (absorption coefficient μ), thickness (mass thickness) and the energy of incident photons on the path. When an object is placed in the "irradiation field" of the radiation, the weakening of the radiation intensity after passing through the object depends on the material and thickness on the path. Record the distribution of the radiation intensity after passing through the object. Based on this, the distribution of substances inside the object can be judged. [0003]...
