摘要： The present disclosure relates to a method, a device and a system for inspecting a moving object based on cosmic rays, pertaining to the field of radiation imaging and safety inspection techniques. The method includes: detecting whether a speed of the inspected moving object is within a preset range; recording a motion trajectory of the moving object with a monitoring device; acquiring information about charged particles in the cosmic rays with a position sensitive detector, the information about charged particles including track information of the charged particles; determining the moving object by matching positions of the motion trajectory and the track information; reconstructing the track of the charged particles according to the information about the charged particles; and recognizing the material inside the moving object based on the track reconstruction.
