A method, a device and a security system for image data processing based on VR or AR are disclosed. In one aspect, an example image data processing method includes reconstructing, based on three-dimensional (3D) scanned data of a containing apparatus in which objects are contained, a 3D image of the containing apparatus and the objects contained in the containing apparatus. The reconstructed 3D image is stereoscopically displayed. Manipulation information is determined for at least one of the objects in the containing apparatus based on positioning information and action information of a user. At least a 3D image of the at least one object is reconstructed based on the determined manipulation information. The at least one reconstructed object is presented on the displayed 3D image.

Image data processing method, device and security inspection system based on VR or AR

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.
