Multi-view exposure X-ray image positioning method and system

A multi-view exposure X-ray image positioning system, wherein the system comprises:

• a data acquisition module configured for acquiring volumetric data information about a target object;
• a data collection module configured for, according to the volumetric data information, sequentially shooting X-ray images corresponding to multiple view angles according to a time sequence based on a pre-set time period;
• a first data receiving module configured for, in the case where the target object is in a static state, receiving the X-ray images of all view angles at a moment corresponding to the static state to generate a first image sequence, and obtaining a first rotation displacement matrix according to a first optimization algorithm;
• a second data receiving module configured for, in the case where the target object is in a non-static state, receiving the X-ray images from a first view angle to a last view angle in the pre-set time period as a second image sequence according to the time sequence, and performing optimization processing on the second image sequence to obtain a plurality of second rotation displacement matrices;
• and
• a positioning module configured for achieving dynamic positioning of the X-ray image of the target object according to the first rotation displacement matrix, and the plurality of second rotation matrices corresponding to the image sequences in the non-static state.
