Mobile Three-Dimensional (3d) Imaging Machine Based on X-Ray, and 3d Imaging Data Acquisition Method

A mobile three-dimensional (3D) imaging machine based on an X-ray, comprising:

• a machine body, and a limiting mechanism, an exposure imaging mechanism and a position parameter extraction mechanism which are mounted on the machine body, wherein
• the limiting mechanism is configured to control a relative position between the exposure imaging mechanism and an object to be detected, so that the exposure imaging mechanism is able to reach different relative positions between the exposure imaging mechanism and the object to be detected in sequence;
• the exposure imaging mechanism is configured to respectively collect multiple projection data of the X-ray on the object to be detected at a plurality of relative positions;
• the position parameter extraction mechanism is configured to extract relative positions between the object to be detected and the exposure imaging mechanism corresponding to each of the multiple projection data, and/or relative position data between an X-ray source and a detector in the exposure imaging mechanism corresponding to each of the multiple projection data.
