    • Abstract
  • The basic principle of micro-focus X-ray imaging was analyzed. An improved Hough transform method was applied to automatically detect circle parameters of the capsule X-ray digital image, and precise multi-layer capsule geometric parameters were obtained by combining the least squares circle fitting algorithm. The whole image analysis procedure of batch processing was also introduced and a complete capsule X-ray image batch computing software was developed. The wall thickness distribution of the capsule batch calculation was discussed based on the above work. Some examples of the wall thickness distribution of a multi-layer capsule and the whole surface distribution of a monolayer capsule were calculated. This work will contribute to the rapid automatic capsule geometry measurement, and provide more detailed capsule geometry parameters to meet the growing requirements of target fabrication tasks.
