For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

The present disclosure provides a coordinate calibration device and method based on a distributed ray source imaging system. The coordinate calibration device comprises a ray source and a detector. The ray source is configured to emit X-rays. The detector comprises a detection part and a marking part. The detection part is configured to be disposed within a target area; the detection part and the ray source are respectively arranged on two sides of an object to be measured; and the detection part is configured to receive the X-rays. The marking part is located between the detection part and the ray source; and the relative position of the marking part and the detection part is fixed, wherein at least two marking points are spaced apart on the marking part, the at least two marking points are configured to perform coordinate calibration on X-ray imaging, and the coordinate calibration and the X-ray imaging are performed using the same data. The known parameters on the marking part are used to correct the relative coordinates between the ray source and the detector, and the calculation of the relative coordinates between the ray source and the detector is assisted by relying on the mechanical positioning of the system, thereby reducing the calculation amount of coordinate estimation, improving the relative position accuracy or realizing real-time position calibration, and avoiding secondary capturing, and thus realizing convenient three-dimensional imaging.
