Embodiment Construction
[0036] The present invention will be described below in conjunction with the accompanying drawings.
[0037]The invention relates to a surgical positioning scale, which is used for the spatial positioning calculation of the surgical path between an X-ray light source and an X-ray imaging device, and includes two opposite surfaces that transmit X-rays, and the two opposite surfaces are fixedly connected through the connection surfaces that transmit X-rays , the distance between the two opposite surfaces is 5cm-15cm, and a group of marks are set on the two opposite surfaces, and each group of marks includes at least four non-existing objects based on the calibration of the linear camera model in the X-ray imaging device and the three-dimensional space point reconstruction principle. Marking points on a straight line, each marking point is an X-ray-opaque component; any opposite surface or connection surface is fixedly connected to a scale handle, and an interface for connecting w...
