Coaxial rotatable laser positioning and guiding system based on intraoperative perspective image

The utility model relates to a coaxial rotatable laser positioning and guiding system based on an intraoperative perspective image, the axis of a first X-ray receiving imaging device and the axis of a second X-ray receiving imaging device of a G-arm machine intersect to form a virtual original point, and both a lateral perspective view and a normal perspective view comprise preoperative positioning target points; rotating shafts of the first laser transmitter and the second laser transmitter respectively pass through the virtual original point; in the normal perspective view, a first included angle is formed between the normal projection of the preoperative positioning target point and the laser surface initially emitted by the first laser emitter; in the lateral perspective view, a second included angle is formed between the lateral projection of the preoperative positioning target point and the laser surface initially emitted by the second laser emitter; the controller is used for controlling the first driv
