1. An operation image positioning method, executed by a computer system, comprising:
capturing a point-cloud image by a point-cloud camera, wherein the point-cloud image contains a first positioning mark and a second positioning mark, wherein the first positioning mark is fixed on a treated portion and the second positioning mark is fixed on an X-ray imaging machine;
recognizing the first positioning mark within the point-cloud image by the computer system so as to compute a first conversion module between the point-cloud camera and the treated portion;
recognizing the second positioning mark within the point-cloud image by the computer system so as to compute a second conversion module between the point-cloud camera and the X-ray imaging machine;
computing a third conversion module between the treated portion and the X-ray imaging machine, by the computer system, according to the first conversion module and the second conversion module;
capturing a positioning image by an image positioning camera, wherein the positioning image contains the first positioning mark;
recognizing the first positioning mark within the positioning image by the computer system so as to compute a fourth conversion module between the image positioning camera and the treated portion; and
computing a fifth conversion module between the image positioning camera and the X-ray imaging machine, by the computer system, according to the third conversion module and the fourth conversion module.
