A three-dimensional real-time positioning method for orthopedic surgery, including: fixing at least one three-dimensional marking device on the surgical site; setting up an optical positioning system; activating a six-degree-of-freedom calculation module; confirming that both the main and auxiliary camera devices can recognize a multi-faceted cube; Whether the cube is covered, causing the main camera to be unable to shoot; when the multi-faceted cube is not covered, use the main camera to shoot the multi-faceted cube; when the multi-faceted cube is covered, switch to the secondary camera to shoot the multi-faceted cube; Determine whether the main mark is hidden, causing the main or auxiliary camera to be unable to shoot; when the main mark is not obscured, the main mark provides spatial coordinate information; and when the main mark is obscured, the three auxiliary marks are used to calculate The spatial coordinate information of the main marker. |
