A method for assisting an orthopedic surgery, the method including the steps of: capturing a sequence of images such that a field of view captures images of a plurality of screw extenders, each screw extender holding a pedicle screw, the plurality of screw extenders arranged at a surgical incision of an orthopedic surgery, displaying images of the captured images to provide for a live video feed, detecting the plurality of screw extenders based on the captured sequence of images, first calculating an orientation and position of the detected plurality of screw extenders, second calculating a 3D position of a screw head of each pedicle screw based on the orientation and the position, and projecting and displaying each calculated 3D position of the plurality of screw heads with a graphical element on the display device at a location that corresponds to the location of the screw head projected to a currently displayed image of the live video feed.
