Abstract: A system for guiding a surgical or medical procedure includes a depth camera for acquiring images and/or video from a predetermined site of a subject before, during, or after a planned surgical or medical procedure and a high definition projector for projecting surgical markings onto this predetermined surgical site. The system also enables a remote educator or expert to guide the procedure by annotating a three-dimensional digital image of the subject such that this input is then projected onto the actual subject in real time. A trained machine learning guide generator is in electrical communication with the depth camera and the projector. Characteristically, the trained machine learning guide generator implements a trained machine learning model for the predetermined anatomic site. Advantageously, the trained machine learning guide generator is configured to control the projector using the trained machine learning model to bind projection such that surgical markings that guide surgical or medical procedures are stably projected onto the subject despite movement.
