A device may provide, to a camera and a projector of a portable projection mapping device, first instructions for calibrating the camera and the projector, and may receive, based on the first instructions, calibration parameters for the camera and the projector. The device may calculate a stereo calibration between the camera and the projector based on the calibration parameters, and may provide, to the camera, second instructions for recognizing a reference instrument associated with the portable projection mapping device. The device may receive, based on the second instructions, binocular images, and may determine additional parameters based on the binocular images. The device may determine recognition parameters for recognizing the reference instrument, based on the binocular images and the additional parameters. The device may process the recognition parameters and the stereo calibration, with an optical tracking model, to generate and provide overlay visualization data to the portable projection mapping device.

Provided is a method for forming an implant with an autonomous manufacturing device. The method includes accessing a first computer-readable reconstruction of a being's anatomy; accessing a second computer-readable reconstruction of an implant; accessing a third computer-readable reconstruction comprising the first computer-readable reconstruction superimposed with the second computer readable reconstruction; generating at least one computer-readable trace from a point cloud; and forming an implant with an autonomous manufacturing device, wherein the autonomous manufacturing device forms the implant into a shape defined by at least one dimension of the computer-readable trace.
