The visualization system can be communicatively coupled to a situational awareness module configured to determine a surgical scenario based on input signals from multiple surgical devices.

A method measures an edge of a workpiece by scanning. The scanning is performed by a scanning tool mounted on a moving head of an edge-facing machine while that moving head is moved along the edge to be measured before, during or after an edge facing tool of the edge-facing machine that faces the edge. The method can be performed by an edge-facing machine that includes at least one edge facing tool and that further includes a scanning tool mounted on a movable head of the machine, which head is movable along an edge of a workpiece.

Provided is a projection system that sets an arbitrary three-dimensional shape as a projection target and properly corrects geometric distortion of a projected image even when a user's viewpoint is not fixed. A projection unit of the projector apparatus projects a test image for first adjustment. A three-dimensional shape measurement unit measures the three-dimensional shape of the projection target. An image capturing apparatus captures the test image for first adjustment projected by the projection unit to obtain a captured image for first adjustment. A projected image adjustment unit (1) performs first adjustment processing for correcting an image such that geometric image distortion viewed from an imaging point, at which the captured image for first adjustment has been captured, is reduced, based on a captured image for first adjustment obtained by the image capturing apparatus, and (2) performs second adjustment processing for correcting the image such that the geometric image distortion is reduced based on a state in which the image adjusted by the first adjustment processing is projected by the projection unit.
