Computer numerically controlled fabrication using projected information

A system, comprising:

• at least one data processor;
• non-transitory computer-readable medium;
• and
• program instructions stored on the non-transitory computer-readable medium that are executable by the at least one processor such that a computing device is configured to:
• project, by one or more light sources, a known number and arrangement of light rays as a structured light pattern on a surface within a computer numerically controlled machine configured to deliver electromagnetic energy;
• receive, from one or more sensors, image data representing the projected structured light pattern that includes one or more distortions caused by one or more characteristics of the surface at one or more locations on the surface;
• perform one or more calibrations to the image data to remove, from the image of the projected structured light pattern, one or more optical distortions associated with the one or more sensors, the one or more optical distortions including an optical distortion associated with the surface being disposed at a short distance from the one or more sensors;
• generate, based on the calibrated image data, an image of the projected structured light pattern that includes the one or more distortions:
• based on the image of the projected structured light pattern that includes the one or more distortions, identify the one or more characteristics of the surface at the one or more locations on the surface, wherein the one or more locations on the surface corresponds to the known number and arrangement of light rays;
• and
• generate a surface map indicating the one or more characteristics of the surface at the one or more locations on the surface.

A non-transitory computer-readable medium, wherein the non-transitory computer-readable medium is provisioned with program instructions that, when executed by at least one processor, cause a computing device to:

• project, by one or more light sources, a known number and arrangement of light rays as a structured light pattern on a surface within a computer numerically controlled machine having a head configured to deliver electromagnetic energy;
• receive, from one or more sensors, image data representing the projected structured light pattern that includes one or more distortions caused by one or more characteristics of the surface at one or more locations on the surface;
• perform one or more calibrations to the image data to remove, from the image of the projected structured light pattern, one or more optical distortions associated with the one or more sensors, the one or more optical distortions including an optical distortion associated with the surface being disposed at a short distance from the one or more sensors;
• generate, based on the calibrated image data, an image of the projected structured light pattern that includes the one or more distortions;
• based on the image of the projected structured light pattern that includes the one or more distortions, identify the one or more characteristics of the surface at the one or more locations on the surface, wherein the one or more locations on the surface corresponds to the known number and arrangement of light rays;
• and
• generate a surface map indicating the one or more characteristics of the surface at the one or more locations on the surface.
