Systems, methods, and media for performing shape measurement

A method for performing shape measurement, comprising:

• projecting onto a scene a plurality of illumination patterns using a projector, wherein each of the illumination patterns has a given frequency, each of the illumination patterns is projected onto the scene during a separate period of time, three different illumination patterns are projected with a first given frequency, and only one or two different illumination patterns are projected with a second given frequency;
• detecting an image of the scene during each of the plurality of periods of time using a camera;
• determining the given frequencies of the plurality of illumination patterns using a hardware processor;
• and
• measuring a shape of an object in the scene using the hardware processor.

A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for performing shape measurement, the method comprising:

• projecting onto a scene a plurality of illumination patterns, wherein each of the illumination patterns has a given frequency, each of the illumination patterns is projected onto the scene during a separate period of time, three different illumination patterns are projected with a first given frequency, and only one or two different illumination patterns are projected with a second given frequency;
• detecting an image of the scene during each of the plurality of periods of time;
• determining the given frequencies of the plurality of illumination patterns;
• and
• measuring a shape of an object in the scene.
