Augmented reality measurement and schematic system including tool having relatively movable fiducial markers

A computer-readable medium having instructions stored in a memory that, when executed by one or more processors associated with a head-mounted display device, cause the one or more processors to:

• cause one or more sensors to identify:
• a first geometric position of a first point in space indicated by a first plurality of fiducial markers of a first tool member of a measurement tool;
• one or more second geometric positions of one or more respective second points in space associated with placement of the first tool member and a second tool member of the measurement tool relative to a surface of a real-world structure, wherein the second tool member includes a second plurality of fiducial markers each indicating a respective second point in space relative to the second tool member;
• and
• wherein the first geometric position and the one or more second geometric positions are in a coordinate system relative to the head-mounted display device;
• generate a final dimension of a part of the real-world structure based on at least the one or more second geometric positions according to relative geometric relationship with respect to the first point;
• and
• cause a near-eye display configured to display a virtual schematic diagram of the real-world structure having the final dimension.

A method of measuring a dimension of a real-world structure and generating a schematic using a head-mounted display device, comprising:

• identifying a first geometric position of a first point in space indicated by a first plurality of fiducial markers of a first tool member of a measurement tool;
• identifying one or more second geometric positions of one or more respective second points in space associated with placement of the first tool member and a second tool member of the measurement tool relative to a surface of a real-world structure, wherein the second tool member includes a second plurality of fiducial markers each indicating a respective second point in space relative to the second tool member and wherein the first geometric position and the one or more second geometric positions are in a coordinate system relative to the head-mounted display device;
• generating a final dimension of a part of the real-world structure based on at least the one or more second geometric positions according to relative geometric relationship with respect to the first point;
• and
• displaying a virtual schematic diagram of the real-world structure having the final dimension.
