Measuring a part using depth data

A computing system, comprising one or more processors configured to:

• obtain first depth data of a monument and a part from a first sensor and second depth data of the monument and the part from a second sensor;
• detect a plurality of planes in the first depth data and the second depth data, wherein each plane of the plurality of planes corresponds to a corresponding face on the monument;
• perform a rotational alignment of the first depth data and the second depth data based upon the plurality of planes;
• perform a translational alignment of the rotationally aligned first depth data and the rotationally aligned second depth data based upon the plurality of planes;
• determine one or more transformations that align the first depth data and the second depth data to a common coordinate system based upon the rotational alignment and the translational alignment;
• use the one or more transformations to align the first depth data and the second depth data, and thereby form aligned depth data;
• determine a measurement of the part based upon the aligned depth data;
• and
• output the measurement of the part.

A system, comprising:

• a plurality of depth sensors arranged in a constellation at least partially surrounding a part and a monument;
• one or more processors;
• and
• a memory storing instructions executable by the one or more processors to,
• obtain depth data of the monument and the part from the plurality of depth sensors;
• detect a plurality of planes in the depth data, wherein each plane of the plurality of planes corresponds to a corresponding face on the monument;
• perform a rotational alignment of the depth data based upon the plurality of planes;
• perform a translational alignment of the rotationally aligned depth data based upon the plurality of planes;
• determine one or more transformations that align the depth data to a common coordinate system based upon the rotational alignment and the translational alignment;
• use the one or more transformations to align the depth data and thereby form aligned depth data;
• determine a measurement of the part based upon the aligned depth data;
• and
• output the measurement of the part.
