Abstract: A method of obtaining a measurement of a part using depth data from a plurality of sensors comprises obtaining 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. A plurality of planes is detected in the first depth data and the second depth data. Each plane of the plurality of planes corresponds to a corresponding face on the monument. The method comprises performing a rotational alignment of the plurality of planes. The method further comprises performing a translational alignment of the rotationally aligned plurality of planes. One or more transformations are determined 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. A measurement of the part is determined based upon aligned depth data.
