ABSTRACT:
An improved system of perspective dimensional measurement uses complementary reference surfaces on a camera and on a camera translating unit to provide a repeatable relative orientation between the perspective displacement and the camera's measurement coordinate system while still allowing a rotational and an optional translational degree of freedom for alignment of the camera with an object of interest. In one set of embodiments the rotational axis is accurately aligned with the translation axis. In a second set of embodiments, the geometry of the system is determined in an expanded alignment calibration procedure, the rotation of the camera about the rotational axis is measured, and these additional data are incorporated into the perspective measurement procedure.
