Abstract: 다중공간주파수를이용한 3차원물체의깊이측정방법은임의의공간주파수를갖는광패턴을투사기를이용하여 3차원물체에투사하고, 디지털카메라를이용하여물체를촬영한다. 임의의공간주파수를갖는패턴은물체표면에서깊이에따라상이한굴곡과형태를보여주므로, 깊이에따른특정굴곡과형태를기하학적변수를이용하여물체의형상즉, 깊이를측정한다.

Abstract: PURPOSE: A method and an apparatus for measuring the depth of a three dimensional object using multiple spatial frequencies are provided to simply and accurately measure the depth of a discontinuous three dimensional object without executing unwrapping algorithm. CONSTITUTION: An apparatus for measuring the depth of a three dimensional object using multiple spatial frequencies comprises a projector(10), a photographing unit(20), and a measuring unit(30). The projector scans lights, which correspond to a multi spatial frequency pattern including patterns according two or more spatial frequencies, to a three dimensional object. The photographing unit photographs the three dimensional object scanned with the lights and outputs a corresponding digital image signal. The measuring unit calculates the depth of the object based on the digital image signal.
