Abstract:
1. An optical three-dimensional structure measuring device that directs measurement light in a depth direction of a lamination of a measurement target with a layer structure and that two-dimensionally scans an optical axis of the measurement light to acquire optical three-dimensional structure information of the measurement target, the optical three-dimensional structure measuring device comprising: an optical three-dimensional structure information storing device for storing the optical three-dimensional structure information; a specific layer extracting device for comparing information values of the optical three-dimensional structure information stored in the optical three-dimensional structure information storing device with a predetermined threshold and extracting, as a specific layer area of the measurement target, an area equal to or greater than a predetermined range where the information values of the optical three-dimensional structure information equal to or greater than the predetermined threshold continue; a missing area extracting device for extracting, as missing areas, areas where the information values of the optical three-dimensional structure information are smaller than the predetermined threshold in the specific layer area; a missing area range calculating device for calculating sizes of ranges of the missing areas; and a region-of-interest classifying device for comparing the sizes of the ranges of the missing areas with a plurality of predetermined range determination reference values, and classifying the missing areas into a plurality of types of regions of interest of classes corresponding to the sizes of the ranges of the missing areas, wherein the region-of-interest classifying device compares the sizes of the ranges of the missing areas with a first range determination reference value and a second range determination reference value which are among the predetermined range determination reference values, and the optical three-dimensional structure measuring device further comprising:
