Terrestrial Laser Scanners (TLS) are used frequently in three dimensional documentation studies and present an alternative method for three dimensional modeling without any deformation of scale. The segmentation studies suggest several methods for automation of curve surface determination for digital terrain modeling. Fuzzy segmentation alghorithms have been used for several studies recently. In this study, fuzzy logic approach has been used for the automatic segmentation of the regular curve surfaces which differ in their depths to the instrument. This type of shapes has been usually observed in the dome surfaces for close range architectural documentation. Gauss2mf membership functions algorithm has been tested with original data set. These results were used in photogrammetric 3D modeling process.
