Comparative Studies on the Extraction of Lineaments and Its Variability Based on an Improved Line Segment Tracking Method—Taking the Gaosong Ore Field in the Gejiu Gejiu Tin Ore Deposit as an Example

Remote sensing technology is widely used in the application of extraction lineaments geological research. However, most current traditional lineament methods are based on edge detection using a digital filter to extract mitochondrial features image. These previously algorithms generally unable shadow area mountain and parallel direction solar incident angle. In this paper, we have improved STA algorithm (Line Segment Tracking method). The line segmentation connection were firstly proposed, then 32 search directions set with one pixel as center find best continuity lineament. A threshold was determine whether it element. Finally, elements connected into for further interpretation. data from three different collected Gaosong ore field Gejiu mining area, namely at first place Canny algorithm, segment tracking method, finally measurement. coefficients three-type variations compared by calculating lineaments’ strength their density attributes. It shows that variability extracted method closer measured variability. results show data. has higher precision than algorithm. More realistic comprehensive can be attained which helpful study geology helps construct more accurate structure model serve needs mine production.
