| Abstract: | According to the image interpretation and investigation results of the Great Wall,the following key technologies were used to capture the slope length of the Ming Great Wall in the paper,firstly,the measurement rules for the all kinds of the Section Great Wall were defined;secondly,the beginning and ending position points of each measuring section of the Great Wall were accurately determined;thirdly,the three-dimensional coordinates of each inflex point on the surface center line of the MGW under the stereo pairs with uniform standards and technical processes were accurately measured;finally,under the unified length calculation model,the each section length of the Great Wall was figured up until the provincial and the national lengths of various types of Great Wall were derived from the section length.the results provided a reference for related studies. |
