Abstract :
This study used the key-point observed simultaneously on two images and on two-dimensional intensity image data, which was obtained along with the two points (Point Cloud) data that were approached for automatic focus among points on terrestrial LiDAR data, and selected matching point through SIFT algorithm. As testing the building of College of Science at Konkuk University, the difference of the transformed parameters between the one through automatic matching and the one by hand showed -5mm~5mm, which concluded to be used as the data for automatic focus.
