A method for locating facilities using a line laser in a mobile photogrammetry system is provided to solve the difficulty of finding a conjugate point covered by an obstacle using a laser and to identify a thickness by exactly acquiring left and right coordinates of the laser on an image. A method for locating facilities using a line laser in a mobile photogrammetry system includes the steps of: loading a line laser between a pair of cameras included in a mobile photogrammetry system(S10); forming a laser line on facilities by the line laser while the mobile photogrammetry system is moving(S20); photographing an image including the laser line once by the pair of cameras while the mobile photogrammetry system is moving and calculating the thickness of the facilities by getting coordinates of both ends of a part illuminated by the laser line(S30); and locating the facilities by selecting the part projected by the laser line in the image acquired by the pair of cameras(S40).
