To solve the problem that the workload of measuring complex and large components of platforms is large during offshore platforms constructing, this paper puts forward 3d photogrammetry. With the help of the matlab calibration software tooibox_calib, we calibrate the intrinsic and extrinsic parameters of camera. Then through the measurement of intersected binocular vision, we reconstruct the 3d model of the curved surface.
