    In order to measure the three-dimensional shape of a large scale object in a long distance,a three-dimensional shape measurement system based on dual oscillating mirror scanning was designed and implemented. Firstly, the principle and the configuration of the system were presented and the system model was derived. Secondly, the field calibration of the structure parameters of the system was accomplished based on the coordinate transformation by taking pictures of a special planar board from different directions. Finally, the plane board, sphere and curved plaster figures were measured and reconstructed by using Lissajous scanning pattern. The measurement results show that the average errors of the distance between the measuring points and the fitted plane are 0.70 mm and 17.85 mm at the distance of 1 m and 10 m, and the average error of the fitted sphere diameter is 0.51 mm at the distance of 1 m. The system can be used for the three-dimensional shape measurement for large scale objects in the long distance.
