| Abstract: | According to the characteristic of long span steel room rack slippage of national stadium, three-dimensional coordinates of different places are surveyed by 3D laser scan in the course of slippage. The displacement of survey spot is calculated by survey data and distortion is analyzed through chart. The experiment result shows that the method of 3D laser scan is effective. |
