Abstract In order to accurately measure the irregular deformation for the bottom of the vertical metal tank, a method based on digital terrain model was proposed. The bottom was calculated by the capacity of the triangulated irregular network which was built by three dimensional coordinates. This method will provide useful guidelines for future studies of the bottom deformation under the contour line expressed the undulations of the bottom completely. With a standard of the volumetric method, there is a comparison between the geometric method and the digital terrain model method in this experiment. The experiment results showed that the method is applicable to the bottom measurement of the vertical metal tank. Compared with the geometric method, the relative error was reduced 2.5% averagely.
