Abstract In view of the quality and improper operation of the vertical tank, the deformation of the vertical metal storage tank will affect the normal operation and safe operation of the tank and the accuracy of volume measurement. Application of 3D modeling technology of laser scanning, a new method for deformation measurement of large vertical metal tank analysis based on point cloud data is studied and calculated by the iterative algorithm of geometry radius of each plate. High accuracy of the vertical tank plate model was obtained using the geometric radius calculated. The wall deformation measurement platform is used to measure the deformation parameters of the local area, and the synchronous measurement of the whole and local deformation of the vertical tank plate is realized. A 10104m3 vertical floating roof tank (diameter 79.937m) is used as the experimental study, which verified the effectiveness of this method.
