Abstract A volume measurement method for spherical tank based on laser external scanning is presented. The method is applied to scan the outside of spherical tank at multi-point station. And the point cloud data automatic splicing method is studied based on the spherical target, so the full point cloud data can be got for the outer wall of the spherical tank. Then the geometry space model of spherical tank is established, and tank volume is calculated. Through the test of a spherical tank with the capacity of 200 m3, the volume measurement relative error between the proposed method and total station method is 0.304%.
