Abstract：A rapid volume measurement method for vertical oil tank bottom displacement was proposed to overcome the shortcomings of traditional methods in low accuracy and low repeatability. The 3D point cloud data via 3D laser scanner was used as the study object. The 3D convex hulls construction algorithm based on computational geometry was used to form a 3D convex hull. Then calculate its volume by projection method. In order to verify the accuracy of the rapid method, a vertical oil tank was selected for test,the repetitive error 10 measurements is 1.28%. Then measure it with traditional method,the repetitive error is 11.81%. The relative deviation of two methods was 7.43%.
