A method for measuring the structure volume of large objects based on LiDAR

Volume is the key representation of object geometry and shape. In engineering practice, it is frequently necessary to measure the volume of large objects. The volume of such objects is usually more than a few hundreds and even tens of thousands of cubic meters. The traditional method of manual measurement and estimation using shape segmentation not only has huge engineering amount, but also has low efficiency. In recent years, the measurement technology based on LiDAR and binocular vision camera has become more and more mature. Using LiDAR to measure the volume of large objects has become one of the feasible methods. Aiming at the large ellipsoidal structures often encountered in engineering practice, this paper presents a method of object volume measurement based on LiDAR. This method can measure the volume of objects over 10000 of cubic meters. At the same time, the feasibility of the method is proved by applying the method to engineering practice.
