“…The measurement of empty volumes, for example tanks, is partially different: anyway, in case of granular materials positioned in closed environments this measurement is complementary and could be used to assess the volume of the material partially occupying a space. Among the papers discussing this problem, some of them use statistical approaches based on electromagnetic fields emission [2] while other focus on acoustic waves [3], laser scanning [4][5][6] or pressure measurements [7].…”

“…Pukanska et al [5] manually extracted the data points of the tank shell and used the point clouds of the top and bottom cross sections to fit the cylinders of the shell. Huadong et al [6] cut the point clouds of the shell walls based on the known elevation and used the least squares method to fit the cylinder to all the sliced point clouds. Liu et al [7] applied TLS to a tank, used Geomagic software to generate the radial error chromatograms of the point cloud and design models, and sliced the point cloud model to fit the center of the circle coordinate using the least squares method to compute the radial deviation, ellipticity, and tilt of the sliced layer.…”

The foundational settlement and deformation of vertical storage tanks are crucial factors influencing their safe operation. To enable rapid deformation assessment of storage tanks, this paper combines point cloud data acquired through terrestrial laser scanning with relevant data processing algorithms to construct a digital twin (DT) model. This achieves high-precision automated detection of tank deformation, facilitating the digital transformation of deformation assessment and offering an integrated detection strategy. First, Euclidean distance clustering is applied to the point cloud, and the point density within clusters is statistically analyzed using a Gaussian distribution. This results in a collection of point clusters within one standard deviation, effectively filtering out outliers and noise points, which facilitates the rapid global registration of the point cloud. Second, in order to quickly segment tank point clouds in the scene, back propagation neural network classification learning based on principal component analysis information is used. The point cloud model is combined with the fitting information of slices to generate a DT model, whose deformation can be evaluated through comparison with appropriate storage tank specifications, taking radial deformation, tank inclination, and foundation settlement as indicators.

Vertical tanks are commonly used appliances for liquids, and its capacity is very important for quantitative liquid ratio and liquid trade. In order to measure the capacity of vertical tanks more conveniently, this paper proposes a vertical tank capacity measurement method based on Monte Carlo Method. The method arranges a plurality of sensor points on the inner surface of the tank, and then performs Monte Carlo tests by generating a large number of random sample points, and finally calculates the capacity by counting the sample points that meet the criterion. The criterion for whether a sample point is located in the tank, which is the core issue, is established with the coordinates of sensor points and the distance between different sensor points along the surface of the tank. The results show that the absolute error of the measurement results of the proposed method does not exceed ±0.0003[m3], and the absolute error of capacity per unit volume has a linear relationship with the height of the vertical tank, and has little effect with the radial size of the vertical tank.
