Abstract

The invention discloses a high-speed and high-precision tank volume measurement method and device based on three-dimensional laser scanning. The method comprises the steps of making an experimental scheme and controlling the data collection quality; collecting and acquiring three-dimensional point cloud data of the outer surface of a tank through a three-dimensional laser scanning platform; carrying out spatial three-dimensional modeling and establishing a three-dimensional model of the tank through the acquired three-dimensional point cloud data of the outer surface of the tank; analyzing the three-dimensional model of the tank and calculating the volume of the tank through the section method. According to the method, the volume of tanks such as tank trucks, storage tanks and tank containers can be quickly and accurately measured, operation is simple, the safety is high, the labor intensity is low, the data processing time is greatly shortened, influence of materials of the tanks and the like is reduced, and data calculation is convenient. The method can adapt to different work environments and is particularly suitable for the quality supervision department to calibrate and retest the volume of the tanks quickly.

Description

technical field

[0001] The invention relates to a fast and high-precision tank volume measurement method and device based on three-dimensional laser scanning, belonging to the technical field of tank volume measurement. Background technique

[0002] The tank body is the main transportation and storage tool for liquid, liquefied gas and other products in the petrochemical industry, and it is also a measuring tool for trade settlement. According to JJF1009-2006 "Terms and Definitions of Volume Measurement", volume meters include liquefied petroleum gas tank trucks, tank trucks, tanks and barrels, vertical metal tanks, horizontal metal tanks, spherical metal tanks, etc. Among them, automobile tank trucks and oil tank trucks are measuring instruments that are subject to national compulsory verification. The volume verification results are not only the basis for the national transportation authority to formulate safe loading volumes, but also can be used for oil product transfer ...
