Abstract

The invention discloses a dead volume and bottom volume measuring method and system based on three-dimensional point cloud and a storage medium. The method comprises the steps of: extracting the bottom boundary of a tank body according to the three-dimensional point cloud data in the tank body; extracting the point cloud data of the bottom portion of the tank body from the three-dimensional pointcloud data according to the bottom boundary of the tank body; repairing the point cloud data of the bottom portion of the tank body according to the preset height information of a reference plate of the tank body; and calculating the dead volume and the bottom volume of the tank body according to the result of the repairing treatment. The bottom boundary of the tank body is obtained by adopting the three-dimensional point cloud data in the tank body to further obtain the point cloud data of the bottom portion of the tank body, the point cloud data of the bottom portion of the tank body is repaired, and finally, the dead volume and the bottom volume of the tank body are calculated and obtained. The measurement speed and the measurement precision are improved, and therefore, the dead volumeand bottom volume measuring method and system based on three-dimensional point cloud and the storage medium can be widely applied to the technical field of measurement and calibration.

Description

technical field [0001] The invention relates to the technical field of metrology and calibration, in particular to a method, system and storage medium for measuring dead volume and bottom volume based on three-dimensional point clouds. Background technique [0002] Vertical tanks are storage and measurement instruments for bulk petrochemical products, and the accuracy of their capacity measurement is of great significance to trade settlement. Vertical tank volume measurement mainly includes girth method, radial deviation method and photoelectric distance measurement method. Among them, the total station measurement automation degree based on photoelectric distance measurement method is relatively high, but the main function of the total station is to accurately measure angle and However, there are disadvantages of long time and low accuracy in surface measurement. [0003] The emergence of three-dimensional laser scanning technology provides a new feasible way for capacity ...
