Abstract

The invention discloses a point cloud collection method, system and storage medium in a multi-site tank without markers. The method includes: moving a point cloud collection device to a preset position; performing a positioning operation on the point cloud collection device to generate positioning information; Based on the preset total number of sampling sites, determine the positions of several sampling sites according to the positioning information; control the point cloud acquisition device to arrive at the several sampling sites one by one for point cloud collection; collect the point clouds collected on several sampling sites Synthesize to obtain a complete point cloud of the tank. The invention does not need manual site marking and manual three-dimensional scanning, has low cost and high efficiency, and can be widely used in the technical field of measurement calibration.

Description

technical field [0001] The invention relates to the technical field of measurement and calibration, in particular to a method, a system and a storage medium for collecting point clouds in multi-site tanks without markers. 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, photoelectric ranging method and point cloud reconstruction method based on three-dimensional laser scanning. The girth method needs to build scaffolding outside the tank, and use the girth to measure the circumference of each layer of the tank wall ring plate, and then calculate the layered volume, which requires a huge amount of work. The radial deviation method and the photoelectric ranging method independently measure the circumference of each layer of ring p...
