Problems solved by technology

[0003] The existing methods for measuring the volume of materials in the stockyard mostly use traditional measurement tools, visually inspect the stockpile point, and manually calculate the stockpile volume. Automatic measurement methods are not used, and the labor cost is huge and the accuracy is low.

Abstract

The invention discloses a stock ground material volume measurement method and system, and the method comprises the steps: S1, obtaining the point cloud data of a stock ground material pile through a laser scanner; S2, extracting color features of the point cloud data, and performing coarse segmentation on a stock ground background region and a stock pile target region according to the color features to obtain point cloud data of the stock pile target region; S3, performing fitting registration on the point cloud data of the material pile target area by adopting a coarse registration method anda fine registration method; and S4, according to the point cloud data obtained through fitting registration, calculating the volume of the material pile by using a mode of combining a Monte Carlo method and an integral method, and completing volume measurement. According to the invention, the volume of the material pile can be rapidly and accurately obtained, automatic measurement of the materialvolume of the material pile is realized, the labor cost is reduced, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a method and system for measuring the volume of stockyard materials. Background technique [0002] In large iron and steel enterprises, accurate storage and measurement of materials in stockyards is one of the key factors to reduce the cost of iron and steel enterprises, and is the basis for ensuring the safe production of enterprises. Due to the variety of raw materials and the large volume, iron and steel enterprises have an urgent need for automatic measurement of the volume of materials in the stockyard. In order to accurately manage raw materials, it is first necessary to grasp the volume change of the stockpile in real time. Therefore, it is the primary function of the measurement system to use various sensors to perceive and fuse information to complete reliable volume feedback. [0003] The existing methods for measuring the volume of materials in the stockyard most...
