基于激光扫描的立式金属罐容量计量方法
Volume Measurement Method of Vertical Metal Tank Based on Laser Scanning
摘要
Abstract
According to the traditional large capacity measurement methods have some shortcomings,such as low accuracy,low work efficiency and labor intensity,a volume measurement method for vertical metal tank based on laser scanning is presented.The volume calculation model is established for vertical tank and the concrete implementation process is analyzed.And the key algorithms are researched for the laser point cloud data analysis and process.The volume value is automatically calculated in the different liquids by calculating the cross-sectional area along the horizontal direction of tank and integrating from vertical direction.A vertical tank is selected as the measurement object,which has the nominal capacity of 1 000 m3.It is shown the good repeatability and reappearance of the proposed method.To design an experimental comparison system,the measurement experiment is carried out in three different vertical tanks which has the nominal capacity of 1000 m3,2500 m3 and 5000 m3,respectively.The maximum relative deviation of volume measurement between the proposed method and total station method is 0.0729％,0.0329％ and 0.0582％,respectively.关键词
