It is difficult to measure the volume of flexible elastomer containers because the materials for flexible elastomer containers are soft,elastic and non-transparent,and the appearance of flexible elastomer containers is irregular and flat when used.Therefore,a volume measurement method for flexible elastomer container based on 3D laser scanning technology is proposed.The paper introduces the principle of 3D laser scanning technology and the scheme of scanning system.In this paper,the selection of measurement unit,scanning path planning and resolution setting of scanning system scheme are analyzed in detail,as well as the key contents in the process of point cloud processing such as concatenation,declutter,simplification and volume calculation.And verification test is carried out.The test results show that the 3D laser scanning measurement method is accurate in measuring the volume of flexible elastomer containers,which may solve the problem of measuring the volume of flexible elastomer containers,enrich the volume measurement method and the volume transfer system.
