摘　　要：商品的过度包装,会带来资源浪费与环境污染的问题,且以往对于包装的计量检验多为手工测量结合人工评判的方式,检定精度、效率及其自动化程度较低,已无法满足当今大量的商品包装检测需求。因此,以国家标准GB23350-2009《限制商品过度包装要求食品和化妆品》为依据,提出一种基于图像轮廓提取技术的包装计量检验方法:首先利用美国ogp公司的多元传感器测量装置,采集被测商品的垂直面图像;再将图像传入QVI Portal上位机软件,调用图像轮廓提取算法;最后根据国家计量技术规范JJF 1244-2010《食品与化妆品包装计量检验规则》中的基本测量和计算方法,创新性地运用最小面积外接矩形理论计算商品初始包装体积,判断是否存在过度包装现象。对化妆品类商品进行检定测试,的确能够准确、快速地计算其初始包装体积,大大提高了包装计量检验的精度、效率及其自动化程度。Excessive packaging of commodities will bring the problem of resource waste and environmental pollution.In the past,the measurement and inspection of packaging were mostly manual measurement combined with manual evaluation,and the verification accuracy,efficiency and degree of automation are low,which can no longer meet the needs of a large number of commodity packaging testing.Therefore,in this paper,based on the national standard GB23350-2009“Limit excessive packaging requirements for food and Cosmetics”,a package measurement test method based on image contour extraction technology is proposed.Firstly,the multisensor measuring device of ogp company is used to collect the vertical plane image of the commodity under test.Then the image is passed into QVI Portal PC software,and the image contour extraction algorithm is called.Finally,according to the basic measurement and calculation methods in the national metrological technical specification JJF 1244-2010“Rules for the Measurement and Inspection of Food and Cosmetics Packaging”,the paper innovatively uses the theory of Minimum Area Bounding Rectangle to calculate the initial packaging volume of commodities and judge whether there is excessive packaging phenomenon.The verification test of cosmetics can accurately and quickly calculate the initial package volume,which greatly improves the precision,efficiency and automation of package measurement and inspection.
