基于三维扫描技术陶瓷扁平制品表面积的测量方法

Measurement of Surface Area of Ceramic Flatware Based on 3D Scanning Technology

陶瓷扁平制品铅、镉迁移量的检测涉及到制品与食物模拟物接触面积的计算,此接触面积计算的精确度关系到检测结果的准确性。对一些圆形规则的扁平制品其表面积能够容易获得,但对一些不规则的扁平制品比如勺、筷类其表面积不容易通过常规测量工具测得。本文以勺子为例,提出采用三维扫描技术测量其表面积,通过对勺子制品的三维扫描建立三维模型,然后通过软件Artec Studio对三维模型进行数据计算,从而获得勺子表面积,该计算结果精确可靠。通过本文研究,为不规则陶瓷扁平制品的表面积提供了一种可行的测量方法。

The detection of the release of lead and cadmium from ceramic flatware involves the calculation of the reference surface area in contact with food simulant.The accuracy of the surface area calculation is related to the accuracy of the detection results.The surface area of some round and regular flatware can be easily obtained,but the surface area of some irregular flatware such as spoons and chopsticks cannot be easily measured by conventional measuring tools.Taking the spoons as examples,this paper proposes to measure the surface area by using the 3D scanning technology,establish a three-dimensional model through the 3D scanning of spoon products,and then calculate the data of the three-dimensional model through the software Artec Studio,thus obtaining the surface area of the spoons.The calculation results are accurate and reliable.Through the research in this paper,a feasible measurement method is provided for the surface area of irregular ceramic flatware.
