Problems solved by technology

[0003] The inventors found that in all kinds of food packaging, the accurate measurement of the surface area of ​​the food contact surface of container products is an important basis for the calculation of the migration test results. Although the existing three-dimensional surface area measurement devices are widely applicable, the cost is often hundreds of thousands The cost is too high and the detection efficiency is low for the measurement demand side of the surface area of ​​most containers

Abstract

The invention provides a method and a system for measuring the surface area of a rotating body type container. The method comprises the following steps: acquiring two-dimensional section coordinate data of a measured rotating body along a rotating shaft of the rotating body; performing three-dimensional model reconstruction on the rotating body according to the two-dimensional section coordinate data; according to the reconstructed three-dimensional model, the three-dimensional form surface area of the rotating body is automatically calculated; according to the three-dimensional surface area measuring device, the three-dimensional shape surface area is derived by acquiring the two-dimensional section coordinate data of the three-dimensional measured rotating body along the rotating shaft of the rotating body, and compared with an existing three-dimensional surface area measuring device, the cost of an automatic measuring device is reduced, and meanwhile the measuring efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of surface area measurement, in particular to a method and system for measuring the surface area of ​​a revolving container. Background technique [0002] In the field of food safety, the safety of food packaging is almost as important as the safety of food; due to direct contact with food, chemical components in food packaging may migrate into food or chemically react with food components, causing Food quality declines and even food safety issues, so the safety of food packaging needs to be evaluated through the migration test results of its chemical components. [0003] The inventors found that in all kinds of food packaging, the accurate measurement of the surface area of ​​the food contact surface of container products is an important basis for the calculation of the migration test results. Although the existing three-dimensional surface area measurement devices are widely applicable, the cost is often h...
