Objective Comparing the results of high-precision three-dimensional measurement technology with manual measurement experiments, to evaluate the accuracy and accuracy of the high-precision three-dimensional measurement technology for measuring the surface area of commonly used food contact materials. Methods Taking 24 kinds of commonly used food contact materials in 6 categories as examples, the surface areas of the materials were calculated by high-precision three-dimensional measurement technology and compared with the manual measurement data. Results The relative standard deviation of surface area measurement of commonly used food contact materials by manual and high-precision three-dimensional measurement technology was within 6%. Conclusion The high-precision three-dimensional measurement technology has stable measurement results. It can guarantee a certain precision and wide applicability in the surface area measurement of commonly used food contact materials of different materials, and has stable and reliable application prospects.
