ActiveMeasuring method for surface areas of materials—Three dimensional area measurement base on hyperspectral imaging
材料表面积的测量 高光谱成像三维面积测量法
Application Summary AI generated
This standard specifies a method for measuring the surface area of materials using hyperspectral imaging combined with three-dimensional reconstruction. It is applied in industries such as materials science, chemistry, and manufacturing for quality control and research, particularly for porous or irregularly shaped materials where traditional area measurement techniques are inadequate. The method is used in laboratory testing and production environments to ensure accurate surface area characterization for coatings, catalysts, and filtration media.
