Infrared image-based identification method for the gradation of rock
Rock grain gradation and gradation identification. Regarding the grain targets extracted via segmentation, it is necessary to judge the grain size interval of each rock grain when drawing the gradation curve. In imaging sampling, only the 2D-grain size is retained; however, grain sieving is a 3D-process.
