This invention discloses a method for identifying primordia of Agaricus bisporus in industrialized cultivation, relating to the field of industrialized edible fungi cultivation technology. By continuously acquiring images of the culture bed surface and establishing a unified micro-region division system, the same spatial location forms a corresponding continuous data structure at different times. This transforms the originally scattered image information into traceable micro-region temporal data, providing a stable data foundation for subsequent identification. This addresses the problem in existing methods where inconsistent image positions or lack of continuous correspondence hinders evolutionary analysis. By introducing position alignment processing in the image preprocessing stage, images at different times are unified to the same spatial reference system, avoiding positional errors caused by slight camera offsets or changes in acquisition angle. This ensures the consistency of data for the same micro-region in the temporal dimension, allowing grayscale changes to accurately reflect changes in the culture bed surface structure.
