Preparation method of skin whole organ acellular matrix

The invention belongs to the technical field of cell matrix preparation, and discloses a preparation method of a skin whole organ acellular matrix. According to the skin whole organ contour detection method, each facial skin whole organ in a to-be-detected facial image is segmented by adopting an image segmentation method to obtain a segmentation result, and a contour line corresponding to each facial skin whole organ is extracted according to the segmentation result; the contour lines of the whole organs of the facial skin can be obtained through image segmentation, the detection efficiency can be improved, if normal contour line extraction fails, the contour lines are extracted through key point detection, and the detection precision can be improved; meanwhile, by evaluating the vitality of the whole organs of the skin, manpower, material resources and time cost can be greatly saved, the evaluation is not influenced by subjective scoring, and long-term, uniform, accurate and stable scoring can be obtained a
