An organic object classification method and an organic object classification device are disclosed. The organic object grading method includes following steps: performing a non-contact measurement procedure to a plurality of organic objects to acquire an original image of each of the plurality of organic objects acquiring a first character data according to the original image of each of the plurality of organic objects, wherein the first character data related to geometric feature values of the corresponding organic object acquiring a grade estimation value of each of the plurality of organic objects according to a grade estimation model and the first character data of the corresponding organic object.本發明揭露一種有機物件的分級方法與有機物件的分級裝置。所述有機物件的分級方法包括下列步驟。對多個有機物件執行一非接觸式測量程序,以取得各該有機物件的原始影像。根據各有機物件的原始影像來擷取一第一特徵資料,其中第一特徵資料關聯於對應之該有機物件的幾何特徵值。依據一分級推估模型與各有機物件的第一特徵資料,以取得各有機物件的一分級推估值。21‧‧‧第一處理影像22‧‧‧第二處理影像23‧‧‧第三處理影像27‧‧‧第七處理影像R1、R2‧‧‧局部區域L1、L2‧‧‧回歸直線L3‧‧‧二次曲線
