Automatic evaluation method for tobacco appearance quality

The invention discloses an automatic evaluation method for tobacco appearance quality, which comprises the following steps of: selecting samples: collecting tobacco samples, and grading the tobacco samples; respectively detecting the contents of chemical components of the tobacco samples of different grades; respectively scoring the appearance quality indexes of the tobacco samples of different grades; carrying out correlation analysis on the contents of the chemical components and the scores of the appearance quality indexes of the tobacco samples of the same grade, and determining a correlation equation between the contents of the chemical components and the scores of the appearance quality indexes in the grade; and based on the correlation equation, determining the score of the appearance quality of a tobacco sample to be subjected to appearance quality evaluation in the grade. According to the method, a scientific statistical method is adopted to carry out correlation analysis on the chemical components a
