A new method for determining strip structure with digital image analysis was discussed. The results showed that: 1) digital image analysis method could be used to determine strip structure; the test precision of the method ranged from 1.31 to 31.91 mm2, which depended on strip area; 2) The relative error of the method was less than 1 % when strip area was larger than 817.95 mm2; while which was less than 4 % when the area was smaller than 361.00 mm2; 3) The amount of sample should be no less than 1500 g.
