In one embodiment, the defect index of the glass to be detected may be obtained by giving corresponding weights to the defect position, the defect type and the defect size according to the importance degree, for example, the weights corresponding to the defect position, the defect type and the defect size are respectively 0.5, 0.2 and 0.3, and the defect index of the glass in the above embodiment is 90×0.5+70×0.2+80×0.3=83.
In one embodiment, according to a preset defect level comparison table, a defect level corresponding to a defect index is obtained as a defect level of the glass to be currently detected, for example, when the defect index is in the range of 0 to 30, the defect level is 1, when the defect index is in the range of 30 to 50, the defect level is 2, when the defect index is in the range of 50 to 70, the defect level is 3, when the defect index is in the range of 70 to 90, the defect level is 4, when the defect index is in the range of 90 to 100, the defect level is 5, and it is possible to set the defect level to be 3 or more as a defective product, and therefore, the defect level of the glass product with the defect index of 83 is 4.
