The invention relates to an online optimal shearing method for defective steel plates. The shearing method is characterized in that areas of a mother plate are divided, and at least one sub-plate is divided in each mother plate area, so that coordinates of a defect position on a rolling big plate are searched; edge coordinates of all the mother plate areas are inquired, so that the mother plate areas in which defects are distributed can be determined; different shearing strategies are formulated for sequence-type A group plates, partition-type S group plates and flame-cutting type G group plates; and all the defective sub-plates are avoided. In this way, the yield rate of the defective steel plates can be increased, and the feeding cost can be reduced. The method solves the problems in the prior art that the steel plate becomes shorter during shearing if the defect position is far from the head and tail of the rolling big plate; a lot of scrap plates can be generated; defects cannot be processed effectively; and the yield rate of the steel plates is greatly reduced.
