The invention provides a method for planarization processing of three-dimensional data of a brain. The method comprises the following steps: obtaining a three-dimensional model related to the brain through scanning equipment, wherein the three-dimensional model comprises the three-dimensional data of the brain; marking a plurality of regions of the three-dimensional model of the brain to distinguish the plurality of regions; and mapping the three-dimensional model of the brain to a unit disc in an area-preserving manner to form an area-preserving mapping graph, wherein the area-preserving mapping graph includes a plurality of marked regions. The three-dimensional brain model can be converted to the unit disc of the two-dimensional plane, so that the brain model can be compared with a reference brain model, and a doctor can judge the part and degree of cerebral lesion accurately.
