The invention relates to a singular point identification method and apparatus. The singular point identification method comprises the following steps of selecting a preset direction grid line containing a to-be-processed target point, and to-be-observed triangular surface elements; obtaining coordinate axis direction grid lines perpendicular to the preset direction grid line, and obtaining auxiliary planes composed of the preset direction grid line and the coordinate axis direction grid lines; obtaining intersecting lines of the auxiliary planes and the to-be-observed triangular surface elements, and when the intersecting lines located in the same auxiliary plane fall on the same side of the preset direction grid line, confirming the to-be-processed target point as a singular point. The singular point can be identified more effectively; and the singular point in to-be-processed intersection points is accurately identified to obtain correct intersection point information. The grid linesdo not need to be re-translated to obtain new intersection points, so that unified description of singular points in different complex structures is realized, the universality is higher, and the griddivision accuracy is improved.
