The invention discloses an intelligent identification method for a chemical structural formula. The intelligent identification method comprises the steps of performing picture preprocessing on pictureinformation which is selected by a right button, or picture pixel information which is supplied from screen capturing software, or structure picture information which is manually drawn according to inherent characteristics of the chemical molecule picture; then identifying information such as the coordinate of each atom in the picture, the element name of the atom or a chemical group name which is connected with the atom, the types of different chemical bonds and charge isotopes; gathering the extracted information for generating a data file; and finally drawing the structure of the moleculein a structural formula editor and performing displaying.
