The invention relates to a cigarette production quality control and detection link, and particularly relates to an intelligent detecting method of a soft point and a hard point of a cigarette. The method includes steps of sampling density value data of every cigarette, and performing segmental treatment; combining the batch sampling data in group and forming an average density data matrix; settingan average density upon the technical requirement and controlling the upper and lower limits; judging the soft point and the hard point. Through the detection method, the detection precision of the soft point and hard point of the cigarette during the cigarette production process is further improved; the consumption is reduced and the product quality is improved.
