The invention relates to a method for carrying out intelligent cutting on a pattern by utilizing a cutting machine. The method comprises the following steps: laying pattern clothwithina cutting region by a system; acquiring an image of the pattern on a cloth object in a cutting region through a camera, so as to identify the pattern from the pattern on the object; comparing the pattern with patterns stored in the system; if the acquired pattern is not stored in a memory of the system, storing the acquired pattern into the memory of the system; then generating an automatic instruction generation programaccording to the instruction, converting lines in the patterns into a cutting path, executing the action instruction and storing the instruction; selecting each line needing to be cut in the patterns as a cutting path one by one according to the path stored in the system orthe cutting path obtained in the former step; and cutting the pattern on the cloth by system according to the cutting path. According to the method and the system, streak or plaid dislocation of the cut cloth is avoided, and the beautiful appearance of products manufactured by the cloth is guaranteed.
