The invention discloses a hosiery machine knitting needle combined detection device and method based on laser and machine vision. The device comprises a laser emitter, a convex lens and a photoelectric detector which are respectively arranged on the side surface of a needle cylinder of a hosiery machine. Light rays irradiated on a knitting needle by the laser emitter are reflected and then pass through the convex lens to be converged on the target surface of the photoelectric detector; and the photoelectric detector is also connected with a data acquisition card, a computer, a singlechip and arelay in sequence. The relay is further connected with a loom motor. The device further comprises a CCD camera and a light supplement lamp which are arranged on one side of a needle cylinder of a loom. The CCD camera and the light supplement lamp are respectively connected with the computer. The hosiery machine knitting needle combined detection device based on laser and machine vision can accurately and efficiently dete
