The invention relates to a method for detecting defects of metal zipper teeth of a zipper on the basis of the machine vision. According to the method, a detection device consisting of a feeding mechanism, a material position sensor, an image sensor, a stepping motor/servo motor, a lamp box, a feed belt, a sorting mechanism, a stainless steel slide rail, a controller and a control system is utilized to carry out detection; and the zipper to be detected is fed onto a belt platform of the detection device by the feeding mechanism and is detected and positioned by the material position sensor, the image sensor is started to acquire a zipper image, then the image is transmitted to the control system and processed by the control system, and whether the zipper has the defects is compared and judged according to a processing result and the judgment standard. According to the invention, the simultaneous detection on the defects of the metal zipper teeth can be realized, the defect that in the prior art, only a certain
