The invention discloses an article tracing method applied to an article tracing system. The system comprises an image acquisition device and a carrying device, wherein the image acquisition device comprises an image acquisition module, a processing unit and a display; the carrying device comprises a control module, a driving module and a carrying base; and the image acquisition device is arranged on the carrying base. The article tracing method comprises the steps of building a connection line between the image acquisition device and the carrying device; acquiring a first sampling image by the image acquisition module, and displaying the first sampling image by the display; appointing an article in the first sampling image to be a tracing article, and acquiring an article coordinate; computing a difference between the article coordinate and a target coordinate of a target position; generating a first control signal according to the difference, and transmitting the first control signal to the carrying device; using the control module to control rotation of the driving module or movement of the carrying base according to the first control signal, and locating the tracing article at the target position. According to the article tracing method provided by the invention, the article can be automatically traced and positioned, and the selfie problem of the existing device is effectively solved.
