The invention discloses an abnormal nozzle detection method, device and equipment based on machine vision, and relates to the technical field of ink-jet printing. According to the method, a first detection image is printed on a printing medium to obtain a second detection image, the first detection image comprises at least one preset mark image, and the preset mark image comprises nozzle channel information at least printing the first detection image; and then the second detection graph on the printing medium is collected, and the position of the abnormal nozzle is determined according to a preset mark graph in the second detection graph. According to the invention, the first detection graph containing the preset mark graph is arranged, and the position of the abnormal nozzle is obtained by using the machine vision technology and the preset mark graph, so that compared with the traditional detection graph and detection method, the accuracy and efficiency of abnormal nozzle identification are improved. 本发明公开了一
