Detection method and detection device for marshmallow model of automatic marshmallow machine

The invention relates to a method for detecting a marshmallow model of an automatic marshmallow machine, and the method comprises the steps: collecting an image, and obtaining an original image of a processed marshmallow model; preprocessing the original image, and determining a target edge region; performing contour extraction and screening on the target edge region to obtain a suspicious edge point contour; fitting the contour of the suspicious edge point to obtain the boundary dimension of the marshmallow model; and the obtained boundary dimension is fed back to a controller, and the controller judges whether the boundary dimension of the marshmallow model is qualified or not. According to the detection method and the detection device for the marshmallow model of the automatic marshmallow machine, the processed marshmallow model is detected and judged, a processing scheme is given, customer complaints are reduced, the delivery quality is improved, meanwhile, related personnel such as after-sales engineers
