Blood collection tube aluminum foil cap state identification method, device, equipment and medium

The invention discloses a blood collection tube aluminum foil cap state recognition method and device, equipment and a medium, and relates to the technical field of image recognition. The method comprises the steps that the position of a blood collection tube is monitored, and an original image of the blood collection tube is collected when the position of the blood collection tube reaches a target detection position; processing the original image by using a preset machine vision algorithm to obtain a first tube opening aluminum foil cap image of the blood collection tube; and performing normalization processing on the first orifice aluminum foil cap image, and then inputting the normalized first orifice aluminum foil cap image into a pre-constructed lightweight deep learning classification network model so as to determine the state of the aluminum foil cap of the blood collection tube by using an identification result output by the lightweight deep learning classification network model.
