Smoke box statistical method and device and medium

The invention relates to a cigarette box counting method and device and a medium, and relates to the technical field of cigarette manufacturing. The smoke box statistical method comprises the following steps: acquiring a depth map of a smoke box by using image acquisition equipment; performing depth truncation on the depth map and obtaining a two-dimensional mask on the upper surface of the smoke box; acquiring pixel coordinates of angular points on the upper surface of the smoke box based on the two-dimensional mask; acquiring point cloud of the upper surface of the smoke box according to the depth map and internal parameters of the image acquisition equipment; acquiring three-dimensional coordinates of the angular points based on the pixel coordinates of the angular points and the point cloud; the Euclidean distance is solved through the three-dimensional coordinates of the angular points, and the actual length and the actual width of the smoke box are obtained; acquiring a first distance between the graph
