Bagged material warehouse-in and warehouse-out metering method based on video analysis

The invention discloses a bagged material warehouse-in and warehouse-out metering method based on video analysis. The method comprises the following steps: collecting video image data through video sensing equipment; selecting a region of interest in the video image data as an analysis object and performing preprocessing; training the preprocessed data, and constructing a bagged material image real-time segmentation model; constructing a material real-time segmentation system by using the bagged material image real-time segmentation model, and calculating the area size of each segmentation result to determine a tracking material region; calculating a central point of the tracking material region; drawing a curve for tracking the center coordinates of the material region; calculating the slope and the convergence range of the curve, setting a threshold value, and carrying out material statistics; and constructing a circulation judgment system, filtering out the conditions which do not meet the conditions, and
