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

Abstract

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 achieving continuous metering of the bagged materials. According to the invention, the condition of materials in a current warehouse can be seen from the system, a bagged material warehouse-in and warehouse-out metering system is formed, subsequent scheduling is facilitated, and automation of factory operation is realized.

Description

technical field [0001] The invention relates to a material storage and output measurement technology, in particular to a bagged material storage and storage measurement method based on video analysis. Background technique [0002] Many chemicals are used in industrial production, such as ammonium nitrate, etc. These chemicals are flammable and explosive, prone to danger, and endanger the safety of workers. Therefore, these chemicals are strictly controlled by the state. For factories and enterprises, it is particularly important to be able to accurately measure the amount of these chemicals. Because chemicals are flammable and explosive, the scheme based on RFID and forklift weighing requires strict explosion-proof requirements, and the cost is relatively high. [0003] Ammonium nitrate and other materials are dangerous goods controlled by the state, and the usage needs to be strictly controlled. Due to the large number of doors in the warehouse and the frequent entry and ...

Problems solved by technology

Due to the large number of doors in the warehouse and the frequent entry and exit of materials, the current method of artificially counting bags is prone to errors, which makes the inventory of these hazardous chemicals inaccurate and easy to lose, causing a series of problems
