The invention belongs to the field of video monitoring, video image processing and analysis technology, and machine vision technology, and in particular relates to a method for estimating the volume change rate of stockpiles based on image features. The method for estimating the volume change rate of stockpiles based on image features is characterized in that it includes the following steps: (1), according to the images captured by the camera, obtain the images collected by the front end; (2), according to the obtained images, set the reference pile (3) Analyze the image of the reference stockpiling state, and estimate its reference volume; (4), after reaching the set time, estimate the stockpiling volume again; (5), use the volume value obtained twice to calculate the volume rate of change. The beneficial effects of the present invention are: realize the intelligent supervision of stockpiling in industry, greatly reduce the input cost, can automatically detect the volume change rate of stockpiling in real time, without manual measurement and detection, and avoid installation and maintenance of measuring equipment, complicated operations, etc. process.
