Method and device for monitoring the quantity of stored grain based on vision

Abstract

The invention discloses a binocular vision-based method for monitoring the quantity of grain stored in grain storage. A binocular vision capture device is installed on the roof of the inner warehouse at the entrance of the granary of a grain storage enterprise, so that the binocular vision capture device faces the grain surface of the granary. A plurality of feature points are randomly set on the grain surface within the shooting range of the binocular vision capture device, and the height of the feature points is monitored at intervals. If the height change of any feature point exceeds the first range threshold set, query Whether the status of the warehouse is in or out of the warehouse within a certain time range, if it is not in the out of warehouse or in the warehouse, a first-level alarm message will be issued. The invention also discloses a grain storage monitoring device. The invention uses the video method to analyze the heights of multiple feature points on the grain surface and calculates the grain quantity in the grain storage, and has the advantages of various functions, convenient operation, low price and low network requirements.

Description

technical field [0001] The invention relates to the technical field of grain storage. More specifically, the present invention relates to a method and device for monitoring the quantity of stored grain based on vision. Background technique [0002] At present, the country is implementing the "grain security project" strategy. It is the top priority of the "grain security" project to ensure the quantity and quality of stored grain through information technology. In the existing technology, when the pressure sensor is used for measurement, a large number of pressure sensors and wiring methods need to be deployed on the ground of the grain depot. The online detection technology of the stored grain quantity is not only high in construction investment, inconvenient to use, but also has a large measurement error. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which...
