Embodiment Construction

[0032] The present invention will be further described in detail below in combination with details, so that those skilled in the art can implement it with reference to the description.

[0033] The present invention provides 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 is directed towards the diagonal direction of the granary. Grain surface, 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, that is, the height change of the three-dimensional space. If the height of any feature point changes Exceeding the set threshold of the first range, check whether the warehouse status is in or out within a certai...

Abstract

The invention discloses a grain storage quantity monitoring method based on vision. The method comprises steps that binocular vision snapshot equipment is arranged at a top portion of an inner warehouse at a gate of a grain storage enterprise granary, the binocular vision snapshot equipment is made to face a grain surface of the grain storage enterprise granary, multiple characteristic points are randomly arranged at the grain surface in a shooting scope of the binocular vision snapshot equipment, height of the characteristic points is monitored at each time interval, if height change of any characteristic point surpasses a set first scope threshold, whether a state of the granary within a certain time scope is in warehouse incoming/outgoing states is checked, if not, the first-level alarm information is emitted. The invention further discloses a grain storage quantity monitoring device. The method is advantaged in that height of the multiple characteristic points of the grain surface is analyzed through utilizing a video analysis method, and functional diversity, operation convenience, low cost and low network requirement are realized.

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...
