Granary grain storage real-time monitoring device and method

Abstract

The invention provides a granary grain storage real-time monitoring device and method, and the method comprises the following steps: S1, data collection: analyzing the data generated by an image according to different states of an incoming and outgoing granary, and carrying out the data conversion, data compensation and data filtering of the data; s2, compensating the multipath interference data according to data characteristics, filtering unqualified data through change of a threshold value, extracting effective data, calculating to obtain ground, grain storage surface and grain storage shadow data, and filtering data edge information; s3, giving a square of five pixel points to traverse the shadow data, detecting the contour through image detection, and forming a ground, grain storage surface and shadow density map; s4, performing mean interpolation and threshold filtering on the ground, the grain storage surface and the shadow density map to obtain a lattice diagram of the shadow and the grain storage area, and obtaining the grain storage surface and the shadow surface density map; and S5, cleaning the data, extracting grain storage surface contours to obtain real storage cargocontours, and performing differential operation on the corresponding contours to obtain grain storage surface data.

Description

technical field [0001] The invention relates to the technical field of grain storage monitoring, in particular to a real-time monitoring device and method for grain storage. Background technique [0002] The food issue is one of the urgent issues attracting worldwide attention. Only with food can a country develop industry, national defense, service industry, scientific and cultural undertakings in a stable and healthy manner. The food issue is not only an economic and people's livelihood issue, but also a development and security issue. With the rapid development of green food and the continuous improvement of people's living standards, green grain storage technology has made great progress in my country. Grain storage technology is developing from traditional grain storage technology to green grain storage technology. At the same time, it is gradually changing from extensive grain transportation Supervision is developing towards refined grain transportation supervision. ...

Problems solved by technology

However, there is currently no general-purpose 3D detection equipment for calculating the irregular contours of stored grain objects. The calculation of grain storage commonly used in the market is based on the number of conveyor belt transmissions. In the case of many transmission tasks, it is easy to get confused, and the calculation exists. mistake
