Embodiment Construction

[0024] This embodiment provides a dynamic monitoring method for granary grain inventory, including the following steps:

[0025] (1) Collect the actual grain surface image in the warehouse, the grain surface image includes the grain surface area and the reference object above the grain surface area;

[0026] (2) Process the grain-noodle image, identify the grain-noodle region and the reference object in the grain-noodle image, calculate the pixel distance between the grain-noodle region edge and the reference object, and compare it with the grain-noodle region edge and The pixel distance between the reference objects is differenced to obtain the pixel distance difference;

[0027] (3) If the absolute value of the obtained pixel distance difference is greater than the set threshold, it is determined that the amount of stored grain in the warehouse has changed;

[0028] (4) Compare the obtained changes in the amount of stored grain in the warehouse with the corresponding normal...

Abstract

The invention relates to a granary grain inventory dynamic supervision method and device. The method comprises the steps of processing an acquired actual grain surface image in a granary, identifyinga grain surface region and a reference object in the grain surface image, calculating a pixel distance between the edge of the grain surface region and the reference object, and subtracting the pixeldistance from the pixel distance obtained by the previous calculation to obtain a pixel distance difference; if the absolute value of the pixel distance difference between the pixel distances obtainedat the two times is larger than a set threshold value, indicating that the difference between the pixel distances obtained at the two times is larger, and then judging that the grain storage quantityin the granary changes; finally, studying and judging the grain inventory comprehensively by comprehensively applying the normal condition, so that the intelligent study and judgment on the illegal operation and other conditions in the grain reserve inventory storage are achieved, and the grain reserve inventory dynamic supervision effect and efficiency are effectively improved, and accordingly the method is an intelligent supervision method involving automatic identification and automatic supervision, and compared with manual supervision, the method saves the labor cost and improves the supervision efficiency.

Description

technical field [0001] The invention relates to a method and a device for dynamic monitoring of granary grain inventory. Background technique [0002] At present, the supervision of grain inventory is mainly to check the physical account, storage account and financial account of the grain depot manually to check whether the three accounts are consistent, and to calculate the grain inventory through measurement calculation method or weighing method. , because the above method requires a long time for the inspection of a single grain depot, and the efficiency is low, so it is impossible to realize the dynamic supervision of all grain reserves. Moreover, the existing grain inventory supervision methods are all manual supervision, especially the grain surface monitoring methods in the granary are all manual supervision, and the supervision efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a dynamic supervision method for g...
