Abstract

The invention discloses a grain moisture, thousand grain weight and volume weight detection device based on an image processing technology. The device comprises a workbench, a template, a supporting rod and an image collector; the template is placed on the workbench, uniformly provided with grooves and used for flatly laying grain; the supporting rod is arranged on the workbench; and the image collector is arranged on the supporting rod in a liftable mode and is used for collecting an original image of the grain. The invention further provides a grain moisture, thousand grain weight and volumeweight detection method based on the image processing technology. The grain moisture, the thousand grain weight and the volume weight can be measured accurately and rapidly, so that rapid nondestructive multi-quality parameter one-time detection is realized; the detection is not limited by crop categories and varieties; the difficult problem that the high-moisture grain in the northeast cold region and the southern high-humidity region cannot be rapidly measured is solved; the influence of ambient temperature and humidity is small, so that temperature and humidity correction is not needed innight shift; and the structure is simple, the operation is convenient, the continuity is good, mutual overlapping and interference among grains are avoided, and the detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of grain moisture and quality detection, more specifically, the invention relates to a detection device and method for grain moisture, thousand-grain weight and bulk density based on image processing technology. Background technique [0002] As a large agricultural country, my country is one of the major grain-producing countries in the world. The quality of grain is very important, and the moisture content in grain is one of the important factors affecting grain quality. If the grain moisture is too high, it is easy to cause physiological changes such as fever, mildew and insects, so it is not suitable for storage. Too low grain moisture will lead to a decrease in the organic matter inside the grain and a decrease in the quality of the dry matter, which will affect the quality of the grain. Therefore, rapid and accurate detection of grain moisture can ensure the smooth progress of grain storage, processing...
