China is the world’s largest producer and consumer of rice. There are many types of rice in the country and there are a large number of them. Although there are many choices for people’s lives, they have brought many kinds of rice to storage, processing, and testing. inconvenient. The survey found that the most important issue is that the quality inspection of rice has always had problems such as heavy workload, low accuracy, and low work efficiency, which has affected the development of other work. The modern use of rice quality judging instrument instead of manual detection can effectively solve the problem of rice appearance quality detection, which is of great significance for the development of rice industry. Rice quality judgement instrument is a professional instrument that uses machine vision to carry out the appearance quality test of rice. The instrument can be used to detect the percentage of polished rice, chalky grains, chalkiness and grain type (length-width ratio) in rice and rice quality indicators. , Imperfect grain, different grain grain, yellow grain rice and other important indicators, after practical application shows that the use of rice quality judgement instrument can effectively replace the artificial accurate and objective evaluation of appearance quality indicators, especially for scientific research institutes, testing units, Grain distribution companies, processing companies, etc. Because the application of rice judger to detect rice appearance quality has the following main features and obvious advantages. 1. The detection method meets the requirements of domestic standards and specifications. Rice and rice have strict quality according to the national standards GB 1350-2009 "Rice", GB/T 17891-1999 "Quality Rice", and GB 1354-2009 "Rice". Evaluation indicators and evaluation methods, and rice quality judgement R & D is fully taking into account China's rice quality related and standard requirements, so the detection method can fully meet the current use of domestic standards and norms. 2. High test efficiency High quality rice judger Objectively, quickly and accurately detect appearance indicators of rice and rice quality, avoid subjective errors of manual monitoring, greatly improve the accuracy of detection, and ensure the authenticity and effectiveness of rice quality judgment. Sex. 3, the detection speed is fast Because the rice quality judgement instrument uses the machine vision examination, uses the computer special-purpose software to process the data, gave full play to the computer fast characteristic, the whole examination process uses the time is short, the examination speed is very fast, has effectively improved the rice classification storage Efficiency of rice appearance quality testing during processing, processing and trading. 4. Easy to use and convenient to use The quality of rice judger is easy to operate and easy to use. After simple training, it can be used for posts and has a wider range of applications. It meets the requirements for rice quality inspection in different regions and fields.
