Application and Research of Rice Appearance Quality Detector
The appearance quality of rice has always been determined by artificial sensory evaluation. This method has a strong subjectivity, which results in low accuracy and poor repeatability, which limits the implementation of national standards. In recent years, the research of foreign rice and rice quality testing instruments has made great progress. In order to objectively, quickly and accurately detect the quality indicators of rice and rice, and shorten the gap with foreign advanced technologies, it is suitable for domestic use of rice. The appearance quality detector has been developed and applied.
The appearance quality meter of rice is mainly composed of an integral device, an image acquisition device, and an image processing system. The entire array includes a scanning floor and a series of orifice plates of different sizes. Its main function is to quickly arrange the rice before capturing images, improving the detection accuracy and efficiency of the system. The image acquisition device is mainly used to obtain image information of rice samples.
Due to the large uncertainty in the artificial judgment of the appearance quality of rice, even the trained personnel who have been engaged in the work for a long period of time will experience greater deviations. Therefore, the accuracy assessment of the appearance quality meter of rice adopts the analysis method related to the manual detection of authoritative detection units. The judgment result of the instrument has a good correlation with the authoritative detection unit to detect the manual judgment result. The standard error is within 2.5. The instrument can accurately detect the appearance quality of rice and rice and can meet the user's use requirements.
