基于嵌入式的稻米形态特性分析仪的开发

Developing Rice Morphology Analyzer Based on Embedded System

设计了一套基于嵌入式的稻米形态特性分析仪,针对优质稻米品质参数检测的实际需要,在设计稻米图像采集装置的基础上,系统以基于ARM内核的S3C2410平台为硬件开发环境,利用嵌入式Linux系统,通过USB图像驱动程序移植,实现了对稻米图像的采集及保存过程,在此基础上,结合图像处理与模式识别技术,编写相应的图像分析应用程序,获得稻米形态品质的国标参数,实现了对稻米整精米率、垩白粒率、垩白度、粒型的快速无损检测。

In order to satisfy the parameter testing of rice quality,a morphology analyzer for rice based on the Embedded System was developed.Based on design of the equipment to capture rice image,ARM core S3C2410 platform was adopted as hardware environment,and the embedded linux system as software environment.After transplantation of USB image driver,the system fulfilled the image capture and image preservation.Finally,combining image processing and mode-identifying technology,an applicative program was compiled and the GB parameters about morphological indexes of rice were obtained.Results：Based on this system it is realized to test rapidly and nondestructively the parameters about head rice rate,chalkiness degree,chalky grain rate,and rice shape type.
