摘　　要：制约农业专家系统普及应用的瓶颈是携带方便和操作简单,本文针对便携式农业专家系统的开发,提出了现场采集作物、品种、病害、虫害等数字图像作为专家系统的输入信息,以减少用户的文字输入从而达到简化操作的目的。本文基于ARM 6410开发板和USB摄像头,在Linux环境下通过内核的定制实现了图像采集的软件设计,特别是提出了单帧图像采集的有效方法,最终实现了在飞凌OK6410开发板上对单帧图像的采集、存储及显示。The restricting of the agricultural expert system to popularize and apply is easy to carry and simple operation. Aiming at the portable agriculture expert system development, this paper proposed collecting the digital image of crops, varieties, diseases, pests in real-time as the input information for the expert system. In order to reduce the user＇s text input so as to a- chieve the purpose of simplify the operation. This paper is based on ARM6410 development board and USB camera. In the Linux operating system, we customize the kernel, achieve the software design process of gathering image data, especially we put forward the effective meth- ods on the single frame image acquisition. Finally, we successfully got the image data and dis- play the image on the target board.
