Image Processing Technology for Integration of Visual Sensing and Information Processing

提出了一种通用的图像预处理方法,可使嵌入式视觉传感器与后端开发系统有效沟通,并可实现灰度计算、图像分割和二值化等基本图像处理功能,设计的变异32位Modbus协议可为低速端口提供高速图像传输。实验结果表明,该方法简单有效,不仅为嵌入式前端处理提供了良好的预处理手段,而且为嵌入式智能视觉开发奠定了基础。

A kind of general technique for image preprocessing is proposed,which can realize effective communication between the vision sensor and the background of development system,and also can achieve the basic functions of image processing such as gray calculation, image segmentation and binarization. Besides, the variation of 32-bit Modbus protocol is designed for high-speed image transmission in the low speed ports. The experimental results demonstrate that this method is simple and efficient, which not only provides a better pretreatment strategy for the embedded front-end processing, but also lays the foundation for the embedded intelligent visual development.
