摘 要
传统的工业级图像处理采集系统大多是由CCD摄像头、图像采集卡和PC机组成，虽已得到了广泛的应用，但是它具有结构复杂，成本高，体积大，功耗大等缺点。随着单片机的迅速发展，开发一种智能控制及智能处理功能的微型图像处理采集系统成为可能，并且也克服了传统图像处理采集系统的诸多缺点。
本设计提出了基于单片机的图像采集系统，该系统主要由四大模块组成：第一个是单片机控制模块，对摄像头进行控制；第二个是摄像头模块，即进行图像拍摄和取图；第三个是Zigbee无线传输模块，功能是将图像传送到上位机；最后是上位机，实现图像显示功能。其优点是硬件电路简单，软件功能完善，控制系统可靠，性价比较高，使用环境广泛及成本低等。利用Proteus和Keil进行仿真调试，可以看到设计内容的运行结果，验证系统运的行正确及稳定性，并且实现了图像处理采集功能，所以具有一定的实用和参考价值。

Abstract
The traditional industrial image processing collection system by CCD camera, mostly image collection card and PC unit into, although already a wide range of applications, but it has the structure is complex, high cost, big volume and shortcomings, such as big power consumption. With the rapid development of the single chip microcomputer, the development of a kind of intelligent control and intelligent processing function of micro image processing collection system possible, and also overcome traditional image processing collection system of many of the faults.
This design is put forward based on SCM image acquisition system, the system consists of four modules: the first one is the single chip microcomputer control module, the camera to control; The second is a camera module, the image shoot and take diagram; The third is Zigbee wireless transmission module, the function is will images to PC; Finally the PC, realize image display function. Its advantage is hardware circuit is simple, software perfect function, control system and reliable, high cost performance, use extensive and environment cost low status. Use Proteus and Keil simulation commissioning, can see the operation of the design content, as demonstrated the correct and do the system stability, and realize the image processing collection function, so has certain practical and reference value.
