本课题旨在将机器视觉技术结合机械制造技术和数控加工技术应用于pcb制造机器的设计研发之中,从而可以提高pcb的加工效率和精度,降低生产成本。 - For the image acquisition of optical scan mode , normally , ccd image sensor is used to capture image , but in our system , due to the system request of micromation and high integration , cmos image sensor is adopted as the image collection device , and then the thesis gives a interface circuit between the chip and dsp and a control solution of image collection ; toward the information storage in our solution , dsp is directly linked to usb host chip and it is the dsp that accomplishes the processing of usb protocol and interface control so as to reduce the cost , minimize product cubage and consequently meet the requirement of system micromation ; at the same time , the thesis probes preliminarily into usb otg ( on - the - go ) technology , which offers an approach between embedded machines including pda , mobile phone , printer , digital camera and so on ; in addition , some attempts on the other application area with tms320vc5402 which was commonly used to voice processing and static image processing are done , for example , to arrange the chip to control lcd module directly
在图像的光电扫描输入上，传统方案大部分采用ccd型图像传感器，而在本方案中，根据系统微型化、高集成的特点，使用了cmos图像传感器作为摄像器件，并且设计了该芯片与dsp的一种接口电路以及图像采集控制方案；在信息存储上，本方案采用dsp直接与usbhost芯片连接，由dsp处理usb协议和接口信息，从而降低了系统成本、缩小了产品体积，满足了系统微型化的要求；同时本论文也对usb - otg技术进行了初步探讨，利用此项技术，不再需要计算机作为主机，就能实现在pda 、移动电话、打印机、数码相机等嵌入式应用之间直接互联通信；另外也对广泛用于语音处理和静态图像处理的tms320vc5402其它方面的应用进行了尝试，比如直接控制液晶显示器等。
