摘　　要：分析了摄像头工作原理,设计了单片机系统硬件电路原理图,编写了精简的C语言程序代码。提出在行中断信号到来后,按序采集存储该行各像素点图像数据,去除冗余的循环判断语句,节约了采集时间,提高了图像采集效率。为满足特殊场合需要,还设计了由多场图像拼接成一幅图像的数据采集方案程序,以提高图像分辨率。实验结果表明:该程序不仅可以驱动低速51单片机采集摄像头图像数据,也可以在高速STM32等单片机上运行,以进一步提高现有图像采集速度与效率。Due to the high speed of camera in outputting image data and the high frequency of PCLK pixel synchronizing signal,the single chip microcomputer has low efficiency in image data acquisition. This article studies the working principle of the camera,designs the hardware circuit diagram of the single chip microcomputer system,and writes simplified C language codes. After the arrival of the row interrupt signal,the collecting and storing of the pixels image data of the row will be done in order. In the processing,there is no loop statement which is redundant at all. This approach saves the time and improves the efficiency in the data acquisition. This paper also designs the acquisition program to improve the image resolution for the following special case,where the image is made from a number of images. The experimental results show that the program can not only drive at low speed camera image data 51 single-chip microcomputer and can also run on such as high-speed STM32 microcontroller,so it can further improve the existing image acquisition speed and efficiency.
