摘要:
ATmega128系列单片机具有处理速度快，内部功能模块丰富等优点，其数据吞吐率可高达1MIPS／MHz，能够很好地缓解系统在功耗与处理速度上的矛盾。而OV6620作为一种数字摄像头，避免了传统模拟摄像头的消耗MCU资源、功耗大等缺点。文中正是基于这些特点，采用ATmega128单片机，将软件程序通过ISP下载到AVR单片机后，按照原理图连接好电路板及实物，通过OV6620摄像头采集一幅图像，传输到AVR单片机，再对图形进行一定的处理。实验证明所设计的硬件系统能够实现图像的采集、处理以及通信的功能，提高了’图像采集与通信的速率，并保持了较好的图像稳定度
Abstract:
Considering ATmega128 MCU has advantages of good processing speed and rich internal function, and its data throughput rates can be as high as 1MIPS/MHz, it can alleviate the contradiction of system＇ s power consumption and processing speed well. OV6620, as a digital camera, can avoid the shortcomings of traditional analog camera such as MCU resource consumption needing large power. It is based on these characteristics, uses the ATmega128 MCU, after downloads the software program to the AVR via ISP, connects the physical circuit board following the schematic to capture an image by OV6620 camera and transmit to the AVR microcontroller, and then does a certain treatment to the graphics. Experiments show that the design of the hardware systems can realize the image acquisition, processing and communications. This method improves the rates of image acquisition and communication as much as possible, and has a better image stability
