摘要
给出了在一个微小系统中基于DMCU进行无线图像传输的方法。以DMCU芯片作为控制单元,由摄像头、LCD和无线收发模块三部分组成的无线图像传输系统。主要功能为摄像头采集图像,并通过无线模块传送到LCD上显示。着重对图像的传输进行了研究,设计了有效合理的编码方式,使得在传送大量数据时的误码率达到最小。给出了发送端和接收端的软件流程,实现了图像数据格式和无线传输数据格式之间的转换。
A method of wireless image transmission based on DMCU in micro system is proposed in this paper. It is controlled by DMCU, and composed of a camera, a LCD and a wireless module. Its function is to take an image by camera, transmit it by wireless module and display on LCD. We empha- sized on the study of transmission, designed effective digital encoding to have the minimum bit error rate. The flow chart of transmission and receiving software is given, and it realized the transformation between the format of image data and transmission data.
