基于ADV212的远程图像采集系统设计

针对彩色高清图像远程网络传输带宽需求过大的问题,提出了基于ADV212图像压缩芯片结合FP-GA的压缩、传输解决方案。设计中以彩色高清Bayer格式CMOS作为图像传感器,使用ADV212实现对图像的快速高质量压缩,通过FPGA实现整个系统的控制逻辑,实现对ADV212的配置、驱动以及压缩前图像的分配和压缩后码流数据的打包处理。实验表明该系统可以保证接收图像具有较高的峰值信噪比,能够长期稳定地工作在36Mbyte/s的图像输入条件下,且该系统具有体积小、使用灵活方便、带宽占用低和压缩率可调等优点。

Design of Remote Image Collection System Based on ADV212

To solve the problem of excessive demand for remote network bandwidth when transmit color high-definition image through ethernet, this article gives a compression and transmission solution based on the combination of JPEG2000 Video Codec ADV212 and a FPGA with control logic. This system use a Bayer Pattern CMOS image sensor as data source, use the ADV212 to achieve fast high-quality image compression, the FPGA implements the entire system control logic, such as configuration on the ADV212, pre-distribution image, driving ADV212 under its timing and package the compressed stream. The experiments show that the system can guarantee to receive the image having a high peak signal to noise ratio, long-term stability 36 Mbyte/s image input conditions, and the system is small and easy to use, low bandwidth consumption and the compression ratio is adjustable and so on.
