基于FPGA+DM36X的IP摄像机平台

IP Camera Platform Based on FPGA + DM36X

针对目前安防监控设备动态范围较低的问题,文中提出了基于FPGA和DM36X的高动态范围网络摄像机方案。该方案采用高动态图像传感器进行图像采集,并以FPGA和DM36X作为图像处理的核心。FPGA负责对高动态图像进行增强处理,弥补了DM36X对高动态图像处理的不足,并结合DM36X在视频图像编码及传输上的优势,最终实现1 280×720每秒30帧的高动态范围视频图像的采集、处理和传输。

This article proposes a program of IP camera platform based on FPGA ＋ DM36X for a high dynamic range of security monitoring equipment. The program uses high dynamic image sensor for image acquisition with FP- GA and DM36X as the core of image processing. FPGA is responsible for the high dynamic image enhancement pro- cessing, making up for the lack of DM36X in high-dynamic image processing. The advantage of DM36X in video en- coding and transmission yields a high resolution of 1 280 × 720 at a transmission speed of 30 frames per second.
