摘要
为了改善低照度环境下视频监控系统的效果,从人类的视觉系统出发,通过对人类的视觉对比度分辨率进行补偿以增强图像信息,同时以ARM11与LINUX相结合的方式,构建嵌入式监控系统,利用硬件编码有效地提高编码效率,对编码后的H264码流进行RTP打包传输。经测试系统满足实时监控,同时增强了低照度环境下的视频图像的信息。
In order to obtain better monitoring effect ander low luminance environment, based on the human visual system, the image information was enhanced by compensating the human visual contrast resolution. Meanwhile, an embedded monitoring system was constructed with the combination of ARMll and LINUX, so the coding efficiency was greatly improved by the hardware coding. Then the encoded H264 stream was transported with RTP package. Tests results show that the system can realize real-time monitoring under low luminance as well as obtain enhanced video images.
