摘要
提出一种基于TMS320DM642的嵌入式虹膜识别系统设计方案。该系统集图像采集、图像处理以及图像识别于一体,采用DSP/BIOS嵌入式操作系统,实现对虹膜图像的实时处理。对归一化的虹膜图像采用2D-Gabor滤波器实现特征提取,通过比较海明距实现编码匹配。实验表明,该系统具有识别准确率高、体积小、功耗低以及可靠性高等优点。
In this paper, a kind of embedded iris identification system based on DM642 is put forward. This system has image acquisition, image processing and image recognition .The software system is developed with DSP/BIOS embedded operating system to realize the real-time processing of iris image. With 2D-Gabor filter, the feature of normalized iris images is extracted, and the code is matched by hamming distance. Experiment results show that this system can run efficiently and stalility, which has high i- dentification accuracy, small size and low power consumption.
