To deal with key issues which constrain the development of iris recognition system technology, such as difficulties in i ris image acquisition, bad user friendliness and recognition algorithms rely on image quality, etc, a kind of design of iris recognition system within middle distance based DM3730 is proposed. Firstly, the image acquisition of the system, which is constructed by a high-resolution CMOS image sensor, a LCD feedback unit and focusing model, makes iris acquisition as easy as face acquisi- tion. Secondly, unconstrained iris recognition algorithms are proposed to ensure the effectiveness of the system. Finally, for the DM3730 processor which uses ARM and DSP dual-core architecture, the system software is designed. Experiments show that this system has convenient and efficient image acquisition device, high recognition rate, real-time and strong practical value.
