摘　　要：针对考试替考现象以及考场作弊行为,提出了基于ARM和DSP双核处理器的硬件架构。对指纹细节点进行Delaunay三角剖分,利用三角形检索方法进行指纹特征值的快速查询,从而实现对考生身份的识别。采用x264开源算法处理视频图像,通过视频监控技术对考场情况进行观察。Aiming at the problem of surrogate exam-takers and cheating at examinations,the paper presents hardware framework based on ARM and DSP. After triangulation of fingerprint minutiae,the minutiae points are quickly searched by triangle indexing,and the candidates for an examination are identified through the fingerprint identification technology x264 open source algorithm is used to handle the video,and thus implement a close watch of exam room.
