摘要
针对手指静脉识别系统中由于个体手指厚度不同和静脉血管大小差异,细小静脉血管图像难以准确获取的问题,研制了一种能够自动调整采集参数以准确获取手指静脉图像的智能采集装置。详细讨论了采集装置的结构组成、工作原理以及基于模糊控制和多传感器融合的参数调整智能算法。实际应用结果表明,该装置能够较为准确获取不同个体的静脉血管图像,极大提高了原始手指静脉图像的质量。
According to the problem that different thickness of the individual fingers and different veins size for＇finger vein identification system and the problem that it is hard to obtain small vein image accurately, an intelligent finger vein image acquisition device is developed which can automatically adjust parameters and then obtain accurate imagine. The collection device is discussed in detail including structure, working principle and intelligent parameters adjustment algorithm based on fuzzy control and multi-sensor fusion. Practical application shows that the device can be more accurate to obtain veins images of different individuals, which greatly improved the original finger vein image quality.
