采用活体指纹采集仪采集指纹具有快速建库、即时比对、即时破案的特点,因此活体指纹采集仪在国内警用指纹自动识别系统中得到全面推广应用。但是用活体指纹采集仪采集的指纹图像数据会产生不可预见的、无法矫正的伪随机失真,会丢失细节特征,增加伪特征,应当引起广泛重视。
Fingerprint acquisition using live fingerprint collection has a quick database, real-time comparison, real-time detection of the characteristics of the fingerprint in the domestic fingerprint automatic identification system has been fully popularized applications. However, the fingerprint image data collected by the biometric fingerprinting instrument will produce unpredictable and uncorrected pseudo-random distortion, which will lose the details of the features and increase the false features, which deserves wide attention.
