将字节转换为FMD（指纹数据） [英] Convert byte to FMD (Fingerprint Data)

问题描述

大家好..



我正在处理指纹设备。我正在创建一个应用程序，它将指纹数据以字节（longblob）格式保存到数据库，现在已经成功。我的问题是，我将对新捕获的商店指纹数据进行验证或识别，我无法比较它，因为数据库中的指纹数据存储是字节格式，而新捕获的指纹数据是Fmd格式。



你能帮我把字节转换成Fmd格式吗？



谢谢大家一如既往..上帝保佑！

Hi to all ..

I am dealing with fingerprint device. I am creating an application which saves fingerprint data to database in bytes (longblob) format which is successful now. My problem is that, i am going to make a verification or identification of the store fingerprint data to the newly captured one and i cannot compare it since the fingerprint data store in database is in bytes format and the newly captured one is in Fmd format.

Can you help me in converting bytes to Fmd format?

Thank you all as always.. God bless!
