下面对本发明实施例进行详细介绍。
为了更好的理解本发明实施例，首先对本发明实施例中的光学指纹识别模组的工作原理进行介绍。请参阅图1a，图1a是本发明实施例公开的光学指纹识别模组的工作原理示意图，如图1a所示，包括触控显示屏110和光学指纹识别模组120。其中，光学指纹识别模组120可以发射入射光线，入射光线经过触控显示屏表面与手指接触的区域发生反射，反 射光线被光学指纹识别模组120接收，光学指纹识别模组120可以根据全反射原理识别哪些入射光线与指纹的凸起处(指纹的脊)接触，哪些入射光学与指纹的凹陷处(指纹的谷)接触。
具体请参见图1a中的虚线放大区域，在触控显示屏表面，指纹的脊与触控显示屏表面接触，指纹的谷不与触控显示屏表面接触。当光学指纹识别模组120产生入射光线照射在指纹的谷时，入射光线照射在触控显示屏与空气接触的表面，此时，通过设计入射光线的入射角度，以使该入射光线发生全反射(触控显示屏的材质的折射率大于1，空气的折射率约等于1，设置触控显示屏的材质的折射率大于空气的折射率即可)，此时，光学指纹识别模组120可以接收到较强的全反射光线。当光学指纹识别模组120产生入射光线照射在指纹的脊时，入射光线照射在触控显示屏与手指指纹凸起处接触的表面，此时，入射光线照射在手指的凸起处，发射漫反射，此时，光学指纹识别模组120可以接收到较弱的漫反射光线。光学指纹识别模组120可以根据接收的发射光线的强弱形成指纹图像。
请参阅图1b，图1b是本发明实施例公开的一种移动终端的结构示意图，如图1b所示，该移动终端100包括应用处理器(Application Processor，AP)101、触控显示屏102、光学指纹识别模组103，光学指纹识别模组103的指纹识别区域位于触控显示屏102的第一区域，其中，AP101通过总线104连接触控显示屏102和光学指纹识别模组103。
光学指纹识别模组103，用于当触控显示屏102检测到用户针对第一区域的触控操作时，采集用户的指纹数据，并将指纹数据发送至AP101。
其中，第一区域可以是触控显示屏102的任意一个预设区域，该预设区域可以位于触控显示屏102的左上侧(如图1c所示)、上侧、下侧、左侧、右侧等任意位置，该预设区域的面积大小以满足手指的指纹区能够覆盖为前提。该预设区域的形状可以是圆形、椭圆形、四边形(例如矩形)、手指指纹形状等任意形状，本发明实施例不做唯一限定。
本发明实施例中的触控显示屏102可以是薄膜晶体管液晶显示器(Thin Film Transistor-Liquid Crystal Display，TFT-LCD)、发光二极管(Light Emitting Diode，LED)显示屏、有机发光二极管(Organic Light-Emitting Diode，OLED)显示屏等。
本发明实施例中的触控显示屏102可以包括触控屏和显示屏，触控屏和显示屏层叠设置，且显示屏设置于触控屏的下侧面。
AP101，用于利用预先采集的噪声数据对指纹数据做去噪声处理，得到指纹修复数据，噪声数据为光学指纹识别模组103预先在第一区域没有触控操作时采集得到的。
其中，预先采集的噪声数据可以是光学指纹识别模组103在采集用户的指纹数据之前预先采集的。光学指纹识别模组103预先在第一区域没有触控操作时采集噪声处理。如果第一区域有残留的污染物(例如，指纹痕迹、)覆盖，则会影响光学指纹识别模组103采集的指纹数据的结果。采用本发明实施例，在进行指纹数据匹配之前，将采集的指纹数据进行去噪声处理，对采集的指纹数据进行修复，得到更加贴近真实指纹的指纹修复数据。
AP101，还用于判断指纹修复数据与预先存储的指纹模板数据是否匹配。
AP101，还用于指纹修复数据与预先存储的指纹模板数据匹配时，通过指纹验证。
本发明实施例中，AP101在进行指纹数据匹配之前，将采集的指纹数据进行去噪声处理，对采集的指纹数据进行修复，得到更加贴近真实指纹的指纹修复数据。采用本发明实 施例，可以降低触控显示屏上的第一区域(指纹识别区)残留的污染物对采集的指纹数据造成的影响，进而可以提高指纹匹配成功率。
可选的，噪声数据包括N个噪声数据点，指纹数据包括N个指纹数据点，N个噪声数据点与N个指纹数据点一一对应，AP101利用预先采集的噪声数据对指纹数据做去噪声处理，得到指纹修复数据的方式具体为：
AP101获取第一噪声数据点与第一指纹数据点的第一数据差值，根据第一数据差值对第一指纹数据点进行修复，得到第一指纹修复数据点；其中，指纹修复数据包括N个指纹修复数据点，第一噪声数据点为N个噪声数据点中的任意一个，第一指纹数据点为N个指纹数据点中与第一噪声数据点对应的一个，N为大于或等于2的整数。
本发明实施例中，光学指纹识别模组103可以在检测到用户针对第一区域的触控操作时，采集用户的N个指纹数据点，也可以在第一区域没有触控操作时采集N个噪声数据点，并且N个指纹数据点与N个噪声数据点一一对应。AP101可以获取N个噪声数据点中的第一噪声数据点与第一指纹数据点的第一数据差值，其中，第一噪声数据点与第一指纹数据点相对应，并根据第一数据差值对第一指纹数据点进行修复，得到第一指纹修复数据点。具体的，AP101根据第一数据差值对第一指纹数据点进行修复，得到第一指纹修复数据点的方式具体为：AP101将第一噪声数据点与第一指纹数据点的第一数据差值作为第一指纹修复数据点的数值。例如，光学指纹识别模组103采集第一噪声数据点的值为50，第一指纹数据点的值为150，两者差值为100，则可以将100作为第一指纹修复数据点的数值。
可选的，AP101根据第一数据差值对第一指纹数据点进行修复，得到第一指纹修复数据点的方式具体为：
AP101判断第一数据差值是否大于预设阈值；
若是，AP101将第一数据差值作为第一指纹修复数据点的数值；
若否，AP101不对第一指纹数据点进行修复。
一般而言，光学指纹识别模组103两次采集指纹数据时，两次采集的指纹数据点会有略微的差异。如果第一数据差值较大，则表明第一数据点受噪声影响较大，或者是第一数据点为采集的指纹的凸起处(例如，指纹的脊)的数据，需要对第一数据点进行修复，并将第一数据差值作为第一指纹修复数据点的数值。如果第一数据差值较小，则表明第一数据点受噪声影响较小，无需对第一数据点进行修复。预设阈值可以预先进行设定，比如，可以设定预设阈值为5。实施本发明实施例，可以降低指纹数据修复处理的复杂度，提高指纹匹配的速度。
可选的，光学指纹识别模组103，还用于在第一区域没有触控操作时周期性的采集噪声数据。
其中，光学指纹识别模组103可以周期性的采集噪声数据，例如，周期可以为1分钟，5分钟等等，本发明实施例不做限定。
可选的，AP101，还用于从光学指纹识别模组103获取周期性采集的噪声数据，并将最新采集的噪声数据作为预先采集的噪声数据。
其中，AP101每次从光学指纹识别模组103获取新的噪声数据之后，将新的噪声数据覆盖之前获取的噪声数据，以保证每次指纹修复时，都使用的是最新获取的噪声数据，提 高指纹修复的准确率。
可选的，预先采集的噪声数据为光学指纹识别模组在第一区域没有触控操作时周期性的多个采集噪声数据中的任意一个。
请参阅图2，图2是本发明实施例公开的一种光学指纹识别方法的流程示意图。该方法应用于包括应用处理器AP、触控显示屏、光学指纹识别模组的移动终端，所述光学指纹识别模组的指纹识别区域位于所述触控显示屏的第一区域，如图2所示，该方法包括如下步骤。
201，当触控显示屏检测到用户针对第一区域的触控操作时，移动终端控制光学指纹识别模组采集用户的指纹数据，并将指纹数据发送至AP。
202，移动终端通过AP利用预先采集的噪声数据对指纹数据做去噪声处理，得到指纹修复数据，噪声数据为光学指纹识别模组预先在第一区域没有触控操作时采集得到的。
203，移动终端通过AP判断指纹修复数据与预先存储的指纹模板数据是否匹配，若匹配，则通过指纹验证。若不匹配，则不通过指纹验证。指纹验证可以用于指纹解锁、指纹支付等场景。
本发明实施例中，AP在进行指纹数据匹配之前，将采集的指纹数据进行去噪声处理，对采集的指纹数据进行修复，得到更加贴近真实指纹的指纹修复数据。采用本发明实施例，可以降低触控显示屏上的第一区域(指纹识别区)残留的污染物对采集的指纹数据造成的影响，进而可以提高指纹匹配成功率。
可选的，噪声数据包括N个噪声数据点，指纹数据包括N个指纹数据点，N个噪声数据点与N个指纹数据点一一对应，移动终端通过AP利用预先采集的噪声数据对指纹数据做去噪声处理，得到指纹修复数据的方式具体为：
移动终端通过AP获取第一噪声数据点与第一指纹数据点的第一数据差值，根据第一数据差值对第一指纹数据点进行修复，得到第一指纹修复数据点；其中，指纹修复数据包括N个指纹修复数据点，第一噪声数据点为N个噪声数据点中的任意一个，第一指纹数据点为N个指纹数据点中与第一噪声数据点对应的一个，N为大于或等于2的整数。
可选的，所述移动终端通过所述AP根据所述第一数据差值对所述第一指纹数据点进行修复，得到第一指纹修复数据点的方式具体为：
所述移动终端通过所述AP判断所述第一数据差值是否大于预设阈值；
若是，所述移动终端通过所述AP将所述第一数据差值作为所述第一指纹修复数据点的数值；
若否，所述移动终端通过所述AP不对所述第一指纹数据点进行修复。
