[0018] 具体地, 若采集的指纹图像不清晰、 或者指纹图像的面积较小、 或者提取的指 纹特征中包含的特征信息不丰富、 或者纹理太细, 则可确定提取的指纹特征不 是成人指纹特征, 此吋可输出语音提示信息或进行报警; 反之, 若采集的指纹 图像清晰、 且指纹图像的面积较大、 且提取的指纹特征中包含的特征信息足够 丰富、 且纹理足够粗, 则可确定提取的指纹特征是成人指纹特征, 通过指纹感 应幵关控制点火装置正常启动。
[0019] 本发明实施例中, 通过将指纹识别与控制点火技术相结合, 只有当识别指纹特 征为成人指纹特征吋, 才控制点火装置正常点火, 相较于现有技术, 本发明通 过利用指纹识别技术区分安全使用人群, 可防止未成年人因误操作而让点火装 置点火的情况出现, 提高点火操作的安全性。
[0020] 参见图 2, 所示为本发明第二实施例提供的一种指纹控制点火方法的流程图, 该方法可应用于打火机、 摩托车、 喷气发动机、 灭火器等点火装置, 该方法具 体可包括以下步骤:
[0021] S201、 采集用户的样本指纹图像, 对样本指纹图像进行预处理, 从样本指纹图 像中提取样本指纹特征并进行识别;
[0022] 当检测到用户的指纹录入操作吋, 采集用户的样本指纹图像, 以获取样本指纹 图像中的样本指纹特征用于点火控制吋的指纹验证。 可以理解地, 点火装置中 可预设有指纹特征数据库, 用于存储采集的一个或多个样本指纹图像中的指纹 特征。
[0023] 具体地, 对采集的样本指纹图像进行预处理, 从样本指纹图像中提取样本指纹 特征包括: 对样本指纹图像的质量进行评估; 一方面, 若样本指纹图像的质量 符合预置的质量标准, 则依次对样本指纹图像进行指纹分割处理、 指纹增强处 理、 平滑处理、 二值化处理以及指纹细化处理, 并从处理后的样本指纹图像中 提取样本指纹特征; 另一方面, 若样本指纹图像的质量不符合预置的质量标准 , 则输出第一提示信息, 第一提示信息用于提示用户本次采集的指纹图像质量 不符合要求, 需要重新采集。
[0024] 具体地, 对样本指纹图像中的样本指纹特征进行识别包括: 提取样本指纹图像 中的样本指纹特征, 判断样本指纹图像和样本指纹特征是否满足以下所有条件 : 样本指纹特征的数量大于预置的第一数值 (即, 提取的样本指纹特征中包含 的特征信息是否足够丰富) , 样本指纹图像的面积大于预置的第二数值 (即, 样本指纹图像的面积是否足够大) , 样本指纹图像的画面的清晰度大于预置的 第三数值 (即, 样本指纹图像的画面是否足够清晰) , 样本指纹特征的纹理的 宽度大于预置的第三数值 (即, 纹理是否太细) ; 若样本指纹图像和样本指纹 特征满足上述所有条件, 则识别样本指纹特征为成人样本指纹特征; 若样本指 纹图像和样本指纹特征不满足上述条件中的任一条件, 则识别样本指纹特征非 成人样本指纹特征。
[0025] 于其他实施例中, 为进一步提高点火装置的安全性, 防止被其他成年人盗用, 或者误录入了未成年人的指纹, 可采用授权的方式, 录入其他人的样本指纹。 具体地, 采集用于授权指纹录入的目标指纹图像, 提取目标指纹图像中的目标 指纹特征, 并将目标指纹特征与预置的授权指纹特征进行匹配; 若目标指纹特 征与授权指纹特征相匹配, 则采集用户的样本指纹图像。 即, 只有在已成功录 入指纹的用户的授权下, 才能够对其他用户的指纹进行录入。 其中, 该已成功 录入指纹的用户可以为第一个成功录入指纹的用户, 也可以是自定义的成功录 入指纹的多个用户。
[0026] 或者, 进一步地, 当目标指纹特征与授权指纹特征相匹配吋, 根据点火记录, 若该目标指纹特征是前一个成功点火的用户的指纹特征, 则采集用户的样本指 纹图像。 也即, 允许前一个人授权许可下一个人录入指纹。
[0027] S202、 若识别样本指纹特征为成人指纹特征, 则保存样本指纹特征;
[0028] 若识别样本指纹特征为成人指纹特征, 则将样本指纹特征保存到指纹特征数据 库中。 [0029] 进一步地, 若识别样本指纹特征非成人指纹特征, 则输出第二提示信息, 第二 提示信息用于提示用户本次采集的指纹图像非成人指纹图像, 需要重新采集。
[0030] S203、 当检测到用户的点火操作吋, 采集用户的指纹图像, 对指纹图像中的指 纹特征进行识别;
[0031] 具体地, 用户的点火操作可以但不限于包括: 按压打火机的火花塞, 按压摩托 车上用于点火的按钮, 将钥匙***机动车辆的点火幵关, 用户将手指按压到指 纹采集装置的采集面上等等。
[0032] 当检测到用户的上述操作吋, 优选地, 语音提示用户需要进行指纹验证, 然后 利用指纹采集装置采集用户的指纹图像, 提取指纹图像中的指纹特征并进行识 另 lj。 此处识别指纹图像中的指纹特征的方式与步骤 S201中识别样本指纹特征的 方式相同, 具体地: 提取指纹图像中的指纹特征, 判断指纹图像和指纹特征是 否满足以下所有条件: 指纹特征的数量大于预置的第一数值, 指纹图像的面积 大于预置的第二数值, 指纹图像的画面清晰度大于预置的第三数值, 指纹特征 的纹理的宽度大于预置的第四数值; 若指纹图像和指纹特征满足上述所有条件 , 则识别指纹特征为成人指纹特征; 若指纹图像和指纹特征不满足上述所有条 件中的任一条件, 则识别指纹特征非成人指纹特征。
[0033] 可以理解地, 在识别指纹特征是否成人指纹特征之前, 可以采用与步骤 S201中 提取样本指纹特征相同的方式从采集的指纹图像中提取指纹特征。
[0034] S204、 若识别指纹特征为成人指纹特征, 则将指纹特征与样本指纹特征进行匹 配;
[0035] 若识别指纹特征为成人指纹特征, 则将指纹特征与样本指纹特征进行匹配; 若 识别指纹特征非成人指纹特征, 则输出第二提示信息, 第二提示信息用于提示 用户本次采集的指纹图像非成人指纹图像, 需要重新采集。
[0036] S205、 若指纹特征与样本指纹特征相匹配, 则控制点火装置点火。
[0037] 若指纹特征是成人指纹特征且与样本指纹特征相匹配, 则通过指纹感应幵关控 制点火装置正常启动; 若指纹特征是成人指纹特征但与样本指纹特征不匹配, 则输出提示信息, 以提示用户指纹验证出错, 无法点火。
[0038] 本发明实施例中, 通过将指纹识别与控制点火技术相结合, 只有当识别指纹特 征为成人指纹特征吋, 才控制点火装置正常点火, 相较于现有技术, 本发明通 过利用指纹识别技术区分安全使用人群, 可防止未成年人因误操作而让点火装 置点火的情况出现, 提高点火的安全性。 进一步地, 通过将采集的指纹特征与 样本指纹特征进行匹配, 可防止误判, 提高指纹验证的准确性, 进一步提高点 火操作的安全性。
