开庭消息传出后,该事件再次引发网友热议:“第一眼看到就觉得是李小龙”“一直以为授权了”“支持维权”。此前,有博主在社交媒体平台表示,因价格战导致门店亏损严重,宝马将从7月起,通过减少销售量来稳定价格,缓解门店的经营压力。对此,宝马中国回应表示,下半年宝马在中国市场将重点关注业务质量,支持经销商稳扎稳打。

电容光学超声波手机指纹识别技术你了解吗2023-04-27 22:31·中科院物理所1你的指纹 我的指纹 全都不一样德国哲学家莱布尼茨说过:世上没有两片完全相同的树叶我们的指纹就像每片树叶上独一无二的叶脉人人皆有终生不变又各不相同正是由于指纹与生俱来的便捷性以及约1/150亿的超低重复率指纹识别技术成为了当今应用最广泛的生物识别技术之一而且与我们的生活息息相关比如在你点开这篇文章的几分钟前是不是用指纹解锁手机了呀2手机是怎么识别指纹的手机需要搭载指纹识别模块其工作过程通常分为三步:采集、处理、匹配采集由传感器负责识别指纹并采集到粗略的指纹图像按采集原理主要分为光学式、电容式、超声波式按采集方式主要分为刮擦式和按压式处理采集到的指纹图像还需要处理先通过灰度均衡、噪点消除、图像增强等方法让指纹的纹路更清晰再通过算法提取指纹的特征数据10个指纹可生成约4900个独立可测量的特征比如环型/弓型/螺旋型纹路图案下的核心点、三角点、纹数、方向、曲率、位置等特征最后将这些由指纹图像形成的特征数据存储为用于模板匹配再次采集并处理指纹后指纹识别模块通过算法将新指纹的特征数据与已有模板进行匹配匹配度高于阈值则通过识别3手机指纹识别技术有哪些小编主要向大家介绍在上述采集过程中传感器对指纹的识别技术电容式指纹识别技术一种成熟的传统指纹识别技术在智能手机领域普及率较高实现原理如下:电容传感器上有N个面积相同的小电容器极板手指可以看作一个大的电容器极板当手指接触电容传感器时就形成了N个小电容器它们的电容值取决于指纹到小电容器极板的距离指纹的嵴(jí)凸起距离极板近电容大;指纹的峪(yù)凹下距离极板远电容小在放电过程中由于电容值不同嵴放电较慢峪放电较快指纹上一条条高低起伏的纹路转换成了电信号从而被准确识别电容式指纹识别有刮擦式和按压式两种采集方式刮擦式类似于全景相机当手指在传感器表面滑动时传感器对指纹拍照再拼接缺点在于手指必须按照特定方向和角度进行匀速滑动导致识别率和便捷性不太令人满意手机上也早已见不到刮擦式指纹识别模块的身影啦按压式作为前者的优化方案相信大家都非常熟悉手指只需按压在传感器上就能快速识别指纹更易于操作起初手机普遍采用将传感器与Home键相结合的前置指纹识别方式但随着大屏、全面屏热潮的掀起手机正面没有多余空间去容纳实体按键了为了不影响屏占比传感器挪到了手机背部但这种后置指纹识别方式需要用户盲按可能一下还按不准不太符合用户习惯许多手机又将传感器与电源键结合出现了侧边指纹识别方式但容易发生误触而且要想指纹的有效识别区域越大手机就越厚指纹识别率与手机轻薄度不可兼得其实对于电容式指纹识别技术无论是刮擦还是按压无论是前置、后置还是侧边在手机外表面必然有一个实体传感器在一定程度上会影响手机外观近年来用户对手机的需求趋于全面大屏、机身轻薄、外形美观等方面手机屏幕也在从LCD屏幕过渡到OLED屏幕基于OLED屏幕的屏下指纹识别方案应运而生将指纹传感器放置于屏幕下方也让用户在进行指纹识别时会有更强的科技感体验屏下指纹识别目前有光学式和超声波式这两种实现方式光学式指纹识别技术是一种生活中常见的指纹识别技术比如应用于考勤的打卡机主要利用光反射原理:手指按压屏幕屏幕发光照亮手指按压区域当光线照射到指纹的嵴和峪时会产生不同角度和明暗程度的反射光线透过屏幕像素间隙被屏幕下的光学传感器接收从而识别出指纹光学式指纹识别技术的优点是:操作方便、穿透性好技术成熟成本不高但也有明显缺点:无法识别皮肤真皮层安全性较低防伪性较差而且屏幕特定区域需要长期发亮增加功耗可能影响屏幕寿命超声波式指纹识别技术是近年来的一种新兴技术类似于声纳原理手指按压屏幕屏幕下的传感器向手指按压区域发射超声波当超声波接触到指纹的嵴和峪时被吸收、穿透、反射的程度有差异会产生不同能量的回波并被传感器接收从而构建出3D指纹图像超声波式指纹识别技术的优点是:穿透性强抗水渍、污渍干扰能力强识别率高支持活体检测安全性较高缺点是:造价高技术相对不太成熟市场占有率低4手机指纹识别技术怎么发展的?大家普遍认为摩托罗拉在2011年4月推出的MB 860是最早搭载指纹识别功能的智能手机用户在手机顶部传感器上进行刮擦式指纹识别大家最熟知的还是苹果在2013年9月发布的iPhone 5S支持前置按压式指纹识别传感器内置在圆形Home键中外圈是不锈钢感应环可以说iPhone 5S引领了手机指纹识别的潮流此后各种支持指纹识别的手机如雨后春笋般进入市场……2014年华为Mate 7:首款支持后置指纹识别的Android手机2015年努比亚Z9尊享版:首款支持侧边指纹识别的手机2018年vivo X20 Plus UD:首款支持屏下光学指纹识别的量产手机2019年三星S10:首款支持屏下超声波指纹识别的手机……据统计数据显示近年来取消指纹识别的苹果机型持续热销影响了指纹识别总体渗透率2022年国内智能手机指纹识别搭载率降至79%其中后置指纹逐渐淡出市场而侧边指纹抢占了绝大部分中低端的LCD屏幕手机市场搭载率为44%屏下指纹识别搭载率为30%其实对于广大用户来说不论是何种指纹识别技术好用才是最关键的目前的屏下指纹识别技术不仅延续了前置识别的便利操作而且无需像后置和侧边识别那样在机身设置传感器凹槽还能让手机实现更极致的轻薄度和屏占比目前市场上已出现了搭载超声波3D广域屏下指纹识别模块的手机可基于双指纹识别实现更多交互功能这也打开了我们的思路原来指纹识别不止于解锁手机和移动支付呀我们每个人有十根手指相当于十把独一无二的钥匙如何使用这些钥匙在手机上打开更多更广的空间呢这是个值得思考的问题~5展望属于指纹识别技术的标签太多:识别率、识别速度、便捷性、安全性、性价比……指纹识别技术的未来走向一定是能够平衡这些指标的更优解不久的将来超声波指纹识别技术可能会成为主流在更远的未来指纹识别技术是否会进化到渗透手指皮肤下提取更多特征进行识别呢转载内容仅代表作者观点不代表中科院物理所立场如需转载请联系原公众号来源:中兴文档编辑:小聪
