Abstract
本发明公开了一种车载显示屏的显示控制方法、系统、电子设备及存储介质。其中方法包括以下步骤：设定第一对应关系，所述第一对应关系包括车内人员人脸信息、指令信息与所述车载显示屏的界面显示方式之间的对应关系；获取当前的车内人员人脸信息和当前的指令信息；根据所述第一对应关系，确定与所述当前的车内人员人脸信息和所述当前的指令信息对应的界面显示方式。本发明可自动控制车载显示屏的界面显示，避免隐私泄露，保证驾驶员的信息安全。
Description
本发明属于车载显示屏的控制领域，尤其涉及一种车载显示屏的显示控制方法、系统、电子设备及存储介质。
目前的车辆上普遍安装有车载显示屏。通过车载显示屏进行一些信息显示，如音乐歌词、导航路线、接收的消息等，已经成为一种用户习惯。
由于车载显示屏通常是安装于车辆前排的中间，所以车上的所有人员均可以看见车载显示屏上所显示的内容，包括了除驾驶员以外的副驾驶或者后排的人员。对于一些聊天消息或其他敏感信息，驾驶员可能是不想让其他人员看到的，但是由于现有的车载显示屏不存在隐私保护机制，这些信息会直接显示在车载显示屏上，这就导致隐私性较差，无法保证驾驶员的信息安全。
发明内容
本发明的一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，通过设定的第一对应关系将车内人员人脸信息、指令信息与车载显示屏的界面显示方式对应起来，通过获取的当前的车内人员人脸信息和当前的指令信息确定与之对应的界面显示方式，自动控制车载显示屏的界面显示，该界面显示方式适应于当前场景下车内人员和控制操作，可以避免隐私泄露，保证驾驶员的信息安全。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，根据车内人员人脸信息是否包含白名单人员的人脸信息以及是否包含不在白名单上的人员的人脸信息区分了多种车内人员情况，还根据指令信息是否包含语音指令信息以及是否包含手动指令信息区分了不同指令信息。依据不同组合的车内人员人脸信息和指令信息设定的第一对应关系，可以适合多种场景下 的界面显示控制，从而起到全面保护隐私，防止信息泄露的作用。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，给出了一种较佳的第一对应关系，限定了当车内人员人脸信息有且仅有白名单人员的人脸信息且所述指令信息包含所述语音指令信息以及车内人员人脸信息有且仅有白名单人员的人脸信息且所述指令信息包含所述手动指令信息时分别对应的界面显示方式。其中，车内人员人脸信息有且仅有白名单人员的人脸信息表明车内很可能只有白名单人员，此时进行界面显示是相对安全的，隐私泄露的风险较低，可以根据语音指令信息或手动指令信息显示界面以满足用户需求。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，进一步限定了根据语音指令信息显示车载显示屏的界面的具体过程，其根据语音指令信息是否白名单人员发出的语音指令信息来判断是否显示车载显示屏的界面，在验证车内人员人脸信息的基础上，增加了语音指令信息的验证步骤，只在语音指令信息是白名单人员发出的情况下显示界面，从而排除了在车内人员人脸信息有且仅有白名单人员的人脸信息的情况下，由不在白名单上的人员发出语音指令信息进行界面显示的可能，进一步提高了显示的安全性。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，给出了一种较佳的第一对应关系，限定了当所述车内人员人脸信息同时包含所述白名单人员的人脸信息和所述不在白名单上的人员的人脸信息，或所述车内人员人脸信息有且仅有所述不在白名单上的人员的人脸信息，或所述车内人员人脸信息同时不包含所述白名单人员的人脸信息和所述不在白名单上的人员的人脸信息时分别对应的界面显示方式。考虑到只要车内包含不在白名单上的人员就存在信息泄露的风险，所以，无论获取到何种指令信息，均不显示车载显示屏的界面。又考虑到车内人员同时不包含所述白名单人员和所述不在白名单上的人员的情况下，不能确定车内究竟有何人员，如果显示车载显示屏的界面，同样有信息泄露的风险，所以无论获取到何种指令信息，均不显示车载显示屏的界面。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在 于，通过设定的第二对应关系，将不显示车载显示屏的界面时指令信息与指令响应方式对应起来，根据第二对应关系确定与所获取的指令信息对应的指令响应方式，实现了在不显示界面的情况下的指令响应，具有既不会泄露隐私，又不影响用户操作的优点。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，给出了一种较佳的第二对应关系，限定了当指令信息包含语音指令信息或手动指令信息时对应的指令响应方式。考虑到语音指令信息可能是白名单人员发出的，所以在不显示界面的情况下语音指令信息是可后台响应的。通过响应语音指令信息，可以实现对后台程序的语音控制，提高操作便利性。通过不响应手动指令信息，不在白名单上的人员既无法看到隐私信息，又无法对显示屏及后台程序进行控制，可提高操作安全性。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，根据所述语音指令信息是否为所述白名单人员发出的语音指令信息，判断是否在后台响应所述语音指令信息，实现了只对白名单人员发出的语音指令信息进行后台响应，在避免隐私泄露的同时，给白名单人员带来操作便利。
本发明的另一个目的在于提供一种车载显示屏的显示控制方法，其优势在于，通过隐私保护开关的开启与关闭控制获取何种信息以及如何进行界面显示，方便用户在隐私保护和不保护的两种模式下进行切换。
本发明的另一个目的在于提供一种显示控制系统，其优势在于，由相机、指令接收设备、车载显示屏、处理器和存储器相配合，通过设定的第一对应关系将车内人员人脸信息、指令信息与车载显示屏的界面显示方式对应起来，通过获取的当前的车内人员人脸信息和当前的指令信息确定与之对应的界面显示方式，自动控制车载显示屏的界面显示，该界面显示方式适应于当前场景下车内人员和控制操作，可以避免隐私泄露，保证驾驶员的信息安全。
本发明的另一个目的在于提供一种显示控制系统，其优势在于，通过语音接收器获取当前的语音指令信息，方便用户指令输入。
本发明的另一个目的在于提供一种显示控制系统，其优势在于，通过按键或触控屏获取当前的手动指令信息，丰富了指令输入形式，增加了控制车载显 示屏显示的方式。
本发明的另一个目的在于提供一种显示控制系统，其优势在于，通过将显示控制系统设置于车辆内，方便获取车内的相关信息(如当前的车内人员人脸信息和当前的指令信息)。
本发明的另一个目的在于提供一种电子设备，其优势在于，利用处理器执行计算机程序，以通过设定的第一对应关系将车内人员人脸信息、指令信息与车载显示屏的界面显示方式对应起来，通过获取的当前的车内人员人脸信息和当前的指令信息确定与之对应的界面显示方式，自动控制车载显示屏的界面显示，该界面显示方式适应于当前场景下车内人员和控制操作，可以避免隐私泄露，保证驾驶员的信息安全。
本发明的另一个目的在于提供一种计算机可读存储介质，其优势在于，利用处理器执行的计算机程序，通过设定的第一对应关系将车内人员人脸信息、指令信息与车载显示屏的界面显示方式对应起来，通过获取的当前的车内人员人脸信息和当前的指令信息确定与之对应的界面显示方式，自动控制车载显示屏的界面显示，该界面显示方式适应于当前场景下车内人员和控制操作，可以避免隐私泄露，保证驾驶员的信息安全。

下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
实施例1
图1示出了本实施例的一种车载显示屏的显示控制方法。其中，车载显示屏指的是车内的显示屏，其具体可以是车辆出厂原装的显示屏，也可以是车辆出厂后加装的显示屏，还可以是放置于车内的手机、平板电脑等用户终端的显示屏。车载显示屏通常固设或利用支架安装于车辆前部，具体可以位于车辆前排的中间。如图1所示，显示控制方法包括以下步骤：
步骤11：设定第一对应关系，第一对应关系包括车内人员人脸信息、指令信息与车载显示屏的界面显示方式之间的对应关系。
步骤12：获取当前的车内人员人脸信息和当前的指令信息。
步骤13：根据第一对应关系，确定与当前的车内人员人脸信息和当前的指令信息对应的界面显示方式。
步骤11中，车内人员人脸信息反映了车内的具体人员，指令信息表示了要对车载显示屏执行的控制操作，界面显示方式包括了是否显示界面，或如何显示界面(如全屏或缩放显示界面)，或显示何种界面(如显示某应用程序界面或操作系统桌面)等等。第一对应关系可以是固定的，或是随实际应用场景可变的，或是根据用户需求自定义的。第一对应关系可以以表的形式进行存储，表中包括不同车内人员人脸信息和指令信息的组合及与之对应的界面显示方式，在步骤13中具体可以通过查表确定与当前的车内人员人脸信息和当前的指令信息对应的界面显示方式。
步骤12中，可以利用车内相机采集实时车内影像，相机视野覆盖或基本覆盖车辆的驾驶位、副驾驶位和后排座位。当然相机视野很可能未完全覆盖车内的每个角落，存在未拍摄到人脸信息但车内实际有人的情况。相机可以是车辆内单独设置的摄像头，也可以是集成于车载显示屏的摄像头(如集成摄像头与显示屏的车载设备)，还可以是车内用户终端的摄像头。通过与相机的通信，可以从相机获取采集的实时车内影像并从实时车内影像中利用人脸识别技术 获取当前的车内人员人脸信息，或者可以从带人脸识别的相机直接获取当前的车内人员人脸信息。
步骤12中，可以利用指令接收设备接收指令信息，不同类型的指令接收设备可以接收不同类型的指令信息，例如语音接收器可以接收语音指令信息，按键或触控屏可以接收手动指令信息。指令接收设备可以是车辆内单独设置的指令接收设备，也可以是集成于车载显示屏的指令接收设备(如集成语音接收器、按键和显示屏的车载设备，或集成语音接收器、触控屏的车载设备)，还可以是车内用户终端的指令接收设备。通过与指令接收设备的通信，可以从指令接收设备获取当前的指令信息。
本实施例的方法通过设定的第一对应关系将车内人员人脸信息、指令信息与车载显示屏的界面显示方式对应起来，通过获取的当前的车内人员人脸信息和当前的指令信息确定与之对应的界面显示方式，自动控制车载显示屏的界面显示，该界面显示方式适应于当前场景下车内人员和控制操作，可以避免隐私泄露，保证驾驶员的信息安全。
在一种可选方式中，车内人员人脸信息包括：是否包含白名单人员的人脸信息，以及是否包含不在白名单上的人员的人脸信息。其中白名单人员可以是由驾驶员自行设定的，白名单人员的数量不限于1个，例如包括驾驶员本人和驾驶员信任的人。白名单人员的人脸信息可以通过扫描、拍照等方式预先录入，可以根据实际需要增加、删除或修改。如果一个人员不属于白名单人员，那么他就是属于不在白名单上的人员。可以通过将实时车内影像中包含的人脸信息与白名单人员的人脸信息进行比对，判断车内人员人脸信息是否包含白名单人员的人脸信息，以及是否包含不在白名单上的人员的人脸信息。车内人员人脸信息具体可以包括以下4种：
有且仅有白名单人员的人脸信息，即包含白名单人员的人脸信息且不包含不在白名单上的人员的人脸信息；
有且仅有不在白名单上的人员的人脸信息，即包含不在白名单上的人员的人脸信息且不包含白名单人员的人脸信息；
同时包含白名单人员的人脸信息和不在白名单上的人员的人脸信息；
同时不包含白名单人员的人脸信息和不在白名单上的人员的人脸信息。
指令信息包括是否包含语音指令信息，以及是否包含手动指令信息。其中语音指令信息由语音接收器接收，可以是通过语音描述出要执行的操作，如用户直接说“打开某应用程序”，或是指定的语音口令，用户只说“某应用程序”就表示需要打开该应用程序。手动指令信息可以通过按键或触控屏接收，是手动输入要执行的操作，如用户按显示开关键，或在触控屏点击界面显示按钮。通过监控语音接收器、按键和触控屏，可以判断是否接收到语音指令信息或手动指令信息。指令信息具体可以包括：
包含语音指令信息；
包含手动指令信息；
不包含语音指令信息和手动指令信息。
本方式根据车内人员人脸信息是否包含白名单人员的人脸信息以及是否包含不在白名单上的人员的人脸信息区分了多种车内人员情况，还根据指令信息是否包含语音指令信息以及是否包含手动指令信息区分了不同指令信息。依据不同组合的车内人员人脸信息和指令信息设定的第一对应关系，可以适合多种场景下的界面显示控制，从而起到全面保护隐私，防止信息泄露的作用。
在一种可选方式中，第一对应关系可以如表1所示：
表1
上表示出了第一对应关系包括的关系1，关系1为：当车内人员人脸信息有且仅有白名单人员的人脸信息，且指令信息包含语音指令信息时，对应的界面显示方式为根据语音指令信息显示车载显示屏的界面。上述关系1给出了车内人员人脸信息有且仅有白名单人员的人脸信息且指令信息包含语音指令信息时对应的界面显示方式，该种对应关系考虑了这种场景的特点：车内人员人脸信息有且仅有白名单人员的人脸信息表明车内很可能只有白名单人员，语音指令信息很可能是白名单人员发出的，所以进行界面显示是相对安全的，隐私泄露的风险较低，可以根据语音指令信息显示界面以满足用户需求。
但同时考虑到可能存在车内实际有不在白名单上的人员但未识别出的情况，为了进一步确保隐私安全，根据语音指令信息显示车载显示屏的界面优选包括：
根据语音指令信息是否为白名单人员发出的语音指令信息，判断是否显示车载显示屏的界面，其中，若语音指令信息是白名单人员发出的语音指令信息，则显示车载显示屏的界面，若语音指令信息不是白名单人员发出的语音指令信息，则不显示车载显示屏的界面。具体可以通过比对语音指令信息的声纹与白名单人员的声纹来判断语音指令信息是否为白名单人员发出的语音指令信息，若比对成功，则语音指令信息为白名单人员发出的语音指令信息，若比对不成功，则语音指令信息不是白名单人员发出的语音指令信息。白名单人员的声纹可以预先录入并存储。
本方式在验证车内人员人脸信息的基础上，增加了语音指令信息的验证步骤，只在语音指令信息是白名单人员发出的情况下显示界面，从而排除了在车内人员人脸信息有且仅有白名单人员的人脸信息的情况下，由不在白名单上的发出语音指令信息进行界面显示的可能，进一步提高了显示的安全性。
上表还示出了第一对应关系包括的关系2，关系2为：当车内人员人脸信息有且仅有白名单人员的人脸信息，且指令信息包含手动指令信息时，对应的界面显示方式为根据手动指令信息显示车载显示屏的界面。其中，根据手动指令信息显示车载显示屏的界面可以包括根据手动指令信息操作的对象、手势、动作等显示车载显示屏的界面。关系2给出了车内人员人脸信息有且仅有白名单人员的人脸信息且指令信息包含手动指令信息时对应的界面显示方式，该种 对应关系考虑了这种场景的特点：车内人员人脸信息有且仅有白名单人员的人脸信息表明车内很可能只有白名单人员，手动指令信息很可能是白名单人员发出的，所以进行界面显示是相对安全的，隐私泄露的风险较低，可以根据手动指令信息显示界面以满足用户需求。
上表还示出了第一对应关系包括的关系3，关系3为：当车内人员人脸信息同时包含白名单人员的人脸信息和不在白名单上的人员的人脸信息时，对应的界面显示方式均为不显示车载显示屏的界面。
上表还示出了第一对应关系包括的关系4，关系4为：当车内人员人脸信息有且仅有不在白名单上的人员的人脸信息时，对应的界面显示方式均为不显示车载显示屏的界面。
上表还示出了第一对应关系包括的关系5，关系5为：当车内人员人脸信息同时不包含白名单人员的人脸信息和不在白名单上的人员的人脸信息时，对应的界面显示方式均为不显示车载显示屏的界面。
上述关系3、4、5中，只对车内人员人脸信息进行了限定，也就是说，只要车内人员人脸信息同时包含白名单人员的人脸信息和不在白名单上的人员的人脸信息，或车内人员人脸信息有且仅有不在白名单上的人员的人脸信息，或车内人员人脸信息同时不包含白名单人员的人脸信息和不在白名单上的人员的人脸信息，则无论指令信息是否包含语音指令信息或是否包含手动指令信息，均不显示车载显示屏的界面。
上述关系3、4考虑到车内人员只要包含不在白名单上的人员，就存在信息泄露的风险，所以无论获取到何种指令信息，均不显示车载显示屏的界面。上述关系5考虑到车内人员同时不包含白名单人员和不在白名单上的人员的情况下，不能确定车内究竟有何人员，如果显示车载显示屏的界面，同样有信息泄露的风险，所以无论获取到何种指令信息，均不显示车载显示屏的界面。
上述可选方式给出了多种较佳的第一对应关系，但本实施例的第一对应关系并不局限于此，根据实际需要或为了适应不同的场景，还可以设定其他的第一对应关系，例如放宽显示车载显示屏的界面的条件，如设定当车内人员人脸信息同时包含白名单人员的人脸信息和不在白名单上的人员的人脸信息且指令信息包含语音指令信息时，若语音指令信息为白名单人员发出的语音指令信 息，则显示车载显示屏的界面，否则不显示车载显示屏的界面。
在一种可选方式中，图2示出了本实施例方法的一种可选流程，其在步骤12之前，还包括以下步骤：
步骤111：设定不显示车载显示屏的界面时的第二对应关系，第二对应关系包括指令信息与指令响应方式之间的对应关系。
在步骤13之后，若与当前的车内人员人脸信息和当前的指令信息对应的界面显示方式为不显示车载显示屏的界面，则还包括：
步骤14：根据第二对应关系，确定与所获取的指令信息对应的指令响应方式。
其中，指令响应方式包括在后台响应和不响应。第二对应关系可以是固定的，或是随实际应用场景可变的，或是根据用户需求自定义的。第二对应关系可以以表的形式进行存储，表中包括不同指令信息及与之对应的指令响应方式，在步骤14中具体可以通过查表确定与所获取的指令信息对应的指令响应方式。
本方式通过设定的第二对应关系，将不显示车载显示屏的界面时指令信息与指令响应方式对应起来，根据第二对应关系确定与所获取的指令信息对应的指令响应方式，实现了在不显示界面的情况下的指令响应，具有既不会泄露隐私，又不影响用户操作的优点。
在一种可选方式中，第二对应关系可以如表2所示：
表2
上表示出了第二对应关系包括的关系1，关系1为：当指令信息包含语音指令信息时，根据语音指令信息在后台响应语音指令信息。考虑到语音指令信息可能是白名单人员发出的，所以在不显示界面的情况下语音指令信息是可后台响应的。
但为了验证语音指令信息是否为白名单人员发出的，根据语音指令信息在后台响应语音指令信息的步骤，优选包括：根据语音指令信息是否为白名单人员发出的语音指令信息，判断是否在后台响应语音指令信息，其中，若语音指令信息是白名单人员发出的语音指令信息，则在后台响应语音指令信息，若语音指令信息不是白名单人员发出的语音指令信息，则不在后台响应语音指令信息。
本方式只对白名单人员发出的语音指令信息进行后台响应，在避免隐私泄露的同时，给白名单人员带来操作便利。
上表还示出了第二对应关系包括的关系2，关系2为：当指令信息包含手动指令信息时，不响应手动指令信息。通过不响应手动指令信息，不在白名单上的人员既无法看到隐私信息，又无法对显示屏及后台程序进行控制，可提高操作安全性。
在一种可选方式中，图3示出了本实施例方法的另一可选流程，其在步骤12之前，还包括以下步骤：
步骤112：判断是否开启隐私保护开关，若开启隐私保护开关，则执行步骤12-14；若未开启隐私保护开关，则执行步骤15-16。
步骤15：获取当前的指令信息。
步骤16：根据当前的指令信息确定车载显示屏的界面显示方式。
步骤112中，隐私保护开关可以是实体开关，也可以是虚拟开关，用户可以根据实际需求选择开启或关闭。
步骤16具体可以包括根据当前的指令信息显示或不显示车载显示屏的界面。
本方式通过隐私保护开关的开启与关闭控制获取何种信息以及如何进行界面显示，方便用户在隐私保护和不保护的两种模式下进行切换。
需要说明的是，本实施例所述的显示车载显示屏的界面是指显示指令信息要求显示的特定界面，如语音指令信息要求打开某应用程序，则显示该应用程序的界面。至于在显示指令信息要求显示的特定界面之前，显示屏可能处于熄屏状态或显示锁定界面、系统桌面或其他界面的状态。本实施例所述的不显示车载显示屏的界面是指不显示指令信息要求显示的特定界面，如语音指令信息 要求打开某应用程序，则不显示该应用程序的界面。至于在不显示指令信息要求显示的特定界面之后，显示屏可能进入熄屏状态或进入显示锁定界面、系统桌面或其他界面的状态。
实施例2
图4示出了本实施例的一种显示控制系统。其包括：相机21；指令接收设备22；车载显示屏23；一个或多个处理器24，一个或多个处理器24与相机21、指令接收设备22和车载显示屏23通信；以及存储器25，存储器25被配置成存储指令，当指令被一个或多个处理器24执行时，使一个或多个处理器24执行步骤，步骤包括：
设定第一对应关系，第一对应关系包括车内人员人脸信息、指令信息与车载显示屏的界面显示方式之间的对应关系；
从相机获取当前的车内人员人脸信息；
从指令接收设备获取当前的指令信息；
根据第一对应关系，确定与当前的车内人员人脸信息和当前的指令信息对应的界面显示方式。
