具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考附图来描述本申请实施例提出的基于前照灯的投影方法、基于前照灯的投影装置、电子设备和非临时性计算机可读存储介质。
图1是根据本申请一个实施例的基于前照灯的投影方法的流程图。如图1所示，该方法包括一下步骤：
S1，采集车辆上每个车辆组件的状态信息。
S2，根据状态信息，判断车辆组件是否存在异常。
S3，当判断出车辆组件存在异常时，从预先的多个异常图像中，选取出与车辆组件的标识信息匹配的异常图像作为待投影的目标异常图像。
S4，通过前照灯将所述目标异常图像投影到车辆当前行驶的前方道路上。
具体地，可预先在车辆中存储每个车辆组件存在异常时对应的异常图像，每个异常图像与对应的车辆组件的标识信息匹配。当车辆的前照灯处于开启状态时，判断车辆处于夜间行驶状态，可通过车辆的CAN(Controller Area Network，控制器局域网络)总线采集车辆组件的状态信息，车辆组件的状态信息可以包括：车速、挡位及驾驶模式、驾驶效率指示表、功率表、电量表、水温表、120km/h报警指示灯、续航里程、水温警告灯、发动机故障警告灯、发动机维修警告灯、机油压力警告灯、自动变速器过热警告灯、充电警告灯、动力电池故障报警灯、智能启停系统指示灯、安全带未系警告灯、车门未关警告灯、驻车制动指示灯等等。然后根据状态信息，判断车辆组件是否存在异常，例如，如果机油压力警告灯处于点亮状态，说明车辆机油压力异常，判断车辆组件存在异常；再例如，如果水温警告灯处于点亮状态，说明水温异常，判断车辆组件存在异常。如果判断车辆组件存在异常，获取异常的车辆组件的标识，并从预先的多个异常图像中选取出与车辆组件的标识信息匹配的异常图像作为待投影的目标异常图像，然后通过前照灯将目标异常图像投影到车辆当前行驶的前方道路上的投影区域内，以使驾驶员快速了解车辆的异常情况。由此，该方法可以将车辆的异常信息通过前照灯投影到车辆当前行驶的前方道路上，驾驶员无需低头即可快速获取车辆的异常状况，大大提高了驾驶的安全性。
下面结合具体地示例描述如何确定投影区域。
具体地，如图2所示，C点为车辆的前照灯能够清晰投影最近点，F为前照灯能清晰投影最远点；D点为驾驶员正常驾驶时人眼所能看到距离车辆最近点，BD距离为d3，β 为人眼观看距离车辆最近点(D点)的视线与路面的夹角，X为驾驶员正常驾驶时人眼与车灯的水平距离，L为人眼相对于路面的高度，β、X与L均可提前测得。投影区域可以是车辆的生产厂商根据大量的实验进行标定的区域。例如，如图2所示，根据tanβ＝L/(X+d3)，可以计算出d3的长度，如图3所示，假定车灯间距为L1，车宽为L2，左右前车灯向内角度分别为α1和α2，重叠距距离的最近距离为d1，最远距离为d2。当α1＝α2时，根据(L1+L2)/2d2＝tanα2，可计算出d2的长度，可将【d3，d2】之间的区域标定为投影区域。
并且，为保证驾驶员能够清晰看清投影的信息，驾驶员可在中控将投影图像在规定的区域内进行调整，以便在不同身高人驾驶时都能够清晰看到投投影信息。在车辆转弯时，前照灯具有自适应功能，投影区域也会在车辆转弯一直呈现在车辆行驶的正前方。在车辆前照灯开启时可自动进行投影，驾驶员可调节投影区域，选择关闭投影功能等设置。
根据本申请的一个实施例，当目标异常图像为两个以及两个以上时，通过前照灯将目标异常图像投影到车辆当前行驶的前方道路上，可以包括：根据目标异常图像的异常等级，确定目标异常图像的投影顺序，控制前照灯按照投影顺序投影每个目标异常图像；或者，获取目标异常图像的识别出的时刻；控制前照灯按照目标异常图像识别出的先后顺序，逐个投影目标异常图像。
具体地，如果目标异常图像较多，且目标异常图像的投影区域重叠，则可以根据目标异常图像的异常等级，确定目标异常图像的投影顺序，对于异常等级较高的图像优先投影，如何划分异常等级可提前进行预设，一般对于车辆的重要系统(制动系统、电动助力转向系统等)，如果其出现异常，一般划为高异常等级。当然，也可根据目标异常图像识别出的先后顺序，逐个投影目标异常图像。
为使驾驶员更快速、清楚的了解车辆的异常状况，在本申请的实施例中，如图4所示，通过前照灯将目标异常图像投影到车辆当前行驶的前方道路上之后，还可以包括：
S5，控制前照灯中投影模块以不同亮度值交替投影；和/或，控制提醒装置发出提醒消息。提醒装置可以为指示灯。
具体地，将目标异常图像投影到车辆当前行驶的前方道路上之后，可以控制前照灯中投影模块以不同亮度值交替投影，以使投影区域出现闪烁，可以控制投影区域闪烁三次，闪烁间隔可以为200ms，每次闪烁时间可以0.5s。后恢复正常，以对驾驶员进行提醒。由于投影都与行车安全息息相关，因此并不是实时都在进行闪烁提醒，可以每隔10min进行一次提醒。
当然，将目标异常图像投影到车辆当前行驶的前方道路上之后，也可控制车辆上相应的指示灯点亮，以对驾驶员进行异常提醒。
根据本申请的一个实施例，通过前照灯将目标异常图像投影到车辆当前行驶的前方道 路上之后，还包括：控制图像传感器采集前方道路上的环境图像；根据环境图像，对前照灯的投影功能进行控制。
进一步地，根据环境图像，对前照灯的投影功能进行控制，包括：从环境图像中，识别前方道路的当前状况；其中，当前状况包括前方道路的道路状况、天气状况和/或障碍物状况；根据前方道路的当前状况，对前照灯的投影功能进行控制。
具体地，通过前照灯将目标异常图像投影到车辆当前行驶的前方道路上之后，控制图像传感器采集前方道路上的环境图像，并从环境图像中，识别前方道路的当前状况。
如果车辆较多，路况比较拥堵时，两车的距离比较近，导致投射的图像不能够完全投射在路面上，或者图像传感器识别到前方存在明显障碍物影响到投影，将自动关闭前照灯的投影功能。
当车辆通过窄路工况时，为保证车辆安全通过，驾驶员需要打开示宽灯，此时自动关闭前照灯的投影功能。当示宽灯关闭时，再自动开启投影功能。当车辆通过路况情况不好的路面(坑洼等等)，则通过优化算法将所投影的图像进行优化，以使驾驶员能够看清投影图像。当下雨时，投影图像受雨水影响较大，投射图像不够清晰，因此，如果根据环境图像识别出处于下雨天气时，将默认关闭前照灯的投影功能。驾驶员可根据自己意向在中控中手动选择开启前照灯的投影功能。雨后路面存在积水，路面积水会在车辆通过时不稳定，导致投影图像模糊不清；如果识别到路面积水，自动关闭前照灯的投影功能，通过积水区后再自行开启投影功能。
在车辆上坡、下坡时，驾驶员的视线与车身处于同一水平面，只能平视视野，可以根据上坡信息将投影区域进行调整，方便驾驶员看到投影信息。前照灯具有弯道自适应照明功能，在转弯时会通过自适应将所投影的图像投影在驾驶员前方的路面上。
除可将车辆组件的异常图像进行投影，还可将车辆组件的其它状态信息进行投影，以使驾驶员清楚了解车辆的当前车况。
根据本申请的一个实施例，上述的车辆的基于前照灯的投影方法还可以包括：通过前照灯将车辆组件的状态信息投影到前方道路上。
进一步地，通过前照灯将车辆组件的状态信息投影到前方道路上，包括：根据状态信息对应的车辆组件，确定状态信息的投影位置；按照投影位置，通过前照灯将状态信息投影到前方道路上。
具体地，当车辆的前照灯处于开启状态时，判断车辆处于夜间行驶状态，可通过车辆的CAN总线采集车辆组件的状态信息，可以包括：挡位及驾驶模式、驾驶效率指示表、功率表、电量表、水温表、120km/h报警指示灯、续航里程、水温警告灯、发动机故障警告灯、发动机维修警告灯、机油压力警告灯、自动变速器过热警告灯、充电警告灯、动力电 池故障报警灯、智能启停系统指示灯、安全带未系警告灯、车门未关警告灯、驻车制动指示灯等等。然后获取预设的每个状态信息的投影位置，并根据投影位置通过前照灯将状态信息投影到前方道路上。
由于状态信息较多，不是所有状态信息都有固定的投影区域，在车辆状态信息区域内，有数个车辆状态信息投影区域，多个状态信息共用一个投影区，如冲突时，则将冲突的状态信息轮流投射在相应区域内。状态信息可由客户自行选择将哪几个投射在路面上，哪几种信息公用一个投影区，以及每种信息投影时间等等。
举例而言，如图5a所示，对于左舵车，车速可以显示在投影区域的中间，以方便驾驶员随时观察车速，车辆的安全相关系统故障显示在车速下方，以方便驾驶员快速获取车辆的异常状况；车辆状态显示在投影区右侧；续航里程显示在上方位置。对于右舵车，状态信息的投影位置可如图5b所示。其中，车辆的安全系统相关故障显示可以包括：驻车制动故障警告灯、制动系统故障警告灯、防抱死制动系统故障警告灯、电子稳定控制系统指示灯、自适应巡航控制系统故障警告灯、盲点侦测系统警告灯、车道偏离指示灯、车道保持指示灯、前碰撞预警及自动紧急制动指示灯、胎压监测系统警告灯、发动机防盗故障警告灯、安全气囊故障警告灯电动助力转向系统故障警告灯等。车辆状态显示可以包括：挡位及驾驶模式、驾驶效率指示表、功率表、电量表、水温表、120km/h报警指示灯、续航里程、水温警告灯、发动机故障警告灯、发动机维修警告灯、机油压力警告灯、自动变速器过热警告灯、充电警告灯、动力电池故障报警灯、智能启停系统指示灯、安全带未系警告灯、车门未关警告灯、驻车制动指示灯等。
可以理解的是，投影分为右前照灯投影、左前照灯投影，将车速、续航里程、安全相关系统故障显示可通过左前照灯投影，车辆状态显示可通过右前照灯投影。
综上所述，根据本申请实施例的基于前照灯的投影方法，首先采集车辆上每个车辆组件的状态信息，然后根据状态信息，判断车辆组件是否存在异常，当判断出车辆组件存在异常时，从预先的多个异常图像中，选取出与车辆组件的标识信息匹配的异常图像作为待投影的目标异常图像，再通过前照灯将目标异常图像投影到车辆当前行驶的前方道路上。由此，该方法可以将车辆的异常信息通过前照灯投影到车辆当前行驶的前方道路上，驾驶员无需低头即可快速获取车辆的异常状况，大大提高了驾驶的安全性。
图6是根据本申请一个实施例的基于前照灯的投影装置的方框示意图。如图6所示，该装置包括：采集模块1、判断模块2、识别模块3和投影模块4。
其中，采集模块1用于采集车辆上每个车辆组件的状态信息。判断模块3用于根据状态信息，判断车辆组件是否存在异常。识别模块3用于在判断出车辆组件存在异常时，从预先的多个异常图像中，选取出与车辆组件的标识信息匹配的异常图像作为待投影的目标 异常图像。投影模块4用于通过前照灯将目标异常图像投影到车辆当前行驶的前方道路上。
具体地，可通过相关的存储模块预先存储每个车辆组件存在异常时的对应异常图像，每个异常图像与对应的车辆组件的标识信息匹配。当车辆的前照灯处于开启状态时，判断车辆处于夜间行驶状态，采集模块1可通过车辆的CAN总线采集车辆组件的状态信息，可以包括：车速、挡位及驾驶模式、驾驶效率指示表、功率表、电量表、水温表、120km/h报警指示灯、续航里程、水温警告灯、发动机故障警告灯、发动机维修警告灯、机油压力警告灯、自动变速器过热警告灯、充电警告灯、动力电池故障报警灯、智能启停系统指示灯、安全带未系警告灯、车门未关警告灯、驻车制动指示灯等等。然后判断模块2根据状态信息，判断车辆组件是否存在异常，例如，如果机油压力警告灯处于点亮状态，说明车辆机油压力异常，判断车辆组件存在异常；再例如，如果水温警告灯处于点亮状态，说明水温异常，判断车辆组件存在异常。如果判断模块2判断车辆组件存在异常，识别模块3获取异常的车辆组件的标识，并从预先的多个异常图像中选取出与车辆组件的标识信息匹配的异常图像作为待投影的目标异常图像，然后投影模块4通过前照灯将目标异常图像投影到车辆当前行驶的前方道路上的投影区域内，以使驾驶员快速了解车辆的异常情况。由此，该装置可以将车辆的异常信息通过前照灯投影到车辆当前行驶的前方道路上，驾驶员无需低头即可快速获取车辆的异常状况，大大提高了驾驶的安全性。
