具体实施方式
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本发明。
图18为根据本发明一个实施例的车辆的防炫目控制方法的总体流程图。如图18所示， 本发明实施例的车辆的防炫目控制方法，包括：
S1：获取目标车辆的图像。
S2：根据所述目标车辆的图像确定所述目标车辆的信息；
S3：根据所述目标车辆的信息实时地调整主车辆照射至所述目标车辆上的防炫目区域。
作为一个具体的示例，目标车辆的信息包括目标车辆的行驶状态，则如图1所示，根据本发明一个实施例的车辆的防炫目控制方法，包括如下步骤：
S101：获取目标车辆的图像。
在具体示例中，可以通过安装在主车辆上的摄像头采集目标车辆的图像，其中，主车辆指本车辆，目标车辆例如为主车辆前方行驶的车辆。
S102：根据目标车辆的图像确定目标车辆的行驶状态。
通过采集目标车辆的图像，可以根据图像分析出目标车辆的行驶状态，例如：根据目标车辆的图像中目标车辆的姿态的变化，可以确定出相应的行驶状态。
在本发明的具体示例中，目标车辆的行驶状态包括但不限于：弯道行驶和进入十字路口等行驶状态。
例如：可以根据图像分析出目标车辆是否进入弯道行驶，即：根据目标车辆的图像中目标车辆的姿态的变化，可以确定出目标车辆是否为弯道行驶。同样，也可以确定出目标车辆是否进入十字路口。
当然，在本发明的其它示例中，也可以通过其它方式判断目标车辆的行驶状态是否为弯道行驶或者进入十字路口。例如：通过导航信息判断前方路况，从而确定出前方的目标车辆是否为弯道行驶或者进入十字路口。
S103：根据目标车辆的行驶状态实时地调整主车辆的大灯照射至目标车辆上的防炫目区域。
需要说明的是，主车辆在开启远光灯的时候，该远光灯可采用DMD(数字化微型反光镜)或者像素灯实现，因此，可实现局部某一个照明区域或某几个照明区域的防炫目。
具体地说，防炫目的实现如下：
根据目标车辆的图像识别目标车辆的类型。即：由于不同车辆的车窗及外后视镜在车辆高度中占据比例不同，在获取到目标车辆的图像后，通过车辆识别算法对车辆进行分类判定，以根据不同的车辆类型确定防炫目区域。
根据目标车辆的类型调整主车辆的大灯照射至目标车辆上的防炫目区域。在具体的示例中，根据目标车辆的类型调整主车辆的大灯照射至目标车辆上的防炫目区域，包括：根据目标车辆的类型确定目标车辆的车窗在目标车辆的高度中的占据比例，例如轿车车窗约 在车高的2/3以上，公交车车窗约在车高的1/3以上，双层公交车的车窗约在车高的1/5以上，卡车车窗约在车高的2/3以上，具体的比例根据实际测试进行标定，同时考虑一定的余量，避免因为颠簸等原因而造成炫目，并将标定的结果储存在车辆中，这样，就可以根据识别到的车辆类型确定车窗在车辆高度中的占据比例。
根据目标车辆的车窗在目标车辆的高度中的占据比例调整主车辆的大灯照射至目标车辆上的防炫目区域，以使所述防炫目区域覆盖所述目标车辆的车窗和外后视镜。
需要说明的是，车辆的大灯为像素式大灯，其投射的区域是一个圆形区域，圆形区域中的每一个小区域都是由大灯里的一个像素控制的，防炫目控制的原理是通过控制像素大灯照射区域内的某一个小区域或者几个小区域的像素光线变暗或者熄灭，达到防炫目的目的。
或者，车辆的大灯为采用DMD(数字化微型反光镜)的大灯，从而可以达到防炫目的目的。
在识别出目标车辆的类型之后，还包括，根据目标车辆的图像，进一步识别目标车辆的车窗位置及外后视镜位置；根据目标车辆的车窗位置及外后视镜位置，进一步调整主车辆的大灯照射至目标车辆上的防炫目区域，以使防炫目区域对应于目标车辆的车窗和外后视镜。
三种不同类型的车辆例如皮卡、货车及轿车相对主车辆对向行驶且位于左车道时的防炫目区域如图3(a)中的黑色部分，即防炫目区域对应于车辆的前方车窗和靠近主车辆一侧的车窗，三种不同类型的车辆相对于主车辆同向行驶且位于右车道时的防炫目区域如图3(b)中的黑色部分，即防炫目区域对应于车辆的后方车窗和靠近主车辆一侧的车窗及外后视镜。由图可见，货车及皮卡车车窗占据车辆的比例较小，所以根据本发明实施例的车辆的防炫目控制方法可以实现最小的盲区。
在具体的示例中，车辆的防炫目控制方法还包括：获取目标车辆的行驶姿态；根据目标车辆的行驶姿态，进一步调整所述主车辆的大灯照射至所述目标车辆上的防炫目区域。
进一步地，根据目标车辆的行驶姿态，确定主车辆的大灯照射到目标车辆上的位置；根据主车辆的大灯照射到目标车辆上的位置，确定需要对目标车辆进行防炫目的目标车窗和目标外后视镜；调整主车辆的大灯照射至所述目标车辆上的防炫目区域，以使防炫目区域对应于目标车窗和目标外后视镜。
具体来说，目标车辆的行驶姿态包括很多种，例如同向行驶、对向行驶、超车、变道及车辆转弯等。目标车辆的行驶姿态不同，主车辆的大灯照射到目标车辆的位置也会不同，目标车辆的不同位置对应着不同的车窗和外后视镜，即防炫目区域，因此，对于目标车辆 不同的行驶姿态，需要对主车辆的大灯进行调整以使防炫目区域对应于目标车窗和目标外后视镜。
以目标车辆转弯为例，根据目标车辆的行驶状态实时地调整主车辆的大灯照射至所述目标车辆上的防炫目区域，包括：如果所述目标车辆的行驶状态为弯道行驶，则根据所述目标车辆的行驶方向的变化而重新定位光线影响区域；根据重新定位的光线影响区域调整主车辆的大灯照射至所述目标车辆上的防炫目区域。
在上述示例中，根据所述目标车辆的行驶方向的变化而重新定位光线影响区域，包括：如果目标车辆与主车辆相向行驶，则光线影响区域由所述目标车辆的前风挡玻璃和临近所述主车辆一侧的侧窗，逐渐变化至所述目标车辆的前风挡玻璃；如果目标车辆与主车辆同向行驶，则光线影响区域由所述目标车辆的后风挡玻璃和外后视镜，逐渐变化至所述目标车辆的后风挡玻璃、临近所述主车辆一侧的侧窗以及临近所述主车辆一侧的外后视镜。
作为一个具体的示例，如图4(a)所示，为目标车辆同向转弯时的防炫目区域变化示意图，当目标车辆还没转弯，与主车辆同一个方向且在主车辆的前方行驶时，主车辆照射到目标车辆的位置为其后方车窗及其外后视镜，因此，此时调整主车辆的大灯使防炫目区域对应于目标车辆的后方车窗及外后视镜；当目标车辆转弯时，主车辆照射到目标车辆的位置为其后方车窗和靠近主车辆一侧的车窗及外后视镜，因此，此时调整主车辆的大灯使防炫目区域对应于目标车辆的后方车窗和靠近主车辆一侧的车窗及外后视镜，如图4(a)所示，防炫目区域的变化是一个从二维到三维的变化过程。
如图4(b)所示，为目标车辆对向转弯时的防炫目区域变化示意图，在目标车辆转弯前，主车辆可能无法照射到目标车辆或者只照射到目标车辆的前方车窗，这时调整主车辆的大灯使防炫目区域对应于目标车辆的前方车窗；当目标车辆转弯时，主车辆照射到目标车辆的位置为其前方车窗和靠近主车辆一侧的车窗，这时调整主车辆的大灯使防炫目区域对应于目标车辆的前方车窗和靠近主车辆一侧的车窗。如图4(b)所示，防炫目区域经历了从二维到三维的过程，然后变成二维，直到逐渐消失。
另外，以经过十字路口为例，根据所述目标车辆的行驶状态实时地调整主车辆的大灯照射至所述目标车辆上的防炫目区域，包括：如果所述目标车辆的行驶状态由与主车辆同向行驶转入路口，则光线影响区域由所述目标车辆的后风挡玻璃变化至所述目标车辆的临近所述主车辆一侧的侧窗。如图5(a)所示，目标车辆向右拐弯，即：防炫目区域由目标车辆的后风挡玻璃变化至目标车辆的右侧车窗，即：此时右侧车窗为临近主车辆一侧的侧窗。
另外，如图5(b)所示，如果所述目标车辆的行驶状态由路口转入与主车辆同向，则 光线影响区域由所述目标车辆的前风挡玻璃和临近所述主车辆一侧的侧窗，逐渐转为临近所述主车辆一侧的侧窗，而后逐渐转为后风挡玻璃；如果所述目标车辆的行驶状态由路口转入与主车辆相向行驶，则光线影响区域由所述目标车辆的前风挡玻璃和临近所述主车辆一侧的侧窗，逐渐转为临近所述主车辆一侧的侧窗。如图5(b)所示，目标车辆向与主车辆相向方向左拐弯，即：防炫目区域由目标车辆的前风挡玻璃和驾驶员一侧的侧窗，逐渐变化至驾驶员一侧的侧窗，然后，逐渐变化至前风挡玻璃和驾驶员一侧的侧窗，从而始终对目标车辆中的驾驶员起到防炫目的目的。
如图6所示，根据所述目标车辆的行驶状态实时地调整主车辆的大灯照射至所述目标车辆上的防炫目区域，包括：如果所述目标车辆的行驶状态由与主车辆同向而掉头，则光线影响区域由所述目标车辆的后风挡玻璃，逐渐转为后风挡玻璃和临近所述主车辆一侧的侧窗，而后逐渐转为临近所述主车辆一侧的侧窗。如图6所示，针对同向车辆突然掉头时，即：由同向行驶变为对向行驶车辆情况，防炫目区域由原来的后风挡及外后视镜防炫目变换为驾驶员侧车窗及后风挡防炫目，然后变换为前风挡及驾驶员侧车窗防炫目控制。从而始终对目标车辆中的驾驶员起到防炫目的目的。
根据本发明实施例的车辆的防炫目控制方法，可以在其他车辆的行驶姿态发生变化时(如进入弯道、过十字路口、掉头)，均能够时刻对其起到防炫目效果，从而，避免因车辆远光灯炫目而造成交通事故，提高车辆在行驶过程中的安全性。
作为另一个示例，目标车辆的信息还包括所述目标车辆的行驶方向和目标车辆与主车辆的相对位置，则如图8所示，根据本发明另一个实施例的车辆的防炫目控制方法，包括如下步骤：
S801：获取目标车辆的图像。
为了实现精确的防炫目控制，可以通过传感器，例如摄像头，获取目标车辆的图像。
S802：根据目标车辆的图像确定目标车辆的行驶方向和目标车辆与主车辆的相对位置。
主车辆根据目标车辆的图像进行数据处理，判定目标车辆的行驶状态是同向还是相向以及车辆是否有超车、变道的行为等，并进一步判断目标车辆与主车辆的相对位置。
S803：根据目标车辆的行驶方向以及目标车辆与主车辆的相对位置实时地调整主车辆的大灯照射至目标车辆上的防炫目区域。
进一步的，如果目标车辆与主车辆同向行驶，则确定需要对目标车辆进行防炫目的目标侧窗和目标外后视镜的位置；根据目标侧窗和目标外后视镜的位置，调整主车辆的大灯照射至目标车辆上的防炫目区域，以使防炫目区域对应于目标车窗、目标外后视镜以及后风挡玻璃。
如图9所示，目标车辆相对于主车辆的位置如图，即目标车辆与主车辆同向行驶，且在主车辆的右前方，当根据目标车辆的图像判定目标车辆的行驶方向和与主车辆的相对位置时，为了实现防炫目的效果，调整主车辆的大灯照射至目标车辆上的防炫目区域，使防炫目区域对应于目标车辆靠近主车辆的侧窗和外后视镜以及后风挡玻璃。
如果同向车辆转弯，如图4(a)所示，当目标车辆还没转弯，与主车辆同向且在主车辆的前方行驶时，主车辆照射到目标车辆的位置为其后风挡玻璃及其外后视镜，因此，此时调整主车辆的大灯使防炫目区域对应于目标车辆的后风挡玻璃及外后视镜；当目标车辆转弯时，主车辆照射到目标车辆的位置为其后风挡玻璃和靠近主车辆一侧的侧窗及外后视镜，因此，此时调整主车辆的大灯使防炫目区域对应于目标车辆的后风挡玻璃和靠近主车辆一侧的侧窗及外后视镜，防炫目区域的变化是一个从二维到三维的变化过程。
进一步的，如果目标车辆与主车辆相向行驶，则确定需要对目标车辆进行防炫目的目标侧窗和目标外后视镜的位置；根据目标侧窗和目标外后视镜的位置，调整主车辆的大灯照射至目标车辆上的防炫目区域，以使防炫目区域对应于目标车窗、目标外后视镜以及前风挡玻璃。
如图10所示为同向车辆突然掉头变为相向行驶的防炫目区域变化示意图，在掉头的过程中，目标车辆上的防炫目区域为靠近主车辆一侧的侧窗和外后视镜以及后风挡玻璃，当掉头结束，目标车辆与主车辆相向行驶，这时调整主车辆的大灯照射至目标车辆上的防炫目区域，使防炫目区域对应于目标车辆靠近主车辆的侧窗和外后视镜以及前风挡玻璃。
如果相向车辆转弯，如图4(b)所示，在目标车辆转弯前，主车辆可能无法照射到目标车辆或者只照射到目标车辆的前风挡玻璃，这时调整主车辆的大灯使防炫目区域对应于目标车辆的前风挡玻璃；当目标车辆转弯时，主车辆照射到目标车辆的位置为其前风挡玻璃和靠近主车辆一侧的侧窗以及外后视镜，这时调整主车辆的大灯使防炫目区域对应于目标车辆的前风挡玻璃和靠近主车辆一侧的侧窗以及外后视镜。如图所示，防炫目区域经历了从二维到三维的过程，然后变成二维，直到逐渐消失。
在具体的示例中，目标车辆和主车辆相向行驶时还存在目标车辆驶入照明区域但还没有进入传感器识别区域的情况。通常，车辆的行驶轨迹通过识别算法进行预测，并对防炫目区域通过跟随平移的方式实现，根据遮蔽区域的变化趋势对遮蔽区域进行延伸直至车灯控制边界，车灯控制防炫目区域变化过程示意图如图11所示。考虑到车灯照射区域与传感器识别区域之间存在“盲区”，如图12所示，可以通过检测主车辆和目标车辆的速度计算需要的延迟时间，假设盲区距离为d，设定车辆长度为L，主车辆车速为V1，目标车辆车速为V2，则目标车辆经过“盲区”需要的时间为t＝(d+L)/(V1+V2)，考虑到目标车辆距离 主车辆的远近不同以及车辆的宽度不同，可以设定延迟时间大于t，例如设定延迟时间为2t或3t甚至更长，以弥补各种误差。
另外，当目标车辆和主车辆同向或相向行驶的过程中出现加减速的情况时，可以通过传感器(如雷达、摄像头)检测同向或相向车辆与主车辆的间距，将该间距与标定好的距离进行对比，并同比例的对标定好的距离对应的防炫目区域进行放大或缩小处理，即可确定当前的防炫目区域的范围。
防炫目区域的横向角度与车辆间距的关系如图13所示，如果标定的车辆距离为d1，则防炫目区域对应的横向角度α1＝arctan(L/d1)，其中，L为防炫目区域的实际宽度尺寸，d1为目标车辆与主车辆的距离，同理，如果标定的车辆距离为d2，则防炫目区域对应的横向角度α2＝arctan(L/d2)；防炫目区域纵向角度与车辆间距的关系如图14所示，如果标定的车辆距离为d1，则防炫目区域对应的纵向角度β1＝arctan(H/d1)，其中，H为防炫目区域的实际高度尺寸，d1为目标车辆与主车辆的距离，同理，如果标定的车辆距离为d2，则防炫目区域对应的纵向角度β2＝arctan(H/d2)。
即当目标车辆和主车辆同向或相向加减速时，只需要将车辆间距与标定的车辆间距进行对比，并同比例放大或缩小标定距离对应的防炫目区域，即可得到当前防炫目区域的范围。
防炫目区域还可以根据主车辆摄像头中目标车辆对应的像素点和主车辆车灯控制像素点的对应关系来确定，具体来说，主车辆和目标车辆之间的距离与主车辆摄像头中像素点存在一个对应关系，当车辆距离较近时，主车辆摄像头中像素点较多，而当车辆距离拉远时，主车辆摄像头中的像素点会减小，如图15(a)为不同车距摄像头中目标车辆对应的像素点的范围示意图，图15(b)为不同车距车灯控制像素点的范围示意图，将不同车距主车辆摄像头中目标车辆的像素点及对应的不同车距车灯控制像素点进行标定，进而可以根据车辆距离得到防炫目区域。
进一步的，如果目标车辆为超车行驶，则当目标车辆进入主车辆的大灯的照射区域时，对目标车辆的目标侧窗和目标外后视镜进行防炫目，其中，目标车辆的目标侧窗和目标外后视镜为临近所述主车辆一侧的所述目标车辆的侧窗和外后视镜；当目标车辆的后风挡玻璃进入主车辆的大灯的照射区域时，对目标车辆的目标侧窗和目标外后视镜进行防炫目，同时，对目标车辆的后风挡玻璃进行防炫目，进一步根据目标车辆与所述主车辆的相对位置调整所述防炫目区域的范围。
在具体的示例中，可以通过算法对目标车辆的车头以及前轮进行识别，防炫目区域为车头到车灯的边界，如图16所示，具体来说，目标车辆刚进入车灯照明区域，同时车头和 车轮进入传感器识别区域时，采取车轮上部分防炫目的方式，防炫目区域从车头到车灯的边界，当车辆继续行驶，防炫目区域继续延伸，直到后风挡玻璃出现在传感器识别区域，采取后风挡玻璃和侧窗防炫目的方式进行控制，即对目标车辆的目标侧窗和目标外后视镜进行防炫目，同时，对后风挡玻璃进行防炫目，需要说明的是，实际防炫目区域非区块增加而是线性连续增加的效果。
另外，考虑到传感器区域和车灯照射区域之间存在“盲区”，可以通过盲区监测系统检测是否有车靠近，盲区监测系统通过在汽车后保检杠内安装两个24GHz雷达传感器，在车辆行驶速度大于10km/h自动启动，实时向左右3米后方8米范围，发出探测微波信号，系统对反射回的微波信号进行分析处理，即可知后方目标车辆与主车辆的距离，速度和运动方向等信息，通过系统算法，排除固定物体和远离的物体，当探测到盲区内有车辆靠近时，指示灯闪烁，主车辆的车灯获取盲区有车辆靠近的结果信息，通过结果信息，判定目标车辆是左侧车道还是右侧车道车辆，一方面可以通过投影相应标识，提醒驾驶员，一方面开启相应的防炫目区域，开启区域如图16所示，即将传感器不能识别区域角度到车灯照射角度间这部分照明关闭或变弱，具体角度通过实际标定确认。
进一步的，如果目标车辆为变道行驶，则追踪目标车辆的目标侧窗和目标外后视镜，其中，目标车辆的目标侧窗和目标外后视镜为临近所述主车辆一侧的目标车辆的侧窗和外后视镜；对目标车辆的目标侧窗和目标外后视镜进行防炫目，同时，对目标车辆的后风挡玻璃进行防炫目。
如图17(a)所示，为目标车辆同向变道时的防炫目区域变化示意图，目标车辆从左到右的防炫目区域依次为：右侧车窗和右侧外后视镜以及后风挡玻璃—后风挡玻璃和外后视镜—左侧车窗和左侧外后视镜以及后风挡玻璃。
如图17(b)所示，为目标车辆对向变道时的防炫目区域变化示意图，目标车辆的防炫目区域为靠近主车辆一侧的侧窗和外后视镜以及前风挡玻璃。
根据本发明实施例的车辆的防炫目控制方法，可以通过目标车辆的图像确定目标车辆的行驶方向和与主车辆的相对位置，进而根据目标车辆的行驶方向和与主车辆的相对位置实时调整车辆大灯照射至目标车辆的防炫目区域，即主车辆根据目标车辆的不同姿态实时地调整主车辆的大灯以实现防炫目效果，从而提高车辆在行驶过程中的安全性。
图7是根据本发明一个实施例的车辆的防炫目控制系统的结构框图。如图7所示，根据本发明一个实施例的车辆的防炫目控制系统700，包括：获取模块710和控制模块720。

根据本发明实施例的车辆的防炫目控制系统，可以在其他车辆的行驶姿态发生变化时(如进入弯道、过十字路口、掉头)，均能够时刻对其起到防炫目效果，从而，避免因车辆远光灯炫目而造成交通事故，提高车辆在行驶过程中的安全性。
