本申请实施例中目标车辆通过激光雷达获取到周围环境的点云后，将点云输入预先训练好的分类模型中以获得点云中各个对象的分类结果。其中，第一对象可以是分类结果为车辆的对象，非第一对象可以是分类结果为车辆以外的对象，和/或无分类结果的对象，在实际应用中，第一对象还可以是分类模型能够准确进行分类的对象而不仅仅限于车辆。示例性地，目标车辆周围有其他车辆、行人、自行车、骑着自行车的人、雪糕筒等，则对于车辆、行人、自行车和雪糕筒等分类模型可以给出明确的分类结果，而对于骑着自行车的人的分类属于自行车还是属于行人则无法确定，而且在可视化界面中，目标车辆周围的其他车辆对自动驾驶更具有参考意义，可以在可视化界面中将车辆作为第一对象并显示能够体现车辆大小的第一对象模型，对于非第一对象，可以在可视化界面上显示第二对象模型以表达目标车辆检测到非第一对象。
其中，第一对象模型可以为目标车辆检测到的其他车辆的三维模型，该三维模型可以是其他车辆的实体模型，可选地，第一对象模型是边框模型，边框模型可以是三维矩形框，第二对象模型可以为点云模型，即对于第一对象，在地图上显示与第一对象匹配的三维矩形框，对于非第一对象，在地图上显示非第一对象的点云，第二对象模型还可以是至少包含点云的模型，即第二对象模型可以为点云和实体模型的混合模型，由于在地图上直接以点云形态或者至少部分为点云形态来呈现非第一对象，无需根据数据来模拟非第一对象的模型，即减少了非第一对象模型渲染的数据量，甚至无需为非第一对象渲染模型，提高了模型渲染速度。
本申请实施例在目标车辆执行行驶任务时，在地图上为目标车辆所检测到 的第一对象显示第一对象模型，为目标车辆所检测到的非第一对象显示第二对象模型，解决了分类模型对非第一对象分类不准确或者无法分类，造成在可视化界面为非第一对象显示错误的模型甚至不显示任何模型问题，能够为目标车辆所检测到的、分类准确的第一对象显示第一对象模型，分类不准确或者无法分类的非第一对象显示至少包含点云数据的第二对象模型，既可以为目标车辆检测到的第一对象和非第一对象显示模型，又无需对非第一对象进行分类，而是为非第一对象显示至少包含点云的第二对象模型，减少了非第一对象模型渲染的数据量，甚至无需为非第一对象渲染模型，实现了在为检测到的对象显示模型的同时又提高了模型渲染的速度，提高了用户体验。

S204、获取所述目标车辆在执行所述行驶任务时所检测到的环境信息。
具体地，目标车辆上可以安装有激光雷达、毫米波雷达、相机、红外传感器等传感器，目标车辆在行驶过程中可以通过以上至少一种传感器检测目标车辆的周围环境获得多种传感数据作为环境信息。示例性地，目标车辆上安装有至少一个激光雷达，目标车辆在执行行驶任务过程中，安装在目标车辆上的激光雷达发射激光信号，该激光信号被目标车辆周围场景中的各种对象漫反射后返回该激光雷达，激光雷达对接收到的激光信号进行降噪、采样等处理后获得点云作为环境信息。
目标车辆还可以通过相机按照预设周期拍摄图像，进一步根据拍摄到的图像结合图像测距算法计算图像中的各个对象到目标车辆的距离作为环境信息，或者对图像进行语义分割获得图像中的语义信息作为环境信息，例如，对图像进行语义分割获得红绿灯、车辆、行人等语义分割区域作为环境信息。其中，相机可以为单目相机、双目相机、多目相机中的一种。
S205、识别所述环境信息中所述第一对象的位置和类型。
在本申请实施例中，环境信息可以包括通过传感器获得的点云，可以预先训练分类模型来对形成点云的各种对象进行分类，例如，可以获取各种对象的点云，并标注对象所属的分类后作为训练数据来训练分类模型，训练好的分类模型在输入点云后可以从点云中识别各个对象所属的分类。
当然，环境信息还可以是相机拍摄的图像，可以获取各种对象的图像，并标注对象所属的分类后作为训练数据来训练分类模型，训练好的分类模型在输入图像后可以从图像中识别各个对象所属的分类，或者环境信息可以是毫米波雷达的雷达数据，可以采用雷达数据来训练分类模型，可选地，环境信息数据可以包括点云、图像、雷达数据等多种传感数据，可以采用多种传感数据来训练分类模型，本申请实施例对采用何种数据来训练分类模型不加以限制。
本申请实施例中，对象可以为目标车辆周围的物体，例如，对象可以是目标车辆周围的其他车辆、行人、自行车、交通灯、雪糕筒等。可选地，第一对象可以为车辆，当环境信息为点云时，可以将点云输入预先训练的分类模型中识别出类型为车辆的对象作为第一对象，同时可以通过点云配准获得点云中第一对象的位置，该位置可以是第一对象相对于目标车辆的位置，也可以是第一对象在世界坐标系中的位置，其中，第一对象的数量可以是一个或者一个以上，即从点云中识别出目标车辆周围的所有车辆，并确定各个车辆的位置。
S206、根据所述第一对象的类型获取适配的第一对象模型。
本申请的可选实施例中可以预先为第一对象设置第一对象模型，该第一对象模型可以是第一对象的三维模型，还可以是表示第一对象外形尺寸的边框模型。如图3所示，第一对象的模型为边框模型20。在实际应用中，可以通过点云确定第一对象的外形尺寸，例如确定第一对象的长、宽、高尺寸，然后根据第一对象的长、宽、高尺寸从边框模型库中查找适配尺寸的边框模型作为第一对象的第一对象模型，从而可以为不同尺寸大小的第一对象显示适配尺寸大小的第一对象模型。进一步地，可以按照外形尺寸将第一对象分为大型车辆和小型车辆，大型车辆可以包括货车、公共汽车或者其他体积较大的工程车辆，小型车量可以包括小型客车、面包车等，从而可以按照第一对象的外形尺寸确定第一对象模型所属的车辆类型，使得用户可以了解目标车辆周围的车辆类型以决定是否进行人工干预，例如，当在港口或工业区存在货车较多的路况时，用户可以从可视化界面得知目标车辆行驶于货车较多的路况，从而可以决定是否从自动驾驶模式转换为远程控制驾驶模式。
在本申请的另一可选实施例中，可以将目标车辆上的传感器检测到的环境信息输入预先训练好的检测模型中，通过该检测模型获得各个对象的分类结果、位置、外形尺寸、朝向、速度和加速度等，当对象的分类结果为车辆时，该对象为第一对象，将第一对象的外形尺寸数据输入渲染器中渲染出边框模型做为第一对象模型，通过外形尺寸渲染边框模型，数据量少，模型简单，可以提高获取第一对象模型的速度。
S207、根据所述第一对象的位置显示所述第一对象模型。
具体地，在地图上第一对象所在的位置显示第一对象模型，从而在可视化界面上显示目标车辆的车辆模型，以及显示车辆模型周围的第一对象的第一对象模型，示例性地，在确定第一对象模型的朝向，例如确定车头的方向后，可以按照该朝向在第一对象所在的位置显示第一对象模型，即从第一对象模型上可以反映车辆的车头的朝向，从而可以在可视化界面上能够清楚地了解到车辆是同向行驶车辆还是对向行驶车辆，具体地，可以在边框模型中车头所在一端 增加车头的形状特征或者标记，在边框模型中车尾所在一端增加车尾的形状特征或者标记等。如图3所示，在地图上显示目标车辆的车辆模型10、显示车辆模型10周围的第一对象的第一对象模型20。
S208、识别所述环境信息中所述第二对象的位置和类型。
在本申请实施例中，第二对象可以是第一对象以外的对象，可选地，第一对象是车辆，第二对象是车辆以外的行人、自行车、电线杆、雪糕筒等。其中，环境信息可以包括点云，可以将点云输入预先训练好的分类模型中，以识别出类型不是第一对象所属的类型或者无法分类的对象，将类型不是第一对象所属的类型或者包含无法分类的对象作为第二对象，即非第一对象，并通过点云配准获得点云中第二对象的位置，当然，环境信息还可以包括相机拍摄的图像、毫米波雷达的扫描数据等，可以将环境信息输入预先训练的检测模型中获得各种对象的分类结果和位置，可以将与第一对象不同分类的对象作为第二对象。
S209、从所述环境信息中提取所述第二对象的点云。
本申请的一个实施例中，环境信息包括激光雷达获得的点云和相机拍摄的图像，可以采用目标检测算法识别图像中的第二对象，在将相机和激光雷达进行联合标定后，将图像中识别出的第二对象投射到点云中，从而可以从激光雷达获得的点云中分离出第二对象的点云。
在本申请的另一实施例中，目标车辆上的传感器(相机、激光雷达、毫米波雷达等)按照预设周期获取到多帧环境信息，将每个周期获取到的环境信息按照时间顺序存储至队列中，从队列中读取每帧环境信息输入分类模型中以从每帧环境信息中识别出至少一个第二对象，并通过帧环境信息提取出所有第二对象的点云，然后将所有第二对象的点云输入预先训练的点云分离模型中以分离出每个第二对象的点云，并对多帧环境信息获得的每个第二对象的点云进行平滑处理，将平滑处理后的点云作为第二对象的最终点云。其中，点云分离模型可以通过获取多个第二对象的点云来训练，使得点云分离模型可以从多个对象的点云中分离出每个对象的点云。
在本申请实施例中，对点云进行平滑处理可以包括点云预处理和点云平滑，其中，点云预处理可以是去掉离群点、去掉噪声点和去掉失真点等，平滑处理可以包括均值滤波平滑，具体地，对于每个第二对象的点云中的每个点，可以计算多帧环境信息获得的每个第二对象的点云中该点的平均值，例如，计算相邻两帧或者两帧以上环境信息获得的每个第二对象的点云中某个点的三维坐标的平均值作为平滑处理的结果。当然，平滑处理还可以是中值滤波平滑、高斯滤波平滑等，本申请实施例对点云的平滑处理方式不加以限制。
本申请实施例先对第二对象的点云进行预处理，可以去除无效点和噪声点，提高点云的准确度，更进一步地，对第二对象的点云进行平滑处理，可以获得第二对象的平滑点云，在显示第二对象的点云时，能够在可视化界面取得良好的显示效果。
S210、根据所述第二对象的位置显示至少包含所述点云的第二对象模型。
在本申请实施例中，第二对象模型可以是点云模型，即直接在地图上第二对象所在的位置显示第二对象的点云模型，如图3所示，在图3中显示点云模型70。本申请实施例无需为第二对象进行明确分类，也无需为第二对象匹配模型，提高了第二对象的模型的显示效率。
在本申请的可选实施例中，可以获取为第二对象预先设置的显示模板，该显示模板可以包括一实体的修饰模型，将第二对象的点云显示于该修饰模型上，其中，将第二对象的点云显示于该修饰模型上包括：将第二对象的点云进行缩放，以使得第二对象的点云在地面上的投轮廓被修饰模型的投影轮廓所包围。示例性地，修饰模型为一圆盘，第二对象为雪糕筒，可以将雪糕筒对应的点云缩放，将缩放后的点云显示在圆盘上。
在另一个示例中，将第二对象的点云显示于该修饰模型上包括：计算点云的外形轮廓尺寸，根据所述外形轮廓尺寸调整修饰模型的尺寸，将在调整后的修饰模型中显示点云。示例性地，修饰模型可以是一圆柱空间，该圆柱空间底部为实体，上部空间为透明的，则可以根据点云在地面上的投影轮廓调整圆柱空间的直径以及通过点云的高度调整圆柱空间的高，使得点云可以容纳在该圆柱空间中，例如在一圆柱空间的底部的实体上显示行人的点云，从而可以从可视化界面根据该圆柱空间的轮廓了解到行人的外形尺寸大小。
本申请实施例在目标车辆执行行驶任务时，根据目标车辆的实时位置显示预设范围内地图并在地图上显示目标车辆的车辆模型，在获取环境信息后，从环境信息中识别第一对象的位置和类型，根据第一对象的类型匹配第一对象模型显示在地图上，从环境信息中识别第二对象的位置和类型，并提取第二对象的点云，在地图上显示第二对象的包含点云的第二对象模型，解决了分类模型对非第一对象分类不准确或者无法分类，造成在可视化界面为非第一对象显示错误的模型甚至不显示任何模型问题，能够为目标车辆所检测到的、分类准确的第一对象显示第一对象模型，分类不准确或者无法分类的第二对象显示包含点云的第二对象模型，既可以为目标车辆检测到的第一对象和第二对象显示模型，又无需对第二对象进行分类，而是为非第一对象显示至少包含点云的第二对象模型，减少了非第一对象模型渲染的数据量，甚至无需为非第一对象渲染模型，提高了模型渲染的速度，进而提高了用户体验。
实施例三
图4为本申请实施例三提供的一种可视化界面的显示方法的流程图，本实施例以前述实施例一为基础进行优化，该方法具体包括如下步骤：
S301、确定目标车辆执行行驶任务。
S302、根据所述目标车辆实时位置显示预设范围内地图。
S303、在所述地图上显示对象模型，其中，为所述目标车辆所检测到的第一对象显示第一对象模型，为所述目标车辆所检测到的非第一对象显示至少包括点云数据的第二对象模型。
S304、显示所述目标车辆执行所述行驶任务的任务进度信息，其中，所述任务进度信息包括进度条、已行驶的距离、已行驶的时间中的至少一者。
本申请实施例中，任务进度信息可以是目标车辆执行行驶任务的进度信息，任务进度信息可以是进度条、已行驶的距离、已行驶的时间中的至少一项。其中，进度条可以根据已行驶距离和总距离来生成，已行驶的距离可以通过目标车辆上的里程计来统计。
如图3所示，在可视化界面显示任务进度信息30，在任务进度信息30中，可以包括进度条，该进度条表达了行驶任务的执行进度，还可以包括已行驶距离，即目标车辆开始执行行驶任务后所行驶的距离，还可以包括已行驶时间，即目标车辆开始执行行驶任务后所行驶的总时间，当然，任务进度信息还可以采用百分比等其他形式来表示，本申请实施例对任务进度信息的显示方式不加以限制。
S305、在所述地图上显示为所述目标车辆生成的行驶路线。
具体地，行驶任务可以为目标车辆从指定起点行驶到指定终点的任务，在确定起点和终点后，结合目标车辆上的传感器所检测到的环境信息实时规划行驶路线并将行驶路线显示在地图上，示例性地，在确定起点和终点后规划出从起点行驶到终点的行驶路线，在实时行驶的过程中，根据传感器所检测到的环境信息实时规划行驶过程中目标车辆所行驶的车道。如图3所示，可以在目标车辆的行驶方向上以光带的形式显示行驶路线50，从而使得行驶路线50与地图中的斑马线、车道线等道路标记线明显区分，有利于用户从地图上分辨出行驶路线。
S306、当所述第一对象模型在所述行驶路线上时，高亮显示所述第一对象模型。
在本申请实施例中，第一对象可以为目标车辆所检测到的车辆，可以根据 第一对象对目标车辆行驶的干扰度确定是否高亮该第一对象的第一对象模型。
在本申请的一个示例中，目标车辆直线行驶时，目标车辆所检测到的车辆可以是目标车辆周围的车辆，干扰度可以是目标车辆周围预设范围内所检测的车辆。可选地，目标车辆检测以目标车辆为中心的、预设半径的圆形区域内的车辆，获得该圆形区域内所有车辆与目标车辆的距离，当该距离小于预设阈值时，确定该车辆为干扰车辆，可以高亮显示该圆形区域内的干扰车辆的模型，即高亮显示第一对象模型，例如，当目标车辆做直线行驶时，目标车辆前方的车辆急刹车或者行驶速度下降造成前方车辆与目标车辆的距离减小，当该距离小于预设阈值时，表明前方车辆在目标车辆所需行驶的行驶路线上并且距离小于预设阈值，可以高亮显示行驶路线上前方车辆的第一对象模型以警示用户该车辆干扰了目标车辆行驶。
又例如，当目标车辆做直线行驶时，目标车辆旁边的车辆变道接近目标车辆，当旁边的车辆与目标车辆的距离小于预设阈值时，如果目标车辆仍然以目前方向行驶，有可能发生碰撞，则可以高亮显示目标车辆旁边的车辆的第一对象模型，以警示旁边车辆干扰了目标车辆的正常行驶。本申请实施例能够高亮显示以目标车辆为中心的、预设半径的圆形区域内的干扰车辆，以利于用户及时进行人工监督或者人工干预，提高目标车辆驾驶的安全性。
在本申请的另一示例中，当目标车辆变道时，可以计算目标车辆周围的车辆到目标车辆的距离，如果该距离小于预设阈值，则高亮周围车辆中与目标车辆的距离小于预设阈值的车辆的第一对象模型，以警示周围有车辆干扰到目标车辆变道，以利于用户及时进行人工监督或者人工干预，提高目标车辆驾驶的安全性。
进一步地，可以根据干扰度的大小确定高亮显示第一对象模型的亮度，例如，根据距离对高亮显示的颜色进行渐变，示例性地，高亮颜色为红色，距离越小，红色的颜色越深，反之越小，使得用户可以从高亮的颜色的亮度获知周围车辆对目标车辆的干扰度。
S307、显示红绿灯信息，所述红绿灯信息用于表示所述目标车辆所检测到的红绿灯的状态。
具体地，目标车辆上安装有相机，可以通过相机对目标车辆需要经过的路口的红绿灯进行拍摄获得图像，对该图像进行图像识别获取到红绿灯的状态，并将红绿灯状态显示在可视化界面的虚拟红绿灯中。如图3所示，可在可视化界面的右上角显示红绿灯信息60。
在本申请的可选实施例中，如果相机拍摄到多个红绿灯，例如，在十字路 口拍摄到多个红绿灯时，可以根据目标车辆的位置和行驶路线从多个红绿灯中确定出目标红绿灯并显示目标红绿灯的状态，示例性地，当目标车辆的下一行驶路径为从当前位置继续直线行驶时，将目标车辆前方的红绿灯作为目标红绿灯，并识别目标红绿灯的状态显示在可视化界面上，又或者目标车辆的下一行驶路径为转向行驶时，将目标车辆转向方向的红绿灯作为目标红绿灯，并识别目标红绿灯的状态显示在可视化界面上。本申请实施例从多个红绿灯中确定目标红绿灯，可以避免对多个红绿灯的状态进行识别，减少了图像识别的数据量，既提高了红绿灯信息的显示速度，又减少了在可视化界面显示红绿灯的数量，使得可视化界面更为简洁。
在本申请的另一可选实施例中，可以先确定人行红绿灯的状态，通过人行红绿灯的状态确定目标车辆前方的红绿灯的状态，具体地，当从地图上检测到目标车辆行驶方向上有斑马线时，确定斑马线两端的人行红绿灯，并获取该人行红绿灯的图像，对该图像进行识别获得人行红绿灯状态，根据该人行红绿灯状态确定目标车辆前方用于指示目标车辆行驶的红绿灯状态，示例性地，当人行红绿灯为绿色时，确定目标车辆前方用于指示目标车辆行驶的红绿灯状态为红色，当人行红绿灯为红色时，确定目标车辆前方用于指示目标车辆行驶的红绿灯状态为绿色，由此可以提前显示红绿灯信息，或者前方车辆遮挡前方红绿灯导致相机无法获得前方红绿灯图像时，通过旁边的人行红绿灯信息确定前方红绿灯信息。
S308、显示为所述目标车辆生成的导航信息。
本申请实施例中，导航信息可以是目标车辆的行驶速度、目标车辆到目的地的距离，行驶路线的转向提醒信息、行驶过程中的车辆变道提醒信息等，可以将导航信息显示在可视化界面中。其中，转向提醒信息可以是在可视化界面中显示转向标记以及目标车辆到转向位置的距离，行驶速度可以是在可视化界面显示文字或者虚拟速度表，车辆变道提醒信息可以通过扬声器以语音方式进行播报。如图3所示，导航信息40为行驶路线的转向提醒信息和目标车辆的行驶速度。
在本申请实施例中，目标车辆上的传感器还可以感知周围环境的光强度，根据光强度调整可视化界面的显示模式，显示模式可以包括黑夜模式或者白天模式，当然，还可以根据当前时间确定当前是白天还是黑夜，以实现显示模式在黑夜模式和白天模式之间切换，以使得可视化界面能够根据环境的光强度来进行显示，提高人眼观看的舒适度。
本申请实施例在目标车辆执行行驶任务时，在地图上为目标车辆所检测到的第一对象显示第一对象模型，为目标车辆所检测到的非第一对象显示至少包 含点云数据的第二对象模型，解决了分类模型对非第一对象分类不准确或者无法分类，造成在可视化界面为非第一对象显示错误的模型甚至不显示任何模型问题，能够为目标车辆所检测到的、分类准确的第一对象显示第一对象模型，分类不准确或者无法分类的非第一对象显示第二对象模型，既可以为目标车辆检测到的第一对象和非第一对象显示模型，又无需对非第一对象进行分类，而是为非第一对象显示至少包含点云的第二对象模型，减少了非第一对象模型渲染的数据量，甚至无需为非第一对象渲染模型，实现了在为检测到的对象显示模型的同时又提高了模型渲染的速度，提高了用户体验。
进一步地，在可视化界面上为目标车辆显示行驶路线、红绿灯信息和导航信息，实现了行驶数据的可视化。
更进一步地，当预设范围内所检测到的第一对象干扰目标车辆行驶时，高亮显示第一对象的第一对象模型，以警示用户该第一对象挡住了目标车辆行驶，以利于用户及时进行人工监督或者人工干预，提高目标车辆驾驶的安全性。
