Description

确定检测对象的三维信息的方法及装置
本申请要求于2020年08月11日提交国家知识产权局、申请号为202010803409.2、申请名称为“确定检测对象的三维信息的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及智能驾驶领域，尤其涉及一种确定检测对象的三维信息的方法及装置。
背景技术
在智能驾驶场景中，行驶的车辆(在本申请中记为第一车辆)需要实时的检测周围其他车辆(在本申请中记为第二车辆)的相对于第一车辆的位置，第二车辆的大小(车辆的长度、车辆的宽度)以及第二车辆的方向(车辆朝向，行驶方向等)，以便于第一车辆根据这些信息规划自身的行驶路线，对其他车辆可能带来的危害行为进行预判和规避。
第一车辆确定第二车辆的大小，方向以及相对于第一车辆的位置时，需要确定第二车辆的三维(3D)信息。当前第一车辆可以通过双目3D的方式，确定第二车辆的3D信息。但是双目3D的方式需要搭配双目摄像头，价格昂贵；并且目前的对于第二车辆3D信息确定过程中所使用的算法需要较高的图像标注成本，以及计算量。
发明内容
本申请提供一种确定检测对象的三维信息的方法及装置，解决了现有技术中确定周围车辆的三维信息时，对硬件要求高，计算数据量大的问题。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种确定检测对象的三维信息的方法，包括：第一车辆获取待检测图像；待检测图像包括第一检测对象；第一车辆确定第一检测对象的可通行区域边界，以及第一检测对象的触地线；可通行区域边界包括第一检测对象在待检测图像中的边界；触地线为第一检测对象与地面的交点的连线；第一车辆根据可通行区域边界，以及触地线，确定第一检测对象的三维信息。
基于上述技术方案，本申请提供的确定检测对象的三维信息的方法，第一车辆能够根据采集到的待检测图像，确定第一检测对象的可通行区域边界以及触地线，进一步的，第一车辆根据第一检测对象的可通行区域边界，以及触地线，确定第一检测对象在二维图像中表征出的三维信息。
上述待检测图像可以为单目摄像头采集的二维图像。这样，第一车辆通过单目摄像头采集第一检测对象的图像信息即可确定第一检测对象的三维信息。相比较于现有技术中第一车辆需要依赖双目摄像头采集第一检测对象的图像信息以确定第一检测对象的三维信息的方法，本申请中第一车辆采用单目摄像头采集第一检测对象的图像信息确定第一检测对象的三维信息，能够大大降低确定第一检测对象的三维信息的硬件成本。
此外，本申请提供的确定检测对象的三维信息的方法，第一车辆只需标记第一检测对象的可通行区域边界，并根据第一检测对象的可通行区域边界确定第一检测对象的触地线。第一车辆可以根据第一检测对象的可通行区域边界，以及触地线，结合第一检测对象在待检测图像中的视觉关系等，确定第一检测对象在二维图像中表征出的三维信息。因此，本申请提供的确定检测对象的三维信息的方法，无需第一车辆进行其他额外的数据标注训练，从而降低了确定第一检测对象的三维信息的计算量，以及降低了确定第一检测对象的三维信息占用的图形处理器(Graphics Processing Unit，GPU)资源。
结合第一方面，在一种可能的实现方式中，第一检测对象的三维信息用于确定第一检测对象的大小、方向，以及相对位置中的至少一项。
例如，第一车辆可以将第一检测对象在待检测图像中表征出的三维信息，转换到第一车辆的车体坐标系中，确定第一检测对象在第一车辆的车体坐标系中对应的大小，方向，以及第一检测对象相对于第一车辆的位置。这样，第一车辆可以结合周围多个第一检测对象在第一车辆的车体坐标系中对应的大小，方向，以及第一检测对象相对于第一车辆的位置，规划第一车辆的行车路线，实现第一车辆的智能驾驶。
结合第一方面，在一种可能的实现方式中，第一检测对象的可通行区域边界包括多个与第一标识对应的边界点，以及与多个第二标识对应的边界点；第一标识还对应于第一检测对象的第一侧面，第二标识还对应于第一检测对象的第二侧面；第一侧面和第二侧面为第一检测对象中两个相交的侧面。
基于此，在第一车辆采用单目摄像头采集第一检测对象的两个侧面(即待检测图像中包括第一检测对象的两个侧面)的情况下，第一车辆可以分别对每个侧面的可通行区域边界进行标记，并为不同的侧面的可通行区域边界分配不同的标识，第一车辆可以根据不同的标识确定各个侧面对应的可通行区域边界。
结合第一方面，在一种可能的实现方式中，触地线中包括第一触地线和第二触地线；第一触地线为拟合多个与第一标识对应的边界点确定的触地线；第二触地线为拟合多个与第二标识对应的边界点确定的触地线。
基于此，第一车辆根据每个侧面对应的可通行区域边界，确定第一检测对象在待检测图像中示出的每个侧面对应的触地线。由于触地线是根据每个侧面对应的可通行区域边界上的点拟合得到的，因此每个侧面对应的触地线能够表征该侧面在地面投影的部分边界(即每个面在地面投影的最外沿部分)。
结合第一方面，在一种可能的实现方式中，多个与第一标识对应的边界点中包括第一边界点；第一边界点为多个具有第一标识的边界点中，与第二触地线的距离最大的边界点；多个与第二标识对应的边界点中包括第二边界点；第二边界点为多个具有第二标识的边界点中，与第一触地线的距离最大的边界点。
基于此，上述第一边界点能够表征第一检测对象的第一侧面中与第一车辆的距离最大的点，也即是说，第一边界点能够表征第一侧面距离第一车辆最远的顶点。第二边界点能够表征第一检测对象的第二侧面中，与第一车辆的距离最大的点，也即是说，第二边界点能够表征第二侧面距离第一车辆最远的顶点。
结合第一方面，在一种可能的实现方式中，第一检测对象的三维信息根据第一检 测对象对应的三个点和两条线确定；其中，三个点中的第一个点为第一边界点在地面上的投影；三个点中的第二个点为第二边界点在地面上的投影；三个点中的第三个点过第二个点，且与第二触地线平行的直线与第一触地线的交点；两条线中的第一条线为第一个点和第三个点之间的连线；两条线中的第二条线为第二个点和第三个点之间的连线。

基于上述技术方案，第一边界点在地面上的投影能够表征第一侧面在地面上的投影与第一车辆的距离最远的点，第二边界点在地面上的投影能够表征第二侧面在地面上的投影与第二车辆的距离最远的点，第三个点能够表征第一侧面在地面投影与第二侧面在地面投影的交点。第一触地线能够表征第一侧面在地面投影的方向。第二触地线能够表征第二侧面在地面投影的方向。因此，第一车辆可以确定第一条线为第一侧面在地面投影的最外侧框线，第二条线为第二侧面在地面投影的最外侧框线。
进一步的，第一车辆可以根据第一条线和/或第二条线的方向，以及第一条线和第二条线在待检测图像中的位置，确定第一检测对象的方向。第一车辆可以根据第一条线的长度和第二条线的长度，以及第一条线和第二条线在待检测图像中的位置，确定第一检测对象的大小，第一车辆可以根据第一条线和第二条线在待检测图像中的位置，确定第一检测对象相对于第一车辆的位置。
这样，第一车辆仅需根据第一检测对象的可通行区域边界，以及触地线，对第一检测对象上特定的点进行投影，即可确定第一检测对象的三维信息，大大降低了第一车辆确定第一检测对象的三维信息的计算量。
结合第一方面，在一种可能的实现方式中，第一车辆根据第一边界点，以及第一触地线，确定第一个点；第一车辆根据第一触地线，第二触地线，以及第二边界点，确定第二个点；根据第一触地线，第二触地线，以及第二个点，确定第三个点。

结合第一方面，在一种可能的实现方式中，第一车辆确定第一直线；第一直线为在待检测图像中过第一边界点，且与视平线垂直的直线；第一车辆确定第一直线与第一触地线的交点为第一个点。
基于此，第一车辆可以根据第一触地线和第一边界点在待检测图像中的视觉关系，快速准确的确定第一边界点在地面的投影。第一车辆通过该方式确定第一边界点在地面的投影可以进一步降低第一车辆确定第一检测对象的三维信息的计算量。
结合第一方面，在一种可能的实现方式中，第一车辆确定第二直线和第三直线；其中，第二直线为在待检测图像中，过第一触地线与视平线的交点，以及第二触地线 中远离第一触地线的端点的直线；第三直线为在待检测图像中过第二边界点，且垂直于视平线的直线；第一车辆确定第二直线和第三直线的交点为第二个点。

基于此，第一车辆可以根据该侧面的可通行区域边界，确定该侧面的触地线。由于该触地线是根据该侧面对应的可通行区域边界上的点拟合得到的，因此该触地线能够表征该侧面在地面投影的部分边界(即每个面在地面投影的最外沿部分)。
结合第一方面，在一种可能的实现方式中，多个具有第三标识的边界点中包括第三边界点和第四边界点；第三边界点为多个具有第三标识的边界点中，距离第三触地线的一端最远的点；第四边界点为多个具有第三标识的边界点中，距离第三触地线的另一端最远的点。

以上为对本申请实施例记载的确定检测对象的三维信息的方法的应用场景进行了简要介绍。
为了使得本申请更加的清楚，以下将对本申请涉及到的部分概念做简单介绍。
1、触地线
触地线是指待检测图像中的检测对象与地面实际接触的点组成的线段。
以检测对象为车辆为例，车辆的触地线为车辆轮胎与地面接触点的连线。车辆的触地线可以按照车的四个侧面(分别为左侧面、右侧面、前侧面和后侧面)进行区分。车辆的一个侧面对应一条触地线。
具体来说，以常见的家用轿车为例，车辆左前方轮胎与地面的接触点，记为接触点1；车辆右前方轮胎与地面的接触点，记为接触点2；车辆左后方轮胎与地面的接触点，记为接触点3；车辆右后方轮胎与地面的接触点，记为接触点4。
车辆的左侧面对应的触地线，为接触点1和接触点3之间的连线。
车辆的右侧面对应的触地线，为接触点2和接触点4之间的连线。
车辆的前侧面对应的触地线，为接触点1和接触点2之间的连线。
车辆的后侧面对应的触地线，为接触点3和接触点4之间的连线。
需要指出的是，车辆的轮胎与地面接触部分，通常为一个接触面(该接触面可以近似的认为是一个长方形)。本申请中可以将车辆左前方轮胎与地面的接触面的左前方的顶点，作为接触点1；将车辆右前方轮胎与地面的接触面的右前方的顶点，作为接触点2；将车辆左后方轮胎与地面的接触面的左后方的顶点，作为接触点3；将车辆右后方轮胎与地面的接触面的右后方的顶点最为接触点4。
2、神经网络模型
神经网络模型是由大量处理单元(记为神经元)互相连联组成的信息处理系统，神经网络模型中的神经元中包含有相应的数学表达式。数据输入神经元之后，神经元运行其包含的数学表达式，对输入数据进行计算，生成输出数据。其中，每个神经元的输入数据为与其连接的上一个神经元的输出数据；每个神经元的输出数据为与其连接的下一个神经元的输入数据。
在神经网络模型中，输入数据之后，神经网络模型根据自身的学习训练，为输入数据选择相应的神经元，并根据这些神经对对输入数据进行计算，确定并输出最终的运算结果。同时，神经网络在数据运算过程中还可以不断学习进化，根据对运算结果的反馈不断优化自身的运算过程，神经网络模型运算训练次数越多，得到的结果反馈越多，计算的结果越准确。
本申请实施例中所记载的神经网络模型用于对图像采集装置采集到的图片进行处理，确定图像中位于各个检测对象上的可通行区域边界(记为检测对象的可通行区域边界)。
3、可通行区域(freespace)
可通行区域是指汽车可以行驶通过的区域。例如，第一车辆检测到的前方区域中行人，障碍物，以及其他车辆之间的空旷区域，记为第一车辆的可通行区域。
可通行区域一般位于检测对象的边界上，因此在本申请实施例中，可以用位于检测对象的边界上的可通行区域表征第一检测对象的边界，进而根据位于第一检测对象上的可通行区域，确定第一检测对象的三维信息。
在本申请实施例中，神经网络模型输出的检测对象的可通行区域边界通常以多个具有相应标识的点示出。例如，第二车辆左侧的可通行区域包括位于车辆左侧的边界点上的多个点。该多个点用于表征第二车辆左侧的可通行区域。
此外，神经网络模型输出的这些点中，位于检测对象的不同侧面的点可以具有不同的标识，例如，这些标识可以包括：标识“00”，用于表征位于检测对象左侧可通行区域边界上的点；标识“01”，用于表征位于检测对象右侧可通行区域边界上的点的标识；标识“10”，用于表征位于检测对象前侧可通行区域边界上的点的标识；标识“11”，用于表征位于车辆后侧可通行区域边界上的点的标识。
4、视平线
视平线是指图像中与视线平行的直线。在本申请实施例中，视平线指的是图像中与图像采集设备高度相同，且平行于图像采集设备的直线。
5、灭点(vanishing point)
根据图像的透视原理，水平面上相互平行的两条直线，在二维的图像中会于视平线处相交于一点，该交点即为灭点。
6、车体坐标系
车体坐标系指的是坐标系原点位于车身上的三维坐标系。一般来说，车体坐标系的原点与车辆的质心重合，X轴沿车辆的长度方向，指向车辆正前方，Y轴沿车辆宽度方向指向驾驶员左侧的方向，Z轴沿车辆高度方向指向车辆上方。
以上是对本申请涉及到的部分内容以及概念所作的简单介绍。
当前，为了确定第一车辆周围的第二车辆的三维信息，提出了如下三种确定车辆信息的方法。分别为：方法1、车辆2D检测，方法2、车辆双目3D检测，以及方法3、车辆激光点云检测。以下，分别对方法1、方法2、以及方法3进行详细说明。
方法1、车辆2D检测
车辆2D检测为：第一车辆确定第二车辆在待检测图像中显示的图像信息；第一车辆以矩形框的形式，将第二车辆在待检测图像中显示的图像信息框出；第一车辆根据矩形框的下边沿的位置，计算第二车辆距离第一车辆的距离，确定第二车辆与第一车辆的相对位置。
由此可知，在该方法中，第一车辆仅能确定第二车辆相对于第一车辆的位置信息。但是，在智能驾驶场景中，车辆除了需要确定车辆的位置信息之外，还需要确定出车辆的大小，方向等信息，以判断周围车辆是否对自身的行驶造成干扰。
因此，依靠简单的车辆2D检测，无法满足智能驾驶场景中第一车辆对其他车辆信息的需求。
方法2、车辆双目3D检测
双目3D检测通过确定两个位于不同位置的图像采集装置采集到的检测对象的图像的差别，可以获得检测对象的深度信息。通过建立图像中相同点的对应关系，将同一空间物理点在不同图像中的映像点对应起来，形成视差(Disparity)图像，并可以根据视差图像，确定检测对象的3D信息。
车辆双目3D检测为：第一车辆采用双目摄像头，分别从两个角度采集第二车辆的两张图像。第一车辆根据第二车辆上的相同的点在两张图像中的位置的偏差，计算出第二车辆的三维信息。通过双目3D检测算法能够较为准确的计算出第二车辆的大小，方向以及相对于第一车辆的位置信息。
但是双目摄像头的硬件设备昂贵，应用到智能车辆上的双目摄像头的制作要求高，且目前的对于第二车辆3D信息确定过程中所使用的算法需要较高的图像标注成本，以及计算量。
方法3、车辆激光点云检测
当一束激光照射到物体表面时，所反射的激光会携带方位、距离等信息。若将激光束按照某种轨迹进行扫描，便会边扫描边记录到反射的激光点信息，由于扫描极为精细，则能够得到大量的激光点，因而就可形成激光点云。
车辆激光点云检测为：第一车辆向周围发射激光，扫描周围的检测对象。第一车辆接收周围检测对象返回的激光点云数据，这些点云数据中包括第二车辆返回的点云数据，以及其他检测对象返回的点云数据。第一车辆采用机器学习或者深度学习等算 法，将第二车辆返回的激光点云数据映射为某种数据结构。第一车辆提取出这些数据中每个点或特征，并根据这些特征对点云数据进行聚类，将相似的点云归为一类。第一车辆将聚类后的点云输入到相应的分类器中进行分类识别，确定第二车辆的点云数据。第一车辆将第二车辆的点云数据映射回三维点云数据中，构建第二车辆的3D包围框，确定第二车辆的三维信息。
车辆激光点云检测虽然具有很好的检测精度，但是激光雷达的硬件成本较高，且点云数据的数据计算量较大，需要耗费大量的计算资源，占用第一车辆大量的GPU资源。
为了解决现有技术中，第一车辆确定第二车辆的二维信息时，无法准确的确定第二车辆的大小和方向信息，第一车辆确定第二车辆的三维信息时，采用车辆双目3D检测或者车辆激光点云检测时，硬件成本高，计算复杂度高的问题。本申请实施例提供了一种确定检测对象的三维信息的方法，第一车辆能够根据采集到的待检测图像，确定第一检测对象的可通行区域边界以及触地线，进一步的，第一车辆根据第一检测对象的可通行区域边界，以及触地线，确定第一检测对象在二维图像中表征出的三维信息。
上述待检测图像可以为单目摄像头采集的二维图像。这样，第一车辆通过单目摄像头采集第一检测对象的图像信息即可确定第一检测对象的三维信息。相比较于现有技术中第一车辆需要依赖双目摄像头采集第一检测对象的图像信息以确定第一检测对象的三维信息的方法，或者第一车辆依赖激光雷达确定第一检测对象的三维信息的方法，本申请中第一车辆采用单目摄像头采集第一检测对象的图像信息确定第一检测对象的三维信息，能够大大降低确定第一检测对象的三维信息的硬件成本。
此外，本申请提供的确定检测对象的三维信息的方法，第一车辆只需标记第一检测对象的可通行区域边界，并根据第一检测对象的可通行区域边界确定第一检测对象的触地线。第一车辆可以根据第一检测对象的可通行区域边界，以及触地线，结合第一检测对象在待检测图像中的视觉关系等，确定第一检测对象在二维图像中表征出的三维信息。因此，本申请提供的确定检测对象的三维信息的方法，无需第一车辆进行其他额外的数据标注训练，从而降低了确定第一检测对象的三维信息的计算量，以及降低了确定第一检测对象的三维信息占用的图形处理器GPU资源。
以下，将对本申请实施例提供的确定检测对象的三维信息的方法进行详细说明，如图7所示，该方法包括：
S101、第一车辆获取待检测图像。
其中，待检测图像包括第一检测对象。
在智能驾驶领域，检测对象可以为车辆，行人，障碍物等。在本申请实施例中，以检测对象为第二车辆为例，进行说明。
上述待检测图像可以为车载的图像采集装置采集到的图片。车载图像采集装置通常用于采集位于车辆前方的其他车辆；或者，车载图像采集装置也可以通过采集车辆360°全方位的图像，以获得车辆周围所有其他车辆的信息。
需要指出的是，本申请实施例所记载的图像采集装置可以为单目摄像头，当第一车辆执行本申请实施例提供的确定检测对象的三维信息的方法时，该第一车辆可以为 设置在第一车辆中的车载终端设备，或者其他具有数据处理能力的设备。
S102、第一车辆确定第一检测对象的可通行区域边界，以及第一检测对象的触地线。
其中，第一检测对象的可通行区域边界包括第一检测对象在待检测图像中的边界。第一检测对象的触地线为第一检测对象与地面的交点的连线。
第一检测对象的可通行区域边界为将待检测图像输入到神经网络模型之后，由神经网络模型输出的第一检测对象的可通行区域边界。
当第一检测对象为第二车辆时，第二车辆的触地线的数量与第二车辆在待检测图像中示出的侧面的数量有关。
如图8a所示，第一检测对象为在待检测图像中位于第一车辆右前方的车辆，待检测图像中示出了第二车辆的左侧面和后侧面的情况下，第二车辆的触地线包括两条触地线，分别为第二车辆左侧面的触地线和第二车辆后侧面的触地线。
第二车辆左侧面的触地线为：第二车辆左前侧的轮胎的触地点和第二车辆左后侧的轮胎的触地点之间的连线。
第二车辆后侧面的触地线为：第二车辆左后侧的轮胎的触地点和第二车辆右后侧的轮胎的触地点之间的连线。
或者，如图8b所示，第一检测对象为在待检测图像中位于第一车辆正前方的车辆，待检测图像中仅示出了第二车辆的后侧面的情况下，第二车辆的触地线包括一条触地线，为第二车辆后侧面的触地线。
第二车辆的后侧面的触地线为：第二车辆左后侧的轮胎的触地点和第二车辆右后侧的轮胎的触地点之间的连线。
S103、第一车辆根据可通行区域边界，以及触地线，确定第一检测对象的三维信息。
第一检测对象的三维信息用于确定第一检测对象的大小、方向和相对位置中的至少一项。
第一检测对象的三维信息，用于表征第一检测对象在待检测图像中所示出的三维信息。第一车辆可以将第一检测对象在待检测图像中所示出的三维信息转换到三维坐标系中，以进一步确定第一检测对象的真实三维信息。
例如，在第一检测对象为第二车辆的情况下，第一车辆将第二车辆在待检测图像中所示出的三维信息转换到三维坐标系中，可以确定第二车辆的大小(例如第二车辆的长度，宽度)，第二车辆的方向(例如第二车辆的车头朝向，第二车辆可能的行驶方向)，第二车辆的在该三维坐标系中的位置。
需要指出的是，第一检测对象的相对位置，与第一车辆将第一检测对象转换到的三维坐标系有关。例如，在第一车辆将第一检测对象转换到第一车辆的车体坐标系时，第一检测对象的相对位置为第一检测对象相对于第一车辆的位置；在第一车辆将第一检测对象转换到世界坐标系时，第一检测对象的相对位置为第一检测对象的实际地理位置。
一种可能的实现方式中，第一检测对象的三维信息，包括多个点和多条线段。该多个点为第一检测对象在待检测图像中显示出的端点在地面上的投影。该多条线段中 至少包括第一检测对象的最外围边界在地面上的投影所产生的线段；或者，该多条线段为第一检测对象的在待检测图像中的轮廓线。第一车辆将该多条线段输入至第一车辆的车体坐标系中，可以确定第一检测对象的大小，方向和相对位置中的至少一项。
基于上述技术方案，本申请提供的确定检测对象的三维信息的方法，第一车辆能够根据采集到的待检测图像，确定第一检测对象的可通行区域边界以及触地线，进一步的，第一车辆根据第一检测对象的可通行区域边界，以及触地线，确定第一检测对象在二维图像中表征出的三维信息。
上述待检测图像可以为单目摄像头采集的二维图像。这样，第一车辆通过单目摄像头采集第一检测对象的图像信息即可确定第一检测对象的三维信息。相比较于现有技术中第一车辆需要依赖双目摄像头采集第一检测对象的图像信息以确定第一检测对象的三维信息的方法，本申请中第一车辆采用单目摄像头采集第一检测对象的图像信息确定第一检测对象的三维信息，能够大大降低确定第一检测对象的三维信息的硬件成本。
此外，本申请提供的确定检测对象的三维信息的方法，第一车辆只需标记第一检测对象的可通行区域边界，并根据第一检测对象的可通行区域边界确定第一检测对象的触地线。第一车辆可以根据第一检测对象的可通行区域边界，以及触地线，结合第一检测对象在待检测图像中的视觉关系等，确定第一检测对象在二维图像中表征出的三维信息。因此，本申请提供的确定检测对象的三维信息的方法，无需第一车辆进行其他额外的数据标注训练，从而降低了确定第一检测对象的三维信息的计算量，以及降低了确定第一检测对象的三维信息占用的图形处理器GPU资源。
结合图7，如图9所示，上述S102具体可以通过以下S1021-S1023实现。下面对S1021-S1023进行详细说明。
S1021、第一车辆将待检测图像输入神经网络模型中，得到L个点。
其中，待检测图像中通常包括一个或多个检测对象。上述L个点为该一个或多个检测对象的可通行区域边界上的点。L为正整数。
一种可能的实现方式中，上述神经网络模型，为预先训练好的神经网络模型。该神经网络模型具有标记待检测图像中检测对象的可通行区域边界的能力。可通行区域的边界即为待检测图像中的检测对象的边界。
具体来说，第一车辆获取待检测图像之后，调用神经网络模型，并将待检测图像输入到该神经网络模型中，输出L个点。该L个点即为待检测图像中检测对象的可通行区域边界的能力。
神经网络模型输出的L个点中的每个点可以对应一个标识。该标识用于表征该点位于检测对象的哪一侧。
举例来说，位于检测对象的左侧的点对应第一标识。相应的，该第一标识用于表征该点位于检测对象的左侧。
位于检测对象右侧的点对应第二标识。相应的，该第二标识用于表征该点位于检测对象的右侧。
位于检测对象的前侧的点对应第三标识。相应的，该第三标识用于表征该点位于检测对象的前侧。
位于检测对象的后侧的点对应第四标识。相应的，该第四标识用于表征该点位于检测对象的后侧。
S1022、第一车辆从该L个点中，确定出M个点。
该M个点为位于第一检测对象的可通行区域边界上的点。
一种具体的实现方式中，第一车辆根据待检测图像中的一个或多个检测对象，对该L个点进行分类，确定每个点所对应的检测对象。在此之后，第一车辆根据每个点对象的检测对象，确定对应于第一检测对象的M个点。该M个点即为位于第一检测对象的可通行区域边界上的点。M为正整数，且M小于等于L。
S1023、第一车辆拟合该M个点，确定第一检测对象的触地线。
一种可能的实现方式中，第一车辆可以采用随机抽样一致算法(random sample consensus，RANSAC)拟合算法，拟合确定目标对象的触地线。
具体来说，第一车辆可以采用RANSAC拟合算法，拟合确定目标对象的触地线的过程包括以下步骤a-步骤f，以下进行详细说明：
步骤a、第一车辆确定出位于第一检测对象的可通行区域边界，且具有相同标识的K个点，K为正整数。
步骤b、第一车辆从该K个点中随机选取T个点，并用最小二乘法拟合该T个点，得到一条直线。
步骤c、第一车辆确定K个点中除该T个点以外的每个点距离该直线的距离。
步骤d、第一车辆确定距离小于第一阈值的点为内群点，并确定内群点的个数。
步骤e、第一车辆多次执行上述步骤b-步骤d，确定多条直线，以及该多条直线中每条直线对应的内群点的个数。
步骤f、第一车辆确定上述多条直线中，对应的内群点的个数最多的直线，为第一检测对象的一个触地线。
需要指出的是，在上述步骤e中，第一车辆通过步骤b-步骤d确定的直线的数量越多，最终确定的结果的准确性越高。
基于上述技术方案，第一车辆能够根据待检测图像，采用神经网络模型，和相应的拟合算法，确定第一检测对象的可通行区域边界，以及第一检测对象的触地线。
需要说明的是，第一车辆的单目摄像头，能够拍摄到位于该单目摄像头前方的物体图像。在第二车辆位于该单目摄像头的正前方的位置时，第二车辆通常只有一个面能够被第一车辆的单目摄像头采集到。在第二车辆位于该单目摄像头前方，且偏离单目摄像头正前方的位置时，第二车辆通常有两个面能够被第一车辆的单目摄像头采集到。
因此，第一车辆采集到的第二车辆的图像包括以下两种场景：场景1、第一车辆采集到第二车辆的两个侧面。场景2、第一车辆采集到第二车辆的一个侧面。下面，分别对上述场景1和场景2进行详细说明：
场景1、第一车辆采集到第二车辆的两个侧面。
其中，第一车辆采集到第二车辆的图像信息，与单目摄像头采集的第一车辆的哪个方位的图像有关。
例如，当单目摄像头采集第一车辆的前方的图像时：
若第二车辆第一车辆同向行驶，且位于第一车辆的左前方，则单目摄像头可以采集到第二车辆的右侧面和后侧面。
若第二车辆与第一车辆同向行驶，且位于第一车辆的右前方，则单目摄像头可以采集到第二车辆的左侧面和后侧面。
若第二车辆与第一车辆相向行驶，且位于车辆的左前方，则单目摄像头可以采集到第二车辆的前侧面和左侧面。
若第二车辆与第一车辆相向行驶，且位于车辆的右前方，则单目摄像头可以采集到第二车辆的前侧面和右侧面。
又例如，单目摄像头采集第二车辆的左侧的图像时：
若第二车辆位于第一车辆左侧，且偏离单目摄像头的正前方，单目摄像头可以采集到第二车辆的右侧面，以及第二车辆的前侧面或者后侧面中的一个。
此外，单目摄像头还可以采集第二车辆的其他侧面的图像，本申请对此不在赘述。
场景2、第一车辆采集到第二车辆的一个侧面。
其中，第一车辆采集到第二车辆的图像信息，与单目摄像头采集的第一车辆的哪个方位的图像有关。
例如，当单目摄像头采集第一车辆的前方的图像时：

若第二车辆与第一车辆相向行驶，且位于第一车辆的正前方，则单目摄像头可以采集到第二车辆的前侧面。
若第一车辆向正北方向行驶，第二车辆向正东方向行驶，则单目摄像头可以采集到第二车辆的右侧面。
若第一车辆向正北方向行驶，第二车辆向正西方向行驶，则单目摄像头可以采集到第二车辆的左侧面。
又例如，单目摄像头采集第二车辆的左侧的图像时：
若第二车辆位于第一车辆左侧，且位于单目摄像头的正前方，单目摄像头可以采集到第二车辆的右侧面。
以上，记载了在不同场景下，第一车辆可以采集到的第二车辆的侧面的数量不同。
需要指出的是，当第一车辆采集到的第二车辆的侧面的数量不同时，第一车辆确定的第二车辆的可通行区域边界不同，第一车辆确定的第二车辆的触地线的数量不同，以及第一车辆确定的第二车辆的三维信息不同。
具体来说，在第一车辆采集到第二车辆的两个侧面的场景下：第一车辆确定的第二车辆的可通行区域边界为该两个侧面可通行区域边界。第一车辆确定的第二车辆的触地线包括第一触地线和第二触地线，第一触地线和第二触地线分别对应该两个侧面中的不同侧面。第一车辆确定的第二车辆的三维信息，包括该两个侧面组成的三维信息。

第三边界点为多个具有第三标识的边界点中，距离第三触地线的一端最远的点。
第四边界点为多个具有第三标识的边界点中，距离第三触地线的另一端最远的点。
结合上述S103，在情况2中，第一车辆根据上述S103确定的第一检测对象的三维信息根据第一检测对象对应的两个点和一条线确定。
两个点中的第一个点为第三边界点在地面上的投影。
两个点中的第二个点为第四边界点在地面上的投影。
结合图8，如图12所示，在情况2中，S103具体可以通过以下S1036-S1038实现，下面，对S1036-S1038进行详细说明。
S1036、第一车辆根据第三边界点和第三触地线，确定第一个点。
其中，第一个点为第三触地线与第五直线的交点。第五直线为过第三边界点，且与第三触地线垂直的直线。
一种具体的实现方式中，结合图13中示出的待检测图像中的第一检测对象，第一车辆确定第一检测对象的三维信息的第一个点的方法为：
步骤1、第一车辆确定第五直线。
第五直线为在待检测图像中过第三边界点，且与视平线垂直的直线。
一种实现方式中，第一车辆过第三边界点做视平线的垂线，第一车辆确定该垂线为第五直线。
步骤2、第一车辆确定第五直线与第三触地线的交点，为第一个点。
一种实现方式中，第一车辆做第三触地线的延长线，第三触地线的延长线与第五直线交于点e，第一车辆确定点e为第一个点。
S1037、第一车辆根据第四边界点和第三触地线，确定第二个点。
其中，第二个点为第三触地线与第六直线的交点。第六直线为过第四边界点，且与第三触地线垂直的直线。
一种具体的实现方式中，结合图13中示出的待检测图像中的第一检测对象，第一车辆确定第一检测对象的三维信息的第二个点的方法为：
步骤3、第一车辆确定第六直线。
其中，第六直线为在待检测图像中过第四边界点，且与视平线垂直的直线。
一种实现方式中，第一车辆过第四边界点做视平线的垂线，第一车辆确定该垂线为第六直线。
步骤4、第一车辆确定第六直线与第三触地线的交点，为第二个点。
一种实现方式中，第一车辆做第三触地线的延长线，第三触地线的延长线与第六直线交于点f，第一车辆确定点f为第二个点。
S1038、第一车辆根据第一个点和第二个点，确定第一条线。
一种实现方式中，如图13所示，第一车辆做一条分别以第一个点和第二个点为端点的线段c，第一车辆确定该线段c为第一条线。
基于上述技术方案，第一车辆能够根据第一检测对象的可通行区域边界，以及第一检测对象的触地线，确定第一检测对象的三维信息。
需要指出的是，上述三维信息是第一检测对象在待检测图像中所表征的三维信息。第一车辆需要确定第一检测对象的真实三维信息时，还需要将第一检测对象在待检测图像中所表征的三维信息带入带第一车辆的车体坐标系中，以使得第一车辆确定第一检测对象相对于第一车辆的位置，第一检测对象的大小(长、宽、高中的至少一项)，以及第一检测对象的朝向等信息。
具体来说，结合图7，如图9所示，在S103之后，该方法还包括：
S104、第一车辆将第一检测对象的三维信息输入车体坐标系中，确定第一检测对象的大小、方向和相对位置中的至少一项。
一种具体的实现方式中，第一车辆根据待检测图像建立第一直角坐标系；待检测图像位于该第一直角坐标系中。该第一直角坐标系可以为预先为图像采集装置设置的矩阵，图像采集装置采集的图片均可以映射到该矩阵中。
第一车辆确定第一检测对象的三维信息的在第一之间坐标系中的坐标。在此之后，第一车辆确定图像采集装置的内参数和外参数。第一车辆根据图像采集装置的内参数和外参数，以及图像采集装置在车体坐标系中的位置，将第一检测对象的三维信息的在第一直角坐标系中的坐标转换为车体坐标系中的坐标。
第一车辆根据第一检测对象的三维信息在车体坐标系中的坐标，确定第一检测对象的位置，运动方向，大小等信息。
其中，图像采集装置的内参数，用于表征与图像采集装置自身相关的一些参数，例如图像采集装置的焦距，像素大小等。
图像采集装置的外参数，用于表征图像采集装置在世界坐标系中的参数，例如图像采集装置在世界坐标系中的位置，旋转方向等。
需要说明的是，第一车辆中预先设置有图像采集装置的内参矩阵和外参矩阵。第一车辆在将车体坐标系中的一个坐标点转换为第一之间坐标系中的一个坐标点(记为第一坐标点)时：第一车辆将该第一坐标点依次与外参矩阵和内参矩阵相乘，即可得到第一坐标点在第一直角坐标系中对应的坐标点。第一车辆在根据第一直角坐标系中的坐标点求其在车体坐标系中对应的点时，只需执行与上述相反的运算过程，即可根据第一直角坐标系中的坐标点，确定其在车体坐标系中对应的点。
需要指出的是，在S105之后，第一车辆确定的第一检测对象的大小，包括第一监测对象的长度和宽度。
为了确定第一检测对象的高度，第一车辆可以根据第一检测对象的类型，确定第一监测对象的高度。
举例来说，在第一检测对象是第二车辆的情况下，第一车辆识别第二车辆的车辆 类型，并根据该车辆的类型确定车辆的高度。
一种示例，第二车辆的车辆类型为车辆的级别，例如：微型车、小型车、紧凑型车、中型车、中大型车、大型车、小型运动型多用途汽车(sport utility vehicle，SUV)、紧凑型SUV、中型SUV、中大型SUV、大型SUV、紧凑型多用途汽车(multi purpose vehicles，MPV)、中型MPV、中大型MPV、大型MPV、跑车、皮卡、微面、轻客、微卡等。
第一车辆中预先配置有各个等级车辆的标准尺寸，在第一车辆确定第二车辆的车辆等级之后，根据第二车辆的车辆等级，确定第二车辆的高度。
又一种示例，第二车辆的车辆类型为车辆的型号(例如，车辆品牌+具体车型)。第一车辆中预先配置有各个型号的车辆的标准尺寸，在第一车辆确定第二车辆的车辆型号之后，根据第二车辆的车辆型号，确定第二车辆的高度。
需要指出的是，根据上述方法，第一车辆同样可以根据第二车辆的类型确定第二车辆的长度和宽度。第一车辆可以根据通过该方法确定的第二车辆的长度和宽度，以及通过第二车辆在待检测图像中的三维信息确定的长度和宽度互相验证，确定第二车辆的准确长度和宽度。
一种可能的实现方式中，在S105之后，第一车辆确定待检测图像中的全部车辆的位置，大小以及运动方向。第一车辆根据全部车辆的位置，大小以及运动方向，以及第一车辆中其他设备确定的当前道路信息，障碍信息，车辆的目的信息等，规划第一车辆的行驶路线。
第一车辆确定第一车辆的行驶路线之后，根据该第一行驶路线生成第一控制指令。第一控制指令用于指示第一车辆根据规划好的行驶路线行驶。
第一车辆向第一车辆下发该第一控制指令。第一车辆根据第一车辆下发的控制指令进行智能驾驶。
基于上述技术方案，第一车辆可以根据第二车辆的三维信息确定第二车辆的大小，方向，以及第二车辆相对于第一车辆的位置。在此之后，第一车辆可以根据这些信息，规划第一车辆的行驶路线，实现智能驾驶。
