请参阅图1至图5，本申请提供了一种车载多目组件100，车载多目组件100包括支架10、第一电路板21、第二电路板22、第一镜头31和第二镜头32；第一电路板21固定在支架10上，第一电路板21上设置有第一图像传感器41；第二电路板22固定在支架10上，第二电路板22上设置有第二图像传感器42；第一镜头31固定在支架10上，第一镜头31与第一图像传感器41对准；第二镜头32固定在支架10上，第二镜头32与第二图像传感器42对准；其中，第一镜头31、第一电路板21、第一图像传感器41能够形成第一拍摄组件，第二镜头32、第二电路板22、第二图像传感器42能够形成第二拍摄组件，第一拍摄组件与第二拍摄组件具有重叠的第一观测范围，第一拍摄组件与第二拍摄组件用于测量第一观测范围内的场景对象与自身的距离。
请参阅图6，本申请实施方式的组装方法，用于组装车载多目组件100，车载多目组件100包括支架10、第一电路板21、第二电路板22、第一镜头31和第二镜头32，第一电路板21上设置有第一图像传感器41；第二电路板22上设置有第二图像传感器42；组装方法包括：
001，将第一电路板21固定在支架10上；
002，将第二电路板22固定在支架10上；
003，将第一镜头31固定在支架10上，第一镜头31与第一图像传感器41对准；
004，将第二镜头32固定在支架10上，第二镜头32与第二图像传感器42对准；
其中，第一镜头31、第一电路板21、第一图像传感器41能够形成第一拍摄组件，第二镜头32、第二电路板22、第二图像传感器42能够形成第二拍摄组件，第一拍摄组件与第二拍摄组件具有重叠的第一观测范围，第一拍摄组件与第二拍摄组件用于测量第一观测范围内的场景对象与自身的距离。
所述支架10整体呈矩形，支架10上侧边缘形成多个定位结构，支架10可以通过多个定位结构安装在其他位置，具体可以采用螺栓连接、铆接、胶粘等连接方式。
第一电路板21和第二电路板22间隔一定距离固定在支架10上左右对称的位置，第一图像传感器41和第二图像传感器42分别设置在第一电路板21和第二电路板22上，第一镜头31和第二镜头32呈圆柱体状并分别与第一图像传感器41和第二图像传感器42对准，第一图像传感器41和第二图像传感器42可以接收第一镜头31和第二镜头32采集到的图像，并融合车速、IMU等信息配合第一电路板21和第二电路板22的运算功能实现基于双目视觉的感知方案。
第一镜头31、第一电路板21、第一图像传感器41形成第一拍摄组件，第二镜头32、第二电路板22、第二图像传感器42形成第二拍摄组件，由于第一镜头31与第二镜头32朝向相同方向并间隔一定距离、镜头的视场角也相同，故第一镜头31和第二镜头32采集图像的范围会有部分重叠，称重叠部分为第一观测范围，第一拍摄组件与第二拍摄组件用于测量第一观测范围内的场景对象与自身的距离。
在一种实施方式中，第一拍摄组件和第二拍摄组件可以采用短焦模组相机或长焦模组相机，第一拍摄组件与第二拍摄组件在支架10上的排列方式不固定。其中，第一拍摄组件与第二拍摄组件均采用短焦模组相机时，重叠的第一观测范围呈沿车辆1000宽度方向延伸的胖三角形状，以便能够获取近景视野及准确的近景距离。而第一拍摄组件与第二拍摄组件均采用长焦模组相机时，重叠的第二观测范围呈沿车辆1000长度方向延伸的细长三角形状，以便能够获取远景视野及准确的远景距离。
需要说明的是，第一拍摄组件和第二拍摄组件还可以是广角模组相机、近景模组相机、中景模组相机及远景模组相机的组合，即通过广角模组相机拍摄广角视频和图像，能够看到较大范围的景物，而通过近景模组相机侧重于拍摄车辆1000较近区域(如10米范围内)的图像和视频；中景模组相机相对于近景相机而言距离稍远，如与车辆1000的距离为10-50米之间的景物；而远景模组相机则会远些，如50米外。总体来说，本申请的第一拍摄组件和第二拍摄组件不仅仅限制于短焦模组相机和长焦模组相机的组合。
其中，第一拍摄组件与第二拍摄组件的数量不做限定，在测量观测范围内的场景对象与车辆1000的距离可以通过第一拍摄组件与第二拍摄组件重叠的区域进行计算，以提高测量的精度。
如此，第一电路板21、第二电路板22、第一镜头31和第二镜头32直接固定在支架10上，从而使得车载多目组件100的结构简单，第一图像传感器41、第一镜头31、第二图像传感器42和第二镜头32形成的双目摄像头的位置偏差较小，从而能够提高双目摄像头的测距精度。
