System information

  • OS Platform and Distribution (e.g., Linux Ubuntu 20.04):
  • Apollo installed from (master):
  • Apollo version (9.0):
  • Output of apollo.sh config if on master branch:

Steps to reproduce the issue:

  • Please use bullet points and include as much details as possible:
    目前也是刚学习Apollo,有一个自己组装的底盘小车,镭神C16激光雷达,多个摄像头。想着自己集成起来,有一些问题想请教下各位大佬:

一、感知模块:

1、我们现在没有底盘不能跑起来实车,但是有雷达和相机。我看现在9.0雷达感知分为多个组件,那每个组件是否可以只接上我的雷达就能单独启动调试呢?只有雷达的话是否启动lidar_detection.bag就可以看到实时感知效果呢?

2、我们用的板子是Jetson AGX Orin,源码安装后在这个板子上启动9.0无法打开dreamview+也就是plus版本,只能启动之前的版本,检查了启动文件,按照开发文档的命令也无法打开plus版。

3、尝试启动雷达感知中单独的组件比如pointcloud_preprocess.dag,将dag文件中的readers的channel改为自己雷达的点云通道后,出现坐标转换can not find transform的问题,报错中提及child_frame_id:front_6mm,这个不是相机的坐标系嘛?

4、接入摄像头,能过调用并在dreamview中显示图像,之后打开static_transform 与muti_stage_camera模块,static_transform无报错信息,但是多阶段相机检测模块显示成功加载yolo模型后,会出现如下的爆红信息,(如下图所示)但是并未停止。此外,obstacle通道自动打开,显示变绿。但是进去后通道中的message信息不完整,没有perception_obstacle[] 的信息。()

5、当启动traffic_light模块时,初始化时出现如下图错误。

二、规划模块:

1、在没有能够满足Apollo线控底盘的情况下,比如只有Jeston AGX Orin和一个STM32控制的电机小车底盘(有CAN接收器),这种情况能否适配Apollo的线控底盘标准呢?

2、如果不连接车辆底盘,只有Jeston AGX Orin、雷达、摄像头、北斗星通的导航、4G路由,这种情况下能否启动Apollo并成功集成其余感知、定位的硬件?比如集成好之后,雷达和摄像头能看到实时的感知效果,规划模块能够规划路径但不用传输到控制?
