我在运行"rviz -d ego_rviz.rviz"是rviz没有出现点云图 ![2022-05-10 13-04-29 的屏幕截图](https://user-images.githubusercontent.com/70137881/167547278-31ccab94-78cf-4e7e-9ad9-c7a22bc3e512.png) 这是运行后的rviz 有解决办法吗

肖老师,我打算做陆空无人机,想对您那个ris_realsense_camera sdf模型加四个地面轮子,但修改后gazebo就加载不出修改后的无人机模型了,想问您那个sdf模型是如何建立的?

當我在 SITL 中運行多輛車時,他們可以武裝但無法開始任務。 當我執行鍵盤控制時也是如此 請問要如何解決 ![145558494-f2e9b292-a123-44df-9588-563a3156b1e9](https://user-images.githubusercontent.com/83861951/145699315-1bc79f7c-5bba-4e3e-a956-410068b0a651.png)

老师您好,我在执行: roslaunch darknet_ros task1.launch和roslaunch px4 outdoor1.launch的时候,并不会出现yolo窗口(如下所示只有飞机前面出现图片),然后px4仿真这个界面出现报错以及进程已经died ,请问是不是typhoon模型的问题 ![图片](https://user-images.githubusercontent.com/84238372/236504064-07aef624-0a01-45fc-8aba-712e08447b3d.png) ![图片](https://user-images.githubusercontent.com/84238372/236504158-e235f5bb-4df7-475d-b475-1708573e0d0d.png) ![图片](https://user-images.githubusercontent.com/84238372/236504271-d1178558-67da-4ccb-af4e-82d9ab4f5ffb.png)

在修改sitl_gazebo中的gazebo_gimbal_controller_plugin.cpp后再次编译时报错, 报错信息有两条,如下: 1. ERROR [param] Parameter COM_CPU_MAX not found. 2. [Err] [InsertModelWidget.cc:426] Missing model.config for model "/home/santu/code/PX4_Firmware//Tools/sitl_gazebo/models/livox_mid40" [Err] [InsertModelWidget.cc:426] Missing model.config for model "/home/santu/code/PX4_Firmware/Tools/sitl_gazebo/models/livox_mid40" (此报错信息出现了两次) 此时gazebo已经可以正常运行,请问怎么处理这两条报错信息?

配置好平台后用键盘控制无人机飞行反应很迟钝或者没有反应

版本v1.11,按照文档建立通信后启动键盘控制,速度调到0.3以上进入offboard并启动,升高后按s进入悬停模式,过一会无人机就开始自动乱飞乱撞。

肖老师,您好,我在做集群运动规划时候发现使用vins-fusion传回点云的时候会出现:无人机在前面空旷的时候会显示出无人机在点云中,但是前面只要有障碍物就只会显示障碍物的点云,不会显示无人机在点云中。导致在进行运动规划时显示无人机在障碍物中而停止规划。如下面两个图所示: ![8cb6a898c34fe50dcda4951ca992b6f](https://user-images.githubusercontent.com/45734208/237041785-8c0cbcd1-f6fb-41c7-b14f-002ef325ed51.png) ![18e0a102265747e72fb1747ed223060](https://user-images.githubusercontent.com/45734208/237041819-4717d12b-21c0-4fa6-a20c-5a97fadd5321.png) 在终端有下面这个警告,不知道与这个有没有关系。没有报其他错误。 ![image](https://user-images.githubusercontent.com/45734208/237042526-e415f261-b419-4a4a-b3e3-e3bddc986e2f.png) 集群中的每个无人机都会有这个警告 ![image](https://user-images.githubusercontent.com/45734208/237046667-f15f8a9d-6cae-4956-bb03-1d3cdad85f88.png)
