2021-06-20 06:15:01 -0500 | marked best answer | sensor_msgs/Image This is my first time dealing with sensor_msgs/Image. I am using ros melodic in ubuntu 18.04. I tried to subscribe the content of sensor_msgs/Image and tried to visualize the data from the msg for validating the image. it cunfused me when I print the width, height , and the size of the matrice data in sensor_msgs/Image. Why is the size value of matrice data in that msg different with height x width value ? Could anyone explain me about this ? (As I know the data is in the type of std::vector so I want to arrange it by dividing the data to an array[height][width] so I can validate and visualize those datas in Matlab) |

2021-06-04 11:23:00 -0500 | marked best answer | Frame does not exist when run Gazebo I am using ubuntu 18.04, ros melodic to simulate my URDF robot in gazebo. Then I create a dynamic node to move the robot. When I publish gazebo_msgs/ModelState with reference_frame set as "world_ned" in the dynamic node I created before, I was getting an error : "Updating ModelState: for model[MyrobotName], specified reference frame entity [world_ned] does not exist " , even though I already used a static_transform_publisher in my launch file. But when I simulate it in my rviz, there is no error like I said before. This is my tf tree : and this is my launch file : Does anyone know how to solve it ? |
