is there any way to sovle these ?

Hello,

I was working with your dev/add_ros_bridge branch and the ROS bridge source code. I followed the README instructions and installed all the necessary dependencies. However, when I run the code with the following command: roslaunch carla_ros_bridge client_with_rviz.launch, I get the following error:

    assert len(raw_data) == 4 * width * height
AssertionError

Here is the whole entire error message:

Thanks for your time and attention. Thanks for the ROS bridge implemenation. Let me know if you need other details.

Hi George,

I am using the pre-compiled version of Carla version 0.8.2 (I have not built it from the scratch in my system).

I was trying to implement carla_ros_bridge by following the steps given in the link #4

But I am getting the below error.

kk@kk-Lenovo-ideapad-320-15ISK:~/ros/catkin_ws_for_carla$ rostest carla_ros_bridge ros_bridge_client.test
[ros_bridge_client.test] is neither a launch file in package [carla_ros_bridge] nor is [carla_ros_bridge] a launch file name
kk@kk-Lenovo-ideapad-320-15ISK:~/ros/catkin_ws_for_carla$ 

Does this method works on the pre-compiled Carla or do I have to build Carla from github code ?

Thank you,
KK

Hi George,
I am working on Carla and ROS Bridge. I would like to integrate an updated version of your Bridge inside a Docker. Unfortunately this Docker (coming from APOLLO platform) embeds an older version of ROS which is Indigo (2014) instead of ROS Kinetic.
Do you think is it possible to make the ROS Bridge working on ROS Indigo inside a Docker?

Many thanks for your support,
Regards
Alberto

Hi, @laurent-george,
do you have an idea how can I get "ring" data (index of ring similar to what velodyne device provides) for each point of the simulated lidar?
I was looking at your implementation of ros bridge, probably you could point out if is it possible to do in ros bridge or require some efforts on carla code side? I very appreciate any information.
