ROS 2 compatible & What should be the ideal frequency for IMU and camera?

[serkanMzlm]

1 - Will it be made compatible with ROS2?
2 - What should be the ideal frequency for IMU and camera?

[serkanMzlm]

As I converted the code to ROS 2, I conducted experiments with the 'V1_01_easy' bag file, and the output turned out to be different from ROS 1. Upon inspecting the output data, I noticed that the data published from the feature_tracker part remains the same, while the position data published from the VINS estimator part appears to be significantly larger, despite the orientation data being similar.

ROS:

• /imu0 hz: 200
• /cam0/image_raw hz: 19.9

ROS2:

• /imu0 hz: 134
• /cam0/image_raw hz: 19.9

@serkanMzlm I wanted to ask that you converted it for which ubuntu and ros2 versions? Was it for ubuntu 20.04 and ros2 foxy or some other?

[serkanMzlm]

@YasheerahYaqoot
System:
Ubuntu: 22.04
ROS2: Humble

[YasheerahYaqoot]

@serkanMzlm Thank you!.
Also, can you tell me what libraries did you install? Ceres 2.1.0? Did you install opencv with CUDA or Eigen 3.3.9?

[serkanMzlm]

@YasheerahYaqoot Ceres, opencv and Eigen are installed, but I don't know their versions, but it is most likely the latest version.

[YasheerahYaqoot]

@serkanMzlm I m having problem in installing opencv. It gives error when i run this command : make -j8. Can you tell me how did you install it?

[serkanMzlm]

@YasheerahYaqoot Why are you trying to install from source?
Can you post a screenshot of the error?
After all the requirements are met, the packages need to be built using colcon build

sudo apt-get install -y libopencv-dev

@YasheerahYaqoot System: Ubuntu: 22.04 ROS2: Humble

I also want to convert this code to ROS2 hubmble in ubuntu22.04，I don‘’t know if we can discuss with each other. and my e-mail:[email protected]

[YasheerahYaqoot]

@serkanMzlm I did install every package and when I build the packages it gives me error. I removed everything for now. Will post a screenshot after doing it again. I m cloning your repo and installing all the dependencies and libraries and then building the package.

[YasheerahYaqoot]

@DMUZhangXianglong Yes that would be great! I will email you my process and my problems and then we can try doing it together.

[YasheerahYaqoot]

@serkanMzlm I get this error

[serkanMzlm]

@YasheerahYaqoot Your error is due to performing the build sequence incorrectly. First, the camodocal package needs to be built. To do this, run the command colcon build --packages-select camodocal. After building this package, you need to source it into the system. To do this, run . install/setup.bash Then, you need to build the required packages.

[serkanMzlm]

@YasheerahYaqoot and @DMUZhangXianglong , if you want, I can show you the build part on Sunday. Then, we can work together to resolve the errors causing issues in the system.

[YasheerahYaqoot]

@serkanMzlm Yes please, that would be very helpful. I think the issue is in the building of packages. I have tried several times but I am unable to do it. Let me know when you are available.

[serkanMzlm]

@serkanMzlmBu hatayı alıyorum

The cause of this error is the build order. First, please build the camodocal package.

[YasheerahYaqoot]

Maybe on Sunday you can help me with the necessary libraries and correct installing, building and sourcing since I m very new to this.

[YasheerahYaqoot]

Ok so, I was able to build camodocal. And now when I finally build the worskpace it gives me error.

[serkanMzlm]

@YasheerahYaqoot Installation steps:
1- Download the ROS2 branch on the GitHub page

git clone [email protected]:serkanMzlm/VINS-Mono.git -b ros2

2-

cd VINS-Mono
colcon build --packages-select camodocal config
. install/setup.bash

colcon build --packages-select feature_tracker vins_estimator pose_graph

If you have followed these steps, it should build without any issues.

[YasheerahYaqoot]

I am trying to do it on orangepi 5. The package is built but it does not launch rviz.

[serkanMzlm]

@YasheerahYaqoot The RViz part is still for ROS1; I haven't adapted it for ROS2. Running it manually and selecting the necessary packages should be sufficient.

Will you use KITTI or do you have intel realsense?

[DMUZhangXianglong]

@DMUZhangXianglong Yes that would be great! I will email you my process and my problems and then we can try doing it together.

Is it possible to use instant messaging software for communication, such as WeChat

[YasheerahYaqoot]

@serkanMzlm I have a simple USB camera. But first I want to test it on the existing dataset. What should I run to know that the package is installed correctly and working fine.

[YasheerahYaqoot]

@DMUZhangXianglong I am available on Telegram.

[serkanMzlm]

@YasheerahYaqoot The reason for opening this topic is that I converted all ROS1 code to ROS2 and ensured it builds without errors. However, there is an issue with one package. I run the code, and it works without any problems, but the resulting mapping is not the same as the graph in ROS1. I opened this topic so that the developers can review the ROS2 code and identify the error.

Additionally, I recommend trying the OpenVINS code because OpenVINS uses resources more efficiently and has support for ROS2
