Perception SiG Maintainers Still Maintaining?


This SiG seems like it hasn’t seen any real conversation for a while and the GitHub group definitely needs some love (almost 100 pull requests are dead or un-reviewed across multiple repos). Is anyone still out there? Do we need to recruit some new maintainers?

No offense intended to any maintainers out there - everyone gets busy and priorities change. However, this is a pretty important group of repos for the entire community and I want to make sure they’re taken care of regularly.

ROS orphaned package maintainer info. REP 152 for review

We’ve started work on some of the ROS2 ports, so there is some activity on that side, but I haven’t taken on any sort of maintainership for the ROS1 bits yet.


Are you the only maintainer in the group? If so, I can offer my help with maintenance.


@JWhitleyAStuff what is the perception sig project? I could not find such project in github. would you please help to share the project link? thanks.

we are contributing on ros2 perception porting, and tracking the status in the thread here: ROS2 perception porting status


@yechun - I’m specifically talking about the ROS Perception Special Interest Group (formerly at!forum/ros-sig-perception). The focus of this group appears to have been developing/maintaining the drivers/nodes at However, as I said, there are many repos there in need of attention.


I have some deep familiarity with slam/open karto & gmapping as well as SBA that I would be more than happy to jump on and help maintain if help are needed in those areas.


@rtoris, @Vincent_Rabaud, @Paul_Bovbel, and Ken Torris appear to be the previous or current maintainers of the packages that need issues and PRs reviewed. Not trying to shame anyone, just want to get some visibility and, hopefully, responses from the current maintainers to see what can be done. The focus of this tread is on the maintenance of packages like image_pipeline and usb_cam which are used by many, many individuals and organizations today, though I am having a specific problem with image_pipeline on 18.04.

@tfoote - Is there any way to get this run up the flagpole and get some visibility to have new maintainers handle these packages?


About image_pipeline, we have already taken resources on porting it for ROS2. We also see there are 74 issues and 29 PRs have no updates for a long time. Don’t know if currently maintainers and OSRF have any plans for maintaining? If you could approve, we would like to be the new maintainer of this package.


@tfoote / @esteve / @dirk-thomas - Can anyone help? There are bugs in image_pipeline that are currently breaking important nodes like image_view for Melodic (see and I can’t get any response from anyone on this issue.


image_view have quite severe problem in Melodic.
image_view does not work with this PR but still waiting for review.
I need maintainers to solve this problem.
