[BUG] {colcon build fail - opencv version stderr}

[Serafadam]

Hi, as ROS Foxy is EOL it is no longer officially supported, I would recommend switching to Humble if it is possible, either via apt or Docker image. If that is not possible, you could try updating depthai_filters' CMakeLists.txt based on current Humble version.

Thank you, doing that solved that issue. However, now I am getting the following issue related to opencv. I have opencv version 4.2.0. Do I need to make a change to the opencv files?

Hi, I think you do not have modules from opencv_contrib module, you should install it to get them.

I installed the opencv_contrib module but have this error when building depthai_filters. I have verified the ximgproc file is present.

Starting >>> depthai_filters

Hi, I think this might be issue with Jetson as I've seen similar issues on Nvidia forums, could you try checking if their solutions work?
