Localization using Monocular RGB Camera

[zayedreply]

Hi, I am interested in doing the localization using a monocular rgb camera. I have mapped the area using a realsense d455 rgbd camera. I used the rgb + depth + imu to make the area. However i am not managing to do the localization with the rgb camera only.

Is it possible to do so? For the mapping I have used the ros2 launch file provided, with just the topic names changed.

Thanks in advance
