Can you add a syncrhonized RGB-D topic?

[JunweiLiang]

Hi,

Currently the color image and depth image are published in separate topics. Can you add a RGB-D topic, where the color and depth images are synchronized and sent in a single message?

You already have RGBD.msg here. Realsense provides this RGB-D topic as shown here.

Currently, you need an ApproximateTimeSynchronizer to achieve this as in here.

Thanks! Junwei
